It is a hopeful sign though there is an interesting backslide recently. I continue to be surprised and disappointed in seeing young people smoke. My family in Chicago has a number of smokers, including among my nephews and nieces. It is particularly surprising given the extremely high price of packs today. That of course is the value of an addictive product.
The trend nationally is more promising than the results in my family. Traditional tobacco sales are down roughly 30 percent but E-cig sales are climbing by an impressive 25 percent annually.
