Everyone knows smoking is bad for them, and they even know theyll save money if they quit, but since more people who are poor smoke than more affluent people, quitting smoking can mean huge savings that can be directed to more worthy and fulfilling pursuits. And since smoking causes serious disease, as well as less severe chronic illnesses like colds, quitting smoking will also reduce the costs of treating various illnesses, and hopefully reverse any advancing diseases like Emphysema or Lung Cancer etc.
