Oh wow. Don't apologize to me, pal -- you're the one denying cocaine's neurotoxicity. I'm an occasional cocaine user, but at least I don't pretend like it's healthy. Let's list some sources...
"Finally, a loss of vesicular monoamine transporters, neurofilament proteins, and other morphological changes appear to indicate a long term damage of dopamine neurons."
"Years after the abuse has ended, many ex-abusers report a noticeably reduced attention span."
"In addition to the intense damage cocaine can cause to the liver, intestines, heart, and lungs, even casual use of the drug will impair the brain and cause serious damage to the central nervous system."
"Little hypothesizes that the decreased dopamine vesicles and increased transporters may contribute to cocaine-induced depression and other depressive disorders."
