Study Summary
Reduced drug use is a clinically meaningful target for treatment development, but few studies have evaluated the positive impacts produced by this behavioral change, preventing adoption of this endpoint in clinical trials. The proposed research will fill that critical knowledge gap by demonstrating the biopsychosocial benefits of reduced cocaine use. These data will be used to change current accepted cocaine treatment endpoints and accelerate identification of therapies for cocaine use disorder.
Primary Outcome
Endothelin-1 levels will be measured. They will be recorded in pg/ml.
