I smoked alpha pvp in a transit home in Saint Petersburg with some Georgian immigrants thinking it was meth, It made me really really high, and I spent the whole next day crying. I suspect this is a pretty popular drug in Russia.
Unfortunately, yes. I lost friend to it ("alpha"). He is technically alive, but with completely ruined physics.
I've thought, that only opiates could be so destructive, oh, man, I was wrong :-(
