Teenagers all over the west (many of them) have been convinced that smoking pipes and cigarettes (which used to be depicted as sophisticated / glamorous / sexy / cool etc.) is a stupid, uncool thing to do.
Now the "cool" thing is marijuana / designer drugs / same sex intercourse etc, but that will also change.
If the bought and paid for media will cooperate, many uses of cell phones can also be depicted as dumb: spending hours at a time chatting while your brain is next to a powerful microwave transmitter that messes up your DNA is NOT very smart.
