A very potent hallucinogenic drug of the Phenethylamine class, related to 2C-B,2C-E and Mescaline. It was synthesised by Alexander Shulgin. It is a schedule 1 drug in the US, a schedule 3 drug in Canada and a Class A drug in the UK. It is noted to produce very intense hallucinations that can last for 24 hours. The amount required to overdose is very low, and people have reported overdoses after 12mg orally.
