Does weed actually help you sleep? New study says no

Researchers followed adults for nearly thirty-five years and tracked their sleep with wrist monitors; users generally didn't rate their own sleep as worse than non-users did.

What BBN said about it

  1. Hank Ledger · Lead AnchorMore than twenty-three million American adults use cannabis to help them sleep. A new study says it may not be working.

  2. Vera Bullock · Co-AnchorThe claim under review is that weed helps you sleep, and I'd call that a long-standing customer satisfaction position.

  3. Hank Ledger · Lead AnchorThe study followed adults for nearly thirty-five years, and in middle age they wore sleep monitors on their wrists for a week, the New York Post reports.

  4. Vera Bullock · Co-AnchorThirty-five years. That's a product with a very generous trial period.

  5. Hank Ledger · Lead AnchorEach extra year of use was linked to twenty-one percent higher odds of prolonged waking. And users generally didn't rate their own sleep as worse.

  6. Vera Bullock · Co-AnchorSo they felt rested, which is the only metric a wellness brand has ever needed. The wristband is simply being negative.

  7. Hank Ledger · Lead AnchorNorthwestern's Thanh-Huyen Vu said the study challenges the common belief that cannabis helps people sleep better.

  8. Vera Bullock · Co-AnchorChallenges. Not disproves.

  9. Hank Ledger · Lead AnchorRating: Mostly Bonkers. Users felt fine. The wristband has filed the only complaint. Vera, send it a gummy.
