What are the synthetic compounds found in K2/Spice?


The synthetic cannabinoid chemicals that are typically found in K2 or “Spice” include the following:

  • JWH-018 (1-pentyl-3-(1-naphthoyl)indole)
  • JWH-073 (1-butyl-3-(1-naphthoyl)indole)
  • JWH-200 (1-[2-(4- morpholinyl)ethyl]-3-(1-naphthoyl)indole)
  • HU-210; HU-211; CP-47,497 (5-(1,1- dimethylheptyl)-2-[(1R,3S)-3-hydroxycyclohexyl]-phenol cannabicyclohexanol; CP-47,497 C8 homologue (5-(1,1-dimethyloctyl)-2-[(1R,3S)-3-hydroxycyclohexyl]-phenol)

What are synthetic cannabinoids?

Synthetic cannabinoids are chemical compounds that mimic the effects of THC – the principle active ingredients of cannabis. In 2008, Volker Auwarter, ScD, and colleagues in the forensic toxicology lab at the University Hospital Freiburg, Germany, found that the Spice herbal incense products contained at least two different designer drugs known as synthetic cannabinoids.

What are the classifications of synthetic cannabinoids?

Synthetic cannabinoids have been classified according to the chemical structures of the molecules, as suggested by Howlett et al. and Thakur et al. This classification has also been referred to in a report by the British Advisory Council on the Misuse of Drugs (ACMD) which deals with the generic definition of synthetic cannabinoids.

1.     Classical cannabinoids (THC, other constituents of cannabis; and their structurally related synthetic analogues e. g. HU-210, AM-906, AM-411, O-1184)

2.     Nonclassical cannabinoids (cyclohexylphenols or 3-arylcyclohexanols such as CP-47,497-C8, CP-55,940, CP-55,244)

3.     Hybrid cannabinoids (combinations of structural features of classical and non-classical cannabinoids, e. g. AM‐4030)

4.     Aminoalkylindoles (AAIs), which can be further divided into naphtoylindoles (e. g. JWH-018, JWH-073, JWH-398, JWH-015, JWH-122, JWH-210, JWH-081, JWH-200, WIN-55,212); phenylacetylindoles (e. g. JWH-250, JWH-251); naphthylmethylindoles and benzoylindoles (e. g. pravadoline, AM-694, RSC-4).

5.     Eicosanoids (endocannabinoids such as anandamide, and their synthetic analogs e. g. methanandamide)

6.     Others, diarylpyrazoles (selective CB1 antagonist Rimonabant®), naphtoylpyrroles (JWH‐307), naphthylmethylindenes or derivatives of naphthalene-1-yl-(4‐pentyloxynaphthalen-1-yl)methanone (CRA-13).


What is the legal status of synthetic cannabinoids in various countries?

In the United States, it was only on November 24, 2010 when the DEA notified the public through the Federal Register of their intent to temporarily control five synthetic cannabinoid chemicals found in so-called “fake pot” products such as K2 and Spice. At present, the control status of these compounds differs significantly from country to country.


The table below shows an overview on the legal status of synthetic cannabinoids in various countries based from the report released by the United Nations Office on Drugs and Crime (UNODC).
