my mother used to drink coffee by the pot and sometimes have two cigarettes going at the same time. however, when my brother in law and armchair psychologist said "she has an addictive personality," I wanted to fly out of my bones and put a rag over his face. I guess he conveniently forgot that she hadn't drank alcohol in decades. the drug dealers (pharmaceutical industry) glommed on to the term addictive personality when they began heavily pushing oxy.
