About this trial
Cannabidiol (CBD), one of the most prevalent cannabinoids in cannabis (marijuana) has been shown to reduce alcohol withdrawal symptoms in laboratory animals. In people without alcohol use disorder (AUD), CBD has been show to be effective in reducing anxiety, sleep problems, and seizures; all of these are common symptoms of alcohol withdrawal. This randomized placebo-controlled clinical trial will evaluate the potential of CBD to improve alcohol withdrawal symptoms and reduce craving during acute abstinence among individuals with moderate-to-severe AUD. Adult participants with moderate-to-severe AUD will be admitted to an inpatient research unit at the Johns Hopkins Hospital for a 5-day, 4-night stay that includes alcohol abstinence with management of their alcohol withdrawal. In addition to standard care, participants will receive CBD or placebo (no CBD), complete assessments of withdrawal, sleep quality and provide breath and blood samples.

Trial outcomes
Primary outcomes
Peak score on the Alcohol Withdrawal Symptom Checklist (AWSC)
The Alcohol Withdrawal Symptom Checklist (AWSC) is a validated measure in which participants report their own withdrawal symptoms. The scale consists of 17 items. The total possible score is 0-68, with higher scores indicating more severe withdrawal symptoms. The highest score for a participant across the duration of their time on the Clinical Research Unit (CRU) will be included in the analysis.
Peak score on the Clinical Institute Withdrawal Assessment for Alcohol, revised (CIWA-Ar)
The Clinical Institute Withdrawal Assessment for Alcohol, revised (CIWA-Ar) is a clinically administered measurement that represents the gold standard for assessing the severity of withdrawal symptoms. It consists of 10-items: nausea/ vomiting, tremor, paroxysmal sweats, anxiety, agitation, tactile disturbances, auditory disturbances, visual disturbances, headache, and orientation/clouding of sensorium. Each sign and symptom is rated on a Likert scale from 0-7 (with 0=absent and 7 =most severe), except for "clouding of sensorium," which is ranked from 0 to 4. Scores on the CIWA-Ar scale range from 0 to 67, with higher scores indicating more severe withdrawal. The highest score for a participant across the duration of their time on the CRU will be included in the analysis. Clinical staff will use these scores to justify administration of benzodiazepines to treat withdrawal symptoms.
Average total sleep time (minutes) and wake after sleep onset as measured by wrist actigraphy
Actigraphy will provide a primary assessment of sleep outcomes including total sleep time and wake after sleep onset. The actigraphy devices used will be triaxial accelerometers from Generation model 9 (GT9X) Link Wrist Actigraphy, Actigraph LLC. Values for total sleep time and wake time after sleep onset will be averaged across the study's four nights; this average will be included in the analysis.
Peak alcohol craving as measured by scores on the Alcohol Urge Questionnaire (AUQ)
The Alcohol Urge Questionnaire (AUQ) is an eight-item self-report questionnaire that has demonstrated validity and discriminative value in identifying and measuring alcohol craving. Each item is ranked on a score of 0 to 7, with a maximum score range of 0- 56. Higher scores indicate greater craving. The highest score for a participant across the duration of their time on the CRU will be included in the analysis.
Secondary outcomes
Average Total Sleep Time (minutes) as reported in Consensus Sleep Diary (CSD) results
The Consensus Sleep Diary (CSD) is a standardized subjective sleep rating measure in which participants rate features of their sleep-average total sleep time. Generally higher number is better.
Total Amount of Time (minutes) on Awakenings, as reported in Consensus Sleep Diary (CSD) results
The Consensus Sleep Diary (CSD) is a standardized subjective sleep rating measure in which participants rate features of their sleep- total amount of time on awakenings. Higher number indicating more awakenings (worse).
Sleep Quality as reported in Consensus Sleep Diary (CSD) results
The Consensus Sleep Diary (CSD) is a standardized subjective sleep rating measure consisting of nine items in which participants rate features of their sleep--sleep quality either "Very Poor," "Poor," "Fair," "Good," or "Very Good"
Sleep Latency (minutes) as reported in Consensus Sleep Diary (CSD) results
The Consensus Sleep Diary (CSD) is a standardized subjective sleep rating measure consisting of nine items in which participants rate features of their sleep - sleep latency (how long it takes one to fall asleep). Higher values would indicate worse sleep latency.
