Here's the specific piece from Cowboy Mac's link
...in December 2001, the government banned three new designer drugs, BZP, TFMPP and 2C-I;....
There's also the
Drugs of Dependance regulations covering analogues of which 2C-I would fall into several classes. So tight is this piece of legislation, that 1/2 of the commonly made chemicals in Uni labs would according to this legislation be illegal. My Chem lecturers just couldn't believe it.
There is a drug which has recently become available as a research chem which is similar to MDMA in structure and produces similar but milder effects. This chem is known as IAP (1-(5-indanyl)-2-aminopropane, another of Dr David Nicoles inventions in his search for a non-neurotoxic MDMA mimicking mind tool. IAP would also fall under the analogues/homologues bill, but if your research didn't involve human consumption it
should be possible to legally obtain it.
There are a couple of other research chemicals currently being whispered about. One shows particular promise as a rec drug, but at present I'm not about to mention what these chems are due to a general request being made on another, rather obscure board.
As soon as these chemicals show promise they are banned, so obviously the clandestine discoverers would at least like to see the word first spread via the selected underground. This way massive stockpiles of legal chemicals be obtained and probably also a large ready to go supply of the drug, before the world is turned on.....stay tuned, one of these chems may rock the world
