Answer:
Drug abuse may lead to all of the above.
Explanation:
While all of the above ingredients are in a cigarette, nicotine is the stimulant that causes addiction and dependency.
It can damage nearly every organ in the body, including the lungs, heart, blood vessels, reproductive organs, mouth, skin, eyes, and bones.
Smoking damages the airways and small air sacs in your lungs. This damage starts early in smokers, and lung function continues to worsen as long as the person smokes. Still, it may take years for the problem to become noticeable enough for lung disease to be diagnosed.
Smoking makes pneumonia and asthma worse. It also causes many other lung diseases that can be nearly as bad as lung cancer.
