Yesterday an important new study of nicotine absorption from different types of electronic cigarettes was published in the journal Scientific Reports, by Dr Konstantinos Farsalinos and colleagues of the Onassis Cardiac Surgery Center in Greece. This study recruited 23 experienced electronic cigarette users (used for an average of 19 months after over 20 years of smoking), who attended the laboratory on 2 separate occasions, having abstained from nicotine for at least 8 hours each time. On one visit they were provided with “first generation” electronic cigarette: one that is a very similar size and shape as a traditional cigarette with a single low-capacity battery. On the other occasion they were provided with “new generation” electronic cigarette, with a larger battery and controls to regulate the power delivery to the battery. At each visit the e-cigarettes were filled with identical 18 mg/ml nicotine concentration liquid and the participants were instructed to take 10 puffs during the first 5 minutes of “vaping” and then to puff as they felt like it for the next hour.
