You are a nicotine addict. Plain and simple you are a drug addict and your drug of choice is nicotine. You don't smoke cigarettes because you like the way they taste, you like the way cigarettes taste because you are addicted to nicotine.
You don't inhale hot, acrid, particulate carcinogens because you have a death wish, you smoke despite the warnings because it is a very efficient nicotine delivery method - You are very impatient when it comes to getting your fix.
You don't wake up each morning unable to function until you have had a few cigarettes and coffee because you need nicotine and caffeine to survive, you are slowly diminishing your ability to survive with the tortuous cycle of nicotine and caffeine highs and lows that you put your body through - The more you smoke, the more you need to smoke (That is known as developing a tolerance, one of the tests for whether a substance is addictive.)
If you are a visitor here or are in the first few days of withdrawl from nicotine waiting to apply for membership, know this: It gets much better and it gets much easier.
Life without nicotine is not a sacrifice, it is freedom from the death sentence you are serving voluntarily. Life without cigarettes is not difficult, it is an infinitely easier and healthier existence. While in the first few days of withdrawl, the relief you are seeking from the cravings lies not in smoking a cigarette to reinforce your addiction, but in denying yourself that short term relief in favor of a life free of the bondage of hourly feeding cycles through a delivery device that has a 50 / 50 chance of ending your life early and if it does not, will over time, significantly diminish the quality of the life you live.
You smoke by choice. Decide that you can live without nicotine and you can. Decide that you are hopelessly addicted and you are. Never believe for a second that you are smoking due to circumstance, stress or habit. You smoke because you are a nicotine addict. Choose to never take another puff and you choose freedom. Choose freedom and you choose life.
