As I'm reading this, I find myself wondering... wherever are you getting this information? Then, of course, I get down to the sources: theantidrug.com, shesinrecovery.com, well.com, and healthy.net. All of these websites are pushing their agenda and aren't what I would call reliable.

washington.edu and nih.gov are much better sources, but they don't actually use the word, "damage," in reference to changes induced by cocaine exposure. In fact, they don't say cocaine does anything to the brain except affect the dopamine neurotransmitter system! Yes, it increases the risk of various health related issues, but that's not equivalent to brain damage.

mit.edu is talking about prenatal exposure and doesn't apply to your paper. Why did you use this again?

Do your research and stop being hysterical. Cocaine is addictive, yes. Cocaine can change the way your brain functions, yes. Cocaine can even increase your risk of siezures, heart attack and stroke, but cocaine is not the devil nor the worst thing on the market. It's reports like these that get the public's opinion's skewed and changes the way society deals with these problems. We need the facts so that we can deal with them appropriately.
