Brief Summary:
This study will be a randomized, double-blind, placebo-controlled, multicenter trial conducted to evaluate whether PP-01 mitigates the withdrawal symptoms associated with discontinuing cannabis in participants with moderate to severe Cannabis Use Disorder (CUD). The study will enroll approximately 225 participants with moderate to severe CUD and will include 5 arms, including a placebo arm, to help assess the incidence and severity of withdrawal symptoms in heavy long-term users of cannabis. Participants receive study medication for 34 days and participate in 11 visits (7 at a clinic and 4 telemedicine).
