The first week after attempting to quite cigarette smoking is the hardest period to succeed. Research shows that individuals able to remain cigarette free for this first week are significantly more likely to quit the smoking habit. In this study, sponsored by the National Institutes of Health, we are evaluating a new tool to assist individuals with quitting cigarette smoking. Transcranial magnetic stimulation (TMS) is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether 10 daily sessions of TMS over the forehead can help decrease smoking rates in treatment-seeking individuals.
The purpose of this study is to evaluate the potential mechanism of action and the safety of GET73, a new drug under development for the reduction of craving and drinking in alcohol dependent individuals. The study involves five to six visits over a three to four week period, including one to two assessment visits and two visits during which participants will be assigned to take, in a double-blinded fashion, both GET73 and a placebo (two visits during each condition). During three of these visits, participants will undergo a one-hour MRI scan. Compensation is available for qualified participants.

The purpose of the study is to explore the effects of progesterone on cannabis withdrawal in women who regularly smoke marijuana. Participants will be asked to abstain from marijuana use for 5 days after the onset of menses. They will receive 8 doses of either progesterone or placebo during this time. On Days 1 and 5 they will come to the clinic to complete study assessments and provide urine, saliva and blood samples.On Days 2-4 assessments will be completed via text messages, Redcap surveys and video calls. Participants will be monitored for adverse events and cannabis withdrawal on each study day.
This study examines the effects of the medication gabapentin and the supplement n-acetylcysteine among individuals with Bipolar Disorder who regularly drink alcohol.

This study is designed to evaluate the safety and effectiveness of using two different medications (extended release naltrexone and bupropion) compared to matching placebo (an inactive substance) in the treatment of methamphetamine use disorder.
