Two behavioral treatments for smoking reduction: a pilot study

Abstract

This study compared two behavioral treatments on their efficacy and acceptability in reducing smoking, using a crossover design with interposed return to baseline, 2 weeks/condition. 20 US cigarette smokers reporting an interest in reducing, but not quitting, their smoking either increased the inter-cigarette interval or selected easy cigarettes to eliminate, with a goal of 50% reduction. Nicotine gum accompanied both treatments. Measurements taken were self-reported cigarettes per day, carbon monoxide, cotinine, and thiocyanate; self-rated acceptability of the treatments; adverse events. Both treatments decreased self-reported cigarettes per day (-45% and -38%) and carbon monoxide (-20% and -19%), but not cotinine or thiocyanate. Increasing the inter-cigarette interval produced slightly more reduction in cigarettes per day than cigarette selection, but no other differences were found. Both treatments were acceptable and safe. Although our sample size was small and the duration of reduction documented short, both treatments appear to be acceptable and efficacious behavioral treatments for reduction.
