What are the dangers of smoking for teenagers

Nowadays, many teenagers have started smoking. In fact, this is a very bad behavior. Some teenagers think smoking is very impressive, while others do so because they are addicted. So do you understand the harm of smoking to teenagers? I believe that after reading this content, you will understand how big the impact is.

Smoking can cause a variety of brain diseases, reduce the oxygen and blood circulation in the brain, cause bleeding and blockage of brain blood vessels, and lead to paralysis, mental decline and stroke. Smoking can cause throat cancer. Most laryngeal cancer patients are male. Otolaryngologists have found that most smokers have hoarse throats. This may be related to the tar in the smoke.

Studies have found that smoking increases the stickiness of platelets in the blood, which makes the blood easier to coagulate and thus easily forms blood clots in the coronary arteries. At the same time, smoking also increases the low-density cholesterol in the blood, which makes it easy for fatty substances to deposit in blood vessels and form coronary atherosclerosis. If the coronary artery becomes hardened, its inner lumen will become narrower. Once the blood coagulates inside, the artery will be blocked. At this time, oxygen cannot be delivered to that part of the heart muscle, and the myocardial cells will fail and die due to lack of oxygen. This is myocardial infarction. Local myocardial infarction can cause angina pectoris, while large-scale myocardial infarction can cause shock or death due to sudden cessation of heart beating. This is acute myocardial infarction.

Doctors' advice to smokers is: If you have high blood pressure, high blood lipids, heart disease or a family history of heart disease, you should stop smoking immediately, because smoking will increase your risk of myocardial infarction by dozens of times. Smoking causes 25% of all heart disease deaths. The prevalence rate is twice as high among smokers over 50 years old. The prevalence rate among smokers under 50 years old is 9 to 14 times higher.

So smoking is basically of no benefit to our body, especially for teenagers. Your body is still in a developmental stage. If you ruin your body because of these things, will you regret it very much? If so, I advise you to quit smoking as soon as possible.
