Large Study Links Cannabis Use to Sleep Disruption, Especially Among Heavy Users - ScienceAlert
Now, a large-scale study on the effects of cannabis on sleep duration and quality has called into question the drug's reputation as a beneficial pre-slumber choice. .The authors of the new study, led by researchers at the University of Toronto in Canada, wanted to determine the relationship between recent cannabis use and sleep duration in a nationally representative sample from the US.Sleep duration was categorized as short, optimal, or long, with short sleep defined as less than 6 hours, and long sleep defined as more than 9 hours on average weeknights or worknights.The cannabis users surveyed were 34 percent more likely to report sleeping fewer than 6 hours per night when compared to non-users, as well as being 56 percent more likely to report sleeping more than 9 hours when compared to non-users, after accounting for potential confounding factors. .Previous findings have shown mixed results pertaining to the effectiveness of cannabis as a sleeping aid, with some studies showing that even a single cannabis exposure can reduce sleep-onset latency, increase total sleep time, and report less disruption once asleep.
