In addition to all of the immediate and long-term symptoms resulting from using cocaine, crack users can also experience bleeding in the lungs from the bursting of small blood vessels.
Crack can cause a chronic cough that can contains phlegm with blood, and chest pain, making it difficult to breathe. Both regular cocaine and crack use can produce a fluid in the lungs called pulmonary edema, as a result from damage to the small vessels lining the air sacs. No antidote exists for cocaine overdose, nor are there maintenance programs as for treating heroin addiction. And unlike chronic heroin users who usually develop their addiction quickly, cocaine addiction can evolve over long periods of time, more similar to alcohol.
