Abstract
Background: Cigarettes and coffee are widely used psychoactive substances among alcoholics. Due to the devastating public health impact of alcohol use disorders, it is important to determine if using cigarettes or coffee may influence alcoholism. Previous studies indicate that cigarette smoking is associated with progression of alcohol dependence, but the effects of coffee drinking have yet to be investigated. Objectives: To retrospectively determine the temporal sequence of incident cigarette, coffee, and alcohol use and attributed subjective effects in AA participants. Methods: Volunteers at all Nashville open-AA meetings (n = 289 [126 women], completion rate = 94.1%) were administered a Lifetime Drinking History modified to also include lifetime cigarette and coffee consumption, as well as coffee consumption and effects questions, the Fagerstrom Test for Nicotine Dependence, and the Smoking Effects Questionnaire. Results: Average ages (years) at first regular use of alcohol, cigarettes, and coffee were 15.4 (IQR: 13.0–18.0), 16.7 (IQR: 13.0–18.5), and 18.5 (IQR: 14.0–23.5), respectively. In a subset who used all three substances (n = 236;102 women) alcohol consumption preceded cigarette smoking (p < .001) and coffee drinking (p < .001), and cigarette smoking preceded coffee drinking (p < .001); these relationships did not differ by gender. Conclusions: Recovering alcoholics started regular alcohol consumption prior to cigarette smoking and coffee drinking. Scientific Significance: In AA participants, coffee does not precede initiation of regular smoking or alcohol drinking as might be anticipated for a gateway drug.
