CPTF Statement Supporting Maryland House Bill 1098
To Ban State Funds for Artificial Turf and Playgrounds
March 5, 2020

Diana Zuckerman, PhD, President

Thank you for the opportunity to express our strong support for of HB 1098, to restrict the funding of additional artificial turf fields and playground surfaces in Maryland.

As a long-time resident of Montgomery County and president of the National Center for Health Research (NCHR), I am hoping that this bill will finally get the support it deserves.  NCHR is a non-profit public health organization which analyzes and explains scientific and medical information that can be used to improve policies, programs, services, and products.

Our organization has been testifying and writing about the dangers of synthetic turf and playground surfaces for several years, and we’ve testified before state, local and federal legislative bodies and regulatory agencies.  Our scientific staff has reviewed all publicly available scientific studies pertaining to the health impact of the lead and toxic chemicals that are in artificial turf and playground surfaces, compared to natural surfaces such as grass and engineered wood fiber.

In the last year, scientists have reported finding potentially dangerous levels of lead in artificial turf fields and playground surfaces.  In addition, plastic and synthetic rubber are made with different types of hormone-disrupting chemicals, some of which are known to be particularly harmful to growing children.  Scientists at the National Institute of Environmental Health Sciences, which is an institute of NIH, have concluded that these chemicals can be threats to health even at low levels.  According to research at Yale University, 20% of the 96 chemicals they found in samples at five different synthetic turf companies were classified as probable carcinogens.[1]

Manufacturers and advocates for synthetic turf often state that artificial turf has been declared safe by federal authorities.  That is completely untrue.  It is essential to understand that there are no federal requirements for safety testing of these synthetic turf products before they are sold.   Although the EPA and the federal Consumer Product Safety Commission are jointly studying the chemicals used in these products, they have not released any data on studies of children exposed to these fields and playgrounds day after day and week after week.

We commend you for considering how to reverse the dangerous trend of replacing natural fields and playground surfaces with materials that are dangerous to our children’s health, potentially dangerous to adult fertility and health, and bad for our environment.  In the last year, we’ve learned new information about lead and PFAS in artificial turf, as well as the risks of some of the newer infill materials that turf companies are using to replace tire crumb.

Tire crumb, used as infill for artificial turf fields and also used for colorful rubber playground surfaces, has well-known risks, containing lead as well as chemicals that have the potential to increase obesity; contribute to early puberty; cause attention problems such as ADHD; exacerbate asthma; and eventually cause cancer.  However, the plastic grass itself has dangerous levels of lead, PFAS, and other toxic chemicals as well.  PFAS are of particular concern because they are “forever chemicals” that get into the human body and are not metabolized, accumulating over the years. Replacing tire waste with silica, zeolite, and other materials also has substantial risks.

Federal agencies such as the EPA and the U.S. Consumer Product Safety Commission have been investigating the safety of these products.  Despite claims to the contrary, none have demonstrated that artificial turf is safe.  Although the Trump Administration’s EPA stated that there was no conclusive evidence that the levels of chemicals in artificial turf was harmful to children, they made it clear that their research was based on assumptions rather than scientific research on children.

Lead

The American Academy of Pediatrics states that no level of lead exposure is safe for children, because lead can cause cognitive damage even at low levels.  Some children are even more vulnerable than others, and that can be difficult or even impossible to predict.  Since lead has been found in tire crumb as well as new synthetic rubber, it is not surprising that numerous artificial turf fields and playgrounds made with either tire crumb or “virgin” rubber have been found to contain lead.  However, the Centers for Disease Control and Prevention (CDC) also warns that the “plastic grass” made with nylon or some other materials also contain lead.  Whether from infill or from plastic grass, the lead doesn’t just stay on the surface.  With wear, the turf materials turn to dust that is invisible to the eye but that children are breathing in when they play.

Why are chemicals that are banned from children’s toys allowed in artificial turf and rubber playground surfaces?

Synthetic rubber and plastic are made with different types of endocrine (hormone) disrupting chemicals (also called EDCs) and other toxins.  There is very good evidence regarding these chemicals in tire crumb, based on studies done at Yale and by the California Office of Environmental Health Hazard Assessment (OEHHA).

The California OEHHA conducted three laboratory studies to investigate the potential health risks to children from playground surfaces made from tire waste.1 The researchers created a chemical solution that mimicked the conditions of a child’s stomach and placed 10 grams of tire shreds in it for 21 hours at a temperature of 37°C.  One study mimicked a child touching the tire shreds and then touching her mouth by wiping recycled tire playground surfaces and measuring chemical levels on the wipes.  To evaluate skin contact alone, the researchers tested guinea pigs to see if rubber tire playground samples caused any health problems.  Results of the OEHHA studies showed that five chemicals, including four PAHs, were found on wipe samples.  One of the PAHs, “chrysene,” was higher than the risk level established by the OEHHA, and therefore, could possibly increase the chances of a child developing cancer.

A 2018 report by Yale scientists detected 92 chemicals in samples from 6 different artificial turf companies, including unused bags of tire crumb. Unfortunately, the health risks of most of these chemicals had never been studied.  However, 20% of the chemicals that had been tested are classified as probable carcinogens and 40% are irritants that can cause asthma or other breathing problems, or can irritate skin or eyes.[2]

There are numerous studies indicating that endocrine-disrupting chemicals found in rubber and plastic cause serious health problems. Scientists at the National Institute of Environmental Health Sciences (which is part of NIH) have concluded that unlike most other chemicals, hormone-disrupting chemicals can be dangerous at very low levels, and the exposures can also be dangerous when they combine with other exposures in our environment.

That is why the Consumer Product Safety Commission has banned numerous endocrine-disrupting chemicals from toys and products used by children. The products involved, such as pacifiers and teething toys, are banned even though they would result in very short-term exposures compared to artificial turf or playground surfaces.

A report warning about possible harm to people who are exposed to rubber and other hormone disrupting chemicals at work explains that these chemicals “can mimic or block hormones and disrupt the body’s normal function, resulting in the potential for numerous health effects… Similar to hormones, EDC can function at very low doses in a tissue-specific manner and may exert non-traditional dose–response because of the complicated dynamics of hormone receptor occupancy and saturation.”[3]

Studies are beginning to demonstrate the contribution of skin exposure to the development of respiratory sensitization and altered pulmonary function. Not only does skin exposure have the potential to contribute to total body burden of a chemical, but also the skin is a highly biologically active organ capable of chemical metabolism and the initiation of a cascade of immunological events, potentially leading to adverse outcomes in other organ systems.

Scientific Evidence of Cancer and Other Serious Harm

It is essential to distinguish between evidence of harm and evidence of safety. Like the Trump Administration’s EPA, companies that sell and install artificial turf often claim there is “no evidence children are harmed” or “no evidence that the fields cause cancer.” This is often misunderstood as meaning the products are safe or are proven to not cause harm. Neither is true.

