NCT ID NCT07471347
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether cannabidiol (CBD) can reduce the amount of THC heavy cannabis users need to feel intoxicated. About 30 adults who use cannabis heavily will take a single dose of CBD or a placebo, then inhale THC using a vaporiser and decide when they've had enough. Researchers will measure how much THC they use, along with mood, thinking, and physical effects, to better understand cannabis tolerance.
