Brief Summary:
The purpose of this pilot research study is to test the effects of a medication called nabilone (Cesamet) in adults with obsessive-compulsive disorder (OCD). Participants will receive either nabilone on its own, or nabilone in combination with a form of cognitive-behavioral therapy (CBT) called exposure and response prevention (EX/RP). Nabilone is a synthetic cannabinoid and acts on the brain's "endocannabinoid system," which has been hypothesized to play a role in OCD. Nabilone is approved by the FDA for the treatment of chemotherapy-induced nausea and vomiting. It is not FDA-approved for treating OCD.

Arms and Interventions

Arm Intervention/treatment
Experimental: Nabilone
Will receive nabilone at 1 mg daily (BID) over 4 weeks.
 Drug: Nabilone
Nabilone is a synthetic cannabinoid that is thought to be a Cannabinoid receptor type 1 (CB 1) agonist. It acts on the brain's "endocannabinoid system," which has been hypothesized to play a role in OCD.
Experimental: Nabilone and EX/RP
Will receive nabilone at 1 mg daily (BID) plus therapist-guided Exposure and Response Prevention Therapy during 4 weeks.
 Drug: Nabilone
Nabilone is a synthetic cannabinoid that is thought to be a Cannabinoid receptor type 1 (CB 1) agonist. It acts on the brain's "endocannabinoid system," which has been hypothesized to play a role in OCD.

Behavioral: Exposure and Response Prevention Therapy
Exposure and Response Prevention Therapy (EX/RP) is a type of Cognitive-Behavioral Therapy for OCD that involves intentionally confronting situations that trigger obsessional distress while refraining from doing compulsions.
