present, many teenagers smoke. I don't think it's a good phenomenon. It must be
stopped, for smoking is harmful in many ways.
smoking is bad for our health. As we start smoking, it's so difficult to give
up, because the tobacco contains a drug called nicotine, which can get us into
the habit of smoking. When we go without nicotine, our bodies will feel sick.
smoking is so dangerous. When we smoke in bed, we may kill ourselves as well as
burn down our houses, for burning cigarette ends may cause a big fire. And if
we threw the cigarette ends anywhere, it would also cause a fire disaster.
