The regulation applies for all types of electronic cigarettes which can be used for liquid with nicotine. This applies to both electronic cigarettes for single-use and electronic cigarettes, which can be refilled with nicotine-containing liquid. If the products have not been registered with the Danish Safety Technology Authority, they are illegal to sell. There is, however, an exemption if the products have been approved as medicinal products.
It is legal to sell electronic cigarettes and refillable containers with nicotine in Denmark, if the products have been registered with the Danish Safety Technology Authority.
