I've definitely smoked weed laced with PCP before. One of the reasons I'm glad weed's gonna be legal (hopefully everywhere soon) so people know what they're getting. Nothing wrong with a PCP trip honestly but if you don't see it coming it's a bitch like being slipped a mickey.
PCP is a tranquilizer, so I imagine your brain is getting put into a semi-sleep, semi-conscious state, making you behave as if you're acting out a dream.
Yeah up until the 60s it was used as a human anesthetic much like special K is still used for cats. If you know vets or have ever been in a K hole it's basically a stronger version of that but you have a lot more energy than Ketamine. Best description I can give was when I was sober and my girlfriend at the time smoked some laced marijuana and freaked out at my work because she could see inside her own eyes when she closed her eyes.. that was about the most coherent thing I ever got and the rest was just jiberish. That's the one time I ever just left work with the door locked for an hour to help her out knowing that I'd probably get fired. If you're looking for something that'll put you in a dream state, snort ketamine or smoke DMT.
It's the 'and possessed by demons' part that gets me. Whoever took this video is as crazy as the person in it, but in a completely different way. I respect that.
The Youtube description and comments are really something. People seem to think she's demon possessed and that dropping PCP has nothing to do with her actions.
