An essential clarification to begin with ... Contrary to popular belief, nicotine is not carcinogenic ; its consumption with an electronic cigarette is therefore risk free. The only risk is choosing the wrong dosage when you start vaping. A rate too high is likely to cause headaches or palpitations. And too low will inevitably lead to a feeling of withdrawal and, in the long run, to a relapse.

In e-liquids, the dosage is expressed in milligrams per millilitre (mg/ml) and varies from 0 to 20 mg/ml, in as required by the European directive on tobacco products.

To increase the chances of success when you quit smoking, it’s important to first evaluate the degree of dependence through one's consumption habits. A heavy smoker, for example (more than a pack a day), would be well advised to choose a liquid with a dose between 16 and 20 mg/ml in order to have his daily nicotine. Nevertheless, other parameters, such as the power of the electronic cigarette and the nature of the liquid should be considered. The most judicious solution : evaluate your nicotine satisfaction during the first few days of vaping and, if necessary, adjust the dosage accordingly ; the objective being to gradually reduce consumption over the months, but above all without rushing.
