5,N,N-trimethyltryptamine (5,N,N-TMT; 5-TMT) is a tryptamine derivative that is a psychedelic drug. It was first made in 1958 by E. H. Young. In animal experiments it was found to be in between DMT and 5-MeO-DMT in potency  which would suggest an active dosage for humans in the 20-60 mg range. Human psychoactivity for this compound has been claimed in reports on websites such as Erowid but has not been independently confirmed.
5,N,N-TMT is not scheduled at the federal level in the United States, but it could be considered an analog of 5-MeO-DMT, in which case, sales or possession intended for human consumption could be prosecuted under the Federal Analog Act.
