Summary

This study will give 22 occasional cannabis users oral THC, CBD, both, or a placebo to measure how these substances appear in blood and saliva, and how they affect thinking and behavior. The goal is to better understand drug detection and impairment from oral cannabinoids. It is an early-phase trial that does not aim to treat any disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
THC and CBD (cannabinoids)
What this could lead to
If successful, this could improve understanding of how oral cannabinoids affect driving impairment and drug testing.
What could go wrong
This is a very small, early-phase study (22 people) in occasional users only, so results may not apply to heavy users or real-world settings.
