Experimental timeline of study procedures. Participants completed a single TSST outpatient session. Of these, approximately half went on to complete the protocol of cannabis withdrawal and relapse under one of five broader inpatient studies. The number of days in each phase varied depending on the study the participants were enrolled: 1–2 days in which participants received standardized administration of active cannabis (Stabilization phase), and 2–3 days in which placebo dose of self-administered cannabis could be purchased (Withdrawal phase). Relapse was buying and using cannabis on the first day that active cannabis was made available for purchase.