It is true that there no clear evidence that an artificial turf field has caused specific children to develop cancer. However, the statement is misleading because it is virtually impossible to prove any chemical exposure causes one specific individual to develop cancer.

As an epidemiologist, I can also tell you that for decades there was no evidence that smoking or Agent Orange caused cancer.  It took many years to develop that evidence, and the same will be true for artificial turf.

I have testified about the risks of these materials at the U.S. Consumer Product Safety Commission, as well as previous Maryland hearings.  I am sorry to say that I have repeatedly seen and heard scientists paid by the turf industry and other turf industry lobbyists say things that are absolutely false.  They claim that these products are proven safe (not true) and that federal agencies have stated there are no health risks (also not true).

However, we know that the materials being used in artificial turf and rubber playground surfaces contain carcinogens, and when children are exposed to those carcinogens day after day, week after week, and year after year, they increase the chances of our children developing cancer, either in the next few years or later as adults.  That should be adequate reason not to install them in your community.  That’s why I have spoken out about the risks of artificial turf in my community and on a national level.  The question must be asked: if they had all the facts, would Maryland families choose to spend millions of taxpayer dollars on fields that are unhealthy and unsafe rather than well-designed natural grass fields?

Dangerously Hot and Hard Fields

Summers in Maryland can get hot.  Even when the temperature is a pleasant 80 degrees Fahrenheit, artificial turf and playground surfaces can reach 150 degrees or higher.  Obviously, turf and playground surfaces are likely to be even hotter than 150 degrees on a sunny 90 degree day.  That can cause “heat poisoning” as well as burns.

Artificial turf fields get hard as well.  Turf companies recommend annual tests at 10 locations on each turf field, using something called a Gmax scores.  A Gmax score over 200 is considered extremely dangerous and is considered by industry to pose a death risk.  However, the synthetic turf industry and ASTM (American Society for Testing and Materials), suggest scores should be even lower — below 165 to ensure safety comparable to a grass field.  Are Maryland communities paying to have these tests conducted on all public artificial turf fields?

The hardness of natural grass fields is substantially influenced by maintenance, rain and other weather; if the field gets hard, aeration water will make it safe again.  In contrast, once an artificial turf field has a Gmax score above 165, it needs to be replaced because while the scores can vary somewhat due to weather, the scores will inevitably get higher because the turf will get harder.  Gmax testing involves testing 10 different areas of a playing fields, to make sure all are considered safe.  Some officials average those 10 scores to determine safety; however, experts explain that is not appropriate.  If a child (or adult) falls, it can be at the hardest part of the field, which is why safety is determined based on each area tested.

Environmental Issues

In addition to the health risks to school children and athletes, approximately three tons of infill materials migrate off of each synthetic turf field into the greater environment each year.  About 2-5 metric tons of infill must be replaced every year for each field, meaning that tons of the infill have migrated off the field into grass, water, and our homes.  The fields also continuously shed microplastics as the plastic blades break down.[4,5] These materials may contain additives such as PAHs, flame retardants, UV inhibitors, etc., which can be toxic to marine and aquatic life; and microplastics are known to migrate into the oceans, food chain, and drinking water and can absorb and concentrate other toxins from the environment.[6,7,8]

Synthetic surfaces also create heat islands.[9,10]  In contrast, organically managed natural grass saves energy by dissipating heat, cooling the air, and reducing energy to cool nearby buildings.  Natural grass and soil protect groundwater quality, biodegrade polluting chemicals and bacteria, reduce surface water runoff, and abate noise and reduce glare.[11]

Envirofill and Alternative Infills

Envirofill artificial turf fields are advertised as “cooler” and “safer,” but our research indicates that these fields are still at least 30-50 degrees hotter than natural grass. Envirofill is composed of materials resembling plastic polymer pellets (similar in appearance to tic tacs) with silica inside. Silica is classified as a hazardous material according to OSHA regulations, and the American Academy of Pediatrics specifically recommends avoiding it on playgrounds. The manufacturers and vendors of these products claim that the silica stays inside the plastic coating.  However, sunlight and the grinding force from playing on the field breaks down the plastic coating. For that reason, even the product warranty admits that only 70% of the silica will remain encapsulated. The other 30% can be very harmful as children are exposed to it in the air.

In addition, the Envirofill pellets have been coated with an antibacterial called triclosan.  Triclosan is registered as a pesticide with the EPA and the FDA has banned triclosan from soaps because manufacturers were not able to prove that it is safe for long-term use.  Research shows a link to liver and inhalation toxicity and hormone disruption.  The manufacturer of Envirofill says that the company no longer uses triclosan, but they provide no scientific evidence that the antibacterial they are now using is any safer than triclosan.  Microscopic particles of this synthetic turf infill will be inhaled by children, and visible and invisible particles come off of the field, ending up in shoes, socks, pockets, and hair.

In response to the concerns of educated parents and government officials, other new materials are now being used instead of tire crumb and other very controversial materials.  However, all the materials being used (such as volcanic ash, corn husks, and Corkonut) have raised concerns and none are proven to be as safe or effective as well-designed grass fields.

Conclusions

There have never been any safety tests required prior to sale that prove that any artificial turf products are safe for children who play on them regularly.  In many cases, the materials used are not publicly disclosed, making independent research difficult to conduct.  None of these products are proven to be as safe as natural grass in well-constructed fields.

I have cited several relevant scientific articles on artificial turf in this letter, and there are numerous studies and growing evidence of the harm caused by these synthetic materials.  I would be happy to provide additional information upon request (dz@center4research.org).

I am not paid to write this statement.  I am one of the many parents and scientists who are very concerned about the impact of artificial fields on our children.  Your decisions about artificial turf and playground materials will directly and indirectly help educate parents throughout the state, making it even more important that your decision is based on scientific evidence, not on sales pitches by individuals with conflicts of interest.

Officials in communities all over the country have been misled by artificial turf salespeople. They were erroneously told that these products are safe.  But on the contrary, there is clear scientific evidence that these materials are harmful.  The only question is how much exposure is likely to be harmful to which children?  We should not be willing to take such a risk.  Our children deserve better.

Please pass HB 1098 and thank you for addressing this critical public health issue.

CPTF’s Comments on Cyramza for Metastatic Lung Cancer at FDA Oncologic Drugs Advisory Committee Meeting

Cancer Prevention and Treatment Fund: February 26, 2020

Cancer Prevention and Treatment Fund’s Public Comments on Cyramza for Metastatic Lung Cancer at FDA Oncologic Drugs Advisory Committee Meeting

Thank you for the opportunity to share our views today. The Cancer Prevention and Treatment Fund understands the need for effective new treatments for metastatic lung cancer. However, the data provided by the sponsor does not provide evidence that Cyramza improves survival, and it may worsen quality of life.

