I started doing 2C's in late 99, and 2C-B was the first one I ever came across. It has been illegal in the US for awhile but it was legal in the EU until the early 2000s and was easily available online (although the RC scene of 10 years ago is nothing like the scene today). It disappeared for awhile but it is certainly back on the scene now and has been for many years.. gotta love the global economy
Since I'm reminiscing, back before ketamine was scheduled in 99 you could get kilos shipped to your door for a few hundred dollars. 99 or 2000 was the year GHB got scheduled as well, and all the suppliers of GHB switched to sending kits to make your own, you would get GBL and sodium hydroxide in the same package..
Then RC's started getting more popular and a couple kids died doing 2C-T-7 and that got scheduled too.
Also I remember when Methylone first him the scene in 2002 it used to be ridiculously expensive, it cost more then buying MDMA would cost (gram for gram)
