isn't CBD shceduled in the US? anyhow, it binds to 5-HT1a, some TRP receptors, and GPR55 as well as a couple others. 5-HT1a is an inhibitory receptor distributed throughout cortical areas, and so will have anti-anxiety effects when activated; this is the main mechanism of buspirone
. it is neuroprotective, but then again so are all other phytocannabinoids, but it seems to exert a calming effect and supposedly has notable anti-psychotic properties. Research shows CBD has the ability to modulate the effects of THC in such a way to decrease anxiety or paranoia it causes.