Although there are not yet enough long-term data to determine how Cyramza affects patients’ survival, the data that are available are not promising. Survival rates are almost identical with the drug or placebo (HR 0.92). It is important to note that the survival rates were never significantly different, but the difference was smaller as longer-term data were analyzed. We agree with the FDA that based on the confidence intervals, the drug could potentially worsen survival by about 30% — or could possibly improve survival by 30%. That risk of shortening overall survival is especially important because of the other risks of the treatment.

Let’s look at the number of deaths that occurred within 30 days of treatment in the RELAY trial. Of the 221 patients taking Cyramza, 6 died from adverse events, compared to none in the placebo arm. FDA specified that one of these was caused by drug treatment, while a second may have been caused by the drug. Although the FDA agrees with Lilly’s assessment that the other deaths are not caused by the drug or drug combination, those data aren’t made available so we can’t draw conclusions. But even if it is only 2 deaths, that’s almost 1% of the patients – not an irrelevant number! Since this shows that Cyramza can be fatal for these patients, and there is no currently no evidence that it significantly increases overall survival on average for lung cancer patients, the FDA expressed a great deal of concern about this indication. If Cyramza benefits any specific types of patients in terms of overall survival, there is no evidence of who those patients are likely to be.

Patients treated with Cyramza had a 7 month improvement in progression-free survival. This may be meaningful to patients if it is also associated with an improvement in quality of life. However, the data from the RELAY trial do not support this.  The sponsor spins these results to conclude that the quality of life of life is not worse in patients taking Cyramza, but in fact, patients in the placebo group had fewer symptoms, such as shortness of breath, pain, and daily activity level, as measured by the Lung Cancer Symptom Scale. Our Center has worked with many seriously ill patients over the years, and we’ve found that
patients care about two outcomes: 1) will they live longer and 2) what will their quality of life be in the days, weeks, months, or years they have left. The only patients that care about progression free survival are the ones that don’t understand what it means. When patients are told a drug is promising based on progression free survival, it is confusing and frankly misleading to most patients. They think it means they will live longer.

The results of the research are also worrisome regarding the FDA’s measures of specific adverse events. 72% of patients treated with Cyramza experienced a grade 3 or higher adverse events compared to only 54% of patients treated with placebo.

  • 29% of patients treated with Cyramza experienced a serious adverse event compared to 21% of placebo-treated patients.
  • Bleeding and hemorrhage occurred twice as often in patients treated with Cyramza,
    compared with placebo.
  • Grade 3 hypertension was roughly 5x more common among those treated with Cyramza compared with placebo. Overall hypertension was roughly 4x as prevalent among the Cyramza group.  I disagree with the sponsor’s assertion that hypertension is no big deal. In fact, heart disease is the #1 killer of men and women in the U.S. and hypertension is called “the silent killer.” Yes, there are medications for it, but they also have side effects that can be debilitating.

Overall, the study’s results suggest that when Cyramza is combined with erlotinib and compared with placebo plus erlotinib, the potential benefits of Cyramza do not outweigh the known risks. Given the data provided, there is no justification for rushing to approve this particular treatment.

We respectfully request that you advise FDA to not approve this indication for Cyramza without evidence that it improves overall survival enough to outweigh the risk for adverse events and reduced quality of life.

After FDA’s Cancer Director Dr. Richard Pazdur instructed the Advisory Committee at length that progression free survival was acceptable evidence for approval even if there was no evidence of overall survival, and even if more effective treatments were already available, the Advisory Committee voted 6 in favor of approval and 5 opposed.

Drugs to Quit Smoking Can Affect Mental and Physical Health: the Truth About Chantix and Zyban

Uncategorized,

Everyone knows that smoking harms health and that the habit is difficult to quit. Unfortunately, some products that help people stop smoking can also be harmful – perhaps too harmful to consider using.

In June 2011, the U.S. Food and Drug Administration (FDA) announced new concerns about the safety of Chantix. Their announcement came in the months after two reports by independent researchers that there were more reports of deaths and violence from taking Chantix than any other drug.[1]

These reports added to concerns about two stop-smoking drugs, Chantix and Zyban. In July 2009, the FDA had already announced “black box” warning labels on both drugs. A “black box” warning is the FDA’s most serious caution and indicates that a drug carries significant health risks.  The black box warnings for Chantix and Zyban warn of the mental health risks associated with their use, which can include changes in behavior, depressed mood, hostility, and suicidal thoughts.[2]

These warnings were recommended as the result of information gathered from clinical trials, as well as a series of reports to the FDA’s Adverse Event Reporting System. Zheng-Xiong Xi, MD, PhD, a researcher at the National Institute on Drug Abuse, found that Chantix was associated with incredibly dangerous side effects in many individuals, including suicide attempts and seizures, as well as psychosis, depression, and serious injuries resulting from dizziness, loss of consciousness, movement disorders, and visual disturbances.These problems have been noted among individuals with a history of mental illness but also have occurred among individuals with no prior history of mental illness.[3]

Analysis from reports to the FDA’s Adverse Event Reporting System similarly shows that some people who used Chantix and Zyban began experiencing changes in behavior, depressed mood, and suicidal thoughts shortly after starting the medication. The symptoms usually ended shortly after the medication was stopped, but some people still reported symptoms after stopping the medications, while still others did not even begin developing the symptoms until after they stopped taking the drug.

Neither Chantix nor Zyban contains nicotine, unlike other smoking cessation aids such as chewing gum and the patch. Nicotine withdrawal can also cause mental health problems similar to those caused by Chantix and Zyban, such as depression, anxiety, irritability, restlessness, and sleep disturbance. However, the mental health risks of these two drugs far exceed the symptoms suffered by people with nicotine withdrawal.

Zyban is another name for Wellbutrin, an anti-depressant. Its marketing as a smoking-cessation drug came about after researchers noticed that smokers who took Wellbutrin for depression had less desire to smoke. GlaxoSmithKline carried out additional research in order to get approval to sell Wellbutrin under a different name as a medication to quit smoking. However, like most anti-depressants, the pills–whether they are called Wellbutrin or Zyban–can cause an increase in suicidal thoughts.  Antidepressants have carried black box warnings about suicide risks since 2004.

