HHCP-O-acetate

HHCP-O-acetate (HHCPO, HHCP-O) is a semi-synthetic derivative of tetrahydrocannabiphorol (THCP) derived in several steps by hydrogenation to hexahydrocannabiphorol (HHCP) followed by acetylation of the OH group. It has been found as a component of grey-market cannabis products such as e-cigarette liquids and edible gumdrops, and is allegedly a potent and long-lasting psychoactive cannabinoid.

Confusion about acronym
Some vendors have mistakenly claimed that HHCPO stands for hexahydrocannabinol propionate (HHC-P) or hexahydrocannabinol cyclopropyl ether, but these are different compounds.
