Methylallyltryptamine
Methylallyltryptamine, also known as N-methyl-N-allyltryptamine, is a lesser-known psychedelic drug from the tryptamine family. It is a novel compound with very little history of human use. It is closely related to methylpropyltryptamine. The drug has been sold online as a designer drug. Very little information on the pharmacology or toxicity of MALT is available.Use and effects
MALT was not included in Alexander Shulgin's 1997 book TiHKAL. However, years after the book's publication, he described MALT as having important unexplored potential as a psychedelic drug. Subsequently, MALT was encountered as a novel designer drug. It has been reported to have been used at doses of 25 to 50mg via routes including oral, smoking, or vaping. The drug's effects have been described as comparable to those of methylpropyltryptamine but less pronounced.Interactions
Pharmacology

Analogues
s of MALT include 4-HO-MALT, 4-AcO-MALT, 5-MeO-MALT, diallyltryptamine, methylpropyltryptamine, and methylisopropyltryptamine, among others.History
MALT was first described in the scientific literature by Niels Jensen of the University of Göttingen by 2004. The drug was subsequently first encountered as a novel designer drug by 2018.Legal status
MALT is not explicitly scheduled in any countries; however, it could be considered a psychoactive substance under the United Kingdom Psychoactive Substances Act, which requires the prosecutor to prove that the substance is psychoactive in order for a person to be charged with an offense. It could also be considered a structural analogue of a scheduled substance under the United States Federal Analogue Act due to its similarity to scheduled tryptamines. It is not a controlled substance in Canada as of 2025.
