Breathing other people’s smoke is known as passive, involuntary or secondhand smoking (SHS). It can also be called ‘environmental tobacco smoke’.
Smokers and nonsmokers alike inhale SHS and this is an unavoidable consequence of being in a smoke-filled environment.
Exposure to SHS has immediate health effects. It can reduce lung function; exacerbate respiratory problems; trigger asthma attacks; reduce coronary blood flow; irritate eyes; and cause headaches, coughs, sore throats, dizziness and nausea. There is no safe level of exposure to tobacco smoke and there are long-term health effects, including heart disease and lung cancer, especially with continued exposure over time.
In response to these health risks and growing public demand for smokefree public places, most nations have passed laws to minimise citizens’ exposure to secondhand smoke. Since 2007, smoking in enclosed public places has been prohibited throughout the UK. Regulations to prohibit smoking in cars when children are present entered into force on 1 October 2015 in England and Wales. Similar regulations are due to be implemented in Scotland and Northern Ireland.
Article 8 of the Framework Convention on Tobacco Control requires nations that have ratified the treaty to implement effective measures to protect people from secondhand smoke.
Guidelines on implementing Article 8 were adopted unanimously in 2007. These outline the requirement that countries should adopt comprehensive smokefree laws without exemptions or ventilation systems in all enclosed public places and workplaces.
