A new 'safer' e-cigarette that has all the flavour of tobacco but less harmful smoke has been developed by researchers.
The new device combines vaping technology with fresh tobacco as an alternative to nicotine liquids, currently on the market.
Flavourings are an important part of the vaping experience, but currently available e-cig flavours are food grade and the tobacco flavourings are unsatisfactory, researchers said.
This hybrid technology delivers a natural tobacco flavour without having to directly heat or burn the tobacco.
This eliminates many of the toxins that would be produced by excessive heating or burning of the tobacco leaf, researchers at British American Tobacco, who are developing the device, said.

The glo iFUSE device involves a heated coil warming an e-liquid to create a vapour that is drawn over a bed of blended tobacco with every puff.
The aerosol cools from around 35C (95F) to 32C (89F) as it passes over the tobacco, and the resulting energy exchange draws tobacco flavours from the tobacco into the vapour.
Sensory testing confirmed that the tobacco flavours were detectable.
And a comprehensive chemical comparison revealed that the vapour produced was almost indistinguishable from the parent e-cig vapour, which suggests that the tobacco blend is not adding any toxicants, researchers said.
Principal scientist Dr Ian Fearon said: 'E-cigarettes have proven hugely popular, but one size does not fit all, which is why we are developing a range of innovative tobacco and nicotine products, in addition to e-cigarettes, to give consumers a greater choice of less risky products.'
The chemical comparison was made between the vapour produced by glo iFUSE, a commercial e-cigarette Vype ePen and a 3R4F reference cigarette.
Up to 113 compounds of interest were targeted by advanced chemical analyses.
Among them, twenty nine compounds were measured on a per puff basis for all three aerosols.
A reduction of at least 98 per cent for all 29 compounds was recorded for both glo iFUSE and Vype ePen, compared to the reference cigarette.
There were small amounts of some aldehydes, semi-volatile compounds and phenolic compounds present in the aerosol and negligible amounts tobacco-specific nitrosamines compared to the reference cigarette.
In most cases, the vapour produced by the hybrid product, glo iFUSE, was indistinguishable from that produced by the e-cigarette.
Public Health England reports e-cigarettes are 95 per cent safer than cigarettes.
The findings were presented at the 22nd Annual Meeting of the Society for Research in Nicotine and Tobacco in Chicago.
