Apart from the differences in the level of nicotine, these cigarettes are close to the therapeutic product vaporizer invented ten years ago in China. This means that electronic cigarettes should carry the CE mark and nicotine cartridges must be registered as a medicinal product before being placed on sale.
This method is also supported by Denmark, Hungary, Portugal, Estonia, Germany and Slovakia. In Belgium and Luxembourg if the extract contains snuff recharge it is considered a product of snuff, while if it only contains nicotine it is regulated as a drug.
In some cases, the law may turn out to be striking: in Hong Kong, for example, the sale or possession of electronic cigarettes that have nicotine load can lead to a $100,000 fine and/or imprisonment for 2 years. This is because nicotine is classified as a poison. However, the “vaporizer” without this substance itself is allowed.
