Addiction.

A conversation with a colleague while we were on a cigarette break:

Me: That methadone place fucked this one up. People who put together detox programs are morons.

Him: People who get hooked on drugs are morons.

Me: It's addiction, man.

An email from a friend of mine upon learning of the above conversation:

"He was smoking a cigarette and calling addicts names."

(Note: I really wish I'd come up with that response on my own. Instead of "It's addiction, man," I wish I'd said instead, "Aptly stated by a man smoking a cigarette." Yet again, I am humbled by a friend who is far more brilliant than I.)
