" My best guess about my own attraction to the habit is that I belong to a class of people whose lives are insufficiently structured...
We embrace a toxin as deadly as nicotine...because we have not yet found pleasures or routines that can replace the comforting, structure bringing rhythm of need and gratification that the cigarette habit offers. One word for this structuring might be "self medication"; another might be "coping". "
― Jonathan Franzen , How to Be Alone
