What is HHC?

HHC (hexahydrocannabinol) is a hydrogenated form of THC. It's created by adding hydrogen molecules to THC through a chemical process. HHC produces psychoactive effects similar to Delta-9 THC but is slightly less potent. It gained popularity as an alternative in states that banned Delta-8.

Federal Status

HHC falls under the 2026 total THC calculation. As a THC isomer, it will be included in the controlled substance classification.
