I move away from them. But when I' m in a restaurant and they do mind putting it out (which happened), do I have to take my dish and go outside?
Some of the immediate effects of passive smoking include eye irritation, headache, cough, sore throat, dizziness and nausea. Adults with asthma can experience a significant decline in lung function when exposed, while new cases of asthma may be induced in children whose parents smoke. Short term exposure to tobacco smoke also has a measurable effect on the heart in non-smokers. Just 30 minutes exposure is enough to reduce coronary blood flow.
In the longer term, passive smokers suffer an increased risk of a range of smoking-related diseases. Non-smokers who are exposed to passive smoking in the home, have a 25 per cent increased risk of heart disease and lung cancer. A major review by the Government-appointed Scientific Committee on Tobacco and Health (SCOTH) concluded that passive smoking is a cause of lung cancer and ischaemic heart disease in adult non-smokers, and a cause of respiratory disease, cot death, middle ear disease and asthmatic attacks in children. A more recent review of the health impacts of passive smoking by the International Agency for Research on Cancer (IARC) noted that "the evidence is sufficient to conclude that involuntary smoking is a cause of lung cancer in never smokers."
A study published in the British Medical Journal suggests that previous studies of the effects of passive smoking on the risk of heart disease may have been underestimated. The researchers found that blood cotinine levels among non-smokers were associated with a 50-60% increased risk of heart disease.

It's funny, all the people who "die" from cigarette smoking are always old and would probably be dying anyways from something else.
Whilst the relative health risks from passive smoking are small in comparison with those from active smoking, because the diseases are common, the overall health impact is large. The British Medical Association has conservatively estimated that secondhand smoke causes at least 1,000 deaths a year in the UK. However, the true figure is likely to be much higher. Professor Konrad Jamrozik of Imperial College London estimated that domestic exposure to secondhand smoke causes at least 3,600 deaths annually from lung cancer, heart disease and stroke combined, while exposure at work leads to approximately 700 deaths from these causes. Jamrozik also estimates 49 deaths - or about 1 a week - from exposure at work in the hospitality trades. In the population aged 65 or older, passive smoking is estimated to account for 16,900 deaths annually. 9,700 are due to stroke, where current evidence of health effects is weakest.
A distinction between old and young people was made.
Almost half of all children in the UK are exposed to tobacco smoke at home. Passive smoking increases the risk of lower respiratory tract infections such as bronchitis, pneumonia and bronchiolitis in children. One study found that in households where both parents smoke, young children have a 72 per cent increased risk of respiratory illnesses. Passive smoking causes a reduction in lung function and increased severity in the symptoms of asthma in children, and is a risk factor for new cases of asthma in children. Passive smoking is also associated with middle ear infection in children as well as possible cardiovascular impairment and behavioural problems.
Infants of parents who smoke are more likely to be admitted to hospital for bronchitis and pneumonia in the first year of life. More than 17,000 children under the age of five are admitted to hospital every year because of the effects of passive smoking. Passive smoking during childhood predisposes children to developing chronic obstructive airway disease and cancer as adults. 14 Exposure to tobacco smoke may also impair olfactory function in children. A Canadian study found that passive smoking reduced children' s ability to detect a wide variety of odours compared with children raised in non-smoking households. Passive smoking may also affect children?s mental development. A US study found deficits in reading and reasoning skills among children even at low levels of smoke exposure.
