For about a month or 2 I have been smoking Marijuana poppers, where you take a rip from a cigarette and you put it in a shaft and stamp the shaft down with Marijuana. I went to a party where I smoked 4-5 of these poppers and when I got home I started having difficulty breathing. I went to the walk-in clinic and he said it was just a burn on the inside of my throat and he gave me some medicine to subside the effects. The trouble breathing continued but it wasn't as bad and I only got it when I was tired or at rest. yesterday I started coughing up little pieces of blood in my saliva and today I coughed up some yellow mucous with a decent sized chunk of blood in it. What do I do now?
