A study published in the Journal of Affective Disorders showed a decrease in symptoms of obsessive-compulsive disorder (OCD) after consuming inhaled cannabis. The researchers analyzed data from 87 people who identified with OCD and tracked their compulsions, intrusions, and/or anxiety immediately before and after 1,810 cannabis sessions over a period of 31 months.

Researchers at Washington State University found that patients report a 60 percent reduction in compulsions, a 49 percent reduction in intrusions, and a 52 percent reduction in anxiety from before and after using cannabis. The researchers note that there was no placebo group.

In a statement, NORML deputy director Paul Armentano said there have been several studies evaluating “the potential efficacy of cannabis in alleviating OCD symptoms.”

ā€œThus, these results, although somewhat limited by study design, indicate that cannabis – and in particular the high CBD varieties – are promising as a therapeutic option for OCD patients and should be further investigated in more carefully designed controlled settings,” he said.

The study, published in May in the journal Depression and Anxiety – the world’s first placebo-controlled study of cannabis use in adults with OCD – involved 12 participants and concluded that although OCD symptoms and anxiety, of which patients themselves reported were reduced by cannabis use, ultimately “Has a small acute effect on OCD symptoms and produces less anxiety reduction compared to placebo.”
