Is angel dust or PCP the most dangerous drug?

Working in law enforcement I've see some crazy things. I wouldn't disagree with anyone saying its the most destructive drug. I've seen a man beating the $#%! Out of a tree. Bark had came off the tree and the meat off his knuckles and fingers. Tazed him and nothing happened it was like we weren't even there. As for most powerful I would have to say meth is most powerful. Much stronger than heroine. Keeps you awake, halucinations and itching of the skin which causes people to scratch themselves. In the course of 5 years I seen a HS qaurterback go from college bound to nearly dead. At 23 he looked roughly 35-40 years old and sadly it took his life at 25.
