This is a double-blind, placebo-controlled, parallel group study designed to assess the efficacy of full spectrum cannabidiol (CBD) and broad spectrum CBD, compared to a placebo control (PC), to reduce drinking in participants with moderate alcohol use disorder according to the DSM-V. If eligible for the study, subjects will be randomized to receive one of the conditions for 8 weeks.

Registry facts
The current study will directly test the hypothesis that a moderate dose of cannabidiol (CBD) leads to a reduction in alcohol consumption, alcohol craving, peripheral markers of inflammation, and anxiety. It is further hypothesized that CBD will lead to increased sleep duration and quality among individuals with AUD who want to quit or reduce their drinking. The study will also determine whether the small amount of THC found in full spectrum hemp-derived CBD products produces any negative effects. The hypotheses are grounded in previous studies suggesting that CBD reduces the reinforcing properties of alcohol and decreases drinking motivation and consumption (Viudez-Martínez, García-Gutiérrez, Fraguas-Sánchez, et al., 2018). Further, CBD has shown clinical promise for tobacco, cannabis, and opioid use disorders (Hurd, 2017; Hurd et al., 2015; Prud'homme et al., 2015), and evidence indicates that these effects may be due to the ability of CBD to reduce cue-induced craving and anxiety (Gonzalez-Cuevas et al., 2018; Hurd et al., 2019). The hypotheses are also grounded in the pre-clinical literature suggesting that CBD may modulate the immune system and have anti-inflammatory effects which also helps to reduce harm associated with alcohol and may have a positive effect on those attempting to quit. Other potential mechanisms that might underlie the effects of CBD include a reduction in the severity of acute withdrawal, a reduction in protracted withdrawal, and the neuroprotective effects of CBD. Given the background literature with respect to CBD and AUDs, a logical next step is for human studies to address these questions. To better understand the effects of hemp-derived CBD with and without a small amount of THC, the investigators propose a Phase II randomized clinical trial (RCT) to examine the safety, tolerability, and clinical effects of Full Spectrum CBD (fsCBD, contains less than 0.3% THC) vs. Broad Spectrum CBD (bsCBD, does not contain THC), vs. a matching placebo in a population of AUD subjects. This is a double-blind, placebo-controlled, parallel group study designed to assess the efficacy of fsCBD and bsCBD, compared to a placebo control (PC), to reduce drinking in participants with moderate alcohol use disorder according to the DSM-V. If eligible for the study, subjects will be randomized to receive one of the conditions for 8 weeks. To minimize risk of COVID transmission, the investigators will utilize Zoom for weekly subject check-ins and our Mobile Pharmacology Lab (MPL) for the collection of blood samples and clinical data for the majority of in-person visits. The initial Week 0 / Baseline visit will take place at the University of Colorado Anschutz Medical Campus. There will be MPL follow-up visits at Weeks 1, 4, and 8. Participants will be contacted by Zoom each remaining week during the 8-week period. A follow up Zoom interview will occur in Week 16 approximately 8 weeks after the end of dosing. Overall, the clinical study is expected to take 1-2 years to complete enrollment and data analysis.
