[E-cigarette and smoking cessation : current situation in Belgium].

Because of the devastating health effect of chronic burned tobacco inhalation, smoking cessation is a public health priority. After a short review of the validated pharmacological tools for smoking cessation we have analysed the clinical data obtained with the increasingly popular e-cigarette as an aid to help current smokers to quit. Although e-cigarette has not proved its effectiveness in smoking cessation yet, the public health authorities have usually adopted a pragmatic position. They recommend trying e-cigarette when validated pharmacological tools have failed in making patients abstinent, on the basis that e-cigarette is strongly assumed to be less toxic and may still help reducing the amount of smoked cigarettes.
