25B-NBOH Stats & Data

25B‑NBOH is active in the microgram range; inaccurate measurement (e.g., eyeballing powder) greatly increases overdose risk and should be avoided. NBx compounds (NBOH/NBOMe) have produced severe adverse effects including vasoconstriction, agitation, seizures, hyperthermia, and rhabdomyolysis in clinical case series; medical evaluation is warranted for symptoms like chest pain, blue/cold extremities, prolonged confusion, or seizure. Buccal/sublingual absorption is the primary active route; swallowing reduces effects variably, and redosing during a slow onset has led to accidental overdoses with related NBx. 25B‑NBOH has been mis-sold as ‘LSD’ (including in powder form, which is atypical for LSD); use multi-reagent testing and drug checking where available. Ehrlich reagent turns purple for indole lysergamides (e.g., LSD) but shows no color with NBOH/NBOMe; Hofmann/Marquis patterns can add context—however, reagent tests are screening tools, not definitive IDs. Bitter taste and localized oral numbing are commonly reported with NBx, but taste is not a reliable identification method and should not replace testing. Strong stimulatory combinations (e.g., with amphetamines or cocaine) elevate risks of hypertension and dangerous vasoconstriction beyond either drug alone. Tramadol lowers seizure threshold and has been repeatedly associated with seizures when combined with serotonergic psychedelics; avoid. Lithium has many consistent reports of severe adverse reactions, including seizures, when combined with classical psychedelics; given the similar 5‑HT2A agonism of NBOH compounds, this combination should be considered high‑risk. SSRIs often blunt psychedelic effects via receptor downregulation; they are not reliable ‘safety buffers’ and may complicate responses—avoid intentional mixing. Cannabis can unpredictably potentiate psychedelics and anxiety; titrate cautiously or avoid. Tolerance to 5‑HT2A agonists can be pronounced for days; allow at least 1–2 weeks between strong psychedelic sessions to reduce the urge to escalate dose. Seek immediate care for signs of hyperthermia (hot, confused, profuse sweating), chest pain, severe headache, seizure activity, or new neurologic deficits.
