UK. New vaping regulations. New laws restricting the sales of e-liquids and e-cigarettes will “inevitably” push up the cost of vaping, a trade organisation has warned. Vaping devices are known for being cheaper than cigarettes and are designed as way to help smokers kick their habit. The key changes which come into force from 20 May 2017 include: Refillable tanks must have a capacity of no more than 2ml; E-liquids can not be sold in quantities greater than 10ml; Unless registered as a medicine e-liquids can not have a nicotine strength of more than 20mg/ml; E-liquid packaging must be child-resistant and tamper evident; Additives including colouring, caffeine and taurine are banned; All e-cigarettes and e-liquids must be registered with the Medicines and Healthcare Products Regulatory Agency before they can be sold; Stricter labelling requirements.
