Cannabivarin, also known as cannabivarol, is considered a non-psychoactive cannabinoid — it does not produce the euphoric side effects found in THC. Minor amounts of CBV are found in the hemp plant Cannabis sativa. It is an analog of cannabinol with the side chain shortened by two methylene bridges. Wikipedia
CBV is the second most occurring cannabinoid in the cannabis plant. Just like CBD, CBV is a non-psychoactive cannabinoid I.e. it does not get the user high.
CBV is a member of the phytocannabinoids group, which has other cannabinoids like cannabichromene and cannabigerol (CBG). As far as the chemistry of CBV is concerned, CBV has no double bond isomers or stereoisomer.
