Nope..because I have several- sparing a few others from having any.  It really is genetic....Now lets see..while I go out to have a smoke could you please find me a chocolate bar, some coffee, bring all of my animals to me, and please don't close down aka!!!!!!

Genetic predisposition plays into it, also your past/childhood trauma, current happiness in life as well as many other things. If it was as easy as walking away, the world would not have as many addicts as we do.
It doesnt matter what the addiction is..it's all the same.And its hard to overcome.

We pretty much all have some sort of addiction. It's human nature and goes  against the odds not to have one or two..........
