Studies on cannabis

Cannabis research has exploded since the 2010s. Thousands of studies are published every year in leading medical journals on the effects of THC and CBD, the mechanisms of the endocannabinoid system, potential therapeutic applications and the risks associated with regular consumption.

Newsweed deciphers these publications to make them accessible: randomized clinical trials, observational studies, meta-analyses, health agency reports. From results on epilepsy, chronic pain, anxiety and cancer to controversies over cognitive effects and driving: the science of cannabis, unfiltered and unapologetic.
