## Key points

- Cannabis use was linked to poorer sleep measurements.
- Users did not report worse sleep.
- The study found an association, not proof of cause.

## Summary

A long-term study suggests that cannabis use is associated with poorer objectively measured sleep, despite many people using it as a sleep aid. The findings challenge the belief that cannabis reliably improves sleep, but show an association rather than proving that cannabis causes sleep problems.

Researchers followed 1,266 people for almost 35 years and assessed their sleep in middle age using wrist monitors and surveys. Greater lifetime cannabis exposure was linked to lower sleep efficiency and more disruption; recent users were also more likely to sleep for over eight hours. Users did not rate their sleep as worse, and the study did not account for how cannabis was taken.
