If that is the medical definition of addiction, since nicotine use, absent smoking, has not been shown to result in disablility or premature death or significant problems with one’s behaviors and interpersonal relationships (nor does it cause most people "severe" trauma to quit,) I'm not sure nicotine use is really a true addiction then.
I belive most people could avoid nicotine use - they simply choose not to. Nicotine "addiction" cannot even begin to be compared with other addictions regarding the negative impact on one's life. It seems cliche to say, but you don't see nicotine "addicts" knocking over drug stores or prostituting themselves for a fix!
Before the age of narcotics, addiction had a different definition. It simply meant something that a person couldn't live without.
Postive addiction has been recognized by psychologists as a good thing and something that can be used to avoid bad addictions. Another example would be people who have a daily workout routine. They widely report that missing their workout has negative effects on their mood and behavior - classic withdrawl symptoms. It literally helps them function - even increasing their cognative abilities. These aren't obsessive workout addicts that over exercise because they have poor body image - just average, healthy 20 minute workouts. Their workouts bring them only positive results, yet since cessation brings extreme discomfort, they truly are addicted in every sense. So how is that undesirable? I would LOVE to be addicted to a 20 minute daily workout! LOL!
So, if there can be positive and negative addictions, there can be varying degrees in between, as well. (I can't control my heart beating either, but that doesn't mean I consider it undesirable! lol)
to be fair- the only reason that people are prostituting them selves and stealing for their next fix of illegal drugs is because the black market drives the prices up and make it unaffordable and impossible to sustain their habits on a normal income. smoking has been prove in many studies to be just as addictive as ....... it being legal is a major reason that you don't see people with nicotine addictions having such severe consequences.
