Abstract
Use of cocaine has been reported to increase cigarette smoking, but there are no published studies of cigarette smoking during early cocaine abstinence. The authors assessed ad libitum cigarette smoking of 12 cocaine-dependent smokers housed on a closed research ward. Last cocaine use averaged 0.6grams 1.8 days before admission. Smoking was measured indirectly with computerized cigarette dispensers. There was no significant difference between self-reported daily number of cigarettes smoked before admission and the number of cigarettes dispensed daily for the first 7 full days after admission. These findings suggest that early cocaine abstinence does not significantly alter cigarette smoking.
