E-cigarettes could soon be prescribed on the NHS in England to help people stop smoking tobacco products.
The Medicines and Healthcare Products Regulatory Agency is inviting manufacturers to submit goods for approval to be prescribed.
It could mean England becomes the first country in the world to prescribe e-cigarettes as a medical product.
There has been much debate over the years about whether e-cigarettes should be used for this purpose.
E-cigarettes are not completely risk-free but they carry a small fraction of the risk of cigarettes.
They do not produce tar or carbon monoxide, two of the most harmful elements in tobacco smoke.
The liquid, that is heated up to be inhaled, contains some potentially harmful chemicals also found in cigarette smoke but at much lower levels.
This aerosol is commonly referred to as vapour and so the use of an e-cigarette is described as vaping.
A medically licensed e-cigarette would have to pass even more rigorous safety checks than those required for them to be sold commercially.
