Some 70% of the population do not smoke. I heard my colleague Senator Bohan say that 70% of bar workers smoke, but surely the 30% of them who do not smoke have a right to clean air. I do not feel that is too much to ask for that 30% of non-smokers. I have no difficulty with a person's right to smoke, but I have a huge difficulty with the fact that so many non-smokers are harmed by passive smoking. There is well-established evidence regarding the very harmful effects of passive smoking on non-smokers. Passive smoking is the single biggest indoor air pollutant to which workers are exposed in the workplace.
