Can doing meth for the first time set up a disease in your lungs? I did it for the first time a week ago. I did it once for four days, and then I realized what was happening. And I started coughing on the second day and it keeps getting worse even now that I've stopped. It burns in my chest and I'm hacking up clear stuff. I still haven't slept or ate even though I've been off of it for two days. Did I have a bad reaction? What's going on with my lungs?
