So i've had this pipe that I bought that I thought was completely safe to smoke from, Then I read about metal poisoning and shit and started getting a little anxious. This is how the pipe looks like ; http://i.imgur.com/B6D591m.jpg Its made from metal, Not sure exactly which kind and that stuff. Another bad thing i've done is clean it with water alot of times, It smells really bad and looks like shit. I took a straw and put it inside the hole to try and clean it and it comes out with like a sort of sticky orange looking substance, I dont know its kinda weird coloring, Sorta dark orange or somthing like that and its really sticky. I binge smoked with this pipe in this condiation for like a whole 15gram, It tasted really bad aswell. I obviously would never smoke from it anymore but im wondering how dangerous is this really? and could I have gotten some kind of metal poisoning from that binge ?
