HHC Added to "Schedule II" by UN Drug Commission | Update on 12/03/2025
At a session in Vienna, the United Nations Commission on Psychotropic Substances (CND) voted by qualified majority to classify hexahydrocannabinol (HHC) as a Schedule II substance under the 1971 Convention on Psychotropic Substances. This decision follows a recommendation from the World Health Organization (WHO) and effectively imposes an international ban on recreational and non-medical use of HHC.
HHC, often marketed as a THC alternative, is available in several countries. The ruling was widely anticipated by the industry, with the United States abstaining from the vote.
HHC in the United States: A State-by-State Breakdown
The legality of HHC in the US depends largely on state laws.
Federal Status
Under the 2018 Farm Bill, hemp-derived cannabinoids like HHC are technically legal if they contain less than 0.3% Delta-9 THC.
However, the psychoactive nature of HHC puts it in a gray area, with some states opting to ban or restrict it outright.
State Laws
- Legal: States like Florida, Texas, and Illinois permit the sale of HHC under hemp laws, provided it meets THC content limits.
- Restricted or Banned: States including California, Colorado, and New York have introduced bans or restrictions on synthetic cannabinoids, covering HHC.
ℹ️ If you’re planning to use HHC in the US, always check your state’s regulations to avoid legal trouble.
