【关于吸烟的危害英语作文（初中英语作文）】Smoking is a bad habit that can do a lot of harm to our health. Many people think that smoking is cool or helpful, but in fact, it brings more problems than benefits.

First of all, smoking is very harmful to the body. It can cause many serious diseases, such as lung cancer, heart disease, and even stroke. The smoke from cigarettes contains many dangerous chemicals, which are bad for our lungs and other organs. If you smoke every day, your health will get worse over time.

Secondly, smoking is not only bad for the smoker, but also for those around them. Secondhand smoke can harm non-smokers, especially children and the elderly. They may suffer from respiratory problems or other illnesses because of the smoke. That's why many places now have rules against smoking in public places.

Thirdly, smoking is expensive. A pack of cigarettes costs a lot of money, and if you smoke every day, this can add up quickly. This money could be used for something more useful, like studying or saving for the future.

In conclusion, smoking is a dangerous habit that harms both the person who smokes and others around them. We should try to avoid smoking and encourage others to quit. If we want to live a healthy life, we must say no to smoking.
