A May 2023 study entitled "Cannabis and Sleep Disorders: Not Ready for Prime Time? A Qualitative Scoping Review" that was published in the Journal of Clinical Sleep Medicine explored "a qualitative scoping literature review for studies involving the effects of cannabis on sleep and sleep disorders."
Cannabis & Sleep Disorders Study Design
Cannabis & Sleep Disorders Study. The design of this scientific investigation was that of a literature review that employed two electronic databases, MEDLINE and EMBASE, to search for previous clinical trials involving humans. "Inclusion criteria were article of any type, published in English, a target population of cannabis users, and reported data on cannabis effect on sleep and sleep disorders," reported the study.
"In 21 percent of participants, cannabis improved sleep. However, in 48 percent of patients, sleep worsened."
The study identified 40 publications that qualified for its inclusion criteria. Most (83 percent) were from the Americas and 60 percent had been published within the past decade. "Of the 40 studies, only 25 percent were randomized control trials." The study's authors also reported that sleep outcome data "were similar and comparable in only 20 percent" of studies reviewed.
Cannabis & Sleep Disorders Study Results
Cannabis & Sleep Disorders Study. Of the cannabis users within the patient cohort, 73 percent were "frequent cannabis users" and 27 percent were "sporadic users." In 21 percent of participants, cannabis improved sleep. However, in 48 percent of patients, sleep worsened. Fourteen percent of study participants reported mixed results, while 17 percent noted "no impact at all."
"Our findings summarize the lack of robust evidence to support the use of cannabis for sleep disorders."
Cannabis & Sleep Disorders Study Conclusions
Cannabis & Sleep Disorders Study. The study published the following conclusion:
"Our findings summarize the lack of robust evidence to support the use of cannabis for sleep disorders. The varied cannabis user-related characteristics may account for the inconsistent results identified. Further studies assessing cannabis and sleep are needed to discern what works in what context, how it works, and for whom."
