Yivin, I doubt that smoking is your habit, I'm guessing it is your addiction. There is a difference. While I'm against smoking because of many reasons, the thing I'm most against is the tobacco companies being able to regulate the amount of nicotine in their tobacco products. If they made nicotine free cigarettes (they can and have done it) and you smoked those, and only those it would be a habit. But since they don't sell nicotine free cigarettes what you have is a good old fashioned addiction.
