9-Nor-9β-hydroxyhexahydrocannabinol (9-nor-9beta-HHC; sometimes incorrectly confused with 11-nor-9β-hydroxyhexahydrocannabinol^[1]) is a cannabinoid first discovered from early modifications to the structure of THC, in a search for the simplest compound that could still fulfill the binding requirements to produce cannabis-like activity.^[2]^[3]

11-Hydroxyhexahydrocannabinol is the structurally related methylene homologue of 11-nor-9β-hydroxyhexahydrocannabinol that has been found as a minor active metabolite of tetrahydrocannabinol, and also a metabolite of the trace cannabinoid hexahydrocannabinol.^[4]
