I think its self explanatory, on what type of smoker you are. You don't need a reason to smoke. Lighting a cigarette is as normal to you as breathing. Its a necessity, rather than a choice. Your body craves the nicotine, and you give it to your body with no question. There is no hesitance to light a full cigarette even if you are a few steps away from a non-smoking area, as long as you get a few puffs before throwing it away.
