People with anxiety experience better quality sleep on days when they use marijuana compared to days when they use alcohol or nothing at all, a new federally funded study has found.
For the study, published in the journal Drug and Alcohol Review, researchers at the University of Colorado, Colorado State University and University of Haifa analyzed the subjective sleep quality of 347 people who reported using cannabis to treat anxiety. They wanted to understand the different ways sleep was affected by the use of marijuana, alcohol, neither or both on a given day.
To that end, people participating in the study were asked to fill out daily surveys for 30 days, recounting their substance use and subjective sleep experience the night prior. Researchers compared outcomes from non-use days, cannabis-only days, alcohol-only days and co-use days.
“Compared to non-use, participants reported better sleep after cannabis-use-only and after co-use, but not after alcohol-use-only,” the authors, who received funding for the study from a National Institutes of Health grant, wrote.
