NCT ID NCT05006079

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing how opioids (morphine) and benzodiazepines (alprazolam) affect mood, anxiety, and thinking when taken alone or together. Researchers will give 24 people with a history of using these drugs single doses in a lab and measure their responses. The goal is to understand the effects of combining these substances, which could inform future treatments or policies for polydrug abuse.

What this could lead to

If successful, this could help understand how combining opioids and benzodiazepines affects people, potentially guiding better treatment or policies for polydrug abuse.

What could go wrong

This is a small, early-phase study with only 24 participants, so results may not apply broadly. It tests single doses in a lab, not real-world use, and may not lead to direct treatments.
