From the Director
The use of tobacco products may be the Nation's most critical public
health problem. It is, in fact, addiction to nicotine that is at the root
of this enormous health, social, and financial burden.
An improved overall understanding of addiction, coupled with the
identification of nicotine as an addictive drug, has been instrumental in
the development of medications and behavioral treatments for nicotine
addiction. In essence, science-driven treatment development has provided
to consumers the option to easily purchase effective treatments, such as
the nicotine patch and nicotine gum, in their local drugstores and
supermarkets. Science has also shown that treating addiction with
medications alone is not nearly as effective as when the medication is
coupled with a behavioral approach. While we have made substantial
progress in developing both pharmacological and behavioral treatments that
have proven effective for many people, much more remains to be done.
Through the use of advanced neuroimaging technologies, we are now
actually able to see some of the changes in brain function that occur as
people smoke tobacco products. Researchers are beginning to find that
there may be chemicals other than nicotine in cigarette smoke that
contribute to tobacco's addictiveness. This finding and many other new
research accomplishments in the addiction arena are providing us with an
unprecedented opportunity to curtail this enormous public health crisis.
We hope this compilation of scientific information will help to inform
readers about our current understanding of nicotine addiction and its
harmful effects and will assist in prevention and treatment efforts.
