Cause 90% of lung cancers

Tobacco is considered one of the most harmful pastimes in the world. They are just as addictive as drugs. However, not all men know this.

The poison is hard to quit Dr. Kazushige Noda, Department of General Internal Medicine, Vinmec International General Hospital said that many serious diseases are caused by tobacco. Among them, cancer is the most well-known disease among them because of its dangerous level. “90% of lung cancers today are caused by smoking with the characteristic symptoms of coughing up blood or shortness of breath. However, this dangerous disease sometimes manifests itself simply as fatigue or loss of appetite, even without symptoms until the disease has advanced. Smoking also causes cancer in many other parts of the body such as mouth, esophagus, bladder, etc., "said Dr. Noda. Chronic obstructive pulmonary disease - one of the most disabling and fatal diseases in the world today is also a common disease in people with a history of smoking. In addition, smoking also clogs and narrows the arteries, causing stroke and coronary heart disease. According to Dr. Noda, although the harmful effects of smoking are proven in practice, it is very difficult to quit smoking. The reason is because in cigarettes contains nicotine, a very addictive substance. Nicotine affects the brain quickly and can cause a temporary feeling of relaxation and stress relief. In particular, according to studies, nicotine makes smokers 10 times more high than addiction to drugs such as heroin, cocaine or amphetamine. They stimulate the production of dopamine, neurotoxicity and addiction. If you stop smoking, the concentration of nicotine in the blood decreases, leading to a decrease in dopamine, causing mental confusion, fatigue, irritability, and feeling incapacitated. “Particularly with pipe tobacco, besides containing hundreds of carcinogens similar to cigarettes, they also contain nine times more nicotine. That means pipe tobacco is more addictive than regular cigarettes,” added Dr. Noda. According to this expert, smoking is not only dangerous to the direct users but also has a great impact on the people around. Accordingly, secondhand smoke can cause illness and premature death in children and adults who smoke. In the long term, passive smokers have an increased risk of lung cancer, heart disease, stroke, and other respiratory problems. Secondhand smoke exposure during pregnancy increases the risk of problems such as miscarriage, stillbirth, and ectopic pregnancy. Infants and children who are regularly exposed to secondhand smoke are more prone to sudden infant death syndrome (SIDS), asthma and chronic cough, learning disabilities, and behavioral problems. “The fact that a man smokes is clearly harmful to babies, children and women's health. That means, this is a dangerous agent for human reproductive capacity," he emphasized.
