[Vaping: a new strategy to prevent smoking-related diseases?].

By quitting, smokers of all ages can gain substantial health benefits. No other single effort of public health is able to achieve an advantage comparable to smoking cessation on a large scale. However, conventional approaches to smoking cessation require tobacco users to completely abstain, and many smokers are unable - or have not the willingness - to achieve this goal, and then continue to smoke despite the looming negative consequences for health. But it is possible to consider another option: the reduction of harm caused by tobacco smoking (tobacco harm reduction) through the intake of nicotine from alternative sources safer than tobacco smoke, such as the electronic cigarette (e-cig). It is a promising product for the reduction of harm caused by tobacco smoking. In addition to providing nicotine through the vapour without the typical toxic and carcinogenic substances derived from combustion, the e-cig is also a good substitute for the rituals associated with the behaviour of the smoker. In this article, the author suggests that the wide dissemination of vaping behaviour can become a successful strategy to reduce smoking and preventing smoking-related diseases, advancing on how to succeed with this matter.
