Nate, I say I wasn't addicted to cigarettes because of this:
"impaired control over drug use, compulsive use, continued use despite harm, and craving."
This was in the late seventies and early eighties, working graveyard shift as a hash-slinger at a Denny's restaurant. Everyone on the staff smoked. It was acceptable, it was encouraged, it was sociable and helped pass the time during quiet periods. I never had "impaired control, compulsive use or continued use despite harm, and craving." I chose to smoke. When I left the job, I chose to stop smoking as I was moving in different circles and it was no longer acceptable behavior.
BTW, the definition I use is from the American Society of Addiction Medicine consensus document, urging the DSM committee to clarify the terminology.
"We agree that the DSM Committees’ choice of terminology to date is problematic. The use of the term "dependence" as a euphemism for addiction originated as a well-intentioned attempt to counter negative effects of the social stigmatization of addicted patients. Unfortunately, it has resulted in creating significant confusion in discussions of management by clouding the important distinction between physical dependence and uncontrolled psychological craving (addiction). Examples of this confusion are replete in the literature."
