Seemingly-reliable sources give you diametrically-opposed views on vaping. Are e-cigarettes “95% less harmful” than cigarettes, or aren’t they? Are vapes gateway drugs that lead people to smoke, or are they a great way to give up smoking? Is it both? Neither?
In Episode 5 of The Studies Show, Tom and Stuart look into the research on the health effects of vaping and try to answer these questions - as well as explaining the origin of the fabled “popcorn lung”.
