In 5 years when Cowtown catches up with the ROC this will all be for moot. Smokers will get tired of smoking outside in -30C weather...wont go to Restaurants or Bars and will eventually quit in order to stop being labelled.
Their children, educated on the inherant dangers of smoking will nag their puffing parents endlessly making their excuses seem childish in comparison to that of their pre-teen children.
Smoking kills...and comparing this to other bad habits is just silly.
