Cannabidiol in Anorexia Nervosa: A Double-Blind Randomized Placebo Controlled Pilot Study to Test Safety, Pharmacokinetics, and Symptom Change.
| Journal | The International journal of eating disorders |
| Study Type | Randomized Trial |
| Population | Human participants |
This represents the first randomized controlled trial examining CBD in anorexia nervosa, a psychiatric disorder with limited treatment options and significant morbidity. The study provides crucial safety and tolerability data for CBD use in this medically fragile population.
This double-blind, placebo-controlled pilot study randomized 32 women with anorexia nervosa or atypical anorexia nervosa to receive CBD (up to 6.25 mg/kg twice daily) or placebo for 21 days. The primary outcomes focused on safety, tolerability, and pharmacokinetics, with secondary measures examining eating disorder, depression, and anxiety symptoms. The study found CBD to be well-tolerated in this population, though the brief 21-day duration and small sample size limit conclusions about symptom efficacy.
“While encouraging from a safety perspective, this pilot study’s primary value lies in establishing tolerability rather than demonstrating clinical efficacy. The 21-day timeframe is insufficient to meaningfully assess symptom improvement in anorexia nervosa, which typically requires months to years of treatment.”

FAQ
Is CBD safe to use in patients with anorexia nervosa?
This pilot study found CBD to be well-tolerated in women with anorexia nervosa over a 21-day treatment period. The researchers monitored liver function and other safety parameters, with no significant adverse effects reported at doses up to 6.25 mg/kg twice daily.
What CBD dosage was used in this anorexia nervosa study?
The study used a gradual dose escalation protocol starting at 1.25 mg/kg twice daily and increasing weekly to a maximum of 6.25 mg/kg twice daily over 21 days. This titration approach allowed researchers to assess both safety and optimal dosing while monitoring for side effects.
Can CBD help with anxiety symptoms in anorexia nervosa patients?
The study investigated CBD’s potential to reduce anxiety through the endocannabinoid system, as anxiety is a key component of anorexia nervosa. While the researchers measured anxiety symptoms as an outcome, the specific results regarding anxiety improvement were not detailed in the provided summary.
How long does this study suggest CBD treatment should last for anorexia nervosa?
This was a short-term pilot study lasting only 21 days, primarily focused on establishing safety and tolerability rather than long-term efficacy. The optimal duration of CBD treatment for anorexia nervosa remains unclear and would require longer-term studies to determine.
Who was eligible to participate in this CBD anorexia nervosa study?
The study enrolled women with anorexia nervosa or atypical anorexia nervosa, with participants averaging around 22-23 years of age. The researchers included both typical and atypical presentations of anorexia nervosa, suggesting potential broader applicability across the anorexia spectrum.
