FOCUS Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Reduced Use ConditionExperimental Treatment1 Intervention
Participants in the reduced use condition will be provided mobile contingency management, in which they are paid to provide marijuana saliva readings that suggest they have been abstinent from marijuana use.
Group II: Control ConditionActive Control1 Intervention
Participants in the control condition will be asked to provide marijuana saliva readings, but they are not paid for abstinent readings. Instead, their payments are yoked to the average amount of payment made by two participants in the reduced use condition.
