No Smoking

1. Smoking is harmful. It not only harms human health, but also has a negative impact on society. As long as any organized organism still has signs of life, it must breathe, exhale carbon dioxide in the body, inhale oxygen in the air, and carry out metabolism to maintain normal life activities. Non-smokers can inhale a lot of fresh air every day; but people who smoke often do not enjoy the blessings of nature. What they inhale is not fresh air, but toxic gases polluted by smoke.

2. Tobacco leaves contain the toxic substance nicotine, also called nicotine. One gram of nicotine can poison 300 rabbits or 500 mice. If a person is injected with 50 milligrams of nicotine, it will cause death.

3. Smoking is the most harmful to the respiratory tract and can easily cause laryngitis, tracheitis, emphysema and other diseases. When smoking, smoke enters the mouth, passes through the throat, trachea, bronchi, and enters the blood.
