Summary

This study gave 100 healthy adults either 50 mg of CBG or a placebo to see how it affects anxiety, stress, mood, memory, and physical signs like heart rate and blood pressure. Researchers also tracked side effects like sleepiness or dry mouth. The goal is to better understand both the potential benefits and risks of CBG in humans.

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)
What this could lead to
If successful, this study could reveal whether CBG has benefits for stress, anxiety, or memory, and clarify its side effects.
What could go wrong
This is a small, early-stage study in healthy people, not patients. Results may not apply to real-world use or medical conditions.
