By Suchandrima BhowmikSep 21 2022Reviewed by Benedette Cuffari, M.Sc. A new Journal of Anxiety Disorders study assesses the association between medical cannabis use and sleep in Israel using an electronic diary method between April 2020 and April 2021.
Previous studies have indicated that 80-90% of patients with PTSD suffer from sleep impairments, with nightmares and insomnia among the most commonly reported symptoms. PTSD patients who experience a greater degree of sleep disturbances are more likely to suffer from severe PTSD, experience suicidal ideations, inflict self-injury, and be disabled.
Chemical composition of cannabis Cannabidiol and tetrahydrocannabinol are the two most studied chemical compounds found within cannabis. Early-phase clinical research studies have reported that THC can reduce the occurrence of nightmares and improve sleep quality in PTSD patients; however, most studies on CBD are restricted to pre-clinical animal models.
Daily sleep outcomes, including the number of times the participants woke up during the previous night, the frequency of nightmares, and whether they woke up too early without being able to fall back asleep, were measured. In addition, the time of the last MC use during the previous night, the time in which the patient fell asleep, and the CBD and THC concentrations of the primary MC products were also reported.
The mean PTSD severity was 47.57, while the average PSQI score was 10.19. A total of 22% of the participants reported using non-MC sleep aids during the study. Mean CBD and THC concentrations within the MC products were 4.35% and 18%, respectively. Conclusions The use of MC products appears to improve sleep problems associated with PTSD. However, further research, such as clinical trials, is needed to accurately understand the impact of MC, especially CBD, on overall PTSD symptoms and sleep disturbances.
