Summary

This early study tests whether vaporized cannabigerol (CBG) and THC can help with pain and appetite. Twenty occasional cannabis users will receive different doses of CBG and THC, alone or together, and report their pain tolerance, hunger, and any side effects. The goal is to see if these compounds are safe and effective for these symptoms.

What this could mean

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

Active substance
Cannabigerol (CBG) and Delta-9-tetrahydrocannabinol (THC) vaporized
What this could lead to
If it works, this could point toward a treatment for pain and appetite loss using cannabis compounds.
What could go wrong
This is a very small, early-phase study with only 20 participants. Results may not apply to everyone, and the compounds may cause intoxication or abuse potential.
