^^^ IMO, and I was younger and had less of an experience with many of the other wonderful substances I have since touched and fondled, but for eliminating mental problems, no other drug (well, K helps too) can eliminate all mental anguish in just a few short puffs. Of course, PCP is harder to control, dosage wise, than most other drugs; and many people would prefer the bliss of opiates, since they are much more easily regulated (even street H). Though, if you want to escape, PCP is the DOC.
Of course, studies have shown PCP to be one of the few drugs that may cause serious, and relatively quick (less times than many other drugs), strange brain activity (damage?).
Oh well, I do miss it. But alas, PCP isn't the type of drug one can hide when used. Not, "hey, let's go to XXX and smoke some diesel (strangely enough, dust was diesel [1988-1991] before H became being referred to diesel, at least in my part of the woods--which is NYC area)."
