The primary aim of this research study (STEP) is to compare the effectiveness of two smoking cessation programs that integrate counseling and nicotine replacement with either a wellness program or exercise. This will help us to determine whether different lifestyle interventions (wellness or exercise) help increase the effectiveness of current standard programs for smoking cessation.
