Tobacco Dependence Clinical Trial
Official title:
Reduced Nicotine Content Cigarettes in Smokers of Lower Socioeconomic Status
The overall goal of this study is to address the question of whether progressively lowering nicotine content in cigarettes can reduce or eliminate nicotine dependence in smokers of low socioeconomic status
To address the question of whether progressively lowering nicotine content in cigarettes can
reduce or eliminate nicotine dependence in low socioeconomic smokers, we will randomize
smokers to either an Reduced Nicotine Content group with a gradual step-wise reduction in
nicotine from 11 mg to 0.2 mg per cigarette in five 3-wk stages, or a control group with
nicotine content similar to their preferred usual brand of cigarettes.
Overall, we hypothesize that low socioeconomic smokers who switch to progressively lower
nicotine cigarettes will initially alter their smoking behavior to compensate for lower
nicotine until cigarette nicotine yields become so low that complete compensation becomes too
difficult. At that point, smokers will either drop-out or continue to smoke the reduced
nicotine content cigarettes but with incomplete compensatory behaviors.
