Smoking "escort" is harmful to health. Smoking is harmful to health, which is common knowledge known to all men, women and children.

Can you lose weight by smoking?

Smoking is not equal to losing weight.

Second, how much nicotine is inhaled will kill people.

Nicotine is an odorous, bitter, colorless and transparent oily liquid, which is highly volatile and easily oxidized to dark gray in the air. It can be quickly dissolved in water and alcohol and easily absorbed by human body through oral cavity, nasal cavity and bronchial mucosa. Nicotine stuck to the skin surface will "penetrate" into the human body.

The lethal dose of nicotine in cigarettes is 50-70 mg, which is equivalent to the nicotine content of 20-25 cigarettes. If nicotine in a cigar or three cigarettes is injected into a person's vein at one time, the person will die within 3-5 minutes.

During the Ming Dynasty in China, someone died of acute poisoning due to excessive smoking, so Emperor Chongzhen ordered a ban on smoking. Such a case has also been reported abroad: a young man in the former Soviet Union smoked for the first time and died after smoking a big cigar; A 40-year-old healthy man who has been smoking for a long time in Britain smoked 14 cigars and 40 cigarettes overnight because he was engaged in an important job. I felt sick in the morning and died after being rescued. A French club once held a smoking competition. After smoking 60 cigarettes, the winner died before receiving the prize. Other contestants were taken to the hospital for emergency treatment.

There are many people who smoke more than one box (20 cigarettes) a day, and the nicotine content greatly exceeds the lethal dose of people. Why are there so few people suffering from acute poisoning? The reason is that some nicotine in tobacco diffuses into the air with smoke, and most smokers do not smoke continuously, so nicotine enters the human body intermittently and slowly. But long-term smoking can make people "chronically poisoned" and cause many serious diseases.

Third, smoking is prone to 14 kinds of cancer.

"Smoking is harmful to health", which is a warning on the cigarette case. This shows that smoking is very dangerous to people's health. So the World Health Organization predicts that if people don't smoke, the number of cancers in the world will be reduced by one third in five years.

As early as 1934, the famous German journal Frankfurter Pathology published a medical paper by Mr. Lu, a foreign student from China, which revealed the carcinogenicity of tobacco, so Lu became the first person in the world to reveal the secret that tobacco contains carcinogens. Now, according to years of research by experts, cigarettes contain more than 4,000 different chemicals, of which at least 43 are carcinogens. Therefore, experts warn that smoking is associated with at least 14 different cancers. For example, smoking is the main cause of lung cancer. Scientists who study cancer have proved that women infected with sexually transmitted papillomavirus are more likely to develop uterine cancer if inhaled.

American researchers believe that carcinogens in tobacco have different effects on men and women. In the study of lung cancer, it is found that women are more susceptible to the carcinogenesis of tobacco, and smoking women are more susceptible to bladder cancer than smoking men. Researchers from Leiden University in the Netherlands recently investigated the smoking status of 740 patients with skin cancer, including 16 1 patients with squamous cell carcinoma, and compared them with 386 subjects without skin cancer.

The results showed that the risk of smokers suffering from squamous cell carcinoma was 1.9 times that of non-smokers. The more smokers, the greater the risk, which proved that smokers were prone to skin cancer.

Studies have also shown that smoking is related to at least eight other serious diseases, including heart disease, stroke, emphysema, cataract and blood circulation diseases. Moreover, smoking will also affect sexual health and fertility and reduce the birth weight of babies. A new study in the United States shows that about 44% of smokers suffer from mental illness.

Over the years, although the China government has strengthened the efforts to ban smoking in public places, restricted the advertising and promotion activities of tobacco products, and the harm of tobacco has been discovered and recognized by more and more people, many smokers still hold a fluke mentality, but they don't know that smoking is not only equivalent to chronic suicide, but also poisons their relatives and friends. It can be said that once people start smoking, it is equivalent to inviting cancer into life.

Smoking is an act that harms others, so please don't smoke for the health of you and others!
