Canbisol (Nabidrox) is a synthetic cannabinoid derivative that is the dimethylheptyl homologue of 9-nor-9β-hydroxyhexahydrocannabinol (HHC). It is a potent agonist at both the CB₁ and CB₂ receptors, with a binding affinity of 0.1 nM at CB₁ and 0.2 nM at CB₂. It is mainly used in scientific research, in receptor binding studies to determine the structure and function of the cannabinoid receptors, but has been made illegal in some countries due to its possible abuse potential as a cannabinomimetic drug.
