Many people like smoking, but I think it's very bad behavior. Convenient store can buy the tobacco leaf, its means it's easy to buy it. Thought the staff will let you shoe your credentials, it's haven't effect in reduce the smoking people's amount. Smoking will let people more and unhealthier. The heavy smoker's probability of got cancers is higher than standard. It's harmful to our body. Even thought the box of tobacco may print the pictures that people got cancer, but the heavy smoker doesn't care it. The most things to them are tobacco. I hate the smell of tobacco; it's will make me short of breathe. So I am gratified that there have no people smoke in my family. They don't harm themselves. My older brother told me when he is in army, someone tried alluring he smoke, but he reject, he think the health is the most important thing in the world, and the smell of tobacco is not good. I think smoking should be quick in the public place, because it is not that every can accept the un comfortable smell. If every heavy smoker smoking in the public street, we well smell it in the corner, but it's harmful to our body.
