Tobacco is the number 1 cause of preventable early death. You can not change your age or your parents but you can choose to not smoke or stop. Most smokers become addicted as teenagers before they know better. Tobacco (nicotine) is one of the most addictive substances known. It is easier to get people off heroin than nicotine. Governments are addicted to the taxes they make from tobacco. They say they want it to stop but do they? Premature deaths save governments from paying for health care (think less people on Medicare and social security). If they wanted to they could ban cigarette sales tomorrow. The majority of people are too lazy to grow and roll their own cigarettes (especially teens). Cigarette companies know if you can't get teens addicted it is not a profitable business model.
