Sir: I find it very strange how cool smoking is. May smokers do not understand why they smoke because even passive smoking can lead to lungs cancer. If you don’t care about your own lungs, atleast think about what you are doing to others. I would like to ask the prime minister and his cabinet to ban smoking and the scale of cigarettes in the country. Maybe they can try to ban smoking indoors like they have abroad or make cigarettes so expensive that people cannot afford to buy them. If they cannot, they should at Least make sure that no one under the age of 21 buys them. we need proper rules and regulations in place; otherwise God knows what will happen to our youth and environment.
