We are recruiting people who use opioids to participate in inpatient sessions where you will receive various psychoactive drugs, answer questionnaires about the drug effect, your general mood, and you will be asked to perform behavioral tasks and pain tolerance tasks. If you have physical dependence on opioids, you will receive daily maintenance doses to help lessen the symptoms of withdrawal.
Our studies require a stay in the hospital that can range from 4 to 9 weeks. Participants will need to qualify first based on a 30–60-minute phone screen and then 2-3 in-person screening visits that last 3-4 hours each.
