HHC, or hexahydrocannabinol, is a cannabinoid extracted from hemp. It is similar in some ways to THC (tetrahydrocannabinol), the main psychoactive component of cannabis, but is obtained by a different process. HHC is usually produced by hydrogenation, in which hydrogen molecules are added to THC to change its molecular structure. This process is somewhat similar to the production of margarine from vegetable oil.
Legally, HHC is in a grey area in many regions, including the United States. It is often marketed as a legal alternative to THC because it is derived from hemp, which was legalised in the US by the 2018 Farm Bill. However, the legal status of HHC can vary depending on each state's laws and interpretation of federal regulations for synthetically produced cannabinoids.
In terms of effects, HHC is reported to produce similar effects to THC, such as euphoria, altered cognition and relaxation, although users often report that these effects are somewhat milder or different. The safety profile of HHC has not yet been extensively studied and, as with many novel cannabinoids, there may be risks associated with its use that are not yet well understood. As with any cannabinoid product, caution and moderation is advised.
