NCT00249509

Brief Summary

Recent research has identified the following withdrawal symptoms to be associated with abruptly stopping marijuana use: anxiety, irritability, bodily aches and pains, and difficulty sleeping. These symptoms resemble those of both depression and nicotine withdrawal, suggesting that a similar treatment drug may be useful. This study will evaluate the effectiveness of two antidepressant drugs, bupropion and nefazodone, in reducing withdrawal symptoms in marijuana dependent individuals.
