25H-NBOMe
Dosage & Duration
Duration
Subjective Effects
Reagent Testing
Expected colorimetric results for common reagent tests. Colors show reaction change over 1–2 minutes.
Pharmacology
Dangerous
Highest riskThese combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.
Unsafe
AvoidThere is considerable risk of physical harm when taking these combinations, they should be avoided where possible.

Use cautionThese combinations are not usually physically harmful, but may produce undesirable effects, such as physical discomfort or overstimulation. Extreme use may cause physical health issues. Synergistic effects may be unpredictable. Care should be taken when choosing to use this combination.
Tolerance
Harm Potential
Addiction & Dependence
Psychological
LowHas shown reinforcing effects in rodent studies, including conditioned place preference and self-administration, suggesting some potential for psychological reinforcement.
Toxicity
Suspected vasoconstrictive properties may pose risks at high doses; the extent of cardiovascular danger in humans remains poorly characterized.
