Most dangerous seconf hand smoke by the way, doesn't come from cigarettes.... some comes from selfish barbecues which we are forced to breath in.

You are just posting to aggravate now!!!! And what about street bbqs on China, which are being cracked down on in China now at last. I like to eat bbq, but it is not like every house in the UK is having a bbq every day is it not? The climate just does not allow for it?! You just post drivel to antagonize, claiming cigarette smoke is harmless, talk to some real qualified doctors, working as a manager in telesales does not count.
