    5-HT2C receptor agonist
    5-HT2B receptor agonist (cardiotoxic)

    History & Culture

    25iP-NBOMe emerged as a novel designer drug and was first documented in the scientific literature around 2014. Like other members of the NBOMe series, it represents an N-benzyl modification of an existing 2C-x compound—in this case, 2C-iP. The substance remains relatively obscure compared to more widely encountered NBOMe compounds such as 25I-NBOMe or 25C-NBOMe, with limited information available regarding its history of human use or cultural significance.

    Tolerance & Pharmacokinetics

    drugs.wiki
    Half-Life
    Formal data lacking; modeling of related NBOMes places plasma t½ roughly 2–4 h, with subjective effects persisting beyond plasma clearance.
    Addiction Potential
    Very low physical dependence; mild psychological craving reported by some users for the stimulating euphoria.

    Tolerance Decay

    Full tolerance 0h Half tolerance 7d Baseline ~14d

    Acute tolerance develops rapidly after a single strong session (typical of 5‑HT2A agonists). Substantial tolerance persists for days and decays over 1–3+ weeks; precise kinetics for 25iP‑NBOMe are not characterized. Cross‑tolerance with other psychedelics is expected but unquantified; ratios are heuristic. Data quality relies on class‑level evidence and user reports, not controlled human studies.

    Legal Status

    Country Status Notes
    United Kingdom Class A Controlled under the Misuse of Drugs Act 1971 through the N-benzylphenethylamine catch-all clause, which covers NBOMe compounds as a structural class. Class A substances carry the most severe penalties, with possession punishable by up to 7 years imprisonment and supply by up to life imprisonment.

    Harm Reduction

    drugs.wiki

    • Microgram potency; never eyeball. Use a 0.001 g (or better) scale and volumetric dosing. NBOMe powders are too potent for typical scales; uneven blotter loading is commonly reported.

    • Do not assume oral inactivity. For NBOMes, oral bioavailability can be unreliable rather than absent; delayed effects have led to hazardous redosing. Prefer buccal administration if using at all.

    • Strong peripheral vasoconstriction and sympathomimetic toxicity have been repeatedly reported with NBOMes (tachycardia, hypertension, cold or numb extremities). Risk increases steeply ≥1 mg.

    • Misrepresentation on LSD-style blotter is common; NBOMe tabs are typically bitter/metallic and can numb the mouth. Test blotters: Ehrlich/Hofmann positive suggests lysergamide; NBOMes do not react with Ehrlich and show distinct Marquis reactions.

    • Avoid combinations with stimulants, MAOIs, DXM, or tramadol. These increase risks of hypertension, hyperthermia, seizures, and serotonin toxicity.

    • Re-dosing strongly increases unpredictability, body-load, and adverse events; wait at least 3 h before concluding inactivity when identity is uncertain.

    • Severe agitation, seizures, or hyperthermia require urgent medical care. First-line in hospital is supportive care with benzodiazepines and cooling; mention suspected NBOMe to clinicians.

    • Nasal dosing increases speed of onset and adverse body-load; irritation and pronounced vasoconstriction are common. Avoid dry powder insufflation.

    • Keep the environment cool, avoid prolonged physical exertion, and sip fluids with electrolytes to mitigate hyperthermia risk; do not overhydrate.

    • People with cardiovascular disease, Raynaud’s phenomenon, or seizure history should avoid the NBOMe class entirely due to elevated risk.

    • Distinguish from LSD: LSD blotter is typically nearly tasteless and fluoresces under UV; NBOMe blotters are often bitter/metallic and may not fluoresce. Always rely on reagents/drug checking, not taste alone.
