DiPT (commonly pronounced /ˈdɪpti/) or diisopropyltryptamine (/ˌdaɪaɪsoʊˌproʊpəlˈtrɪptəmiːn/) 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 audial. 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 audial, some users have reported that at higher doses they noticed a lack of coordination or balance, and some users have reported minor visual hallucinations. Besides from these, the most prevalent non-auditory effect is inner ear pressure (which has been painful in some instances). Some users do report intense entheogenic effects along with sound distortion. The users' set and setting seem to influence what is experienced.

Audio Distortion

There is much speculation as to the nature of DiPT's audial distortion. At lower dosages, it has been reported to have an effect not unlike a flanging, or a phase shift. At medium and higher dosages, the effect DiPT has is disputed, and can differ from person to person. By far the most common result of higher dosages is a radical shift downward in perceived pitch. This shift tends to be nonlinear, in that the shift downwards varies based on the initial pitch. This can produce bizarre sounds and can 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.[citation needed] Research in this and related areas still remains widely unexplored, and will most likely remain so due to DiPT's legal status.

Health Concerns

The most widespread health problem attributed to DiPT is tinnitus, or ear-ringing. These symptoms may only last for the duration of the experience, or may persist for weeks or even months. Some users have even reported that their tinnitus was a permanent effect, although this remains rare.[citation needed]

Legal status

DiPT is not explicitly scheduled, but possession can most likely still be prosecuted under the Analog Act, as demonstrated by July, 2004's Operation Web Tryp. 5-MeO-DiPT is schedule I as of April 2003.
