I believe that eventually, you always come out stronger, but not necessarily immediately. (I also believe that holds true for almost any traumatic experience, not just drug related.)

I found a very well written answer to a question on Yahoo! Answers, the question was about THC but the answer is about psychedelics in general. "I have been convinced that I was broken beyond repair more times than I can count. The truth is that these things will make you wicked tough, the complete opposite of damaged. If you can handle sh*t like this, everyday life problems are much less likely to throw you off your center."

It's probably true. Nothing gives you more perspective on life. ("A drug person can learn to cope with things like seeing their dead grandmother crawling up their leg with a knife in her teeth."  )
