For anyone to make the claim cigarettes are not addictive they would have to ignore an incredible amount of evidence to the contrary. I have co-workers and friends who smoke, and will brave an element to satisfy their craving. These are not stupid people, and most have gone to some extraordinary lengths to quit. Yet for all we know about this, cigarettes remain legal and readily available.
At some point you have to look at the system and make the obvious observation - it is still serving interests that are not in keeping with reality. Next you have to ask why, followed by WHO is responsible. We jail drug dealers based on the assumption that what they sell COULD kill people, while big tobacco continues to deal a drug we KNOW for a FACT kills people. It is pretty glaringly obvious the prolific killer has used his deep pockets to grease all the right wheels. At what point do we as a people identify these shoddy wheels, remove them and replace them with wheels that work? How long will this silent killer enjoy protected status at our expense?
Personally, I would rather see the lobbyists, politicians and corporate architects for the continued use of tobacco behind bars, and let the pot dealers go.
