Smoking is a bad habit that does a lot of harm to human health. Cigarette smoking does great harm to human health. In many cases, cigarette has proved to be the direct cause of such a fatal disease as cancer-hence its nickname, Cancer Stick . Experts say that smoking one cigarette can reduce one s life by about 15 minutes and that chain smoking is far more hazardous. Recent findings of medical research show that even a tiny drop of nicotine can kill a large animal like a horse. Some medical reports have also proved that heavy smoking would seriously affect an adult s sexuality, and smoking after a meal also disturbs one s digestive system. Cigarette smoking not only jeopardizes the physical health of a smoker, it also affects the health of a nonsmoker who passively inhales the polluted air into his or her lungs when he or she is exposed to a winding shroud of cigarette smoke. The impact on such passive smokers , according to the experts in the medical field, can be even more damaging, and that is why smoking is usually prohibited in most public places.
