As a reformed smoker I have to say I was absolutely delighted when the ban came into effect over here. I believe you guys have it now in the UK?
Interestingly enough this is the only topic that I disagreed with Penn and Teller on. They are for smoking in public places. Again, they see it as the whole "personal freedom" issue. They also say that there is no conclusive proof that second hand smoke can cause cancer (which I don't agree with incidentally).
Personally, I've no problem with people smoking (although I think it's very dangerous habit) as long as it not in an enclosed public space. Smoke in you own home, sure. But not in a bar or restaurant. Use the sheltered beer gardens that are now provided!
When the ban was coming over here, everyone said it would be "the end of all pubs" (that slippery slope again)

. Well, you can bet you ass the Irish 'arnt giving up their drink that easy.Yep, there was a decline, but that was because people felt they were being ripped off by the landlords (who upped the priced with the euro). So people started to drink at home before they would go out.
Just my tuppence worth...
