A surprising new study reveals that individuals with eating disorders find cannabis more effective for their symptoms than standard prescription drugs. Research from the University of Sydney suggests that cannabis for eating disorders like anorexia and bulimia could offer significant relief, pointing to a new direction for future treatment options.
The survey, published in the prestigious JAMA Network, offers a compelling patient-centered perspective on treatment efficacy, potentially pointing the way for future clinical research.

Patient Preferences: Cannabis and Psychedelics Take the Lead
The large-scale international survey gathered responses from over 7,600 people across 83 countries, all of whom identified as having a diagnosed or self-reported eating disorder. When asked to rate the effectiveness of various substances for their symptoms, the results were clear:
- Cannabis was rated the highest, with 56.1% of participants reporting it improved their symptoms.
- Psychedelics, including psilocybin (magic mushrooms) and LSD, were also rated highly for alleviating distress.
- These alternative options were rated significantly higher than standard prescription psychotropics like lisdexamfetamine or fluoxetine.
This data highlights a critical gap between what patients find helpful and what is most frequently prescribed in clinical practice.
Why Cannabis Might Help Restrictive Eating Disorders

The study uncovered an important nuance: the benefits of cannabis and anorexia were most pronounced. Patients with restrictive disorders like anorexia nervosa gave cannabis much higher ratings than those with binge-eating behaviors.
Researchers hypothesize that cannabis may help with anorexia by increasing the “hedonic value of food,” making eating a more pleasurable and less anxiety-provoking experience. For individuals struggling to consume enough calories, this appetite-stimulating effect can be therapeutic. Conversely, for those with bulimia or binge-eating disorder, this same effect could potentially worsen cycles of bingeing and purging.
Study Limitations and the Path Forward
While the findings are striking, the authors caution that the survey has limitations. Its reliance on self-reported data means results could be influenced by recall bias. “As such, our results should be interpreted as exploratory rather than definitive,” the study authors noted.
However, the strong patient feedback provides a powerful rationale for more rigorous, controlled clinical trials. Understanding why patients find cannabis for eating disorders so effective is the essential next step.
The conversation around mental health treatment is evolving, and this study adds a significant voice. It suggests that for millions seeking relief from eating disorders, future help may come from unexpected, yet promising, sources like cannabinoid and psychedelic therapy.
