In the United Kingdom, e-cigarettes are allowed and regulated under national tobacco and nicotine product laws. However, recent legislation bans the supply, offer to supply, and possession for supply of disposable or single-use e-cigarettes. Health benefit claims promoting e-cigarettes as smoking cessation aids are permitted, provided they are evidence-based and compliant with relevant regulations. Advertising of these products is allowed but strictly regulated. E-cigarettes can be legally purchased online and are commonly available in general retail outlets. Currently, there are no excise taxes levied on e-cigarette products in the UK.
The United Kingdom has a comprehensive regulatory framework around e-cigarettes. Based on that, product notifications are required before market entry, and child-resistant, tamper-proof containers are mandatory. Additionally, health warnings must appear on all packaging, and sales are restricted to individuals aged 18 years and above. E-liquids should not exceed a nicotine concentration of 20 mg/ml, and tank sizes are limited to 2 ml or less. While there are no restrictions on flavour range, vaping in public places is regulated and subject to local policies.
