Vaping: Does It Really Cause Cancer?

April 23, 2026 · 43 min

Show notes

Headlines have been screaming about a new study suggesting that vaping could cause cancer — and that vaping could be just as dangerous as cigarettes. And if this were true, it would be a HUGE deal. We’ve been hearing for years that vaping is a safer option — and can help you quit ciggies. But the new paper has run up against angry criticisms from other scientists, with some calling the paper "misleading" and "problematic." So what’s going on?? Do scientists still think vaping is safer than cigarettes? How well do vapes actually help people quit smoking? And could Big Tobacco be behind the scenes, clouding the truth about all of this?? We get help sorting it out from Professor Bernard Stewart, Professor Lion Shahab and Professor Becky Freeman.
