This is all ridiculous. Shoot the AH full of any of the zillions of drugs that make you die in a minute or two and be done with it, fer cripesake. Or just pop a couple of caps to the head, where most of these guys come from that is in no way “unusual”.
as far as I can tell - heroin is quite deadly.
I don’t understand why it seems so difficult to come up with the right concoction.
