In 2017, the TRPR (Tobacco and Related Products Regulations), which was a revised interpretation of the EU Commission's TPD (Tobacco Products Directive), came into effect in the UK. This piece of legislation aimed to ensure the safety of vape products include vape kits and included the limitations of nicotine-containing e-liquid bottles to 10ml, vape tank sizes to 2ml as well as nicotine strength of e-liquid to a maximum of 20mg. Current UK laws state the sale of e-cigarettes and e-liquids is legal to over 18s only, but many shops allow minors over the age of 12 to purchase nicotine-free e-liquid as all the ingredients in it are safe compared to nicotine e-liquid. Technically it is illegal for a minor to purchase any vaping products or any items associated with e-cigarettes but it is perfectly legal for a minor to use an e-cigarette, nicotine or nicotine-free. These are UK laws only.
