The mice did not inhale the vapor as deeply as a human would, for instance. One in four mice exposed to e-cigarette smoke developed lung cancer after a year - and more than half developed a pre-cursor to bladder cancer. “Our study results in mice were not meant to be compared to human disease, but instead argue that E-cig smoke must be more thoroughly studied before it is deemed safe or marketed that way.”. Tests in 2017 found vapers had 95% less in their blood than regular smokers - causing experts to publicly claim switching to vaping could save millions of lives. Something went wrong, please try again later. We want to hear from you.
