Well, I don't know how they do it in the UK, or anywhere else, for that matter, but here in the NYC, we have king Bloomberg (he seems to have managed to have himself elected mayor for life, no matter how I vote against him at every election), and king Bloomberg does not like cigarettes and/or cigarette smoke. And that's fine, he's entitled to dislike something...but because king Bloomberg feels his likes and dislikes are the only ones of importance, so he suggested that smoking be banned in all public places (a public place being anywhere outside of one's own home), and all the anti-smoking idiots jumped on that bandwagon, and in the time it takes to find your lighter, smoking became banned in all public places here in NYC.
The other thing king Bloomberg has done is to impose a heavy tax on cigarettes, on all tobacco products, really...now, mind you, this man is a billionaire in his own right, he doesn't need the salary he gets for being mayor of this city, he doesn't need the tax dollars he collects from me every time I buy a pack of cigarettes. Truth be told, I would not be here complaining about the taxes if the tax from the cigarettes was being put to something useful (like, say, FIXING THE POTHOLES IN THE ROAD), but sadly king Bloomberg has chosen to park that tax money somewhere (under the royal mattress, perhaps) and we who live and smoke here pay the heavy tax and still have the potholes.
The point of all this, if there is a point, is that the heavy tax (with all the taxes, a pack of cigarettes costs $10 here, and yes, that's $10 US) and the ban on smoking in public, this smoker has not even considered quitting.
As for the "graphic warnings" they've been threatening to put on the packs of cigarettes, those warnings may deter very young people from starting, possibly. But I'm a 34 year old, 4 pack a day smoker...my pack of cigarettes is the boss of me, and has been for quite some time. Not only do I already know that smoking will cause my lungs to become ruined, but I WELCOME the ruin of my lungs.
