Why people use it
- Sleep onset
- Pain relief
- Appetite or nausea control
Evidence at a glance
Cannabinoid evidence is condition-, ratio-, dose-, and route-specific. THC may help selected medical symptoms but is not a low-risk general sleep aid, and a personal microdose should not be presented as a proven recommendation.
Confidence: moderate
