Vaping is either a public-health menace or a lifesaving tool—depending on who you ask. In this episode, we dive into the global tug-of-war over e-cigarettes, as countries from Belgium to New Zealand push bans and restrictions even while researchers insist vaping is far less harmful than smoking. We break down the real risks, from the EVALI outbreak linked to vitamin E acetate to the questionable chemicals found in legal vape mixes. And we explore the flip side: growing evidence that vaping can help smokers quit more effectively than traditional nicotine-replacement therapies. Caught between fear and potential, regulation and harm reduction, we ask: what role should vaping play in the future of public health?
