Cannabipiperidiethanone

Cannabipiperidiethanone is a synthetic cannabinoid of the aminoalkylindole family, in the phenylacetylindole subclass. Its structure combines the phenylacetylindole part of JWH-250 with the (1-methylpiperidin-2-yl)methyl nitrogen substituent of AM-2233. Uchiyama et al. (2011) identified it as an adulterant in a herbal product sold illegally in Japan, and measure an IC50 of 591 nM at CB1 and 968 nM at CB2 in a binding test. In the same study it ranks below JWH-250 (2.3 times less affine at CB1, 9.4 times less at CB2), and the source does not publish its functional efficacy. No human, clinical or toxicological data are published in the sources consulted.

Source

Laboratory. No natural occurrence: a wholly synthetic molecule, found in 2011 in a herbal product illegally distributed in Japan, where it was mixed with two other synthetic cannabinoids.

No biosynthetic pathway: the molecule exists in no living organism and is not among the cannabinoids of hemp. It belongs only to synthetic chemistry, within the aminoalkylindole class (phenylacetylindoles). Described here by chemical class only.

European Union

No harmonised control measure at European Union level has been identified for this molecule in the sources consulted. Control therefore rests on national law. This entry does not list the states that control it.

France

A narcotic in France, but by generic clause rather than by name. The molecule does not appear by name in the ANSM consolidated list of narcotics (updated 16 February 2026), but it meets point by point the family definition « indol-3-yl methanone » in annex IV: a « 1-(N-methylpiperidin-2-yl)methyl » substituent on the indole nitrogen and, on the methanone bridge carbon, a benzyl group (here a 2-methoxybenzyl, the ring being substituted or not). JWH-250, whose phenylacetyl motif it shares, is named within the same family. Possession, supply and use therefore fall under the narcotics penal regime. Reference text: decree of 14 October 2019, to which the ANSM list refers for this block.
