In plain terms
JWH-007 is a synthetic cannabinoid made in a laboratory, designed at the outset as a research tool. It does not exist in hemp and has nothing to do with cannabidiol: it has been found in the hair of consumers of Spice-type mixtures. It acts on the same receptors as THC, the amount really present in a product remains unpredictable, and it is classified as a narcotic in France.
Receptors and activity
Target network
- Activates
The lower the cited value, the closer the target sits to JWH-007: one ring per factor of 100. A target with no measured value stays on the edge.

Pharmacology
JWH-007 is one of the naphthoylindoles from the laboratory of John W. Huffman, who prepared numerous cannabimimetic indoles to understand what the CB1 and CB2 receptors recognise. Its structure differs from that of JWH-018 only by a methyl at position 2 of the indole, and this is exactly the kind of minimal variation the series was intended to test: the structure-activity study published in 2005 by Huffman and colleagues systematically compared the 1-propyl and 1-pentyl naphthoylindoles with and without this methyl. The compound behaves as a cannabimimetic agonist: ChEMBL reports a Ki of 9.5 nM at CB1 from the 1994 article, and, in the rat, it substitutes for CP55,940 in drug discrimination (Wiley et al., 1998). As a benchmark in the same series, JWH-018 lies around 9 nM at CB1 and 2.9 nM at CB2 (Wiley et al., 2012). Nothing is published on TRPV1, GPR55, PPARγ or 5-HT1A, and there is no controlled study in humans: neither dose, tolerance nor dependence is characterised. What is documented in humans is limited to the detection of the molecule in the hair of chronic consumers of Spice-type mixtures, where two to six synthetic cannabinoids are found in the same segment (Hutter et al., 2012).

History
- Source
- An entirely synthetic molecule, absent from hemp and from any living organism. It figures among the synthetic cannabinoids sought in the hair of consumers of Spice-type mixtures (Hutter et al., 2012), and in the lists of the EUDA and of UNODC recording the synthetic cannabinoids reported (Zangani et al., 2020). None of this relates to hemp or to cannabidiol products.
Origin
Laboratory synthesis
No known biosynthetic pathway: the molecule is produced by no plant or living organism. It belongs solely to synthetic chemistry, described here by chemical class only.
Legal framework
- European Union
The substance is not listed in the Annex to Council Framework Decision 2004/757/JHA (consolidated version of 12 January 2026), which lists the new psychoactive substances controlled at European Union level; control is a matter for national law. It appears in the lists of the EUDA and of UNODC recording the synthetic cannabinoids reported (Zangani et al., 2020), which is monitoring and not control. It does not appear in the schedules of the 1971 Convention on Psychotropic Substances (green list of the INCB, 35th and 36th editions). France cites this molecule by name in annex IV of its list.
- France
JWH-007 is classified as a narcotic in France, and cited under its own name. The ANSM consolidated list (updated 16 February 2026) cites it in annex IV, under the entry « JWH-007 ou 1-pentyl-2-méthyl-3-(1-naphthoyl) indole », as an example (« notamment ») of the generic family of the « indol-3-yl methanones »: a substituent on the indole nitrogen of the alkyl, haloalkyl, halobenzyl, alkenyl, cycloalkylmethyl, cycloalkylethyl, methyl-oxane, 1-(N-methylpiperidin-2-yl)methyl or 2-(4-morpholinyl)ethyl type, and a naphthyl, benzyl, phenyl, cyclopropyl or adamantyl group on the carbon of the methanone bridge. This family was introduced into annex IV by the decree of 31 March 2017 (JORF of 6 April 2017), whose text, as re-read, already cites JWH-007. It is therefore not the clause on tetrahydrocannabinols (annex III since the decision of 6 February 2026) that applies. Production, possession, transfer, transport and use fall under the criminal law on narcotics.
