The Drug Enforcement Administration recently classified U-47700 as a Schedule I substance, making it illegal. That designation came after the teen boy is alleged to have bought and distributed the drug, however. Additionally, the drug is not illegal per Utah law. In light of that, prosecutors will have to prove the drug the teen boy allegedly distributed is a controlled substance analog, Cassell said. To classify as a controlled substance analog, the drug has to have a similar chemical nature to, or have the same effects of, a regular controlled substance.
prosecutors are charged with proving charges are under controlled substance analog act
