The global vaping sector faces a number of regulatory challenges that could drastically change the industry and have serious consequences for public health. In the United States, outgoing Food and Drug Administration (FDA) commissioner Scott Gottlieb has proposed new restrictions on e-cigarettes and vaping. If these proposals become law, retailers across the country could be subject to aggressive restrictions. Some flavoured e-cigarette products will no longer be sold at all, while others will be sold ‘only in a manner that prevents youth access’.
