Studies have found that women who regularly smoke passively in the workplace have a higher incidence of coronary heart disease than those who do not or rarely smoke passively in the workplace. According to an international sample survey, 50% of the patients with cancer caused by smoking are passive smokers. A large number of epidemiological surveys have shown that the prevalence of lung cancer in wives of husbands who smoke is 1.6 to 3.4 times higher than that of non-smokers. Passive smoking in pregnant women can affect the normal growth and development of the fetus. Some scholars have analyzed more than 5000 pregnant women and found that when the husband smokes more than 10 cigarettes a day, the prenatal mortality rate of his fetus increases by 65%, and the more he smokes, the higher the mortality rate. More children in smoking families suffer from respiratory diseases than in non-smoking families. Therefore, it is important to note that the dangers and consequences of passive smoking are also very serious and must be given great attention. It is clinically proven that passive smoking can also induce chronic bronchitis, chronic wheezing bronchitis, emphysema, and pulmonary heart disease. The vast majority of children, adolescents and middle-aged and elderly women who have no history of smoking have a chronic cough and asthma that is caused by smoking by family members or colleagues. Smoking is harmful to human health, and for the sake of longevity, family happiness, and optimal reproduction of future generations, wise people can easily quit the habit of smoking, a conditioned reflex (addiction) formed by the transient narcotic effect of cigarettes, with rational perseverance, and for those who do not know enough about the dangers of smoking, they can use Drugs to assist in quitting.
