I just typed a rather long reply to the thread, and the entire reply was lost because I was logged out for some reason while trying to submit the reply
This somewhat demotivates me from retyping the long reply, but I'll raise the most important points again.
When I asked, "were you attracted to RCs because of their legality", I was really asking "were you attracted to RCs because of their availability" - with legality of course tying into availability, and keeping in mind that I'm posing from a US viewpoint where most RCs are still legal.
Most people have to be introduced somehow to a new experience. The first time your had alcohol might have been at a party where it was served. No one ever introduced me to the idea of psychedelics. I have a small group of friends and we rarely even drink alcohol much less do anything else - so when I decided to explore further after my first (self-initiated) experience with DXM, I started with Google searches such as "legal highs" because I knew that none of my friends would know where to get any of your classic drugs like weed or LSD (and I did ask some of them, and others I knew well enough not to ask).
Those Google searches eventually led me to order 2C-I from a website. Finding new sites is a lot easier after you've found the first one - I was now "in the know". To use a computer science term, I had managed to bootstrap myself.
To wrap this up - I'm reminded of an essay I read a few months ago about MDMA (one of the "illegals" that I would like to try someday, compared to the "legal" methylone). MDMA was legal in the US through the mid-80s, and at one point was so prevalent in Dallas dance clubs that one could buy it with a credit card from the bartender.
