Since the first synthetic cannabinoids were discovered in recreational drug products in 2008, new synthetic cannabinoids with no precedent in the scientific literature continue to be identified. These synthetic cannabinoids appear to be rationally designed by clandestine medicinal chemists. These unprecedented synthetic cannabinoids often feature alphanumeric code names intended to mimic the style of chemical nomenclature used by academic laboratories and pharmaceutical companies, and there is generally little, if any, information available regarding their pharmacology and toxicology at the time of first discovery.
