Smoking has become a common practice among people all over the world. It's a very dangerous habit and may cause cancer, heart attack, high blood pressure and other serious illnesses. One puff of cigarette smoke contains fifteen billion particles of matter including nicotine, alcohol, carbon monoxide, arsenic and several other acids. These are all injurious to our health. Nicotine obstructs the normal flow of blood. The dangers of smoking are many and that's why we all should avoid it to live a healthy life.
