Four or so years ago, I had triple bypass surgury, and I threw away my last cigarettes in the hospital room...a real hardcore 30+ year smoker.
And I didn't smoke again for over three years, even though I worked in the cable tv biz, surrounded by heavy smokers.
Of course, after a split from my 7 year gf and the loss of my daughter, I was a little depressed...so I decided to allow myself the pleasure of one thing I could do anytime (pretty much), smoke cigarettes.
I am not an addictive personality, I guess, but I won't touch coke 'cause I grow over-fond rather quickly...my point is, get real!
Cigarettes are NOT anywhere near as addicting as just about any serious drug; what the problem is, is the internal weakness of the individual.
Most people won't deny themselves what they want if they can have it...personal control is severely lacking in most addicts.
Physical addiction is a fact, but severe psychosis and agonizing body pain don't equate with nervousness and mild panic attacks, as is the case with nic withdrawal.
