N,N-Dipropyltryptamine (DPT) is a psychedelic entheogen belonging to the tryptamine family. Use as a designer drug has been documented by law enforcement officials since as early as 1968.[1] However, potential therapeutic use was not investigated until the 1970s.[2] It is found either as a crystalline hydrochloride salt or as an oily or crystalline base. It has not been found to occur endogenously. It is a close structural homologue of dimethyltryptamine and diethyltryptamine.

Frequent physical effects are nausea, numbness of the tongue or throat, and pupil dilation.


Studies on rodents have found that the effectiveness with which a selective 5-HT2A receptor antagonist blocks the behavioral actions of this compound strongly suggests that the 5-HT2A receptor is an important site of action for DPT, but the modulatory actions of a 5-HT1A receptor antagonist also imply a 5-HT1A-mediated component to the actions of DPT.[3]


DPT changes Ehrlich's reagent violet and causes the marquis reagent to turn yellow.[4]

Psychedelic properties

While dipropyltryptamine is chemically similar to dimethyltryptamine (DMT), its psychoactive effects are markedly different.[5]

Side effects

Negative side effects of human consumption of this drug may include increased heart rate, dizziness, anxiety, panic, confusion, paranoia, delusions, seizure (uncommon) and nausea. The use of dipropyltryptamine has been implicated in at least one death due to seizures,[6] although details are lacking and the drug has not officially been established as the sole cause of death.

Religious use

DPT is used as a religious sacrament by the Temple of the True Inner Light, a New York City offshoot of the Native American Church. The Temple believes DPT and other entheogens are physical manifestations of God.[7]
