Transcranial Magnetic Brain Stimulation to Reduce Cannabis Use in Heavy Cannabis Users

The growing legalization of cannabis across the U.S. is associated with increases in cannabis use, and accordingly, an increase in the number of individuals with cannabis use problems, including cannabis use disorder (CUD). While there are several medications being investigated as treatment options for CUD, none have been FDA-approved, and there is limited efficacy of traditional behavioral therapy approaches for this population. Consequently, there is a pressing need for the development of new treatments, including approaches that specifically target the brain areas associated with problematic cannabis use behaviors. Elevated attention to drug cues is one of the primary causes of relapse in heavy cannabis users. Preliminary data suggests that repetitive transcranial magnetic stimulation (rTMS), a non-invasive form of brain stimulation, may be a novel brain-based tool to decrease heightened attention to drug cues in people with CUD. Building on prior data, the primary goal of this study is to evaluate the feasibility and effectiveness of TMS as a tool to decrease attention to drug cues and reduce cannabis use. In this study, fifty (50) treatment-seeking, near-daily cannabis users will be recruited to receive either active or sham (placebo) repetitive TMS (rTMS). Participants will complete a total of 25 treatment sessions, delivered as five sessions per day across five days, with sessions flexibly scheduled over a two-week period. Measures of cannabis use and brain activity w…
