Hexahydrocannabutol

Hexahydrocannabutol (HHCB, HHC-B) is a semi-synthetic cannabinoid derivative, the hydrogenated derivative of tetrahydrocannabutol (THCB). It was first synthesised by Roger Adams in 1942 and produces only weak cannabinoid-like effects in animals. More recently it has been sold as an ingredient in grey-market cannabinoid products.
