Vaping could pose a greater risk to health than traditional cigarettes, potentially leading to dementia, heart disease, and organ failure, according to the author of a pioneering study. This is despite the NHS's stance that inhaling nicotine vapour from E-cigarettes is "significantly less harmful than smoking".

World's first study shows side-effects of vaping. Should restrictions go further? Or is this all to be expected? Join in the conversation.

Dr Maxime Boidin, who is spearheading the world's first controlled study into the long-term effects of vaping at Manchester Metropolitan University, set to conclude in March, warned that the risks for vapers may be even more severe.

He said: "Smokers tend to go outside and smoke, and once a cigarette is finished they have to light up another to keep going. But with vapes, you just keep going and it's much harder to know how many puffs you've had. It's much easier to vape continuously because you can do it in places where smoking might be less acceptable."

Dr Boidin added: "What we have found is the dangers for someone who keeps vaping are no different from smokers. At the beginning (of the study) I also believed that vaping was more beneficial than smoking.

"You see a lot more people vaping these days because they don't think it's too bad. Many will be horrified to know the truth."

The research, carried out at the university's Institute of Sport, involved participants aged between 18 to 45, with an average age of 27, who had similar fitness and physical activity levels. They underwent regular stress tests to assess the elasticity of their blood vessels and the rate of blood flow to their brains, as reported by........
