Elux 3500 Disposable Vapes are illegal in the UK if they contain nicotine, due to the amount of nicotine-containing e-liquid within the device (10ml), and UK Law states that they’re only allowed a maximum of 2ml. However, nicotine free Elux 3500 vapes are legal as there are no restrictions on the amount of 0mg vape juice contained in them.If you want to use the same great flavours that you love for longer, with nicotine, the best substitute would be the Elux Legend nic salt vape liquids.
