Smoking is a habit of taking smoke from tobacco-made materials like cigarette, biri, heroin etc. It is a dangerous habit. People generally smoke to find pleasure for the time being. Some smoke only as a fashion which later turns into a habit. Many young people just try to imitate seniors and some are addicted by the influence of bad companions. However, taking smoke for few days for just curiosity is the starting of smoking habit formation. Very soon, one becomes addicted to smoking. Smoking is harmful to human health. Our younger generation is becoming addicted to smoking without knowing what damages they are causing to their health. It may cause cancer, heart attack, bronchitis, numbness, loss of memory etc. One puff of cigarette smoke contains a huge amount of injurious matters like nicotine, carbon monoxide, methyl alcohol and many other harmful elements. Nicotine obstructs the flow of blood through veins. This reduces the supply of oxygen in our body. As a result, blood pressure rises and heart beat increases, which cause heart attack. Besides, carbon monoxide of tobacco smoke absorbs the oxygen from our blood. Thus, smoking poisons our body slowly. Smoking is equally harmful to a non-smoker who stays beside a smoker. So, the younger generation should avoid smoking cigarettes. Our government should take initiative to stop smoking. Young people should be made conscious of the pernicious effects of smoking. In order to avoid the attraction of smoking, they can engage themselves in games and sports, helping the poor and constructive work for our society.
