The world’s leading vaping brand is planning a significant UK expansion, including the marketing of fruit flavours that critics have said are designed to appeal to teenagers. Juul, which has been stocked in Boots, Sainsbury’s and specialist e-cigarette stores since last July, now intends to offer its products in around 55,000 British outlets, the company has confirmed. Among the flavours it will offer more widely are apple, mango and berries, despite ceasing selling these products in the US following an outcry that they were luring young people into vaping.
