Ontario, Canada: The use of cannabis products is associated with perceived improvements in insomnia in patients suffering from either anxiety or depression, according to data published in the journal BMC Psychiatry.
A team of Canadian researchers assessed the effectiveness of cannabis in managing insomnia in a cohort of 677 subjects. Study participants suffered from either anxiety, depression, or from both conditions simultaneously. Subjects self-administered cannabis products at home and reported symptom changes in real time on a mobile software application. Investigators analyzed reports from over 8,400 cannabis-use sessions recorded over a three-year period.
“This naturalistic investigation of cannabis use for insomnia suggests that individuals with depression, anxiety, and comorbid depression and anxiety perceive benefits from using cannabis for sleep,” authors concluded. “In addition, compared to other cannabis strains, CBD-dominant products may be less helpful for sleep, specifically in individuals with depression. The current study highlights the need for placebo-controlled trials investigating the efficacy and safety of cannabinoids for sleep in individuals with mood and anxiety disorders.”
