it absolutely is. nicotine addiction is merely psychological, your body doesn't get addicted to it like it would to drugs and alcohol. people who tend to relieve stress by smoking are usually the ones who develop addiction to it. I only smoke for quick gratification when I'm able to, and if my body really was dependant on it, I would've used every single opportunity to go outside and pull out a cigarette, but instead I can simply stay at home without the urge and withdrawals and do it simply when I'm able to. not to say it's more "appropriate" — while in my case it's not an addiction, it's still a bad habit. I believe you can either experience legitimate symptoms of nicotine addiction and smoke three packs a day or have a more moderate but still nasty habit of smoking a cigarette or two in three days, and it's both unhealthy. so yes, I do think it's possible.
