Cannabis for sleep? 35 years of data say otherwise
- Claim
- CANNABIS FOR SLEEP?
- Catch
- YOU WON'T FEEL IT
- Verdict
- NOT A SLEEP AID
Cannabis is widely promoted as a sleep aid, so researchers examined 35 years of follow-up from the CARDIA study — 1,266 middle-aged adults whose sleep was measured with 7-day wrist actigraphy, not just self-reports. Each additional cannabis-year of use was associated with higher odds of low sleep percentage (OR 1.10), more fragmented sleep (OR 1.04) and lying awake 30+ minutes after falling asleep (OR 1.21). Recent users were over four times more likely to sleep more than eight hours (OR 4.60). Yet cannabis use showed no association with how people rated their own sleep quality — the poorer sleep appeared in the objective data only. Long-term recreational cannabis use may work against midlife sleep health, even when it doesn't feel that way.
