NCT ID NCT06758596

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-phase study will give 144 healthy young adults (ages 18-21) a single dose of THC (7.5 mg) or a placebo in a capsule, then use brain scans and behavioral tasks to measure how THC affects mood, reward processing, and learning. The goal is to understand why some people respond differently to cannabis, which could inform future research on substance use disorders.

What this could lead to

If successful, this study could help explain why some people react differently to cannabis, potentially guiding future personalized treatments for substance use disorders.
