How much tar is in my lungs when i smoke 1 cigarette an hour?

A doctor has provided 1 answer

SMOKING: Your lungs are soft or spongy but with much smoking, it becomes hard like board and you will have problem breathing. You call that copd. Soon you will be carrying oxygen tank in order to breath. That's how you will become if you smoke half a pack a day.
