Dky5 19 smoking is a very common phenomenon in today's society. From elderly grandparents to teenagers, they are constantly taking the poison of "chronic suicide".

The outer package of every cigarette says: Smoking is harmful to health. It is reported that millions of people in the world die of various diseases every year, among which smokers account for about 25%. This is by no means a small number. O A's "chronic killer" is only eight or nine centimeters long, but it is so heartless. O In order to prevent such a tragedy from happening again in the next century, the United Nations has set up a "Quit Smoking Day", and countries have successively formulated their own "cigarette laws". To control the growth of death population, o smoking is not only harmful to smokers themselves, but also harmful to people around them, because the smoke from smoking is still harmful to non-smokers and more harmful than smokers. This is called passive smoking. O While protecting our own health, we should also protect our living environment, because the smoke released by cigarettes is toxic. It contains a lot of harmful gases such as carbon dioxide, which is one of the important reasons for air pollution in public places. O So in order to protect our home, we should start with teenagers and me and carry out extensive and in-depth publicity on smoking restriction and smoke-free: For everyone's health, please don't smoke!
