<unk>  with cartridges<unk> s are a type of electronic cigarette used to vape nicotine through a mouthpiece connected to the body of the device by magnets. These devices are a newer generation of e-cigarettes that are often marketed to a younger crowd that do not wish to attract attention gained through regular e-cigarettes or traditional tobacco-burning cigarettes.<unk> s contain a disposable cartridge and have coils that cannot be removed or changed.<unk> s were designed to provide higher nicotine delivery with a smaller amount of power than conventional e-cigarettes. Refillable<unk> s can be filled with conventional freebase nicotine liquid or nicotine salts into the empty<unk>  cartridges with varying levels of nicotine often at 2.5% and a maximum of 6.0%. Although, in some countries such as the United Kingdom, the maximum legal limit of nicotine containing liquids is a concentration of 2% or 20mg/ml. The first to introduce<unk> s was Pax Labs in June 2015, and since then many companies began introducing similar products.
