True enough I suppose, although I do sometimes wonder about the rather lack-lustre attempts to stop people from smoking.
The already addicted are told "ooooh, its bad for you", but are neither given particular motivation or assistance to stop (without it costing them)
The *are soon going to be addicted* are disuaded by reaaly effective adverts on TV, which currently have some strange alien figure telling kids that smoking makes you less attractive (which would, from my experience of school seem to be wrong) and very little real encouragement to break the peer pressure motivation.
As for the *not going to be addicted* set, we aren't exactly catered for in any public place....
I suspect the reason it is not illigal is for the reasons you suggested, but the reason it is not seemingly frowned upon (like being drunk in public) is for reasons of economy.
Still, i might be wrong. It has happened on several other occsaions
