Abstract

Nicotine addiction is the leading cause of premature illness and death in the general population. Up to half of all cigarettes are consumed by a minority of the population: persons with schizophrenia and other forms of mental illness. Ironically, despite nicotine dependence being considered a serious and deadly form of addiction in the general population, research on smoking in mental illness is predominantly guided by the idea that smoking has beneficial medication-like treatment effects. This article considers pitfalls of adherence to the self-medication hypothesis as an exclusively held dogma. New evidence from animal modeling work suggests the need to broaden hypothesis-driven research on smoking in mental illness. Adolescent smoking could predispose to mental illness and/or increased nicotine dependence in schizophrenia may represent an involuntary, general addiction vulnerability that has little to do with the 'helpful' psychoactive effects of nicotine or other drugs.
