Summary
This small study tested whether Epidiolex (a prescription CBD oil) can safely reduce symptoms of obsessive-compulsive disorder, hair-pulling, Tourette syndrome, and hoarding. Four adults took the drug for two weeks. The goal was to see if symptoms improved and if the drug was well-tolerated.
