What this could lead to
If successful, this study could help us understand how the brain recovers after stopping cannabis use, potentially guiding future treatments for cannabis dependence.
What could go wrong
This is an observational study, not a treatment trial. It only measures brain changes and does not test any therapy, so it won't directly lead to a new treatment.
