(what is this?) (verify) Tetrahydrocannabinol-C4, also known as THC-C4 and butyl-THC, is a homologue of tetrahydrocannabinol (THC), the active component of cannabis. They are only different by the pentyl side chain being replaced by a butyl side chain. It is unknown whether THC-C4 is an agonist, partial agonist, or antagonist at the cannabinoid receptors. The propyl analog, THCV, is a cannabinoid receptor type 1 and cannabinoid receptor type 2 antagonist, while THC is a CB  1 agonist. THC-C4 has rarely been isolated from cannabis samples, but appears to be less commonly present than THC or THCV. It is metabolised in a similar manner to THC.  Similarly to THC, it has 7 double bond isomers and 30 stereoisomers. 
It is not scheduled by