Chantix: News about increased risk of suicide, violent behavior, and other mental health problems

From the approval of Chantix in May 2006 until July 2009, the drug was linked to reports of approximately 100 suicides, 200 suicide attempts, and almost 5,000 serious psychiatric events. Doctors are not required to report deaths or serious complications to the companies that make the medication or the FDA, although drug companies are required to do so.  Because most doctors don’t report, it is assumed that the numbers are much higher and that those problems have continued since 2009.  In fact, in May 2011, the Institute for Safe Medication Practices (ISMP) revealed that hundreds of cases of suicides, psychotic reactions, hostility, aggression and other serious problems tied to Chantix had not been properly reported to the FDA by Pfizer, the drug’s manufacturer. Among the 589 delayed reports of severe problems, there were more than 150 suicides-almost doubling those previously known.  Thomas J. Moore, the ISMP senior scientist who analyzed the data, stated that, based on the FDA’s adverse event reports, Chantix is the riskiest of all drugs sold in the U.S. In the third quarter of 2010, it ranked first in reported deaths, with twice as many fatalities recorded as any other drug.[1]

The discovered reports coincide with a study by Moore released in December 2010 examining all of the most serious adverse drug events reported to the FDA since 1968. Chantix had the largest number of reported cases of violence (408).[1]

A large 2011 study found that Chantix was 8.4 times more likely to lead to suicide or self-injury compared to nicotine replacement products like nicotine gum or patches. There were 1,818 reported cases of suicidal thoughts or behavior for Chantix and only 50 for nicotine replacement products.[4]

Increased risk of heart attack for patients with cardiovascular disease

Research has shown that these stop-smoking drugs affect not only mental health, but can also jeopardize physical health. In June 2011, the FDA warned that Chantix may be associated with an increased risk of certain cardiovascular adverse events in patients who have cardiovascular disease. After reviewing a randomized clinical trial of 700 smokers with stable cardiovascular disease, the FDA found that certain events, including heart attacks, were reported more frequently in patients treated with Chantix than in patients treated with placebo (2.0% vs. 0.9%).[5]

Do the risks outweigh the benefits? NCHR says YES

Quitting smoking is usually a step towards improving one’s health, but doing so at the risk of mental or heart health is not a good compromise.  Instead, there are other, safer ways to quit smoking.

The unreported deaths and serious injuries for people taking Chantix raises questions about whether other information is being withheld. Since most doctors don’t report adverse reactions to the FDA, it is likely that Chantix has caused many more deaths and injuries than reported. For that reason, we believe that Chantix is not a safe choice. At the very least, the mental health of anyone taking Chantix or Zyban should be closely monitored by a healthcare professional. Additionally, if you have a history of cardiovascular disease, consult your doctor before taking Chantix, and if you experience new or worsening symptoms of cardiovascular disease, contact your doctor immediately.

If you or someone you know is trying to quit smoking, be aware of the symptoms associated with quitting, and if symptoms develop, a healthcare professional should be consulted.

Controversy Over Black Box Warning

In 2014, the makers of Chantix lobbied the FDA to remove the black box warning on the drug, citing a meta-analysis, an observational study of hospital records, and reported adverse events to argue that dangerous side-effects were not as common as previously believed. However, we question the results of the meta-analysis, since many studies on Chantix were excluded.

Meta-analysis is a valuable tool, but its accuracy depends on the quality of each study and whether they fit together. The five studies included in the meta-analysis consisted of one study of schizophrenics, one study of depressed patients, and 3 studies of mentally healthy patients. It is important to study schizophrenics and depressed patients, but those data should not be analyzed together with 3 studies that exclude such patients.

To consider the implications of studies that claim to show that Chantix does not have serious psychiatric side effects, it is important to realize that most people with acute psychiatric side effect from medication do not end up in hospitals or the ER. Psychiatric side effects are often not reported in medical records. Because psychiatric commitment laws depend on acts of violence, not threats of violence, many people with dramatic psychiatric symptoms end up in jail, not in hospitals. In fact, some studies show that there are more mentally ill individuals in the criminal justice system than in psychiatric facilities.

Removal of Black Box Warning

After hearing the testimony about these shortcomings from NCHR President Diana Zuckerman and numerous other experts, the FDA decided to keep the black box warning on Chantix in 2015. However, in response to industry pressure, the FDA removed the black box in 2016[6], and the warnings that were in the black box are now part of the label under a heading of “Warnings and Precautions” for both Chantix and Zyban.[7, 8] Thus, although the official black box warning for Chantix has been removed, there are still warnings on their labels about the psychiatric risks of Chantix and Zyban. In addition to the label, which most patients do not read, the Medication Guide listed on the Chantix manufacturer’s website warns of the potential side effects of “New or worse mental health problems, such as changes in behavior or thinking, aggression, hostility, agitation, depressed mood, or suicidal thoughts or actions.”[9] These warnings are also on the home page of Chantix.com. Zyban has a black box warning about suicidal thoughts, and warnings similar to Chantix on the label and medication guide.

Below are the current “Warnings and Precautions” listed for Chantix and Zyban:

Neuropsychiatric Adverse Events: Postmarketing reports of serious or clinically significant neuropsychiatric adverse events have included changes in mood (including depression and mania), psychosis, hallucinations, paranoia, delusions, homicidal ideation, aggression, hostility, agitation, anxiety, and panic, as well as suicidal ideation, suicide attempt, and completed suicide. Observe patients attempting to quit smoking with CHANTIX for the occurrence of such symptoms and instruct them to discontinue CHANTIX and contact a healthcare provider if they experience such adverse events.

Neuropsychiatric adverse events: Postmarketing reports of serious or clinically significant neuropsychiatric adverse events have included changes in mood (including depression and mania), psychosis, hallucinations, paranoia, delusions, homicidal ideation, aggression, hostility, agitation, anxiety, and panic, as well as suicidal ideation, suicide attempt, and completed suicide. Observe patients attempting to quit smoking with ZYBAN for the occurrence of such symptoms and instruct them to discontinue ZYBAN and contact a healthcare provider if they experience such adverse events

Below are the previous black box warnings for both Zyban and Chantix:

ZYBAN:

Serious neuropsychiatric reactions have occurred in patients taking ZYBAN for smoking cessation. The majority of these reactions occurred during bupropion treatment, but some occurred in the context of discontinuing treatment. In many cases, a causal relationship to bupropion treatment is not certain, because depressed mood may be a symptom of nicotine withdrawal. However, some of the cases occurred in patients taking ZYBAN who continued to smoke.

CHANTIX:

Some people have had changes in behavior, hostility, agitation, depressed mood, suicidal thoughts or actions while using CHANTIX to help them quit smoking. Some people had these symptoms when they began taking CHANTIX, and others developed them after several weeks of treatment or after stopping CHANTIX. If you, your family or caregiver notice agitation, hostility, depression or changes in behavior, thinking, or mood that are not typical for you, or you develop suicidal thoughts or actions, anxiety, panic, aggression, anger, mania, abnormal sensations, hallucinations, paranoia or confusion, stop taking CHANTIX and call your doctor right away. Also tell your doctor about any history of depression or other mental health problems before taking CHANTIX, as these symptoms may worsen while taking CHANTIX.

NCHR’s Testimony to FDA on TOOKAD to Treat Low-Risk Prostate Cancer

Prostate Cancer, Testimony & Briefings, ,

Diana Zuckerman, National Center for Health Research, February 26, 2020

Thank you for the opportunity to speak today.  I am Dr. Diana Zuckerman, president of the National Center for Health Research. Our center analyzes scientific and medical data to provide objective health information to patients, health professionals, and policy makers. We do not accept funding from drug or medical device companies, so I have no conflicts of interest.

