The problem is, you and tons of folk like you didn't read the fine print, because... who knows, ignorance? Fok ya all attitude of young? Even though all info is few clicks away at most.
It has been said 10 thousand times here and everywhere else, including quite a few posts by me - just don't do any mind altering drugs if you are not balanced +-happy person. There is no clear definition or dividing line, each of us is unique and should know how stable/unstable they are, if they have unresolved long term issues and so on. If folks can't be even honest in such things with themselves, well, life will be a tough walk in many aspects thats for sure.
For all those folks, if you do such things, you take tremendous risk, you may end up off better despite issues, but that's your Russian roulette with your own mind, don't complain that you risked massively and lost a huge gamble. These cases are not reference, unless say 50% of US population is by default anxious.
