Krokodil (aka desomorphine or 4,5-α-Epoxy-17-methylmorphinan-3-ol to nerds) is the coolest fucking shit since bath salts. A relatively cheap yet staggeringly potent drug it comes all the way from Mother Russia (Siberia, to be precise) so you know it's good; if you're from a country within which people routinely drink vodka for breakfast you need something with a little more pep than cocaine to get you high.
This thing is only for non-pussies. If you're a little bitch you should keep far, far away and go back to smoking weed and sucking on your mom's dried-up titties like the little baby you are.
