25dimethoxy4iodoamphetamine

25-dimethoxy-4-iodo-NBOMe, commonly referred to as 25I-NBOMe, is a synthetic psychedelic in the NBOMe family. It is a substituted phenethylamine believed to act as a highly potent agonist at the serotonin 5-HT2A receptor, producing strong alterations in perception, mood, and cognition. The chemical structure features methoxy groups on the aromatic ring, a 4-iodo substitution, and a N-(2-methoxybenzyl)ethanamine side chain.

Pharmacology and effects are characterized by significant potency, with users reporting intense visual effects, cognitive shifts, and heightened autonomic activity. The experience can vary greatly between individuals and is influenced by dose, route of administration, and interactions with other substances. Adverse reactions may include severe agitation, vasoconstriction, hypertension, tachycardia, hyperthermia, seizures, and, in some cases, life-threatening complications. The potential for unpredictable effects and difficulty in controlling onset and duration contribute to safety concerns.

History and use: NBOMe compounds emerged in the early 2010s as research chemicals marketed online and distributed as legal or “legal-high” alternatives to other psychedelics. 25I-NBOMe and related substances have been encountered in a variety of forms, including blotter paper and powders. Their potency and variability have led to a substantial number of hospitalizations and fatalities in some regions.

Legal status: NBOMe compounds, including 25I-NBOMe, are controlled substances in many countries and are illegal to manufacture, distribute, or possess outside of authorized research or medical contexts. Jurisdictional classifications vary, but they are commonly placed in high-schedule categories.

Detection and testing: Specialized laboratory methods (such as GC-MS or LC-MS/MS) are required to confirm NBOMe presence. They are not reliably detected by many standard immunoassay drug tests, complicating routine screening.
