THCV is a varin cannabinoid: the same ring system as THC, but with a three-carbon (propyl) side chain instead of a five-carbon (pentyl) chain. The plant makes it as THCVA, which decarboxylates to THCV. Effects are reported to differ from THC, but human research is limited and GenetixBay makes no claims about them.
In practice
Most commercial flower shows THCV under 0.5% w/w or not detected. Some landrace and landrace-derived lines, notably from southern and eastern Africa and parts of Asia, have been reported with much higher shares of propyl cannabinoids, and breeders select for it with lab testing. Because the propyl branch starts earlier in the pathway (at the precursor), a plant high in THCV is usually low in pentyl THC, not high in both.
Don't confuse with
- THC: the pentyl (C5) analogue; far more common.
- THCVA: the acid form the plant makes before decarboxylation.
- CBV / CBDV: other varin cannabinoids, from the CBD and CBN families.
A cannabinoid is any compound that binds the body's cannabinoid receptors or shares the typical cannabis terpenophenolic structure; the plant-made ones are phytocannabinoids such as THCA and CBDA.THC (Δ9-tetrahydrocannabinol) is the neutral, decarboxylated cannabinoid mainly responsible for cannabis's reported intoxicating effects; the living plant makes it almost entirely as THCA.THCVA (tetrahydrocannabivarinic acid) is the acid precursor of THCV, made in trichomes from CBGVA when the plant's pathway starts from divarinic acid instead of olivetolic acid.Decarboxylation is the loss of a carboxyl group as CO2 that turns acid cannabinoids such as THCA and CBDA into neutral THC and CBD, quickly with heat, slowly with time.ND (non-detect) on a COA means the compound was not found at or above the method's limit of detection; it does not mean the amount is zero.A landrace is a traditional, locally adapted cannabis population kept by farmers in one region over many generations, with its own type and plenty of internal variation.CBD (cannabidiol) is a non-intoxicating neutral cannabinoid formed when CBDA decarboxylates; hemp-type and CBD-dominant cannabis make it mainly as CBDA in their trichomes.CBN (cannabinol) is a cannabinoid formed mainly when THC or THCA oxidises after harvest, so high CBN readings usually signal age, heat, light or air exposure, not plant ripeness.CBGA (cannabigerolic acid) is the precursor cannabinoid that the plant converts into THCA, CBDA or CBCA, formed by joining olivetolic acid to geranyl pyrophosphate.The chemotype ratio is the balance of a plant's main cannabinoids, usually THC to CBD, classing plants as type I (THC-dominant), II (mixed), III (CBD-dominant), IV (CBG) or V (near-zero).
