I have never knowingly ingested any, not that i'd mind trying.
But one time in highschool, i believe I smoked a joint laced with some. When I was in high school it was pretty common to buy single joints for $2. It was equally common for guys to tell you you were buying laced joints so they could charge a dollar extra...lol. here was talk of joints laced with anything you could imagine: formaldehyde, cough syrup, shrooms, lsd, coke, fuck anything you could imagine that would make someone immature and ignorant willing to spend an extra dollar... lol but in hindsight, most were just weed...lol
Anyway, this one time i bought a "laced" joint, and it definately was laced with something. I smoked it at 7:30am just before my 8am woodshop class lol. I remember walking onto the campus after smoking it, and walking through tall grass. The thought went through my mind, while looking down, that I was a giant, or maybe a dinosaur, stomping down a forest of trees.
hen I got into shop class and lets just say that on a 50/50 chance, I gt very lucky. The band saw wasn't cutting my piece of wood properly. But, between the thought of the saw being on, and the sound of the other saws in the backgrund, I couldnt tell weather it was on or not just by looking at the blade, because it apeared to be moving. So to test it I touched the blade with my finger. Well I still have 10 full fingers, so like i said, i got lucky.
Anyway I havent heard anything about pcp in yearss, not even in sensationalist news stories, so good luck on your search, and hell if you find some pm me, id like to partake
