I actually had a chance to try bath salts during that window when they were technically legal, not that I'm saying I've spent my life in the technically legal range of every substance I've ingested. I think I missed my chance to do acid legally by a little over forty years.
Am I endorsing bath salts? I don't think it'll drive you over the brink of insanity as long as you're not stupid about it. I hardly think that's a good reason to do anything though. For example, that also applies to holding your non-dominant hand in an open fire for five seconds.
So I highly endorse holding your non-dominant hand in an open fire for five seconds. It might be fun, I heard it is for some people, how will you know unless you try it? Meanwhile, the media is telling everyone that it'll give you Lupus instantly. Point is, don't let me or anyone else do your thinking for you.
"Thinking", by the way, is more likely to drive you over the brink of insanity than anything.
