How CBD changes THC's effects: a dose study
Part of Mental health clinical trials.
This study tests different ratios of CBD to THC to see how CBD can change the effects of THC. It may help people who use cannabis occasionally understand how CBD can reduce unwanted side effects.
Summary written for real people, not researchers, by Clin2.

This study looks at how taking CBD (a cannabis compound that doesn't get you high) affects your cannabis use. It is for healthy adults who use cannabis for recreational reasons, not for medical treatment.
This Phase 1 study tests how delta-9 THC (the main active ingredient in cannabis) affects healthy adults, and whether the effects differ by gender. It may help researchers understand risks and responses to THC, which could guide safer use and future treatments.
This study looks at how natural hormones in women affect the way they respond to cannabis. It may help explain why some people feel stronger or different effects from cannabis.
This Phase 1/2 study tests whether inhaled cannabidiol (CBD) is safe and well-tolerated in healthy people who use cannabis occasionally. You’d be asked to avoid other cannabis and certain drugs around study visits so researchers can measure your response clearly.
This Phase 1 study tests how THC (the main active ingredient in cannabis) affects healthy adults, and whether effects differ by gender. It’s designed to learn about short-term body and brain responses to THC.
This study uses brain scans (fMRI) to see how THC (the active ingredient in cannabis) affects the brain as people age. If you are a cannabis user without current dependence or health issues, you may help researchers understand these effects.
