The Drug Enforcement Administration proposes placing five tryptamine hallucinogens, 4-hydroxy-N,N-diisopropyltryptamine (other names: 4-OH-DiPT; 3-(2-(diisopropylamino)ethyl)-1H-indol-4- ol), 5-methoxy-alpha-methyltryptamine (other names: 5-MeO-AMT; 1-(5- methoxy-1H-indol-3-yl)propan-2-amine), 5-methoxy-N-methyl-N- isopropyltryptamine (other names: 5-MeO-MiPT; N-(2-(5-methoxy-1H-indol- 3-yl)ethyl)-N-methylpropan-2-amine), 5-methoxy-N,N-diethyltryptamine (other names: 5-MeO-DET; N,N-diethyl-2-(5-methoxy-1H-indol-3- yl)ethanamine), and N,N-diisopropyltryptamine (other names: DiPT; N-(2- (1H-indol-3-yl)ethyl)-N-isopropylpropan-2-amine), including their salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible, in schedule I of the Controlled Substances Act. If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis with, or possess) or propose to handle these five specific tryptamine hallucinogens.
