OBJECTIVE: To review the literature on nicotine dependence, nicotine pharmacology, health consequences associated with the use of nicotine, and nicotine replacement therapies used to aid smokers who are nicotine dependent. DATA SOURCES: A review of articles, book bibliographies, and published studies identified by a search of the MEDLINE database from 1982 to 1996 on nicotine dependence, nicotine addiction, nicotine withdrawal, smoking, smoking cessation, smoking intervention, nicotine pharmacology, nicotine pharmacokinetics, nicotine pharmacodynamics, and nicotine replacement therapies. STUDY SELECTION AND DATA EXTRACTION: Inclusion criteria were published randomized, double-blind trials of at least 12 weeks' duration, meta-analyses, and panel consensus guidelines. DATA SYNTHESIS: Cigarette smoking and tobacco use have met the surgeon general's primary criteria as well as additional criteria for drug dependence. Drug dependence requires that the drug produce psychoactive effects. Nicotine has been identified as the cause of tobacco dependence. First, nicotine provides positive reinforcement by stimulating nicotinic receptors to promote high self-administration rates. Second, nicotine causes a negative reinforcement in the form of withdrawal symptoms when nicotine is withheld after chronic use. Nicotine replacement therapy reduces the severity of withdrawal symptoms in smokers abstaining from tobacco. Nicotine replacement therapy allows the smoker to focus on psychosocial aspects of tobacco abstinence while receiving relief from withdrawal symptoms. The long-term effectiveness and health benefits of nicotine replacement therapy coupled with nonpharmacologic approaches have been clearly established. Smoking cessation has received wide attention from the public and medical communities; it is complex and has several interwoven factors to be considered. The psychological, behavioral, and physical components have to be understood before designing a treatment plan. The most successful approaches to smoking cessation involve multicomponent, multisession behavioral treatment programs as a foundation coupled with pharmacologic intervention. Pharmacists can play a key role in initiating behavior change and ensuring the safe and proper use of nicotine replacement in order to produce the desired outcome. CONCLUSIONS: The optimum choice in nicotine replacement depends on the individual's needs and coping abilities. Individualized nicotine replacement coupled with nonpharmacologic interventions produces the highest rate of success for abstinence from nicotine.
