Toxicity

NBOMe substances are frequently linked to severe toxicity and fatalities. Research on the NBOMe compound family has revealed their neurotoxic and cardiotoxic properties. Autonomic dysfunction, including vasoconstriction, hypertension, and tachycardia, is familiar with NBOMe compounds, often accompanied by hallucinations. Additionally, symptoms of toxidrome include agitation, seizure, hyperthermia, diaphoresis, hypertonia, rhabdomyolysis, and even death. Incidents of NBOMe intoxication often manifest signs of serotonin syndrome, with a higher likelihood of seizures than other psychedelics.
Sold as LSD on blotter papers, NBOMe and NBOH compounds can have a bitter taste and distinct safety profiles. Despite their high potency, recreational doses of LSD have shown minimal incidents of acute toxicity. Fatalities related to NBOMe ingestion suggest that many individuals unknowingly consumed the substance, believing it to be LSD, leading researchers to caution that “users familiar with LSD may mistakenly assume safety when ingesting NBOMe.”[6] While most deaths are attributed to the physical effects of the drug, there have been reports of fatalities due to self-harm and suicide under its influence.
Due to the limited documentation of NBOMe consumption, the long-term effects of the substance still need to be clarified. NBOMe compounds are not active orally[a] and are typically taken sublingually.: 3 Sublingual administration of NBOMes often results in tongue and mouth numbness followed by a metallic chemical taste, considered a critical distinguishing feature between NBOMe compounds and LSD by researchers.

Legality

Sweden:
In Sweden, 25H-NBOMe was included in the Narcotic Drugs Punishments Act under Swedish Schedule I (“substances, plant materials, and fungi which normally do not have medical use”) effective August 1, 2013. This edition was published by the Medical Products Agency (MPA) in regulation LVFS 2013:15, listed as 25H-NBOMe, and 2-(2,5-methoxyphenyl)-N-(2-methoxybenzyl)ethanamine.
United Kingdom:
The United Kingdom categorizes this substance as a Class A drug under the N-benzyl phenethylamine catch-all clause in the Misuse of Drugs Act 1971.
