E-cigarettes are promoted in many countries as a safer alternative to tobacco. However, in the EU, there has been a long-running debate about the health effects of these products.

At the moment, they are covered by the Tobacco Product Directive as they contain nicotine. However, a new report says they could fall under pharmaceutical regulation in the future.
