In my view, smoking is not good for health. If a person who has the habit of smoking then he or she can have breathing, lungs and heart problems. The smoke of cigarette is also very harmful for health. If people smoke in public places then it is not only injurious for the smoker but also for others who do not smoke. For a healthy life, smoking is not good. The smoke of cigarette has toxic metals like Cadmium. If human body contains excess of cadmium then it creates many health problems like bone and heart diseases. For the safety of humans it is necessary to ban smoking in public and office buildings.
