HHC

Hexahydrocannabinol (HHC) is a hydrogenated derivative of tetrahydrocannabinol (THC). It is a naturally occurring phytocannabinoid that has been rarely identified as a trace constituent in sowing ends, but can also be produced synthetically by hydrogenation of hemp extracts. HHC was first synthesised in 1947 by Roger Adams using natural THC found in hemp seeds.

HHC is a psychoactive substance whose effects are very similar to those of THC. According to Czech legislation, this cannabinoid is not included in the list of illegal addictive substances.
