In the Netherlands there has been a lot of turmoil around the smoking ban in bars and restaurants introduced on July 1st 2008. Main objective was a healthier work environment for personnel. In Scotland they showed that a ban really improves experienced health in workers:
Bar workers in Scotland reported significantly fewer respiratory and sensory symptoms 1 year after their working environment became smoke free. As these improvements, controlled for seasonal variations, were seen in both non-smokers and smokers, smoke-free working environments may have potentially important benefits even for smokers.
Objective: To examine changes in the health of bar workers after smoke-free legislation was introduced.
Design: Longitudinal study following bar workers from before legislation introduction, at 2 months after introduction and at 1 year to control for seasonal differences.
Setting: Bars across a range of socio-economic settings in Scotland.
Participants: 371 bar workers recruited from 72 bars.
Intervention: Introduction of smoke-free legislation prohibiting smoking in enclosed public places, including bars.
Main outcomes measures: Change in prevalence of self-reported respiratory and sensory symptoms.
Results: Of the 191 (51%) workers seen at 1-year follow-up, the percentage reporting any respiratory symptom fell from 69% to 57% (p = 0.02) and for sensory symptoms from 75% to 64% (p = 0.02) following reductions in exposure, effects being greater at 2 months, probably partly due to seasonal effects.
Excluding respondents who reported having a cold at either baseline or 1 year, the reduction in respiratory symptoms was similar although greater for “any” sensory symptom (69% falling to 54%, p = 0.011).
For non-smokers (n = 57) the reductions in reported symptoms were significant for phlegm production (32% to 14%, p = 0.011) and red/irritated eyes (44% to 18%, p = 0.001).
Wheeze (48% to 31%, p = 0.006) and breathlessness (42% to 29%, p = 0.038) improved significantly in smokers. There was no relationship between change in salivary cotinine levels and change in symptoms.

Great post. thanks for sharing it here. These information will be more helpful for the people to no more about the bad effects of smoking. I too was a good smoker it caused lot of bad effect for my health and mind. Later I came to know about thoughtsbecomereality.co.uk which helped me through various hypnotherapy techniques and hypnosis to stop smoking. Hypnosis increase my self control and confidence.
