People who stopped using cannabis after experiencing cannabis-induced psychosis and received four months of treatment showed no difference in dopamine D2 receptor availability in the caudate region of the striatum compared to former MDMA users and healthy controls. This suggests minimal lasting effects of cannabis-induced psychosis on dopamine reward mechanisms. A possible reduction in D2 receptor availability in the right putamen was observed, which may reflect a residual effect of antipsychotic medication rather than the psychosis itself.
