Nicotine dependence in alcohol-involved adults is a long-ignored treatment problem. The absence of its discussion in the literature is difficult to defend in light of medical and epidemiological data on the cost and prevalence of this dual addition. Most descriptive studies of alcohol abusers published in the past 20 years have reported tobacco use rates of at least 90%. There is a crucial need to educate treatment professionals and their clients about the additional health risks associated with joint nicotine dependence and alcoholism. Historically, certain barriers to active intervention have existed in drug abuse treatment facilities, including (1) concerns that urging clients to quit smoking might have an adverse effect on their maintenance of sobriety, (2) a tendency to minimize the strength and severity of nicotine addition, (3) a lack of informative data on how best to treat smoking in recovering alcoholics, and (4) financial issues related to marketing and insurance compensation. Recent data obtained from recovering alcoholics who have tried to quit smoking and anecdotal reports from alcoholism treatment centers that have begun addressing nicotine addiction are now challenging these barriers. Education, role modeling, environmental control, and development of staff expertise can be incorporated into standard alcoholism treatment programs to jointly treat these paired addictions.
