It deserves more study -- the idea of using much more reasonable doses as a form of anti-depressant is interesting.
However, it's probably not magic, just in the same way MJ oil is probably not a cure for cancer. They, of course, don't list the many other discoveries made by scientists not on LSD. The "studies" really aren't terribly disciplined... I grant you because of its illegal status, but...
Given my personal experience with LSD devotees, I'm extremely skeptical of the benefits. The general trend is more towards extreme narcissism than enlightenment, and I would advise people to stay away from the stuff.
