Where Is HHC-O Legal? Updated 2026

HHC-O is the acetated version of HHC, offering a potency 1.5 times stronger by adding an acetate to hexahydrocannabinol.  The result is a cannabinoid that behaves almost exactly like delta 9 THC.  And, given that, it’s understandable that a lot of people aren’t sure whether or not the cannabinoid is even legal.  So, let’s explore the somewhat confusing laws so that you know whether or not you can legally enjoy HHC-O.

Is HHC-O Legal Under United States Federal Law?

HHC-O is a federally legal cannabinoid, even though its effects are so similar to delta 9, and there are no restrictions on product concentration/strength, product form or purchase amount.  That’s because HHC-O complies with the Farm Bill that passed in 2018, to legalize all hemp derivatives as long as they contain a maximum of 0.3% delta 9 THC.  

What are the HHC-O Laws According to Each State?
