DPT is also known as N,N-dipropyltryptamine, the Light, and N,N-DPT. This close cousin to DMT was first synthesized in the 1950s and tested in animals in the 1960s. According to Wang and Chen (2007), it is a psychedelic tryptamine that “is found either as a crystalline hydrochloride salt or as an oily or crystalline base”.

In the 1970s, it was studied as a possible treatment for alcoholism and in DPT-assisted psychotherapy for terminal cancer patients. Soskin, Grof, and Richards (1973) reported that their research study participants experienced “intensification of emotions, self-exploration at deeper levels of the psyche, recovery of emotionally relevant positive or negative memories, and enhanced insight into personal dynamics”.

In the 1980s, the Temple of the True Inner Light began using DPT as a sacrament. Pauli (1997) explained that “DPT ingestion, according to the Temple, allows direct communication with spirit forms and this communication provides the source of their theology”.

In recent years, DPT has been found on the illicit drug market (DEA, 2005).

Side Effects & Adverse Reactions:

Negative effects that have been reported include:

Remember, research chemicals are experimental chemicals that are not approved for human consumption. This is because not enough data exists currently about their effects in humans. Although some people are willing to ingest research chemicals, it is unreasonable to assume that they are in any way safe to use recreationally.


In 2001, a man was rushed to the emergency room and put into intensive care after ingesting a substance reported to be DPT. Altough he survived the experience, he reported numerous negative effects such as seizures, high heart rate, and a severe drop in blood potassium levels (Erowid).
