【Smoking（Is及Harmful(吸烟有害)英语口语演讲稿）】Good morning, everyone.

Today, I would like to talk about a serious issue that affects millions of people around the world — smoking. The title of my speech is "Smoking Is Harmful." Although it sounds simple, the message behind it is very important and needs to be understood by all of us.

First of all, let's think about what smoking does to our bodies. When someone smokes, they are putting harmful chemicals into their lungs. These chemicals can damage the respiratory system, making it harder to breathe and increasing the risk of diseases like lung cancer, chronic bronchitis, and emphysema. In fact, smoking is one of the leading causes of preventable death worldwide.

But the harm doesn't stop there. Smoking also affects other parts of the body. It increases the risk of heart disease, stroke, and even some types of cancer. For example, it can cause cancer in the mouth, throat, and bladder. The more you smoke, the higher your chances of getting these illnesses.

Another important point is that smoking not only harms the person who smokes but also those around them. Secondhand smoke is just as dangerous as smoking itself. People who live with smokers or work in environments where smoking is common are exposed to the same harmful chemicals. This can lead to health problems, especially for children and the elderly, who are more vulnerable.

In addition, smoking has a big impact on our daily lives. It costs money — a lot of money. Many people spend hundreds or even thousands of dollars each year on cigarettes. That’s money that could be used for something more valuable, like education, travel, or saving for the future.

Moreover, smoking can affect our appearance. It can cause yellow teeth, bad breath, and premature aging of the skin. These are things that many people don’t want to deal with, yet they are the result of a habit that seems harmless at first.

So why do people start smoking? Some might think it looks cool, others may try it out of curiosity, and some might feel pressured by friends. But once they get addicted, it's hard to quit. Nicotine is a powerful drug that makes people crave cigarettes again and again.

However, quitting is possible. Many people have successfully stopped smoking with the help of support groups, counseling, or nicotine replacement therapy. It's not easy, but it's worth it. Every day without smoking is a step toward better health.

In conclusion, smoking is harmful in many ways — to our health, our wallets, and the people around us. We should all be aware of these dangers and make informed choices. If you're a smoker, consider quitting. If you're not, avoid starting. Let’s take care of ourselves and others by staying away from tobacco.

Thank you for listening.
