Quick answer
4-AcO-DMT is typically detectable in urine for roughly 6–24 hours (specialised assay) after any use. It is not part of standard employment panels.
Not screened on standard employment panels.
Typical cutoff: Not on standard panels; requires a dedicated assay. It is metabolised to psilocin, so specialised psilocin testing may apply.

Ranges reflect typical published detection windows and vary with dose, frequency, body composition, hydration and the assay used.
Key details
4-AcO-DMT is a synthetic tryptamine that the body converts to psilocin, the active compound in psilocybin mushrooms. It is not part of standard employment panels.
Because it metabolises to psilocin, specialised testing that targets psilocin may detect it; routine panels will not.
Detection windows for tryptamines are short, typically under a day in urine.
How 4-AcO-DMT is tested
Not on standard panels; requires a dedicated assay. It is metabolised to psilocin, so specialised psilocin testing may apply. Screening immunoassays are presumptive — a non-negative screen is confirmed by GC-MS or LC-MS/MS at a lower cutoff before it is reported as positive. It is not part of the standard 5-, 10- or 12-panel or DOT tests.
Legal status
Not explicitly scheduled federally; treated as an analogue in many jurisdictions.
Frequently asked questions
How long does 4-aco-dmt stay in your system?
In urine, typical detection is roughly 6–24 hours (specialised assay). Hair can detect use for up to 90 days and saliva/blood windows are usually shorter.
Will 4-aco-dmt show up on a standard drug test?
No — 4-AcO-DMT is not part of the standard 5-, 10- or 12-panel or DOT tests. It would require a specialised or expanded assay.
How accurate are these detection windows?
They are typical ranges from published literature and assay documentation, not guarantees. Clearance depends on dose, frequency, metabolism and the specific test cutoff used.
