<s>[INST] i swallowed crystal meth (not the tablets) then a few hours later i coughed up dark green phlem, my right side of my chest feels swollen and the same with my neck. coughing up green stopped but the swelling feeling is still there, no outer swelling though... it hurts and i can only take 75% of a breath.... what does this mean? [/INST] It is possible that some of the drug might have gone into lungs and or if you were drinking or eating that might have gone in to lungs.You need to get atleast a chest xray to find out the condition of your lungs.And then treat.Also take deep breaths to clear lungs. </s>
