Smoking Cessation and Stimulant Treatment Study (S-CAST) cover

The primary objective of this study is to evaluate the impact of substance abuse treatment as usual plus smoking cessation treatment (TAU+SCT), relative to substance abuse treatment as usual (TAU), on drug abuse outcomes. The study will evaluate whether concurrent smoking cessation treatment improves, worsens, or has no effect on drug abuse outcomes in smokers who are in outpatient substance abuse treatment for cocaine or methamphetamine dependence. Secondary objectives include evaluating: 1) the efficacy of TAU+SCT, relative to TAU, in improving smoking outcomes; 2) the safety of TAU+SCT relative to TAU.
