抽象

Cannabidiol (CBD) is a bioactive cannabinoid compound in marijuana (cannabis sativa), but unlike Δ9 tetrahydrocannabinol (THC), lacks the psychoactivity effect of THC. Available evidence suggests that there are marked therapeutic CBD effects for diverse disease processes including inflammation, cancers, psychosis, and epileptic seizures. The purpose of this study, in both younger and older healthy humans, is to improve our understanding of how CBD might control and regulate blood vessel health as well as cognitive and exercise performance.
