DiPT /ˈdɪpt/ or N,N-diisopropyltryptamine /ˌdˌsˌprpəlˈtrɪptəmn/ 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. It has been suggested that DiPT may have value to researchers of neurology due to its complex audio distorting effects.


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.

Hallucinogenic properties

General effects

Although DiPT's effects are primarily aural, some users have reported that at higher doses they noticed a lack of coordination or balance, confusion, and some users have reported minor visual distortions. Aside from these, the most prevalent non-auditory effect is inner ear pressure (which has been painful in some instances, for example when combined with MDMA). Unlike other psychedelics, users' set and setting doesn't seem to influence what is experienced.[citation needed]

Audio distortion

There is much speculation as to the nature of DiPT's aural distortion. At lower dosages, it has been reported to have an effect 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. [1]

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that there is no clear relationship between perceived pitch and actual pitch.[citation needed] Although recent unpublished research has examined the role of DiPT in hearing perception in rodent, it is not clear that the auditory effect is preserved in nonhuman species; this research indicates that DiPT does not produce effects similar to other tryptamine psychedelics such as DPT and 5-MeO-DMT in acoustic startle reflex paradigms. DiPT still remains widely unexplored.

Legal status

United Kingdom

As is the case with many PiHKAL and TiHKAL drugs, it is Class A in the UK, making it illegal to possess or use.

United States

DiPT is not scheduled at the federal level in the United States,[2] but it could be considered an analog of 5-MeO-DiPT, in which case purchase, sale, or possession could be prosecuted under the Federal Analog Act. Some of the people arrested in Operation Web Tryp were selling DiPT.


"DiPT (N,N-Diisopropyltryptamine)" is a Schedule I controlled substance in the state of Florida making it illegal to buy, sell, or possess in Florida.[3]
