Nah, what's all this harm reduction stuff, telling people about better sources of water? Filthy cup of hairy, ashy, bloody standing water is the way forward. Ask the big expert over there. Of course, I'd be worried about the risk for catching hep/HIV if I was using that for injection water, but presumably BHM has no mates around, ever, so it's not a problem. It should also be obvious that for IM injection, bacterial and viral contamination is a very serious concern, much more than it is for IVing, and that a manky old cup is a great way to develop an abcess, but I think that nuance and common sense have, as per fucking usual, eluded our shortsighted simian assistant.
