Passive smoking – the effects
• Fatal risks– Several hundred lung cancers (UK)– Several thousand heart disease cases
• Non-fatal impacts– Lung function, cough, wheeze, phlegm– Asthma aggravation
• Children– SIDS, middle ear infection, lung disease– 17,000 under-5s
• Other effects
ASH
Action on Smoking and Health
• “compelling confirmation” that passive smoke is a cause of lung cancer
• Excess risk of lung cancer 24%
• Corresponds to 100s of deaths in the UK annually
Passive smoking evidence – Hackshaw et al.
Risk of lung cancer: non-smoking women living with smoker compared to non-smoker

Addiction to nicotine
• Defeats the ‘choice’ argument– 83% of UK smokers would not start if they
had their time again
• Policy implications – Justifies treatment of tobacco dependence– Explains why ‘lights’ do not work– Product regulation and harm reduction
