Question

2. What effects do tar and carbon monoxide have on the bodies of smokers?​

Answer 1

Tar is present in any tobacco product that is burned.
The last puffs on a cigarette can contain as much as twice the amount of tar as the first puffs. Tar in cigarette smoke paralyzes the cilia in the lungs and contributes to lung diseases such as emphysema, chronic bronchitis, and lung cancer.
