What is the initial drive for anyone to light one up? I feel like want to smoke a cigarette in every few hours. Am I addicted to nicotine or is it just a force of habit? When I run out of cigs, I will move mountains to get another packet. I feel I need them so badly and then when I have some and smoked one, I don't really care about them. It's weird. What are your thoughts on whether smoking is a habit or an addiction?
