explain What is smoking, effects of smoking and How can be prevented it

Answer 1

What is smoking?

Smoking is a hard habit to break because tobacco contains nicotine, which is highly addictive. Like heroin or other addictive drugs, the body and mind quickly become so used to the nicotine in cigarettes that a person needs to have it just to feel normal. 

effects of smoking :

Smoking changes the structure of blood vessels. This can lead to the buildup of plaque that hardens and narrows the vessels, causing a disease called atherosclerosis. Atherosclerosis is a common cause of heart attacks and peripheral artery disease. Smoking increases your likelihood of developing high blood pressure. The carbon monoxide inhaled from cigarette smoke interferes with the way oxygen is carried by your blood to organs, including the heart, which links it to heart disease. Smoking also increases the incidence of blood clots, which can lead to strokes.
