Mike Tyson said this quote
“ Burning cocaine is the worst smell in the world. It smells like burning plastic and rat poison combined. A friend of mine once told me, that when you want to know something about anything, put some fire under it. The fire brings out everything. You want to know something about a motherfucker? Put some fire under his ass. Well, when you put some fire under that cocaine, you know what it's made out of. ”
