Laws on research chemicals in the USA
The U.S. currently has no legislation which explicitly identifies individual research chemicals as scheduled. However the term ‘Research Chemical’ was specifically applied in an attempt to avoid prosecution under the Federal Analog Act (see History of Research Chemicals). Since a majority of research chemicals bear some functional and structural similarity to a scheduled chemical, they could theoretically be considered to be scheduled provided that intent for human consumption can be demonstrated. Precedent has already been set that vendors of research chemicals may be contravening this law (see Operation Web Tryp).
While those involved in distribution of research chemicals have been shown to be vulnerable, there are currently no known cases of prosecutions against individuals for possession of a controlled substance analogue. As a result the legality of mere possession of such chemicals remains a grey area, as it is unclear whether intent for human consumption is demonstrable.
