ClinConnect Summary

This clinical trial is studying the effects of two types of drugs: opioids (like morphine) and benzodiazepines (like alprazolam), especially when they are used together. The researchers want to understand how these drugs affect mood, thinking, and behavior in people who have a history of using them, either for medical reasons or not. Participants will be given different combinations of these medications or a placebo (a harmless sugar pill) in a controlled setting to see how each affects them.

To join the study, participants should be between the ages of 18 and 65 and have used opioids and/or benzodiazepines in the past 10 years. Importantly, they should not be seeking treatment for substance use issues and must be in good health. Throughout the trial, participants will undergo assessments and may experience different drug effects, helping researchers learn more about the risks and impacts of using these substances together. It’s essential to note that individuals with severe mental health issues, certain health conditions, or those currently using specific medications won't be eligible to participate.
