smoking has many serious effects. The most obvious effect is the deterioration of a smoker's health. Smoking increases the risk of lung disease,increase blood pressure,increase the risk of heart attacks,and reduces the flow of oxygen to the brain.
Smoking creates respiratory or breath problems. A smoker's cough expels phlegm (thick mucus in the nose and the throat that wants to escape the body). Prolonged use may lead to emphysema and the need to hook up to a machine to pump enough oxygen into the lungs. Another effect of this habit is that smoking breeds or produces halitosis;a smoker's breath smells foul and repulsive. smoking frequently result in social isolation because fewer people smoke or want to be in the presence of second-hand smoke.
