Science shapes every part of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning podcast about tiny things — from molecules to microbes — that have a big and often surprising impact on society. From deadly diseases to forensic toxicology to the search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its place in history and today, and how it could impact our world’s future. New episodes every Wednesday. Tiny Matters is brought to you by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude.

Vaping vs. smoking: What does decades of research tell us?
E-cigarettes, commonly referred to as “vapes,” were invented in the early 2000s with the explicit goal of helping people quit smoking by transitioning them to something safer. But there are many people, particularly in the United States, who start vaping without ever having smoked a cigarette, leading to fears that vaping will be an on-ramp to smoking — a “gateway drug.” In fact, in the U.S. alone, nearly half a million middle school students vape. And in 2019, the CDC started receiving reports of severe and acute lung injury in people who vaped. By February of 2020, almost 3,000 people had been hospitalized and 68 people had died. We know that smoking is deadly (in fact, it’s estimated to take about 10 years off your life), but of course vaping isn’t risk free. In this episode of Tiny Matters, we’ll dive into the science behind both to answer, “What’s more dangerous, smoking or vaping?” “And does vaping actually help people quit smoking cigarettes?” We’ll also get to the bottom of why so many people got sick or died from vaping back in 2019 and 2020, yet we haven’t seen injuries like that since.
