Out of curiosity, is there any distinction being drawn between "hard" and "soft" drugs? For example, is anyone being killed for selling/using marijuana, or is it all about heroin and meth?

Edit: I don't understand why someone would down vote this question. Taken at face value, the mandate to kill "drug users" could mean it's OK to shoot up a coffee shop or kill your neighbor for being an alcoholic, depending on where your particular culture draws the line.
