Question to the Department of Health and Social Care:

To ask the Secretary of State for Health, what research his Department has assessed or commissioned on whether e-cigarette vapour carries health risks to bystanders.

The Department has not to date directly commissioned any research on this topic but is keeping the research that has been done under review.

The studies that have been conducted to date indicate that the risk of passive exposure to electronic cigarette vapour is small relative to tobacco cigarettes.
