What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cannabidiol (CBD)
- What this could lead to
- If it works, this could point toward a new way to ease anxiety around eating for people with anorexia nervosa.
- What could go wrong
- This is a very early, small study (40 people) focused on safety and dosing, not on proving effectiveness. CBD may not reduce anxiety or could cause side effects.
