I am a smoker but I do believe that the ban on smoking in pubs was a very good thing. I have worked in pubs for many years now and nothing was worse than being around the smell of fag smoke for eight hours a day! I know I sound like a hypocrite but the fumes of 60 people smoking in a pub is awful. Smoking is a personal choice so why inflict the fumes and smell on people that do not smoke! Second hand smoke is known to be just as bad for your health as smoking. So choosing to smoke around people that do not smoke is in a way morally wrong because you could be passing on future health risks to people you don't even know!
I have included a link to the cancer research site which gives info on passive smoking at its dangers.
