Introduction:
Electronic cigarettes and/or vapers are devices marketed to the public as a harmless and affordable substitute to combat the use of traditional cigarettes. Their easy accessibility and poor sales control is due to the fact that prior to their commercialization these products do not require rigorous tests that can guarantee the safety of their consumers. Most of the pathologies associated with the consumption of e-cigarettes are based on damage to the respiratory system (EVALI), cardiovascular system (venous and arterial system) and at the oral level (periodontitis). In addition to causing damage, it aggravates pathologies already present in patients, such as asthma or COPD.through a review of articles, the toxicity of e-cigarettes is evidenced, dispelling the myth that they are a good alternative to give up traditional cigarettes in a harmless and effective way.

Material and Methods:
For the preparation of this work, a bibliographic review was carried out in PubMed. Those studies that were discarded met the following exclusion criteria: articles related to the use of e-cigarettes for smoking cessation, as well as articles in which animals were used to demonstrate the negative effects and those in which there was a clear lack of information.

Results:
The total number of articles found was 9,849, of which 19 were finally chosen for the elaboration of the work. Filters and inclusion and exclusion criteria were applied, such as the time interval 2010-2022, in order to achieve a more exhaustive and concrete review of reviews about what we wish to convey. These studies talk about the problems associated with the use of e-cigarettes and vaping, as well as lung damage, such as EVALI and the oxidative and inflammatory damage they cause in our organism. They also tell us about other types of traumatic and thermal pathologies that can be caused along the respiratory and vascular system. Another very important aspect to be dealt with is the use of eliquids and flavoring that these devices use to achieve a greater affinity for people and the problems in the organism that they cause.

Conclusions:
Once all the information has been synthesized, it is possible to conclude the number of negative health effects that the use of e-cigarettes entails, regardless of the type of e-liquids used or whether or not they contain nicotine. However, these devices have become very popular in a very short period of time, which means that there is a great deal of ignorance about them and very few conclusive studies on the number of pathologies caused by them. From the nursing point of view, we have concluded that educational workshops could help to change the perspective of the young public regarding its consumption. Likewise, the increase in long-term research would be a fundamental piece to extend the current information about them. Political institutions have a great impact on society, so they should implement restrictions on the sale and purchase of electronic cigarettes and/or vapers, thus reducing consumption by the population
