"research chemicals", as they are euphemistically known, are synthesised by commercial labs, often based in the US, which openly sell their products

Designer drugs are powerful synthetic psychedelics from the same chemical families as LSD, magic mushrooms and mescaline. They are too new to have enticing street names; instead their lengthy chemical names are shortened to abbreviations such as 2C-I, 4-HO-DiPT, and 5-Meo-DMT. Unlike ecstasy, methamphetamine or other synthetic recreational drugs, the new compounds are not made in illicit factories or backroom kitchen laboratories. Instead, "research chemicals", as they are euphemistically known, are synthesised by commercial labs, often based in the US, which openly sell their products on the internet.
