What harm does smoking do to family members?

Smoking in the brain can cause a variety of brain diseases, reduce oxygen and blood circulating in the brain, lead to cerebral vascular bleeding and occlusion, and lead to paralysis, mental decline and stroke. The cause of stroke is that smoking leads to cerebral vasospasm, which makes blood coagulation easier. Smokers are twice as likely to have a stroke as nonsmokers.

Laryngeal smoking can cause laryngeal cancer. Laryngeal cancer patients are mostly male.

Smoking can cause fat accumulation and vascular occlusion on the heart and blood vessels, making smokers prone to coronary heart disease. The death rate of heart disease caused by smoking accounts for 25% of the total. The prevalence of smokers over 50 has doubled. The prevalence rate of smokers under 50 years old increased 9 times, reaching 14 times. Smoking will constrict blood vessels, slow down the circulation of blood and oxygen, and eventually lead to thickening of blood vessel walls, leading to coronary heart disease and stroke. Smoking will completely block the blood circulation of hands and feet, leading to amputation.

Smoking in the lungs can cause lung cancer. 90% of the total mortality rate is caused by smoking. People smoke ten cigarettes a day, and the prevalence rate is ten times that of non-smokers. The damaged cells are abnormal. The initial symptoms will not be found until the cancer cells spread to blood vessels and other organs. Smoking can also cause emphysema, and toxic substances accumulated in the bronchi of the lungs will hinder the normal exhalation of the air inhaled by the human body, make lung cells expand or rupture, and cause patients to have difficulty breathing.

For people with gastrointestinal diseases, smoking is enough to make them worse. People with gastric ulcer or duodenal ulcer will slow down the healing of ulcer and even become chronic diseases. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, make the gastrointestinal tract often tense, and lead to the loss of appetite of smokers. In addition, nicotine can also contract gastrointestinal mucosal blood vessels and reduce appetite.

Bone smokers have a longer fracture recovery period than non-smokers. It may be that nicotine and carbon monoxide contained in cigarettes slow down the process of bone regeneration. Nicotine constricts blood vessels and reduces blood flow to new bones. The carbon monoxide inhaled during smoking also reduces the speed at which oxygen enters the body. Smoking can lead to osteitis and back pain. Smoking more than ten cigarettes a day will double the prevalence of periostitis.
