Cannabidivarin (CBDV) is a non- psychoactive cannabinoid found in Cannabis. It is a homolog of cannabidiol (CBD), with the side-chain shortened by two methylene bridges (CH units). Plants with relatively high levels of CBDV have been reported in feral populations of C. indica ( = C. sativa ssp. indica var. kafiristanica) from northwest India, and in hashish from Nepal. CBDV has anticonvulsant effects.
Similarly to CBD, it has 7 double bond isomers and 30 stereoisomers (see: Cannabidiol#Double bond isomers and their stereoisomers). It is not scheduled by Convention on Psychotropic Substances. It is being actively developed by GW Pharmaceuticals (as GWP42006) because of a demonstrated neurochemical pathway for previously-observed anti-epileptic and anti-convulsive action. GW has begun a phase 2 trial for adult epilepsy, and is to begin trials of this CBDV product in children in 2016 in Australia.
