New regulations related to the sale of vaping products came into force in the UK this May, many of which are good for the consumer. All e-cigarettes and e-liquid refills need to include safety warnings, for example, and be tamperproof. But the laws also take into account the addictive nature of nicotine, and thus impose strict restrictions on the volume of e-liquid refills and maximum nicotine concentration, among other things. Depending on what happens with Brexit, though, one day we might not be beholden to the EU's Tobacco Products Directive. Public Health England believes this hypothetical scenario could present an opportunity to draft rules that acknowledge vaping, to some extent, as a healthier alternative to smoke.

The body also recommends that companies should not "routinely" include e-cigarettes as part of their no smoking policies. In other words, they should decide whether spaces actually need to be vape-free zones as well as smoke-free zones, rather than counting all methods of nicotine delivery as equal. As part of the Tobacco Control Plan, the UK's Medicines and Healthcare products Regulatory Agency (MHRA) will also make sure its review process "is fit for purpose" so that more e-cigarettes might be approved and made available through the NHS as smoking cessation aids.
