Marijuana and eating disorders: new study tests if education can spark change
NCT ID NCT07387965
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a brief education session about cannabis risks can increase knowledge and motivation to reduce use among people with eating disorders. 80 patients will receive either cannabis education or sleep hygiene education during their first week of a 20-week eating disorder program. Researchers will measure changes in knowledge, intention to cut back, and treatment outcomes.
