Oral dose ladder (Erowid)0
Erowid's dosage documentation for oral DOM[1] reports the following tiers:
- Threshold: 0.5-1 mg
- Light: 1-2 mg
- Common: 2-6 mg
- Strong: 6-10 mg
- Heavy: 8-12 mg
Onset 1 to 2 hours; duration 12 to 20 hours (longer at higher doses); residual effects 6 to 12 hours. The slow onset and very long duration make DOM particularly prone to accidental redosing before initial effects peak; this was a significant harm factor in its street use as "STP"
in the 1960s.Effects
