Thats like saying cutting yourself with a razor blade is good for you cause it's killing cells so they grow back faster, but with that there is an increased chance of infectionnot to menturn all the nasty chemicals and toxins that would get into your body and the scar it would leave, smoking is a lot like cutting your lungs with a razor blade, it's not gonna kill you (right away) but it's cirtanly not good for you.

And no matter how little you smoke it's stil, bad for you, just the less you smoke the less bad it is for you and the less chance you have of gettig cancer.

I'm not saying if you smoke you will die, but it does increase your chances of dieing (later in life mind you), it's a risk every smoker (yes even me) has to live with.
