It is not only actual smoking that kills. Even second-hand smoking kills! A study conducted by the Swedish National Board of Health and Welfare and Bloomberg Philanthrophies reveals that more than 6,00,000 people die yearly due to second-hand smoking, meaning those who are  near the smokers and getting the smoke in their lungs etc. The children and women are also affected in very large numbers. There is no other way but to completely stop smoking. No small small measures will do.
