उत्तर
Tobacco use is deadly because nicotine is highly addictive and raises blood pressure. Cigarette smoke contains about 4000 chemicals, many of which cause cancer. It also releases poisonous carbon monoxide and tar, which damage the lungs. Smokeless tobacco products like gutkha, khaini and pan masala cause oral cancer, and their use during pregnancy harms even unborn babies.
