Passive smoking harms non-smokers

Extensive research evidence clearly demonstrates that passive or involuntary exposure to tobacco smoke causes death, disease and disability including cardiovascular disease, lung cancer, and lung diseases such as emphysema, bronchitis and asthma. It has been shown that lifelong non-smokers with partners who smoke in the home have around a 20-30% greater risk of lung cancer than other non-smokers, and those exposed to cigarette smoke in the workplace have a 16-19% increased risk. Tobacco smoke is very effective at harming both smokers and exposed non-smokers.
