When I did a line of coke it was good but now my lungs hurt from the inside why?

your lungs hurt from doing the coke. stupid choice. coke destroys your body from the inside out. if you must do drugs i'd rather see you smoking marijuana. that's the only drug that doesn't bother me. but i still wish you won't do coke again or any drugs. the only benefit you get is how the drug makes you feel.
