Health effects: popcorn lung, metals, inflammation

Big Tobacco's playbook is back — just with better branding and candy flavors. Jessica Wynn clears the air about vaping here on Skeptical Sunday!

Welcome to Skeptical Sunday, a special edition of The Jordan Harbinger Show where Jordan and a guest break down a topic that you may have never thought about, open things up, and debunk common misconceptions. This time around, we’re joined by writer and researcher Jessica Wynn!

On This Week's Skeptical Sunday:

• Vapes don't produce harmless vapor. They emit aerosol, a "chemical soup" containing nicotine, heavy metals like lead and nickel, formaldehyde, and ultrafine particles that penetrate deep into lungs where filtration is impossible.
• JUUL revolutionized addiction by using nicotine salts instead of freebase nicotine — lowering the pH for smoother hits at higher concentrations, delivering a faster brain rush with less coughing, and packing one pod with the equivalent of an entire pack of cigarettes.
• Many vapes labeled "nicotine-free" actually contain nicotine when tested, and secondhand aerosol isn't safe either — it deposits residue on surfaces, harms pets, and exposes bystanders to the same toxic cocktail inhaled by the vaper.
• The same playbook Big Tobacco used for decades — targeting kids, using candy flavors, buying off scientists, and fighting regulation — is now deployed through sleeker devices and better branding.
• Quitting is possible, and the tools actually work. Programs like the Truth Initiative's "This Is Quitting" show 40% higher quit rates, and texting DITCHVAPE to 88709 connects you with free, judgment-free support designed for real people fighting real addiction.
