Receptor Subtypes and Cognitive Effects

Nicotine isn’t just addictive—it might be one of the most misunderstood nootropics in modern medicine. In this masterclass, you’ll learn how controlled, low-dose nicotine may enhance brain performance, boost neuroplasticity, improve mitochondrial function, and potentially extend lifespan. Host Dave Asprey breaks down the surprising science behind this controversial compound, separating fact from fear—and exposing the real risks that nobody talks about.

You’ll discover how nicotine affects neurotransmitters, why it may help with ADHD and focus, and how it compares to other cognitive enhancers like caffeine, nootropics, and even smart drugs. Dave explores how nicotine can be used to hack metabolism, enhance sleep optimization, and support fasting or ketosis protocols—if used properly. 

He also reveals the forms of nicotine that are safest (spoiler: it’s not vapes or cigarettes), how nicotine works at the receptor level, and what the science says about long-term health effects. This episode blends functional medicine, brain optimization, and biohacking into one powerful, myth-busting breakdown. 

You’ll Learn: 

• How nicotine affects mitochondria, neurotransmitters, and dopamine signaling 

• Why nicotine may boost neuroplasticity, memory, and attention span 

• How low-dose nicotine compares to caffeine, modafinil, and other nootropics 

• The safest delivery forms (and the ones to avoid) 

• Whether nicotine supports or hinders longevity and cognitive resilience 

• How it can be stacked with supplements, fasting, or ketosis 

• What functional medicine says about chronic use, addiction, and withdrawal 

This is essential listening for anyone serious about biohacking, human performance, and longevity, and for those who want to understand how functional biology and mitochondrial science are redefining recovery, energy, and aging.
