In medicine, the scientific name of tobacco addiction is nicotine addiction disorder or nicotine dependence disorder, which refers to the symptoms of addiction to nicotine, the main substance contained in tobacco, by long-term smokers, so quitting smoking is also called quitting nicotine dependence disorder or quitting nicotine addiction disorder. In medicine, tobacco addiction (nicotine addiction disorder) is treated as a chronic disease. Smokers are treated as patients, so quitting smoking is a medical practice, and the increasing number of smoking cessation clinics is a better proof of this. The nicotine in tobacco is a neurotoxin that mainly affects the nervous system. Some smokers subjectively feel that smoking can relieve fatigue, invigorate the spirit, etc. This is a transient excitement of the nervous system, in fact, the euphoria caused by nicotine. After the excitement, the nervous system is then inhibited. Therefore, the sensitivity and accuracy of neuromuscular responses are reduced after smoking. The results of a study conducted by a foreign psychological research institute showed that the intellectual performance of smokers was 10.6% lower than that of nonsmokers. In November 1987, the World Health Organization (WHO) in At the 6th International Conference on Smoking and Health in Tokyo, Japan, it was recommended that April 7, 1988, the 40th anniversary of the World Health Organization In November 1987, at the 6th International Conference on Smoking and Health in Tokyo, Japan, the WHO recommended that April 7, 1988, the 40th anniversary of the WHO, be designated as World No Tobacco Day, with the slogan “Smoke or Be Healthy. In 1989, the World Health Organization rescheduled this day to May 31 each year. This year, May 31, we will welcome the 22nd World No Tobacco Day, but the current situation of smoking in China is not optimistic: the number of smokers is increasing, reaching 320 million people, the average age of smokers is decreasing, female smokers and The number of young people smoking is increasing. China’s tobacco production and consumption also ranks eight “world first”: the world’s first baked tobacco planting area; baked tobacco production in the world: the world’s first growth rate of baked tobacco; cigarette production and sales in the world; the world’s first growth rate of cigarettes; the number of smokers in the world; the number of smokers increased by the world’s first; tobacco tax growth rate in the world. The China World Records Association has included these eight world firsts. Tax revenue from the tobacco industry accounts for 10 percent of the country’s total tax revenue. From the classification of economics, although the government gets tax revenue from tobacco, but tobacco revenue can never make up for the loss of disease, premature death, sick pay, medical expenses, etc. caused by tobacco damage. Smoking is bad for your health, everyone will say, but do you know, the probability of smoking life-threatening to what extent? The dangers of smoking According to a British media report on October 6, scientists have warned that tens of millions of people will die from respiratory and lung cancer in China over the next 25 years if no measures are taken to reduce smoking and indoor burning. From 2003 to 2033, 65 million people will die of chronic obstructive pulmonary disease (COPD) in China, while smoking and indoor combustion will cause 18 million deaths. In response, researchers at the Harvard School of Public Health say these two figures account for 19 percent and 5 percent, respectively, of all deaths in China over the same period. Smoking and pollution from burning materials are the main contributing factors, according to the researchers. Majid Ezzati, an associate professor of international health at the Harvard School of Public Health, said that China has a high rate of smoking and pollution. Ezzati analyzed that more than half of China’s men smoke, and that the burning of leaves and other garbage in cities, straw burning in rural areas and indoor burning also contribute to the high incidence of respiratory diseases such as tuberculosis, chronic obstructive pulmonary disease and even lung cancer. In addition, both rural and urban households are rarely equipped with ventilation and ventilators, resulting in high indoor concentrations of respirable particles, carbon dioxide and sulfur dioxide. This may also be associated with a high incidence of lung disease. Therefore, Ezzati suggests that China should adopt proven methods to reduce the number of smokers and provide clean energy in homes. If these measures are actually implemented, 26 million fewer people could die from COPD and 6.3 million fewer people could die from lung cancer by 2033. Controlling the number of smokers is also an urgent priority. Not only China, but also other countries are making unremitting efforts to do so. Recently, the British government, in order to encourage 10 million smokers to quit smoking, plans to require all tobacco product boxes from November onwards, such as corrosive teeth and throat tumors printed on the picture. The country’s health department pointed out that, in addition, also intends to be healthy lungs and tar-corroded lungs comparison pictures printed on the front of the cigarette box.
