Brief Summary:
Investigators aim to determine Epidiolex's promise as a pharmacotherapy for cannabis use disorder. Investigators hypothesize that Epidiolex, when added to medical management, will result in greater reductions in marijuana use compared to placebo as measured by the 2 primary outcome measures: 1) quantitative THC levels and 2) self-report by Timeline Follow Back. Secondary outcome measures will include treatment retention, patient satisfaction, cannabis withdrawal, cannabis craving, depressive symptoms, anxiety symptoms, , compliance, and cigarette use.

Condition or disease Intervention/treatment Phase
Cannabis Use Disorder Drug: Cannabidiol Drug: Placebo Phase 1

Detailed Description:
Investigators will conduct a Stage 1 pilot feasibility study at McLean Hospital to begin to evaluate Epidiolex as a pharmacotherapy for adults with cannabis use disorder. In this randomized, double-blind, placebo-controlled trial, cannabis-dependent subjects ages 18-65 will receive medical management over a 6-week period, with half receiving Epidiolex treatment and half receiving placebo. Participants will receive either up to 800 mg Epidiolex or placebo over a 6-week treatment period. Following treatment completion, participants will have a follow-up visits at 10 and 14 weeks. Primary outcomes will include self-report of cannabis smoking and results of quantitative urine drug screens for cannabis. Secondary outcome measures will include treatment retention, patient satisfaction, cannabis withdrawal, cannabis craving, depressive symptoms, anxiety symptoms, compliance, and cigarette use.

Exclusion Criteria:

  • Current diagnosis of other drug or alcohol dependence (excluding nicotine)
  • Recent (within 3 months) significant cardiac disease
  • Current serious psychiatric illness or history of psychosis, schizophrenia, bipolar type I disorder
  • Current medical condition (including significant laboratory abnormalities, such as abnormal liver function tests) that could prevent regular study attendance
  • Mental retardation or organic mental disorder
  • Acutely dangerous or suicidal behavior
  • Currently in a residential treatment setting in which substance use is monitored and restricted, since the restricted access to drugs could represent an important confounding variable
