Should men smoke?

Some people think that smoking can excite nerves, help to think about problems and improve work efficiency; Others said, "A cigarette after a meal is better than a living fairy." Is that really the case? Some people tried the opposite answer. There are more than 20 kinds of toxins in the smoke emitted by tobacco after burning, and nicotine is the most harmful to life. In this regard, smoking has three main disadvantages:

1) can directly poison life. Some people have come to some amazing results through animal experiments, such as: no matter how big a horse can't stand injecting eight drops of nicotine, it will soon die; A lively dog can be killed without injecting a drop of nicotine into the vein; In addition, after smoking for a long time, some animals can find that there is an obvious trend of vasoconstriction and even hardening.

2) It can destroy the nutrients of human body. Smoking will prevent the body from absorbing vitamin C, and nicotine may get scurvy.

3) It can induce various diseases. Because the smoke inhaled into the human body has a malignant stimulating effect on respiratory tract, digestive tract and other organs, some people think that it is an inducing factor for gastric and duodenal ulcers, respiratory tract infections, and even cancers such as mouth, lips, tongue, esophagus, respiratory tract and lung.

From this point of view, smoking is harmful to human health. So try to quit or smoke less, and non-smokers should not get into this hobby.
