Most smokers want to give up. An important percentage of them try without any kind of professional help, which often leads to a high number of relapses. One of the main reasons for these attempts without treatment is due to the frequent lack of access to such treatment. However, the progress seen in new technology has led to an increase in research and creation of remote tobacco addiction treatment programmes, with Internet being one of the frameworks offering the best prospects in this field. Thus, and based on a depth of prior experience in face-to-face treatments and a previous remote treatment project through the service's own quitline, the Tobacco Addiction Unit at Carlos III Hospital developed the Online Tobacco Addiction Unit "Life without Tobacco"; the start-up, methodology and results of which are presented in this article.