Although active surveillance is recommended for many patients with low-risk prostate cancer, some patients prefer treatment and that can be a reasonable choice as long as the treatment has a meaningful benefit and does not increase patients’ harms. However, the clinical data for TOOKAD that we are discussing today do not clearly demonstrate that its benefits outweigh its risks – efficacy is uncertain, particularly for U.S. patients, and the drug has the well-known very negative side effects typical of prostate cancer treatments.  

There are 5 major problems with the data, and the FDA did an excellent job of expressing their concerns:

#1.  There was only 1 clinical trial. Replication is the key to science, and effective treatments are available for prostate cancer, so the FDA should not approve a new treatment based on just one study.

#2.  This one trial took place in Europe, and 99.8% of participants were white.  Five patients – not 5% but only 5 men — were not white. Given the higher percentage of African American men who die of prostate cancer, this lack of diversity should not be considered acceptable, unless the FDA is considering approving this product for white men only.

#3. The accuracy of detecting cancer is one major problem. The data showed a high false negative rate. 13.5% of those in the active surveillance arm had a negative biopsy after 2 years. Since it is unlikely that the cancer would spontaneously disappear, this probably reflects false positives in the original diagnosis or false negatives in the post-test. This high false negative rate raises major concerns about the accuracy of biopsies in the treatment arm and at baseline. 

#4. Further, there was a large amount of missing data regarding biopsies at 24 months. Unfortunately, 18.4% of the patients in the treatment arm and 41.5% of those in the active surveillance arm were missing these crucial pieces of information regarding efficacy.  That makes it impossible to draw conclusions based on this one study. 

 #5. The trial was open-label, meaning patients as well as those collecting the data knew whether a particular patient was receiving the treatment or active surveillance. The decision to pursue definitive therapy  — such as surgery — was a subjective decision. Wouldn’t active surveillance patients be more likely to choose treatments later. Also, when biopsy results were uncertain, pathologists may have been biased by their knowledge of whether or not a patient was assigned to the treatment group. 

The FDA held a workshop in September 2018 to discuss issues related to clinical trials of novel treatments for localized prostate cancer.  They concluded that treatment endpoints might be clinically meaningful only if 1) the patients using the new therapy were less likely to undergo subsequent treatment (such as surgery), 2) there was an overall reduction in adverse events, and 3) there was no reduction in long-term cancer control.  However, in this trial, these criteria were not met. 95% of those treated with TOOKAD had adverse event in the weeks after treatment compared to 55% of the men on active surveillance. For many men these problems continued 2 years after treatment, when 34% continued to have urinary problems compared to 16% with active surveillance. Two years after treatment, 38% of patients treated with TOOKAD had erectile dysfunction, compared with 12% of those assigned to active surveillance. In other words, erectile dysfunction was 3x as prevalent among those treated with TOOKAD.

The long-term complications of the treatment that are unclear.  In addition to the urinary problems and ED that might be worse for those who are subsequently treated with surgery, it may be more difficult to obtain accurate biopsies. 

The American Urological Association recommends active surveillance as the best available treatment for low-risk prostate cancer patients, and the data clearly support that recommendation.  We understand that the fear of cancer can persuade men to seek treatment, but if so they should not be bamboozled by ads to choose a product that may have no benefits for them but that does have clear risks of erectile dysfunction and urinary problems. If the FDA thinks this product might have a useful benefit, they should require at least one double-blind study – preferably two – since the treatment does not involved surgery and is therefore easier to blind.  The studies should also include a patient population that represents the diversity of men with prostate cancer. There is no need to rush to approve this particular treatment based on a single, open label trial with endpoints of questionable clinical relevance and problems with inaccurate diagnoses. Better research needs to be completed before approval because the sponsor did not comply with FDA’s recommendations for the study and was even less likely to do so after the product is approved.   

The Oncologic Drugs Advisory Committee voted 13 to 2 against approval of TOOKAD to treat low-risk prostate cancer.

NCHR’s Comments on FDA’s Notice on the Modified Risk Tobacco Product Applications for IQOS System With Marlboro Heatsticks

Policy, , , , ,

National Center for Health Research, February 24, 2020

National Center for Health Research’s Public Comments on FDA’s Notice on the Modified Risk Tobacco Product Applications  for IQOS System With Marlboro Heatsticks

Thank you for the opportunity to comment on the FDA Notice on the Modified Risk Tobacco Product Applications for IQOS System With Marlboro Heatsticks, Marlboro Smooth Menthol Heatsticks, and Marlboro Fresh Menthol Heatsticks submitted by Philip Morris International.

The National Center for Health Research (NCHR) is a nonprofit think tank that conducts, analyzes, and scrutinizes research, policies, and programs on a range of issues related to health and safety. We do not accept funding from companies that make products that are the subject of our work.

We strongly oppose the approval of this modified risk application by Philip Morris International. According to the FDA, a modified risk tobacco product needs to demonstrate that it (1) significantly reduces harm to smokers and (2) promotes public health. However, there is insufficient evidence to support the claim that these products significantly reduce harm for smokers. Further, there are potential risks to public health because these products may be appealing to non-smokers, particularly adolescents.The products do contain nicotine, which is addictive.

The applicant claims that “switching completely from cigarettes to the IQOS system can reduce the risks of tobacco-related diseases.” They also claim that it delivers tobacco taste and nicotine satisfaction, which could promote IQOS use as an alternative to smoking cigarettes. However, there is not sufficient data that cigarette smokers would switch to complete IQOS use instead of continuing to smoke traditional cigarettes and thus engage in dual use. The study designs, for example, do not show that consumers’ actual use of the product would significantly reduce the use of traditional cigarettes or result in them switching completely from cigarette use. Without that scientific evidence, there is no proof to support the applicant’s claim that this product leads to a substantial reduction in toxicity.

Nearly 90% of smokers smoked their first cigarette before the age of 18,1 yet adolescents were not included in any of the studies provided by the applicant. The vaping epidemic among adolescents illustrates why we should be concerned about lack of data on teenagers. Research has shown that over half of 12th graders who vape reported that they do so “in order to “see what it’s like,” and one-third report that they vape “because it tastes good.”2 The interest that adolescents show in vaping suggest that adolescents who previously did not consume tobacco products may be interested in trying a novel form of smoking, particularly one with a flavor, such as menthol. Since the applicant has failed to provide any research on the likely impact on adolescents, we can’t assume that adolescents would not be enticed to try the product.

