In the United Kingdom, smoking is legally permitted, with certain conditions set from laws enacted separately in England, Wales, Scotland and Northern Ireland. It is illegal to smoke tobacco in enclosed public places, such as restaurants, shops or pubs, under the Health Act 2006 for England and Wales, the Smoking (Northern Ireland) Order 2006 for Northern Ireland and the Smoking, Health and Social Care (Scotland) Act 2005 for Scotland. It is also illegal to smoke in a car if one is transporting people under 18 or if a vehicle is being used for work purposes. Smoking is prevalent among a sizeable, but continuously reducing minority of the population. It has been argued that smoking puts considerable strain upon the NHS due to the health problems which can be directly linked with smoking. Su
