you may still be at risk but it will be a much less break that you will .. stop smoking now and you will join years to your life
you might be because your lungs are in a minute still covered with asphalt from the chemicals in the cigarettes. if you didn't start, you would be in good health. sorry to say adjectives these mean things to you. i didn't suggest any harm near what i said.
