Representatives, Committee on Government Reform
Hearing on Reduced Exposure/Reduced Risk Tobacco
Products: An Examination of the Potential Public Health Impact and Regulatory
Challenges
June 3, 2003
Thank you for the opportunity to testify on the issues and opportunities raised
by the diversity of nicotine delivery systems that have been marketed or are in
development. There are surely few other areas of health in which there are
actions that could be taken by the Congress and regulatory agencies that have
such great potential to either improve or harm public health. I will focus on
the questions posed in my invitation to testify.
Basis for Testimony
I am speaking on my own behalf and not as a representative of the
organizations, of which I am a member, consult for, or serve. I am Professor of
Behavioral Biology (Adjunct), Department of Psychiatry, The Johns Hopkins
University School of Medicine, and Vice President for Research and Health
Policy, Pinney Associates. I was trained in behavioral science, pharmacology,
and other disciplines relevant to understanding drug addiction and have focused
on tobacco-related issues for 25 years. From 1980 to 1996, I directed tobacco
and other drug research at the National Institute on Drug Abuse (NIDA). While at
NIDA, I was the primary liaison to the FDA on tobacco products and tobacco
addiction treatment. I contributed to numerous Surgeon General’s reports as
well as reports by other agencies. I am past president of the Society for
Research on Nicotine and Tobacco and have served on national and international
committees addressing the challenges posed by the plethora of nicotine delivery
systems that have been marketed or are possible. I presently serve on the World
Health Organization (WHO) Scientific Advisory Committee on Tobacco Product
Regulation. I am a recipient of a Robert Wood Johnson Foundation
Innovators Award and presently am director of this program which is intended to
recognize and foster innovations to reduce substance abuse and addiction in
America.
Fundamental facts
Tobacco addiction is the most pernicious and persistent of all forms
of drug addiction leading the majority of users to deadly daily use with 50% of
continuing smokers prematurely dying of smoking caused disease. Nonetheless,
with support and encouragement many tobacco users can achieve freedom from
tobacco and dramatically improve their chances of longer, healthier, and more
productive lives. Others need treatment to achieve these goals and increased
treatment access has helped millions of Americans quit smoking and other forms
of tobacco use.
Smoking cessation is accompanied by rapid and significant reductions
in risk of heart disease, as well as reduced risk of lung cancer and other
diseases over time. The earlier in life that lasting tobacco cessation is
achieved, the greater the benefits. Cessation also benefits non smokers,
children in particular, who suffer far higher rates of asthma, respiratory
infections, and sick days when they are exposed to smoke. In fact, when parents
quit smoking their children are half as likely to start smoking and twice as
likely to try to quit smoking if they have already begun. The lesson is clear:
adult cessation and youth prevention go hand in hand.
Comprehensive tobacco control efforts based on solid public health
principles reduce tobacco use and save lives. With increased education, tobacco
costs, restrictions on smoking, and access to treatment, more smokers are
quitting than ever before. On a parallel front, although youth tobacco use
remains unacceptably high, adolescent smoking and smokeless tobacco use has
steadily declined in the past 3-4 years. From a public health perspective these
trends are precious and encouraging, they spell improved health for millions of
Americans in the near term and in future generations. We must be very careful to
do nothing to reverse these trends.
Exposure reduction products could save lives or cost lives. What about
people who are unable to completely give up tobacco? Could we reduce their risk
of disease with products that are less poisonous? This was the premise of the
Federal Trade Commission (FTC) approach to encouraging the development and use
of reduced tar and nicotine cigarettes beginning in the 1960s. This was also the
implied premise of smokeless tobacco marketing to high school and college
athletes beginning in the 1970s. Of course motivation of FTC was to enable
disease reduction whereas the motivation of tobacco companies was to grow their
markets. Nonetheless, both experiments on the American people were health
disasters as documented in reports of the Surgeon General, the Institute of
Medicine, and National Cancer Institute. Both experiments went awry for decades
before independent researchers – not the companies that were marketing the
products – revealed the extent of the damage.
Light cigarettes delayed quitting and supposedly safer smokeless
tobacco was a magnet for athletes who had been considered at low risk for any
form of tobacco use prior to the healthy image product marketing of the 1970s.
