at the CB₁ receptor of 22 nM, though some derivatives substituted at the 4-position of the naphthyl ring have potency more closely approaching that of the equivalent naphthoylindoles. This makes JWH-175 considerably less potent than most synthetic cannabinoid drugs used in synthetic cannabis blends, and it is unclear if JWH-175 has ever been used for this purpose. However it has still been explicitly banned in several jurisdictions including Russia and some Australian states, in order to stop its potential use as an ingredient in such products. In the United States, all CB₁ receptor agonists of the 3-(1-naphthylmethane)indole class such as JWH-175 are
