7-ADD

7-ADD is an abbreviation used to label a product offered in the new psychoactive substance market. Its chemical identity has not been established in the published literature. A 2025 analytical study found that a sample sold as 7-ADD was not a synthetic cannabinoid, as its label suggested, but belonged to the cathinone class. The researchers did not further investigate that sample, so the specific compound remains unidentified.

Identification

The available evidence comes from a study that purchased online products advertised as synthetic cannabinoids and analysed them using gas chromatography–mass spectrometry and nuclear magnetic resonance spectroscopy. Two samples, including one labelled 7-ADD, were found to belong to a different substance class. The 7-ADD-labelled material was identified only as a cathinone derivative; its exact structure was not reported (Hübner and colleagues, 2025).

This finding shows that the product name alone does not reliably identify its chemical contents. Without independent analytical identification, 7-ADD cannot be regarded as the name of a confirmed molecule.

Pharmacology and reported effects

No compound-specific pharmacological data are available for a chemically defined substance called 7-ADD. Because the sample in the 2025 study was not structurally elucidated, it is not possible to assign it a receptor profile or describe its effects based on that paper.

It would therefore be misleading to provide a conventional stimulant or cathinone effect profile for 7-ADD. The term may refer to a product label rather than one reproducible chemical substance.

Toxicity and research limitations

No reliable human case series, metabolism study or toxicological profile has been published under the name 7-ADD. The analytical finding raises a broader concern about mislabelled products: a sample sold under one name may contain a substance from a different chemical class, with different effects and risks.

Until the identity of the material sold as 7-ADD is established through analytical testing, claims about its potency, duration, dependence potential or toxicity remain unsupported.
