Lung cancer is the leading cause of cancer death. Governments say they want to prevent smoking and lung cancer but their actions show otherwise. Governments get rich from taxes on cigarettes. It would be easy for governments to make all cigarette sales illegal. People could still have the "freedom" to "grow tobacco and roll" their own if they want this "freedom". Putting the cigarette companies out of business would eliminate over 95% of smokers. Teens are too lazy to get addicted by having to grow and roll their own cigarettes. Big tobacco companies will continue to bribe politicians to keep this from happening. They get teens addicted when they are young and stupid and trying to fit in and prove they are "adults" by smoking with their friends. Smoking for as little as 2 years gets most teens addicted for life.

Ninety to ninety-five percent of lung cancer is from smoking or second-hand smoke. Every premature death from smoking (cancer, heart attacks, and strokes) is one less person the government has to pay social security benefits for the rest of their lives. Smoking addiction is a win-win situation for government (taxes and premature death with less social security payments). Governments can truly say smokers get addicted "of their own free will". How many teens do you know that would go to the trouble of growing and rolling their own cigarettes? Governments "facilitate" teens getting addicted by allowing legal production of cigarettes. Teens don't want "grown-ups" telling them what to do.

Smoking takes an average of 10 years off of your life expectancy.
