Sort of OT in that the topic has diverged somewhat, but the particular cheap nasty low grade short duration product mentioned in the OP has always struck me as begging for a supernatural horror treatment. Or a slightly-horror-toned superhero treatment!

If there was anything that ever came out of the Pentex labs, it would be Krokodil as-is in real life... only you'd also get a free bane spirit possession along with your flesh destruction and gangrene.

In a superhero game, take the description of Krokodil's effects on the body, neglect to mention the "because of gangrene" part, and Krokodil turns into a mutagen that grants High Pain Threshold, hysterical strength (from not being able to feel the damage), and accumulating DR (Tough Skin), Numb and Appearance loss. Throw in your super-villain (who is probably giving the pure stuff to his thugs to get super-minions, and they're selling cut doses on the street for extra cash) and you have a whole adventure.

I may actually have posted links to articles on Krokodil into the real life weirdness thread at some point.
