Diisopropyltryptamine


Diisopropyltryptamine is a psychedelic hallucinogenic drug of the tryptamine family that has a unique effect. While the majority of hallucinogens affect the visual sense, DiPT is primarily aural.

Hallucinogenic properties

DiPT's effects are primarily aural. At lower doses, Alexander Shulgin reported effects similar to a flanging or a phase shift. At medium and higher dosages, the effect of DiPT is typically a radical shift downward in perceived pitch. This shift tends to be nonlinear, in that the shift downwards varies in relation to the initial pitch. This can produce bizarre sounds and render music disharmonious. There has been an experiment involving subjects with perfect pitch, the goal of which was to determine whether the pitch difference is truly distortive or linear, the results of which indicated that there is no clear relationship between perceived pitch and actual pitch. Aside from these, the most prevalent non-auditory effect is inner ear pressure.

Chemistry

DiPT is a derivative of tryptamine formed by substituting isopropyl groups for the two hydrogen atoms attached to the non-aromatic nitrogen atom in the tryptamine molecule.
