Study: Patients with Insomnia Report Improvements with Medical Cannabis

Ottawa, Canada: Patients with insomnia and other sleep disorders report subjective improvements following the use of cannabis and a significant percentage of them report being able to either reduce or discontinue their use of prescription medications, according to data published in the Canadian Pharmacists Journal.

Canadian investigators assessed the impact of marijuana on sleep disorders in a cohort of 38 patients authorized to access medical cannabis products. Patients were assessed at baseline and then three months after initiating cannabis.

Investigators reported that 71 percent of patients experienced subjective improvement in their sleep. Thirty-nine percent of the study’s subjects were able to either “completely discontinue [their use of] insomnia medications or reduce their use from nightly administration to as-needed administration with the use of medical cannabis.”

The study’s results are consistent with other observational studies, such as those here and here, finding that patients with sleep disorders typically experience improvements in their symptoms from cannabis. 

Authors concluded, “[O]ngoing clinical trials of cannabinoids in patients living with insomnia are integral to ensuring evidence-based decisions on the role of cannabinoid therapies in the treatment of sleep disorders.”
