What is 4-AcO-DMT?

4-AcO-DMT, also called O-acetylpsilocin, psilacetin, and psilocetin, is a synthetic psychedelic substance. The compound is structurally similar to magic mushrooms' primary hallucinogenic compound, psilocybin. Like psilocybin, 4-AcO-DMT acts as a prodrug to psilocin, which means that the body converts the compound into psilocin after ingestion. This function is incredibly valuable as psilocin is the active tryptamine that exerts magic mushrooms’ psychedelic effects upon ingestion.

This article comprehensively explains 4-AcO-DMT, focusing on its chemical properties, dosage, psychedelic effects, lab testing, and legality.

4-AcO-DMT Discovery

Albert Hofmann and Franz Troxler synthesized 4-AcO-DMT in 1963 while researching psilocin analogs. However, they did not examine psychoactive properties at that time.  In 1999, medicinal chemist David E. Nichols highlighted its promise as a more cost-effective substitute for psilocybin in pharmacological studies. Following its emergence in the online research chemical market in the 2010s, anecdotal accounts of its recreational use began to emerge.

Chemical Profile and Synthesis

4-AcO-DMT, chemically known as 4-Acetoxy-N, N-dimethyltryptamine, is a synthetic compound under the hallucinogen category. The '4-AcO' in its name refers to a 4-acetoxy group attached to the nitrogen atom of the tryptamine backbone.

The chemical structure of 4-AcO-DMT, with this 4-acetoxy group, differentiates it from psilocybin, which contains a 4-phosphoryloxy group. Despite the differences, both compounds share a similar indole ring structure that is typical of tryptamines. This structural similarity underpins their comparable pharmacological effects, as scientists believe both to be prodrugs of psilocin in the human body. 

Synthesizing 4-AcO-DMT in a laboratory setting typically involves acetylating psilocin, although scientists can also synthesize it from other tryptamine precursors. The process usually requires advanced knowledge of organic chemistry and access to specific reagents and equipment. The method can vary but typically involves a series of chemical reactions introducing the acetoxy group into the tryptamine structure.

Psychoactive Effects 

4-AcO-DMT’s tryptamine structure gives it a range of mind-altering effects comparable to classic psychedelics, particularly psilocybin. 

‍

Sensory Enhancements

• Explorers often report enhanced colors, geometric patterns, and visual distortions or hallucinations. These can range from subtle enhancements in color and texture to complex, shifting patterns and fractal-like images.

• Sounds may seem more distinct or take on a different quality, such as echoing. Music can feel more emotionally profound. 

• Some people experience a heightened sense of touch, often described as more immersive.

‍

Emotional Shifts

4-AcO-DMT can induce a wide range of emotional states, from euphoria and bliss to introspection and empathy. In some cases, it can also lead to challenging experiences, such as anxiety or introspective thoughts. There's often an increased feeling of openness and connectedness with others, similar to MDMA but less intense.

‍

Cognitive Alterations

Users often report changes in their patterns, including nonlinear thinking, a sense of interconnectedness, or profound philosophical insights. Time may slow down, speed up, or become irrelevant.

Comparing 4-AcO-DMT  with Psilocybin

4-AcO-DMT’s effects are largely similar to psilocybin due to their shared metabolic pathway to psilocin. 

However, some people report subtle differences.

The onset and duration of effects can differ slightly depending on the route of administration and individual metabolism.  Some people report that 4-AcO-DMT has a smoother onset than psilocybin, potentially leading to a more gentle experience. The emotional and cognitive effects can be very subjective and variable between individuals, but both substances are known for their potential to induce profound and meaningful experiences.

Dosage and Administration Methods

According to retired police sergeant Keith Graves’ law enforcement guide, the typical  4-AcO-DMT dosage ranges are:

• Mild: 5-10 mg
• Standard: 10-25 mg
• Potent: 25-40 mg
• Extreme: 40+ mg

Administration Methods

• Oral Ingestion: Most people ingest 4-AcO-DMT through it as pills, capsules, or powders dissolved in liquid. The onset of effects typically takes 20-40 minutes, with the experience peaking around 2-3 hours and lasting up to 6 hours.
• Insufflation (Snorting): Snorting 4-AcO-DMT leads to a quicker onset of effects. This method may make the experience's overall duration shorter and more potent. 

Less common methods include vaporization and intravenous administration, which may have increased risks and difficulty controlling the dosage.
