The role of nicotine and non-nicotine factors in tobacco addiction. Nicotine is the primary psychoactive substance in tobacco smoke. However, prior research has demonstrated that nicotine and nonnicotine factors play different roles in the initiation, use and relapse to tobacco smoking. CfAST researchers have conducted neuroimaging and behavioral pharmacology research to understand the influence of nicotine and nonnicotine factors on neurocognition and smoking reinforcement. In a recent, landmark study, we evaluated the effects of reducing nicotine levels in cigarettes on smoking behavior and are continuing to evaluate this question in ADHD and HIV-infected smokers.