The main reason why we oppose a risk mitigation claim for these products is that they have not been proven to reduce risk. In addition, previous studies have demonstrated that adolescents are likely to perceive products with risk-mitigation claims as less harmful, and Philip Morris International has failed to demonstrate that this would not be the case for their IQOS system. To add to the public health concerns, the effects of the risk mitigation claims in advertising and marketing were not tested, despite the fact that some tobacco advertisements can increase use among youth. The increase in vaping among youth has demonstrated that adolescents are swayed by advertising, and that once they begin a habit such as vaping or smoking, they are unlikely to stop.

In summary, the data provided do not adequately support the claim that the IQOS systems 1) significantly reduce harm for smokers and 2) promote public health. A modified risk statement may encourage people, particularly adolescents, who do not smoke to begin using this tobacco product. At the same time, such a statement could lead to more dual usage among current smokers thinking that this is a safe alternative.

National Center for Health Research Written Statement to Greenwich Board of Education

Testimony & Briefings, ,

National Center for Health Research, February 19, 2020

Written Statement to Greenwich Board of Education

Diana Zuckerman, PhD, National Center for Health Research

February 19, 2020

Dear Chairman Bernstein and Members of the Greenwich Board of Education:

I am disappointed that I was unable to be there in person for your meeting on February 20, but I wanted to update you on the latest research about the health risks of artificial turf for children and adults.

As President of the National Center for Health Research, I want to share the information we have provided to Members of Congress, state and federal agencies, state and local legislators, parents, and others who want to ensure that our children are not exposed to dangerous chemicals or metals when they play on artificial turf or playgrounds. Our nonprofit think tank is located in Washington, D.C. Our scientists, physicians, and health experts conduct studies and scrutinize research. Our goal is to explain scientific and medical information that can be used to improve policies, programs, services, and products.

We commend you for considering the possible risks of replacing grass fields with artificial turf. In the last year, we’ve learned new information about lead and PFAS in artificial turf, as well as the risks of some of the newer infill materials that turf companies are using to replace tire crumb. Tire crumb has well-known risks, containing chemicals that have the potential to increase obesity; contribute to early puberty; cause attention problems such as ADHD; exacerbate asthma; and eventually cause cancer. However, the plastic grass itself has dangerous levels of lead, PFAS, and other toxic chemicals as well.  PFAS are of particular concern because they are “forever chemicals” that get into the human body and are not metabolized, accumulating over the years. Replacing tire waste with silica, zeolite, and other materials also has substantial risks.

Federal agencies such as the EPA and the U.S. Consumer Product Safety Commission have been investigating the safety of these products. Despite claims to the contrary, none have concluded that artificial turf is safe. Although the Trump Administration’s EPA stated that there was no conclusive evidence that the levels of chemicals in artificial turf was harmful to children, they made it clear that their research was based on assumptions rather than scientific research on children.

Lead

As you know, the American Academy of Pediatrics states that no level of lead exposure should be considered safe for children, because lead can cause cognitive damage even at low levels. Some children are more vulnerable than others, and that can be difficult or even impossible to predict. Since lead has been found in tire crumb as well as new synthetic rubber, it is not surprising that numerous artificial turf fields and playgrounds made with either tire crumb or “virgin” rubber have been found to contain lead. However, the Centers for Disease Control and Prevention (CDC) also warns that the “plastic grass” made with nylon or some other materials also contain lead. Whether from infill or from plastic grass, the lead doesn’t just stay on the surface. With wear, the turf materials turn to dust that is invisible to the eye but that children are breathing in when they play.

Why are chemicals that are banned from children’s toys allowed in artificial turf and rubber playground surfaces?

Synthetic rubber and plastic are made with different types of endocrine (hormone) disrupting chemicals (also called EDCs). There is very good evidence regarding these chemicals in tire crumb, based on studies done at Yale and by the California Office of Environmental Health Hazard Assessment (OEHHA).[1]

A 2018 report by Yale scientists detected 92 chemicals in samples from 6 different artificial turf companies, including unused bags of tire crumb. Unfortunately, the health risks of most of these chemicals had never been studied. However, 20% of the chemicals that had been tested are classified as probable carcinogens and 40% are irritants that can cause asthma or other breathing problems, or can irritate skin or eyes.[2]

There are numerous studies indicating that endocrine-disrupting chemicals found in rubber and plastic cause serious health problems. Scientists at the National Institute of Environmental Health Sciences (which is part of NIH) have concluded that unlike most other chemicals, hormone-disrupting chemicals can be dangerous at very low levels, and the exposures can also be dangerous when they combine with other exposures in our environment. 

That is why the Consumer Product Safety Commission has banned numerous endocrine-disrupting chemicals from toys and products used by children. The products involved, such as pacifiers and teething toys, are banned even though they would result in very short-term exposures compared to artificial turf or playground surfaces.

A report warning about possible harm to people who are exposed to rubber and other hormone disrupting chemicals at work explains that these chemicals “can mimic or block hormones and disrupt the body’s normal function, resulting in the potential for numerous health effects. Similar to hormones, EDC can function at very low doses in a tissue-specific manner and may exert non-traditional dose–response because of the complicated dynamics of hormone receptor occupancy and saturation.”[3]

Studies are beginning to demonstrate the contribution of skin exposure to the development of respiratory sensitization and altered pulmonary function. Not only does skin exposure have the potential to contribute to total body burden of a chemical, but also the skin is a highly biologically active organ capable of chemical metabolism and the initiation of a cascade of immunological events, potentially leading to adverse outcomes in other organ systems.

Scientific Evidence of Cancer and Other Systemic Harm

It is essential to distinguish between evidence of harm and evidence of safety. Like the Trump Administration’s EPA, companies that sell and install artificial turf often claim there is “no evidence children are harmed” or “no evidence that the fields cause cancer.” This is often misunderstood as meaning the products are safe or are proven to not cause harm. Neither is true.

It is true that there no clear evidence that an artificial turf field has caused specific children to develop cancer. However, the statement is misleading because it is virtually impossible to prove any chemical exposure causes one specific individual to develop cancer.

As an epidemiologist, I can also tell you that for decades there was no evidence that smoking or Agent Orange caused cancer. It took many years to develop that evidence, and the same will be true for artificial turf. 

I have testified about the risks of these materials at the U.S. Consumer Product Safety Commission as well as state legislatures and city councils. I am sorry to say that I have repeatedly seen and heard scientists paid by the turf industry and other turf industry lobbyists say things that are absolutely false. They claim that these products are proven safe (not true) and that federal agencies have stated there are no health risks (also not true). 

However, we know that the materials being used in artificial turf and rubber playground surfaces contain carcinogens, and when children are exposed to those carcinogens day after day, week after week, and year after year, they increase the chances of our children developing cancer, either in the next few years or later as adults. That should be adequate reason not to install them in your community. That’s why I have spoken out about the risks of artificial turf in my community and on a national level. The question must be asked: if they had all the facts, would Greenwich or any other community choose to spend millions of dollars on fields that are less safe than well-designed natural grass fields?

