HHC is chemically known as 11-Nor-9β-hydroxyhexahydrocannabinol. It is a semi-synthetic cannabinoid and a hydrogenated form of THC. HCC was first manufactured in 1944 by an American chemist known as Roger Adams. To produce HHC, Adams added hydrogen molecules to Delta-9 THC, converting THC to tetrahydrocannabinol (HHC). This process is known as a hydrogenation reaction. However, while Adams produced HHC from traditional cannabis-derived THC, a modern approach is used today. As a result of legislation and policies surrounding the possession and use of cannabis, low-THC cannabis plants and hemp are used to produce HHC.
