Study Finds Link Between Cannabis Use and Poor Sleep - Gizmodo

People who regularly use cannabis may be more prone to sleep problems, new research suggests.

These sorts of studies can only show a correlation between two factors, like cannabis use and poor sleep, not a cause-and-effect link.

“We determined there to be a possible exposure-response relationship between frequency of use and sleep duration; heavy users were at the greatest risk of both extremes of nightly sleep duration compared with non-users,” the authors wrote.

It’s a question that’s all the more important given that cannabis is increasingly becoming legalized throughout the U.S., not to mention the long-running problems with sleep that many Americans already experience regularly
