Cannabidivarin (CBDV, GWP42006) is a non-intoxicating psychoactive cannabinoid found in Cannabis.

It is a homolog (chemistry) of cannabidiol (CBD), with the side-chain shortened by two methylene bridges (CH2 units).

[1][2][3] CBDV demonstrated anticonvulsant in rodent models in a single published study.

[4] It was identified for the first time in 1969 by Vollner et al.[5] Similarly to CBD, it has seven double bond isomers and 30 stereoisomers (see: Cannabidiol#Isomerism).

It is being actively developed by GW Pharmaceuticals (as GWP42006)[6] because of a demonstrated neurochemical pathway for previously observed anti-epileptic and anti-convulsive action.
