The class-A drugs - powerful synthetic psychedelics similar to LSD - include 2C-1, 4-HO-DiPT and 5-Meo-DMT and are being made in "commercial labs", often in the US, which openly sell their products on the internet. Britain has outlawed all of these drugs but in the US the bulk of the so-called "research chemicals" are legal to manufacture, sell, possess and consume.
