N,N-Dipropyltryptamine (DPT, also known as "The Light") is a psychedelicdrug belonging to the tryptamine family, first reported in 1973.[1] It is found either as its crystallinehydrochloridesalt or as an oily or crystalline base. It has not been found to occur naturally.
Studies on rodents have found that the effectiveness with which a selective 5-HT2A receptorantagonist blocks the behavioral actions of this compound strongly suggest 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.[2]
While dipropyltryptamine is chemically similar to dimethyltryptamine (DMT), its psychoactive effects are markedly different.[4]
The most prominent features of the DPT experience are increased significance or intensity of music, colors take on a new intensity or appearance, the body may have a buzz or vibratory feeling, a pleasant sensation of warmth, complete ego loss, apparitions of faces.[citation needed]
While seeing other beings under the influence of DPT may occasionally occur, the perspective is more as an observer or watcher, as contrasted to the more personal real-feeling entity contact reported with DMT.[5]
Also sometimes reported is a loss of ego boundary; for example, the boundary between the self and a table may not be easy to distinguish. Difficulty distinguishing other boundaries is common as well. For example, different colors may be difficult to distinguish. Other sensory input may also become blended. This is distinct from synaesthesia.[citation needed]
A user may also encounter the feeling of experiencing the life of someone else, or having had all possible experiences simultaneously. One may have the experience of seeing the universe from different locations in space and time.[citation needed]
Visuals are often geometric, wavy, and/or spiraled. Other visual distortions and hallucinations tend to be experienced in the peripheral vision. The self or the environment may take on a stylized cartoon-like look or feel. Pleasant flashes of light and sparkles are also common.[citation needed]
