Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, whether his Department (a) is aware of all substances used in vaping liquids and (b) has assessed the safety of all such substances.

Electronic cigarettes and nicotine-containing refill containers (e-liquids) are regulated under the Tobacco and Related Product Regulations 2016. A notification must be submitted to the Medicines and Healthcare products Regulatory Agency (MHRA) for each product prior to launch. This must include a list of ingredients and information on their toxicology and emissions.

The regulations prohibit ingredients that cause harm to human health, including respiratory sensitisers and substances known to cause cancer, cause mutation in cells or are toxic to reproduction. The notifier bears full responsibility for the quality and safety of their product and the MHRA checks all notifications to ensure the absence of prohibited substances.
