What is DMT?

DMT (chemical name dimethyltriptamine) is a hallucinogenic drug which is similar to LSD though its effects are more powerful. It has been used in spiritual shamanistic rituals in South America for centuries.


DMT is usually seen as a yellow, orange or pinky powder or crystals. It is less available than other hallucinogens such as LSD, and costs roughly £25 for a wrap containing an eighth to half a gram.

Method of use

DMT can be injected, smoked or sniffed and the effects often come on quickly but are short-lived: rarely lasting more than an hour.


The main effect of DMT is to produce hallucinations and distortions of time, space, sound and colour. Hallucinations may become intense and frightening and there may be flashbacks some time after using the drug. Such negative effects can often be calmed by reassuring the user that they are only temporary.

The law

DMT is listed as a hallucinogen under the Misuse of Drugs Act and is classified as a Class A drug.

The maximum penalty for possession is seven years in jail and/or an unlimited fine.

The maximum penalty for supply is life imprisonment, a fine or both.
