25C-NBOMe

25C-NBOMe, also known as NBOMe-2C-C, 2C-C-NBOMe, or Cimbi-82, is a psychedelic drug and derivative of the psychedelic phenethylamine 2C-C. It acts as a potent agonist of the 5-HT2A receptor, and has been studied in its C radiolabelled form as a potential ligand for mapping the distribution of 5-HT2A receptors in the brain, using positron emission tomography (PET). Multiple deaths have occurred from usage of 25C-NBOMe due to the ease of accidental overdose. The long-term toxic effects of the drug have not been researched. 25C-NBOMe was first described in the scientific literature by 2010. 25C-NBOMe is extremely potent and the effects of the drug increase greatly within a small window of dose adjustment. Overdose may occur at as little as double an average dose. With inaccurate dosing of street blotter paper, when mistaken for LSD, or when taken as a powder or liquid, this has resulted in multiple accidental deaths. One study has shown that 25C-NBOMe blotters have 'hotspots' of the drug and the dose is not evenly applied over the surface of the paper, which could lead to overdose. Sublingually, the threshold for the onset of hallucinogenic effects reportedly is about 100–250 μg, with mild effects at 250–450, strong effects at 450–800, and very strong effects over 800 μg.
