NCT ID NCT05432284

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-stage study will give 32 healthy adults who use cannabis vaporized THC, beta-myrcene, or a placebo to see how these substances affect their feelings of being high and sleepy. Researchers want to learn how beta-myrcene, a compound found in cannabis and other plants, changes the body's response to THC. The study is not yet recruiting and is run by Johns Hopkins University.

What this could mean

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

Active substance

THC (cannabis) and beta-myrcene vapor

What this could lead to

If successful, this could help understand how beta-myrcene changes the effects of THC, potentially leading to better-informed cannabis use.

What could go wrong

This is a very early Phase 1 study with only 32 participants, so results may not apply broadly. It measures subjective effects, not real-world outcomes.
