 Current cigarette smokers N550; 400 in formal study; up to 80-150 pilot will be randomly assigned to Usual Care UC, Standard Treatment ST or MBAT. UC will be four 5-10 minute counseling sessions following the problem-solving approach in the Treating Tobacco Use and Dependence Clinical Practice Guideline Guideline. ST is a standard smoking cessation group program using a problem-solvingcoping skills approach. MBAT is a group smoking cessation program derived from Mindfulness-Based Stress Reduction MBSR and Mindfulness-Based Cognitive Therapy. MBAT will not alter the basic mindfulness approach used in MBCT and MBSR, but will replace depression-related material with smoking cessation strategies from the Guideline. All participants will receive nicotine patches and self-help materials. MBAT mechanisms and effects will be assessed using implicit cognitive psychological measures and computer-administered questionnaires. Participants will be tracked from baseline through 4 UC or 8 ST and MBAT treatment visits and follow-up visits 1 and 23 weeks post-treatment.
