Youngsters using e-cigarettes more likely to go on to smoke, research finds

Nearly 40% of teenagers who used e-cigarettes went on to smoke real cigarettes, new research published in JAMA Pediatric has revealed. The American researchers found that 38% of e-cigarette users had started smoking traditional cigarettes within a year of starting, compared to only 10% who had not used an e-cigarette.Recent research has suggested that vaping could be a way of breaking the habit and could save the NHS millions. Yet the US study indicates that as e-cigarettes deliver nicotine more slowly than traditional cigarettes, users advance to cigarette smoking as they become tolerant of nicotine side effects.Dr Brian Primack of
