Well, I imagine most people do krokodil because they are addicted to opiates. You get hooked on a different opiate, and when the only thing you can come across is an opiate that eats your flesh, you take it to feed your addiction anyway. Addiction is a powerful thing. The user reaches a point where their drug use isn't about getting high. It's about making the sickness you feel from withdrawl going away. It's a powerful sickness that your brain knows can disappear if you only feed the addiction. The fact that the drug eats your flesh becomes an afterthought when all you can think of is making the sickness go away.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
