I find ECF (and forums in general) more addictive than vaping (nicotine). Perhaps I'm alone in that, but I don't think so. And it's not like I need to post to feed that addiction. I'm guessing lurkers can relate to what I'm saying.
Regarding DSM-5 and criteria for substance disorder, I found this (on pretty basic google search):
- Taking the substance in larger amounts or for longer than the you meant to
- Wanting to cut down or stop using the substance but not managing to
- Spending a lot of time getting, using, or recovering from use of the substance
- Cravings and urges to use the substance
- Not managing to do what you should at work, home or school, because of substance use
- Continuing to use, even when it causes problems in relationships
- Giving up important social, occupational or recreational activities because of substance use
- Using substances again and again, even when it puts the you in danger
- Continuing to use, even when the you know you have a physical or psychological problem that could have been caused or made worse by the substance
- Needing more of the substance to get the effect you want (tolerance)
- Development of withdrawal symptoms, which can be relieved by taking more of the substance.
And I'm pretty sure addiction or dependence, for an individual, depends on how many of the 11 criteria a person is subjected to. For professionals (licensed therapists) that might care to apply the term to an individual, it would be a matter of not just assessment, but treatment. Ideally, overcoming the disorder, or at very least, finding healthy ways to cope and manage it.
At any rate, it would seem if "addiction to smoking cigarettes" were an individual's problem, then vaping could be, I would think, an effective / healthy way to manage the presumed disorder from smoking. But if vaping (nicotine) is seen as simply substituting dependence for one form, I would think vapers have (as a group) been able to demonstrate ability to resolve #2, by being able to cut down or even stop use of nicotine. And when comparing vaping to smoking (nicotine), #4 is certainly reported as substantially less among vapers (who are also ex-smokers). #5 seems overcome with vaping, unless usage ban is in place, but even then, because of #4 is far less of an issue.
Most on the criteria list seem either non-existent when it comes to vaping nicotine, or very tame. But admittedly, at least in my case, I would say #1, #3, #10, #11, and maybe (slight maybe) on #9 are possible items that come from vaping nicotine.
I'll also note, again, that I was able to go cold turkey 3 times from smoking, once for 8+ years, and never less than a year. I currently call myself a moderate smoker, but am about half way thru a pack that I purchased sometime late in 2013, and truly have no cravings for a smoke.
