Reducing Cannabis Use for Sleep Among Adults Using Medical Cannabis
In Brief
A clinical study evaluating Cognitive Behavioral Therapy for Insomnia in Cannabis Users (CBTi-CB) and Sleep Hygiene Education (SHE) for Insomnia Chronic and Cannabis Use. Completed, enrolled 57 participants across 2 sites.
Detailed Summary
As medical cannabis use becomes more common in the United States, it is essential to understand the ways in which adults who use medical cannabis perceive the benefits of cannabis use and to identify effective strategies to help them cope with these problems. Emerging data indicate that insomnia and/or use of cannabis for sleep are very common in medical cannabis patients. The present study will adapt and gather pilot data on the impact of a Cognitive Behavioral Therapy for insomnia (CBTi-CB) intervention on sleep- and cannabis-related outcomes in adults who use medical cannabis.
Study Details
Timeline
Interventions
Each CBTi-CB therapy session will review the previous week of sleep/wake diaries and summarize key sleep parameters with participants. The treatment will address cannabis use by increasing use of appropriate coping strategies and improving self-efficacy to manage insomnia and next-day consequences. The content includes: (1) Sleep Scheduling Strategies to consolidate sleep using behavioral strategies that increase the drive for sleep and stabilize the circadian timing system; (2) Sleep Hygiene to discuss behaviors, substances, and environmental conditions that can help or hinder sleep; (3) Cognitive Therapy aims to identify and alter dysfunctional beliefs about sleep and functioning that contribute to insomnia; (4) Counter-Arousal Strategies address ruminative thoughts and increased body tension interfering with ability to fall or return to sleep; (5) Relapse Prevention for Insomnia reviews treatment gains and the behavioral and cognitive strategies that were most helpful.
The SHE condition will be matched to the CBTi-CB condition in terms of level of attention and the non-specific aspects of receiving social support from a study therapist, without providing individualized recommendations. The current content includes: (1) Insomnia History of the participant, including triggers that initiated the problem, duration, severity, and frequency, premorbid sleep characteristics, and previous sleep treatments; (2) Sleep Education about why we sleep, sleep stages, sleep regulation at night, and sleep changes across lifespan; (3) Substance Use and Sleep and the effects of cannabis and other licit and illicit substances on sleep; (4) Environmental Factors that contribute to a sleep-conducive environment; (5) Lifestyle Factors like the effects of diet, exercise, and napping on sleep; (6) Sleep Maintenance Strategies to review treatment gains from the participant's perspective and emphasize the principles covered to maintain sleep improvements.
