Cannabinoids: structures,effects, and classification

The data on the chemical structures, biological effects, and use of cannabinoids on the illegal market of new psychoactive substances were generalized. An extended classification comprising new classes, groups, and subgroups of cannabinoids was proposed for better representation of their structural variety. The emergence of new synthetic cannabinoids which belong to the groups of cycloalkanecarbonylindoles, indole- and indazole-3-carboxamides, and indoleand indazole-3-carboxylates is closely associated with the market of new psychoactive substances.
