Study Summary

The first aim of this study is to determine whether a brain reward center (BRC) deficiency in patients with schizophrenia (SCZ) and cannabis use disorder (CUD) will be normalized when patients are given cannabis or dronabinol. The second aim will serve to further assess the effects of dronabinol on symptoms and medication side effects in this population.

Primary Outcome
