Official title

Effects of Marijuana on Symptoms of Obsessive-Compulsive Disorder

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this pilot research study is to test whether certain components of the marijuana plant, known as "cannabinoids", may help to reduce symptoms in patients with OCD. Specifically, patients enrolled in the study will smoke marijuana containing different concentrations of 2 different cannabinoids, THC and CBD. Both of these agents act on the brain's "endocannabinoid system," which has been hypothesized to play a role in OCD. Neither compound is currently FDA-approved for treating OCD.
