The limited number of studies conducted to date indicate that the risk of passive exposure to electronic cigarette vapour is small relative to tobacco cigarettes. Further research was, however, recommended to evaluate the impact of e-cigarettes on indoor air quality and to estimate any possible effects of passive inhalation of e-cigarette vapour. There is no research assessing the risks to health in small confined spaces, such as cars.
No estimate has been made of the cost of prescribing licensed e-cigarettes. Any e-cigarette licensed as a medicine would be treated as a nicotine replacement therapy (NRT) in accordance with the National Institute for Health and Care Excellence public health guidance on smoking harm reduction. The revised European Union Tobacco Products Directive makes provision for e-cigarettes not subject to medicines licensing to be regulated as consumer goods with specific requirements set out in the directive.
The current cost of prescribing NRT on the national health service can be found in the Prescription Cost Analysis section of the NHS Business Services website at:
