Treatment of Cannabis Use Disorder Among Adults With Comorbid Attention-Deficit/Hyperactivity Disorder
Completed · Phase 2/Phase 3 · Has a placebo group
Conditions studied: Cannabis Use Disorder, Attention-deficit/Hyperactivity Disorder
In brief
The proposed protocol is a double-blind, placebo-controlled outpatient study of the safety and benefit of Extended-release mixed amphetamine salt (Adderall-XR, MAS-XR) in the treatment of individuals with Cannabis Use Disorder (CUD) and Attention-deficit/Hyperactivity Disorder (ADHD). The investigators plan to enroll 50 and randomize 40 of these patients in the trial. The primary objective of the study is to determine the efficacy of MAS-XR in promoting cannabis abstinence among individuals with CUD and in promoting a decrease of ADHD symptoms.