This experience, although sobering, should not discourage our nation from making
progress on all fronts to reduce tobacco caused disease but it is a stark
reminder that unintended consequences are a mine field that should be negotiated
with supportive science and regulatory oversight. This is the core path
articulated in the 2000 Institute of Medicine report on the topic and this is
the core path that I support as a rational one towards improved health in
America.
The spectrum of nicotine delivery products – FDA regulation makes a
difference
Since 1985, nicotine gum has been available as an FDA approved smoking
cessation aid This product has been joined by a slowly increasing number of
additional forms of FDA approved Nicotine Replacement Therapy (NRT) products
including patch, nasal spray, oral inhaler, and lozenge. Each product differs in
form, dosing, side-effects, and instructions for smoking cessation. Determining
the conditions of safe and effective use and then overseeing labeling and
marketing to minimize unintended consequences such as situational use for the
purpose of avoiding smoking cessation, misuse by children, and providing special
guidance for youth, pregnant women, and persons with heart disease, is a science
guided process overseen by FDA.
In the vacuum of FDA regulation for non medicinal nicotine products, the 19th
century days of snake oil have re-emerged with vengeance since FDA was rebuked
by the Supreme Court in 2000. Correctly gauging FDA’s reluctance to act,
companies, big and small, have unleashed new products every 3-4 months with no
sign of letting up. These include the nicotine delivery devices “heated” by
carbon fuel and electronic ignition systems, a “Tic Tac”-like tobacco
lozenge”, and smokeless tobacco products marketed to help smokers remain
smokers by using slogans such as “Any Time Any Where”™ and for
“When You can’t smoke.”™ There are cigarettes implying safety with
claims of “reduced carcinogens”, “the next best thing to quitting,”
“80% less second hand smoke”, and one with a misleading claim of “nicotine
free” that is marketed for quitting by imitating the three step program of
nicotine patches. By internet, there are nicotine lollipops (complete with
“lollipop luggage”), nicotine water, and most recently, nicotine wafers.
Some of these products are placed next to FDA approved cessation aids in drug
stores and have websites amounting to virtual versions of the old horse drawn
patent medicine carts. None of these products have clinically tested and
approved protocols for dosing, guidance for use to achieve health benefits (even
where health benefits are implied) or guidance to minimize unintended
consequences or dangerous forms of use (such as dual use to perpetuate smoking).
Absent meaningful regulation, absent a science foundation, Americans are the
guinea pigs for these products.
Yet, it is theoretically possible that some of these products could be useful
to help people quit smoking. Some might be useful advances towards less deadly
tobacco products for those who are unable to quit tobacco altogether. Presently
there is no way for the consumer to know. There is no way for public health
officials to know. There is no way for Congress to know. Yet, there is a rather
straightforward path to this end. It is the path of scientific study and FDA
regulation built around the key principle or pre-market evaluation of the
products and the claims. It is a proven path towards products that are less
harmful and possibly even helpful.
Regulation can stifle or foster the treatment pipeline
FDA regulation of medications is the world’s premier model for pre-market
approval of safe and effective medicines, as well as maintaining safe and
usefully labeled food. Some of its most striking successes are the result of
flexible adaptation of its authorities to foster drug development such as
helping lead the world away from the view of AIDs as a death sentence to the
understanding that AIDs is increasingly a manageable disease.
One size does not fit all: Unfortunately with respect to tobacco
treatment products, the FDA approach has not kept pace with public demand or
potential treatment developments. Tobacco users want and need increasingly
flexible products to meet their diverse needs on the road to tobacco cessation.
Yet at present, all products are approved based on the same 6 week cessation
model that has served for nearly two decades, and the labeling has been
homogenized to the point that consumers and health professionals alike do not
understand how the different product forms may address differing needs. Worse,
overly harsh labeling results in ironies such as people removing patches so they
can “safely” smoke cigarettes.
So much more is possible. Medications could be used to reduce smoke
exposure on the road to complete cessation but FDA inflexibility has left such
applications on shelves. With support from the National Institute on Drug Abuse,
small developers have made great progress on “vaccine-like” long acting
medicines that could help former tobacco users remain tobacco free the rest of
their lives but this may require an entirely new model for evaluating efficacy.
