5-MeO-DALT or N,N-diallyl-5-methoxytryptamine is a psychedelic tryptamine first synthesized by Alexander Shulgin.


The full name of the chemical is N-allyl-N-[2-(5-methoxy-1H-indol-3-yl)ethyl]prop-2-en-1-amine. It is chemically related to the compounds 5-MeO-DPT and DALT.


The first material regarding the synthesis and effects of 5-MeO-DALT was sent from Alexander Shulgin to a researcher in May 2004, after which it was circulated online. In June 2004 5-MeO-DALT became available from internet research chemical vendors. In August 2004 the synthesis and effects of 5-MeO-DALT were published by Erowid.[1]


Doses ranging from 12–20 mg were tested by Alexander Shulgin's research group.[2]


There are numerous anecdotal reports of users consuming dosages far in excess of those tested by Alexander Shulgin,[citation needed] although there is no published literature on the toxicity of 5-MeO-DALT.

5-MeO-DALT has been known to directly contribute to the death of a popular businessman in the Cambridgeshire area.[3]

Drug prohibition laws[edit]

It is legal in the UK because the allyl group is not an alkyl group, which the law requires for a tryptamine to be illegal.


5-MeO-DALT became a controlled substance in Japan from April 2007, by amendment to the Pharmaceutical Affairs Law.[4]


Sveriges riksdag added 5-MeO-DALT to schedule I ("substances, plant materials and fungi which normally do not have medical use") as narcotics in Sweden as of May 1, 2012, published by Medical Products Agency in their regulation LVFS 2012:6 listed as 5-MeO-DALT N-allyl-N-[2-(5-metoxi-1H-indol-3-yl)etyl]-prop-2-en-1-amin.[5]
