What is being measured
The primary outcome is the main question the study is designed to answer.
Prevalence of cannabis withdrawal
Descriptive statistics will be utilized to summarize cannabis withdrawal prevalence.
Measured: Up to 1 year
Severity of withdrawal symptoms
Assessed by the Cannabis Withdrawal Scale (CWS), a self-report instrument used measures the intensity of 19 cannabis withdrawal symptoms over the last 24 hours. Each item is rated on a 10-point Likert scale where 0=not al all and 10=extremely. Items are rated twice, first for intensity of symptom and then for negative impact on daily activity. Withdrawal symptom scores range from 0 to 190, with higher scores reflecting greater intensity of withdrawal symptoms.
Measured: Daily for first 4 days of hospitalization
Secondary outcomes (1)
Mortality Rate
Assessed for all-cause, in-hospital, and post-hospitalization mortality rates by review of the electronic medical record.
Measured: Up to 1 year
