Summary
This study looked at how the brain recovers after people stop using cannabis. Researchers used brain scans and EEG to measure changes in brain receptors and rhythms over four weeks of abstinence. The study included 162 people who were either cannabis-dependent or healthy non-users. The goal was to understand the brain's recovery process, not to test a treatment.
