Smoking is harmful, not only to human health but also to society. As long as there are signs of life, any organized organism must breathe, exhale carbon dioxide in the body, inhale oxygen in the air, and carry out metabolism to maintain normal life activities.

Passive smoking means that people who live and work around smokers unconsciously inhale smoke, dust particles and various toxic substances. According to an international sampling survey, 50% of cancer patients caused by smoking are passive smokers.

The misunderstanding of smoking

Smoking less will not affect your health. This is a very common idea, but it is wrong, because smoking itself is a process of toxin accumulation, and everyone's physique is different, and the time of outbreak is not necessarily.

Many people think that the biggest harm of smoking is nicotine. In fact, nicotine can only make people physically and psychologically dependent. What really hurts is tar, smoke, carbon monoxide and so on. For example, tar produced by incomplete combustion of cigarettes contains 16 carcinogens and a mixture of more than 4,000 hydrocarbons and sulfides.
