Despite the lack of harmful chemicals and evidence to suggest passive 2nd hand vapour presents a danger, there are plenty of places where vaping is restricted. Here in the UK, train station platforms, airports and public transport have all banned vaping and the use of e-cigarettes. Workplace regulations are individual from place to place, though in Wales, e-cigarette use is now included in existing bans on smoking in workplaces and other public areas. Other businesses like restaurants and bars include vaping in their ‘no smoking’ rules, so customers and employees alike must observe them or risk being asked to leave.
