Abstract
The possible spread of the use of nicotine pouches (NP) in Spain is a cause for concern, as the global market for these products is growing significantly. Unlike pharmaceutical specialties containing nicotine, NP contain contaminants such as nitrosamines that pose an additional risk to the already known addictive and cardiovascular effects of nicotine. The tobacco multinationals that market the most widely used NP use behavioural and persuasive communication strategies to promote their consumption, taking advantage of the absence of regulations governing these products. Until new regulations are developed, it is important to develop information campaigns and preventive activities based on behavioural sciences and to make the risks of these new products known to professionals and users of the health system.
