A cheap heroin knockoff that can be synthesized with codeine based OTC pain medicine and cheap, widely available chemicals. The price of krokodil is approximately 10% of street heroin. It is a very popular drug in Russia, where heroin use is the highest in the world, primarily due to Russia's close proximity to Afghanistan.
The drug is extremely dangerous, causing sores and other dermatological issues. The drug breaks down skin and muscle fibers at an astounding rate. The life expectancy of a heavy user is approximately 2-3 years from when the habit begins.

Chris: What are those sores all over the back of your neck?
