Actually, I agree with you on that. There's a consensus on first hand smoke being bad for you and anyone left arguing that actually smoking isn't bad for you (and there are some people still willing to argue this) either has their head in the sand or their snout in a trough.

The case for second hand smoke being bad for you is far less cut and dried at this stage. Certainly second hand smoke is bad for you, that's just common sense, but whether we ingest it in suficient quantities to have any noticable effect is far from proven. In the UK I think that the move ban smoking in pubs and clubs seemed to me to be driven more by political expediancy than by scientific analysis. That said, as a non smoker, I don't regret the ban. It means my nights out tend to be a bit more enjoyable than they were.
