Dr. Brady Smith (Dentist) – shares how smoking and nicotine impact your teeth, gums, and oral health long term. We cover it all: Cigarettes vs. cigars vs. weed Vaping (nicotine and THC) and why the “unregulated” side is so dangerous Popcorn lung, emphysema, COPD, and other risks Whether nicotine alone is harmful or helpful The reality of nicotine pouches like Zyn How frequency and dosage change the equation 👉 This is your masterclass episode on nicotine, smoking, and vaping—the risks, the potential upsides, and the uncomfortable truths most people don’t want to admit. 🔔 Don’t forget to subscribe so you never miss future episodes. 📩 Got questions or personal experiences with nicotine/vaping?
