The hallucinogenic and entheogenic effects of 5-MeO-DiPT are believed to be primarily generated through 5-HT2A receptor agonism. However, it’s worth noting that additional mechanisms of action, such as monoamine oxidase inhibition (MAOI), may also play a role. Notably, 5-MeO-DiPT exhibits the strongest receptor binding affinity for the 5-HT1A receptor.

Furthermore, it’s important to highlight that 5-MeO-DiPT has been found to be neurotoxic in rats.


Excessive doses of 5-MeO-DiPT have led to clinical intoxication, manifesting as symptoms like nausea, vomiting, agitation, hypotension, mydriasis, tachycardia, and hallucinations, particularly in young adults. Several cases of overdose can be linked to the drug’s extended onset of action. First-time users, unacquainted with the substance, sometimes administered a second dose when they initially felt no effects. In one case, a young man experienced rhabdomyolysis and renal failure, while another individual tragically passed away 3 4 hours following an apparent rectal overdose. It’s noteworthy that at least one fatality has been associated with the consumption of 5-MeO-DiPT.

Drug prohibition laws

Here is the legal status of 5-MeO-DiPT in various countries:

  1. China: 5-MeO-DiPT became a controlled substance in China as of October 2015.
  2. Denmark: It has been illegal in Denmark since February 2004.
  3. Germany: The substance was deemed illegal in Germany since September 1999.
  4. Greece: 5-MeO-DiPT has been illegal in Greece since February 2003.
  5. Japan: It became illegal in Japan in April 2005.
  6. Singapore: 5-MeO-DiPT was declared illegal in Singapore in early 2006.
  7. Sweden: The health ministry of Sweden (Sveriges riksdags Statens folkhälsoinstitut) classified 5-MeO-DiPT as a “health hazard” under the Act on the Prohibition of Certain Goods Dangerous to Health (Lagen om förbud mot vissa hälsofarliga varor) as of October 1, 2004. It is listed as 5-metoxi-N,N-diisopropyltryptamin (5-MeO-DIPT), making it illegal to sell or possess.
  8. United States: In the United States, the DEA added both 5-MeO-DiPT and alpha-methyltryptamine (AMT) to Schedule I of the Controlled Substances Act on April 4, 2003, using “emergency scheduling” procedures. These substances were officially placed into Schedule I on September 29, 2004. Prior to its prohibition in the U.S., 5-MeO-DiPT was sold online, along with psychoactive analogues like DiPT and DPT, neither of which had been expressly outlawed at the time.
