To me, it doesn't make sense for big tobacco companies to invest heavily, like they have, in a product that is currently used primarily to get people to stop buying their products. The FDA will never approve vaping as a smoking cessation method. That is reserved for BP. Smokers now have a social stigma attached to them that was typically reserved for child pornographers. That isn't going to change and big tobacco has to see the writing on the wall that they are basically on their last generation of customers. People have enjoyed tobacco for centuries. I think people still want to enjoy the sensation that tobacco can bring, but they are now more likely to start using illegal drugs than cigarettes. Cigars are pricey, take a long time to finish, and can really only be enjoyed in wide open spaces. Dip, chew, and snuff have never been practical for the masses. I think many are looking at e-cigs as a way to generate new business and not just replace the old business. I think the day will come where there will be more e-cig customers than there are currently cigarette customers.
