DMT is a Schedule I controlled substance in the United States, meaning it’s illegal to use recreationally. It’s known for producing intense hallucinations. DMT goes by many names, including Dimitri, fantasia, and the spirit molecule.

DMT is naturally found in some plant species and combined with other plants to produce a brew called ayahuasca, which is consumed in spiritual ceremonies in several South American cultures.

There’s also synthetic DMT, which comes in the form of a white, crystalline powder. This type of DMT is typically smoked or vaporized, though some snort or inject it.

People use DMT for the intense psychedelic trip that feels like an out-of-body experience. But a range of physical and mental side effects accompany this powerful trip, some of which can be pretty unpleasant.
