Imagine someone getting addicted to krokodil, then doing angel dust and going berzerker, almost like a George Romero zombie.. oh and they would have AIDS of course. Here is a question, do you think if you showed a monkey(s) how to do drugs, then keep giving him drugs, that the result would be similar to humans? I've done some drugs, but I can't fathom why one would shoot up heroin in a blown vein, or let their flesh rot away.. is it society or have people been doing this type of thing since the beginning?