Dangerously Hot and Hard Fields

I lived in Connecticut for several years while on the faculty at Yale and Vassar, and I know the climate well. When the weather is warm and/or sunny, it is usually quite pleasant to be outside – as long as you aren’t on artificial turf or an outdoor rubber surface. Even when the temperature above the grass is 80 degrees Fahrenheit, artificial turf can reach 150 degrees or higher. Obviously, a 90 degree day is likely to be even hotter than 150 degrees on turf. That can cause “heat poisoning” as well as burns.

Artificial turf fields get hard as well. Turf companies recommend annual tests at 10 locations on each turf field, using something called a Gmax scores. A Gmax score over 200 is considered extremely dangerous and is considered by industry to pose a death risk. However, the synthetic turf industry and ASTM (American Society for Testing and Materials), suggest scores should be even lower — below 165 to ensure safety comparable to a grass field. Is Greenwich paying to have these tests conducted on all your public artificial turf fields?

The hardness of natural grass fields is substantially influenced by rain and other weather; if the field gets hard, rain or watering will make it safe again. In contrast, once an artificial turf field has a Gmax score above 165, it needs to be replaced because while the scores can vary somewhat due to weather, the scores will inevitably get higher because the turf will get harder. Gmax testing involves testing 10 different areas of a playing fields, to make sure all are considered safe.  Some officials average those 10 scores to determine safety; however, experts explain that is not appropriate. If a child (or adult) falls, it can be at the hardest part of the field, which is why that is the way safety is determined.

Environmental Issues

In addition to the health risks to school children and athletes, approximately three tons of infill materials migrate off of each synthetic turf field into the greater environment each year. About 2-5 metric tons of infill must be replaced every year for each field, meaning that tons of the infill have migrated off the field into grass, water, and our homes.[4] The fields also continuously shed microplastics as the plastic blades break down.[5,6] These materials may contain additives such as PAHs, flame retardants, UV inhibitors, etc., which can be toxic to marine and aquatic life; and microplastics are known to migrate into the oceans, food chain, and drinking water and can absorb and concentrate other toxins from the environment.[7,8,9]

Synthetic surfaces also create heat islands.10,11 In contrast, organically managed natural grass saves energy by dissipating heat, cooling the air, and reducing energy to cool nearby buildings. Natural grass and soil protect groundwater quality, biodegrade polluting chemicals and bacteria, reduce surface water runoff, and abate noise and reduce glare.[12]

Envirofill and Alternative Infills

Envirofill artificial turf fields are advertised as “cooler” and “safer,” but our research indicates that these fields are still at least 30-50 degrees hotter than natural grass. Envirofill is composed of materials resembling plastic polymer pellets (similar in appearance to tic tacs) with silica inside. Silica is classified as a hazardous material according to OSHA regulations, and the American Academy of Pediatrics specifically recommends avoiding it on playgrounds. The manufacturers and vendors of these products claim that the silica stays inside the plastic coating. However, sunlight and the grinding force from playing on the field breaks down the plastic coating. For that reason, even the product warranty admits that only 70% of the silica will remain encapsulated. The other 30% can be very harmful as children are exposed to it in the air. 

In addition, the Envirofill pellets have been coated with an antibacterial called triclosan. Triclosan is registered as a pesticide with the EPA and the FDA has banned triclosan from soaps because manufacturers were not able to prove that it is safe for long-term use. Research shows a link to liver and inhalation toxicity and hormone disruption. The manufacturer of Envirofill says that the company no longer uses triclosan, but they provide no scientific evidence that the antibacterial they are now using is any safer than triclosan. Microscopic particles of this synthetic turf infill will be inhaled by children, and visible and invisible particles come off of the field, ending up in shoes, socks, pockets, and hair.

In response to the concerns of educated parents and government officials, other new materials are now being used instead of tire crumb and other very controversial materials. However, all the materials being used (such as volcanic ash, corn husks, and Corkonut) have raised concerns and none are proven to be as safe or effective as well-designed grass fields. 

Conclusions

There have never been any safety tests required prior to sale that prove that any artificial turf products are safe for children who play on them regularly. In many cases, the materials used are not publicly disclosed, making independent research difficult to conduct. None of these products are proven to be as safe as natural grass in well-constructed fields. 

I have cited several relevant scientific articles on artificial turf in this letter, and there are numerous studies and growing evidence of the harm caused by these synthetic materials. I would be happy to provide additional information upon request (dz@center4research.org).

I am not paid to write this statement. I am one of the many parents and scientists who are very concerned about the impact of artificial fields on our children. Last year, I told members of the BET that their decision about artificial turf can save lives and improve the health of children in Greenwich.  You owe it to your community to make sure you know the risks of artificial turf and do all you can to protect Greenwich children from the known risks and also the suspected risks.  Because of Greenwich’s reputation as a well-educated and affluent community, your decisions about artificial turf in Greenwich will be cited by other communities, making it even more important that your decision is based on scientific evidence, not on sales pitches by individuals with conflicts of interest.

Officials in communities all over the country have been misled by artificial turf salespeople. They were erroneously told that these products are safe. But on the contrary, there is clear scientific evidence that these materials are harmful. The only question is how much exposure is likely to be harmful to which children? We should not be willing to take such a risk. Our children deserve better.

Sincerely,

Diana Zuckerman, Ph.D.

President

NCHR Testimony on Low Nicotine Cigarette Claim

Testimony & Briefings, , ,

Nina Zeldes, National Center for Health Research, February 14, 2020

Thank you for the opportunity to speak here today. My name is Dr. Nina Zeldes and I am here as a senior fellow speaking on behalf of the National Center for Health Research. Our research center analyzes scientific and medical data and provides objective health information to patients, providers and policy makers. We do not accept funding from drug and medical device companies or tobacco companies, so I have no conflicts of interest.

We strongly oppose the approval of this modified risk application by the 22nd Century Group for their low-nicotine combusted filtered cigarette tobacco products. According to the FDA, a modified risk tobacco product needs to demonstrate that it (1) significantly reduces harm to smokers and (2) promotes public health. Unfortunately, evidence is lacking to support the claim that this product significantly reduces harm for smokers. At the same time, it is likely to entice people who have never smoked, especially adolescents, to start smoking.

As the applicant has pointed out, this low nicotine cigarette poses similar risks of tobacco-related disease as conventional cigarettes. Its only advantage is that it contains much less nicotine, and could therefore be less addictive. However, the claims of reduced harm seem to be based entirely on the assumption that people would smoke less often – an assumption that was not adequately supported by the applicant’s data. For example, this product was rated as less satisfying than smokers’ usual brand of cigarettes and less likely to be used again compared to nicotine gum, raising questions about whether smokers would switch completely to this product and ultimately quit smoking.

