The UK's primary Public Health agency, Public Health England, recently published its review of ecigs in the UK. Its findings are now common knowledge, and, frequently in that document, Article 20 of the Tobacco Products Directive due for implementation in May 2016 is criticised. We call on the Department of Health and the UK Government to refuse to implement Article 20, as it will certainly result in nett harm to UK Public Health by preventing the uptake of effective ecigs by current smokers.
