If you look into the statistics, I think you'll find that most of the cases where LSD has triggered other issues, the unfortunates tend to be under the age of 25 (it seems that most of the neurochemical issues that don't play well with acid manifest in the early 20s for most people).
I agree that LSD will almost certainly cause a life changing experience, and that such experiences are "not always roses for all", however, I do believe that life changing experiences are, in general, good things if taken with proper perspective. Again, YMMV.
I kind of resent your statement that I've fried my brain - I think that anyone who knows me would disagree with that assertion, but I understand that you're presenting the perspective of someone who has had a bad experience (or who knows someone who has had a bad experience). Any chance you'd like to discuss the motivation for your viewpoint further? I'm very interested in more data on the subject!
In any case, my apologies if I have offended; my intent was to share my experience.
I'll emphasize again that anyone considering taking any drugs should do some research first (erowid.org presents both the good and the bad), and should know themselves well before experimenting.
I truly hope you'll share some more about your experience(s). Thanks!
