Many people believe that smoking is dangerous for health. Smoking means saving illnesses. They may not appear now, but they will surely appear someday. It has been said that cigarettes contain many dangerous contents. They contain thousands of chemical agents, for example carbon monoxide (CO), nicotine, tar, nitric oxide, methane, benzene, and other chemical agents. The amounts of these chemical agents are very little, but they can be accumulated in the body and they will cause adverse reactions to the cell of the tissues and body organs.
Cigarettes cause many illnesses. However, the most common illness caused by cigarettes is heart disease. This is because of the damage of the endothelia of vascular tissues. The damage will lead to the hardness of arteries, which has been known as arteriosclerosis. When arteriosclerosis develops, the affected arteries will loose their ability to relax and the size of their lumens will be reduced as well. This lead to hypertension, coronary heart disease, thrombophlebitis and even cerebrovascular accidents (stroke). The damage on the endothels is a perfect site for thrombus to develop. When the thrombus blocks the lumen of the artery totally, the blood flows to the distal tissue will stop and leads to the ischemic of the tissues. If this happens to cardiac tissues, this will cause ischemic heart disease and even death.
As for pregnant women, cigarettes cause fetal growth restriction, under wight baby born and pre-term delivering. Unfortunately, many smoking women do not realize this. They keep smoking even if they are pregnant. Cigarettes cause many serious illnesses is indisputable but why the government seems to do nothing. Victims have increased year by year, anti smoking is only promoted by non government organizations. The government itself seems to neglect the people's health. Some of us should be agree with the motto saying that put out your cigarette now or it will put you out.
