Is Tobacco Harmful Beyond Burning?

For decades, nicotine has been synonymous with smoking and disease but recently people are claiming nicotine patches have been improving their health—so what’s the truth? In this fascinating conversation, Vanderbilt neuroscientist and psychiatrist Dr. Paul Newhouse dives into the science to reveal the surprising ways nicotine impacts the brain, from Alzheimer’s and ADHD to depression and long COVID.

In this episode, we unpack:

• Why nicotine is not the same as tobacco
• What the groundbreaking MIND Trial shows about nicotine and Alzheimer’s
• Whether nicotine can improve focus, memory, or ADHD symptoms
• How nicotine may regulate mood, depression, and anxiety
• Surprising effects on weight, hormones, and blood pressure
• The truth about nicotine addiction, delivery methods, and dosage

✨ This episode completely changed how I think about nicotine and its potential role in modern medicine. It’s a powerful reminder to question assumptions and dig into the science behind our health beliefs.

✨ Homework: Write down one “health fact” you’ve always accepted as true—then do a little research to see if the science actually supports it.