The FDA briefing document points out that nicotine is often perceived as causing smoking-related health risks. That means that a claim of a product having “95% less nicotine” will be misunderstood as being less likely to cause cancer, when in fact it just means potentially less addictive. Although the applicant provided a voluntary warning that “less nicotine does NOT mean safer”, study participants who were shown this warning still perceived this product as safer than conventional cigarettes. Additionally, the applicant only tested the claims on packaging and not how they would be used in ads and social media. We’ve all learned that the context and imagery in these ads can vastly alter how these claims are interpreted. Tobacco companies have learned how to make very persuasive ads that go beyond the specific claims that they make.

And as we all know, smoking is a habit that is very difficult to break, and addiction to nicotine is only one of the reasons that quitting is so difficult.

Most smokers start smoking as children and adolescents, and yet adolescents were not included in any of the studies provided by the applicant. Previous studies have demonstrated that this group is likely to perceive products with a risk-mitigation claim as less harmful, but that is not proven in this case.

In conclusion, while the claim that this product contains 95% less nicotine may be factually correct, the company’s claims of health benefits are based on the implied assumption that this product would help smokers quit. If that is supposed to be the benefit, their product should have sought to market this product as a cessation aid. Moreover, the packaging does not explain how to achieve this health benefit. Because of such claims, smokers interested in reducing smoking-related health risks might start using this product, instead of quitting or using available FDA-approved cessation products. Meanwhile, non-smokers, particularly adolescents, might start using this product, thinking it is a safe alternative to other tobacco products.

If we’ve learned anything from the vaping epidemic, it is that adolescents are easy to influence, and once they start a habit like smoking or vaping, they are unlikely to stop. We encourage you to let the FDA know that you do not believe that would be an acceptable outcome.

Thank you.

FDA considers black box warning for all breast implants

Breast Cancer, In the News, News Stories & Editorials, We're In the News, , ,

Mariel Carbone, WCPO Cincinnati: February 09, 2020

Although many other survivors choose implants after their mastectomies, [Lily McBreen is] adamant that she won’t. Having almost lost her life once, she’s worried the side effects of receiving breast implants could endanger it again.

[…]

“I wanted to avoid the rheumatological symptoms that have been out in the news for so many decades,” she said. “There has been so many accounts of women complaining of problems with them.”

Those symptoms, which women are calling “breast implant illness,” are among the many reasons the United States Food and Drug Administration could soon take extreme measures when it comes to educating the public about implants.

[…]

Currently, the black box warning exists only as a draft while the FDA continues to consider its implementation.

The draft warning outlines three main concerns.

First, “breast implants are not considered life time devices” and women may require more surgery if complications occur.

It also states that implants have been associated with BIA-ALCL.

[…]

Finally, it describes how some patients have reported a variety of symptoms, including “joint paint, muscle aches, confusion, chronic fatigue, autoimmune disease and others.”

The FDA is also proposing a patient decision checklist, which would include situations in which the device should not be used, considerations for a successful breast implant candidate, risks of surgery, the importance of using an appropriate physician, the risk of BIA-ALCL and other symptoms and discussion of other options.

Still, some have said these proposals don’t go far enough, including Diana Zuckerman who is President of the National Center for Health Research. The center initiated the Breast Implant Working Group, which is made up of six experts including patient advocates and plastic surgeons.

“The FDA’s draft Black Box warning is too vaguely worded on BIA-ALCL and breast implant illness, and includes jargon that will not be understood by all patients,” the working group said in a statement. “The FDA draft Black Box states that ‘breast implants have been associated with the development of a cancer of the immune system called breast implant-associated anaplastic large cell lymphoma (BIA-ALCL).’ Association implies correlation rather than causation. In fact, the evidence is clear that breast implants can cause BIA-ALCL.”

Coalition Letter Urging Support for the Reversing the Youth Tobacco Epidemic Act

Policy, Testimony & Briefings

U.S. House of Representatives
Washington, DC 20515

Dear Representative:

We are writing to express our strong support for H.R. 2339, the Reversing the Youth Tobacco Epidemic Act of 2019. This legislation will address the current youth e-cigarette epidemic that is undermining the progress made in reducing youth tobacco use.

Use of e-cigarettes by youth has escalated rapidly in recent years, placing a new generation at risk of nicotine addiction and tobacco use. Between 2017 and 2019, e-cigarette use more than doubled among high school students (from 11.7% to 27.5%) and tripled among middle school students (from 3.3% to 10.5%). More than 5.3 million middle and high school students used e-cigarettes in 2019, an alarming increase of more than 3 million in two years. Use of other tobacco products, including cigarettes, cigars and hookah, is also a serious problem. Tobacco use remains the leading preventable cause of death in the United States and is responsible for approximately $170 billion in health care costs each year.

The Reversing the Youth Tobacco Epidemic Act provides a much-needed response to this serious public health problem. Its prohibition on flavored tobacco products, including flavored e-cigarettes, flavored cigars, and menthol cigarettes, is needed to stop tobacco companies from targeting and addicting kids with enticing flavors, such as gummy bear and cotton candy. Flavors mask the harsh taste of tobacco and make it easier for kids to start to use a tobacco product and to become addicted.

The bill’s prohibition on flavored e-cigarettes is all the more important because the Administration’s recently released policy on flavored e-cigarettes will leave thousands of flavored e-liquids and devices on the market. Flavors are a key reason for widespread youth use of e-cigarettes. Ninety-seven percent of current youth e-cigarette users have used a flavored e-cigarette in the past month, and seven out of ten said they used e-cigarettes “because they come in flavors I like.”

The bill’s prohibition on menthol cigarettes, flavored cigars, and other flavored tobacco products will also help protect kids and public health. More than half of youth smokers – and seven in ten African American youth smokers – smoke menthol cigarettes. As a result of decades of pervasive tobacco industry marketing, 85 percent of African-American smokers smoke menthol cigarettes, and menthol is a likely contributor to the higher rates of tobacco-caused death and disease experienced by African Americans. A 2013 Food and Drug Administration (FDA) analysis concluded that menthol cigarettes increase youth initiation, increase nicotine addiction, and make it harder for smokers to quit. Cigars are also available in a wide variety of flavors that make them more attractive to kids. More than one million high school students smoke cigars.

In addition to its prohibition on flavored tobacco products, the Reversing the Youth Tobacco Epidemic Act includes a number of other provisions that will help to reduce youth use of e-cigarettes and use of other tobacco products, including prohibiting online sales of most tobacco products, addressing inappropriate marketing and advertising, and ensuring that FDA will promptly implement the graphic health warnings on cigarette packs and advertising that are required under the 2009 Tobacco Control Act.

Youth use of e-cigarettes and other tobacco products is a problem that will not resolve itself. It will require action by Congress. The Reversing the Youth Tobacco Epidemic Act provides the comprehensive response that is needed. We urge you to support this important legislation when it comes to the House floor.
