All of theses points have lead me to come up with this idea:
What if one of the big tabacco companies like Philip Morris or British America Tabacco flipped their business model and instead of selling cigaretts that cause addiction, they started selling highly branded batches, gums and inhalers to help current smokers quit. In effect, they make the image of quitting smoking as popular as smoking was in the beginning of last century. The marketing value of a cigarette company radically changing its tactics in this way could be the biggest move to stop people from smoking and say many lives and would generate enough income to sustain the tabacco companies, at least for a while.