One developer is even working on a nicotine water based cessation aid –
but there will be little incentive to properly evaluate it, develop clinically
tested guidance, and obtain FDA approval if people can already get an untested
version by Internet from a company that has dodged FDA oversight.
If FDA does not become more actively engaged and more flexible in the
application of its authorities to treatment development and approval, the most
innovative approaches will never see the light of day or will be so constrained
that they will be irrelevant to public health. Without lowering its standards
for safety and efficacy, FDA could give notice that it will consider application
of its fast track and expedited review authorities that have been so successful
in jumpstarting the pipeline of medicines for treating AIDS and cancer. FDA
could give notice that it will consider a broader range of science based
indications and claims shown to be desired and helpful to tobacco users. In
short, FDA has existing authorities that could unleash improvements in treatment
appeal, diversity, and availability. It just needs to apply them appropriately
and flexibly.
Federal efforts by CDC and NIH in particular have made a difference but
could do much more. It is in the interest of the federal government to
support greater access and appropriate use of treatments that are approved by
the FDA as well as those that are not under FDA jurisdiction but have been found
to be effective by the US Public Health Service, such as behavioral therapies
and alternative medications to meet the diversity of needs. Such treatments are
among the most cost-effective of all treatments in health care, especially when
compared to the enormous costs of treatments for the consequences of smoking
such as cancer chemotherapies.
More fundamentally, it is in the interest of striving toward a healthy and
productive America in which preventing unnecessary disease by tobacco is valued
as highly as preventing auto accidents, and bioterrorism. Remember the basic
numbers: 2000-3000 new tobacco users every day and more than 1000 preventable
tobacco deaths every day as far as the epidemiologic eye can see. Should freedom
from this preventable cause of death and disease be any less valued than freedom
from other causes of disease? Perhaps most important to consider is that this
area of public health is one in which many core principles have been
established, tested and found effective.
While we do not have all the answers, recent progress following the
application of tobacco control policies nationally and even more intensively in
states such as California and Massachusetts is more impressive than many of us
had dared hope for. A recent set of recommendations developed by the
Subcommittee on Cessation by the Interagency Committee on Smoking and Health
outlines a plan that is predicted to prevent at least three million premature
deaths in existing smokers, and help an additional five million Americans quit
smoking within one year. I support full adoption of the recommendations of this
special report to the Secretary Thompson. Furthermore, any progress towards the
goals articulated in the report would be steps in the right direction.
Tobacco products that genuinely reduce risk merit serious consideration
for inclusion in comprehensive tobacco control strategies but should be
positioned so as to not undermine approaches that work. I have served on
many committees in the US and for the World Health Organization that take
seriously the concept that every effort should be made to reduce tobacco toxin
exposures to those who continue to use tobacco. It is evident that tobacco
products are made more deadly than is technically and commercially feasible and
that performance standards could be developed to establish maximum allowable
levels of various toxins.
It is also recognized that effective regulation is critical. Without it, such
an approach could do more harm than good. This is because how a product is used
is as important how it is made when it comes to health effects. Regulation can
guide how it is made, marketed, and used and provide a mechanism for corrective
actions so that we never again need wait for several million deaths as we did
from light cigarettes before recognizing unintended consequences. Regulation of
tobacco and medications to treat dependence must be a coordinated process.
Otherwise we will perpetuate the situation in which snake oil is increasingly at
the doorstep in ever more attractive iterations, while proven safe and effective
treatments and strategies that could save lives die in development.
Dr. Koop’s advice: Be appropriate and flexible. In
conclusion, I urge the Committee to consider the wisdom of former Surgeon
General C. Everett Koop whose testimony in support of over the counter marketing
of nicotine gum and patches I paraphrase: It is easy to get the disease
and hard to get treatment, as a nation we must work to reverse this.
Over-the-counter marketing is a step in the right direction. Remarkably and
presciently, FDA granted this approval in the same year that it issued its rule
to regulate tobacco products and restrict tobacco product marketing. Time has
proved that FDA was on target from the perspective of science and health. We
need to get back on track. We need FDA to be appropriate and flexible; we need
it to be engaged. We need it to be supported by equally engaged CDC and NIH
efforts to provide the science and surveillance to assure that we are on the
path to better health in America.
Thank you for the opportunity to testify. I will be pleased to contribute to
this important process in any way.
