1, happy as a fairy without a cigarette.

2. Make your lungs clearer.

3, the smoke is faint, the lungs are cold, and nicotine does not return.

There are many hazards of adolescent smoking, such as decreased lung function, decreased attention and inattention in study or work, which are all hazards of smoking.

But in real life, I feel that teenagers smoke more, especially now many female students smoke. Many people who really know the harm of smoking refuse to smoke or quit smoking, but teenagers who see smoking in their lives are still more common, so the harm is more.
