N-Methyl-N-isopropyltryptamine

N-Methyl-N-isopropyltryptamine (MIPT) is a psychedelic tryptamine, closely related to DMT, DIPT and Miprocin.

Chemistry
MIPT base, unlike many other tryptamines in their freebase form, does not decompose rapidly in the presence of light in oxygen.

Dosage
10-25 mg is usually taken orally, with effects lasting 4-6 hours.

Effects
MIPT is said to emphasize psychedelic/entheogenic effects over sensory/hallucinogenic activity. Users report strong mental effects, but few perceptual alterations.

Legality
MiPT is unscheduled and unregulated in the United States, however its close similarity in structure and effects to DMT and DET could potentially subject possession and sale of MIPT to prosecution under the Federal Analog Act. This seems to be the tact the federal government is taking in the wake of the DEA's Operation Web Tryp. A series of Court Cases in the US involving the prosecution of several online vendors in ongoing as of 2004.
