Smoking is bad for health. It is a very serious problem in our society. Many people, especially men, like to smoke. But they don't know that smoking is very harmful to their bodies.

First, smoking can cause many diseases. For example, it can lead to lung cancer, heart disease, and other serious illnesses. These diseases are very dangerous and may even kill people. Second, smoking not only harms the smoker but also affects others. When people smoke, the smoke goes into the air and makes it dirty. Others who breathe in the smoke can get sick too. This is called secondhand smoke, and it is very harmful to children and elderly people.

In addition, smoking is very expensive. A pack of cigarettes costs a lot of money. If people spend this money on smoking, they have less money for other important things like food, clothes, or education. Also, smoking can make people feel tired and weak. It can affect their work and study.

As students, we should say no to smoking. We need to protect our health and live a healthy life. We can also tell others about the dangers of smoking and encourage them to quit. If more people stop smoking, our society will be better and healthier.

In conclusion, smoking is very bad for health. We should avoid it and help others do the same. Only then can we live a happy and healthy life.
