Of the 44.5 million adult smokers in the United States, 70 percent want to
quit and 40 percent make a serious quit attempt each year, but fewer than 5 percent
succeed in any given year. Effective tobacco cessation interventions are available
and could double or triple quit rates, but not enough smokers request or are
being offered these interventions. Nicotine is highly addictive and a major public
health concern. A national, coordinated strategy for tobacco control that casts
a wide net is needed to address this critical gap.
This was a key finding of an NIH state-of-the-science panel convened this week
to assess the available scientific evidence on tobacco use prevention, cessation,
and control. Full text of the panel's draft state-of-the-science statement will
be available later today at http://consensus.nih.gov, including the panel's identification
of promising directions for future research.
The panel found that smoking cessation interventions/treatments such as nicotine
replacement therapy, telephone quitlines, and counseling were individually effective,
and even more effective in combination. The panel also concluded that there is
strong evidence to support the effectiveness of economic strategies such as increasing
the cost of tobacco products through taxes and reducing out-of-pocket costs for
effective cessation therapies.
"It's important to recognize tobacco use as a serious, chronic health issue
that requires sustained attention," said David F. Ransohoff, M.D., professor
of medicine at the University of North Carolina at Chapel Hill and chair of the
conference panel. "Quitting is a struggle, but researchers have learned a lot
about what works to help people quit smoking. We need to make sure that effective
interventions reach the people who need them most."
The panel found that one way to increase the use of effective treatments would
be to better target interventions to address health disparities, recognizing
that generic treatments are not appropriate for everyone. ?To increase demand
for treatments we must motivate smokers to want them, expect them, and use them,? added
Ransohoff.
The panel emphasized that preventing initiation to tobacco use is essential
to reducing tobacco-related illness and death. Initiation to tobacco use occurs
primarily during adolescence, with almost all adult daily smokers trying cigarettes
before age 18. In fact, over 20 percent of 12th graders have smoked in the prior
30 days. The panel found that programs aimed at preventing tobacco use in youth
are most effective when they utilize multiple approaches such as mass media campaigns
and price increases through taxes on tobacco products.
The panel concluded that smokeless tobacco products were of great concern for
three reasons: 1) smokeless tobacco use is associated with numerous health risks,
2) there are limited data about the effect of smokeless tobacco on public health,
and 3) new products and aggressive marketing may increase use of smokeless tobacco
in the United States. The panel stressed that more research is needed to determine
the overall effect of marketing and use of these products.
The 14-member panel included experts in the fields of medicine, general and
pediatric psychiatry, addiction medicine, nursing, social work, population science,
cancer prevention, minority health and health disparities, clinical study methodology,
clinical epidemiology, and a public representative. A listing of the panel members
and their institutional affiliations is included in the draft conference statement.

In addition to the material presented at the conference by speakers and the
comments and concerns of conference participants presented during discussion
periods, the panel considered pertinent research from the published literature
and the results of a systematic review of the literature commissioned by the
NIH Office of Medical Applications of Research (OMAR). The systematic review
was prepared through the Agency for Healthcare Research and Quality (AHRQ) Evidence-based
Practice Centers (EPC) program, by the RTI International-University of North
Carolina Evidence-based Practice Center. The EPCs develop evidence reports and
technology assessments based on rigorous, comprehensive syntheses and analyses
of the scientific literature, emphasizing explicit and detailed documentation
of methods, rationale, and assumptions. The evidence report on Tobacco Use:
Prevention, Cessation, and Control is available at http://www.ahrq.gov/clinic/tp/tobusetp.htm.
The panel's statement is an independent report and is not a policy statement
of the NIH or the federal government. The NIH Consensus Development Program,
of which this conference is a part, was established in 1977 as a mechanism to
judge controversial topics in medicine and public health in an unbiased, impartial
manner. NIH has conducted 118 consensus development conferences, and 28 state-of-the-science
(formerly "technology assessment") conferences, addressing a wide range of issues.
