4-Propionoxy-N,N-dimethyltryptamine (4-PrO-DMT, or O-Propionylpsilocin) is a synthetic psychedelic drug from the tryptamine family with psychedelic effects, and is believed to act as a prodrug for psilocin. It produces a head-twitch response in mice. It has been sold online as a designer drug since May 2019. It was first identified as a new psychoactive substance in Sweden, in July 2019. A number of related derivatives have been synthesized as prodrugs of psilocin for medical applications.
