25I-NBOMe, for also being called as 2C-I-NBOMe, has its chemical name of 2-(4-iodo-2,5-dimethoxyphenyl)-N-[(2-methoxyphenyl)methyl]ethanamine. This chemical is a derivative of the phenethylamine psychedelic 2C-I by substitution on the amine with a 2-methoxybenzyl (BOMe) group. While you certainly don’t have to remember the chemical compound, you should know the effects of this deadly poison.
25I-NBOMe is a very new substance, with little known about its pharmacological or behavioural risks. The LD50 (median lethal dose) is not known. Some pharmacological deaths have been attributed to 25I-NBOMe overdose. The product is made without any form of quality control and cross contamination with other manufactured chemical products.
