On World No Tobacco Day, let's say "no" to tobacco.

I believe everyone has heard the saying that smoking is harmful to health,

but where is the harm? Why is it harmful? Many people don't really

understand it.

Tobacco smoke contains more than 7,000 chemicals, of which 69 are known

carcinogens. Thousands of scientific proofs that smoking and second-hand

smoke are important risk factors for the morbidity and mortality of lung cancer,

chronic respiratory diseases, coronary heart disease, stroke and many other

diseases.

Smoking is a disease. In medicine, smoking is a chronic nicotine dependence

addiction disease, also known as nicotine dependence syndrome.

Smoking is only harmful to yourself, not to others, is that true?

The harm of smoking and inhaling second-hand and third-hand smoke to us also requires everyone to face

up to it. No matter how tobacco is used, it is harmful to the healthy population of users and even non-smokers,

and there are no harmless tobacco products.

Even inhaling small amounts of tobacco smoke can be harmful to the human body. A complete ban on smoking

indoors is the only effective way to avoid harm.
