In the UK, it is illegal for anyone under the age of 18 to purchase or use e-cigarettes or vaping products. This includes both the purchase of vaping devices and the use of vaping products, whether with nicotine or without.
It is also illegal to purchase vaping products on behalf of someone under the age of 18. Vendors are required to verify the age of customers, and they can face fines or other penalties if they are found to have sold vaping products to minors.
The UK government and public health officials recommend that young people under the age of 18 should not use e-cigarettes or other vaping products, as nicotine can be harmful to developing brains and there is still much that is unknown about the long-term health effects of vaping.
