Nicotine addiction is a global health issue, affecting millions of people who smoke cigarettes or use vaping products. In episode 90 of the Huberman Lab Podcast, the topic revolves around how nicotine impacts our brain and body, and practical strategies for those looking to quit smoking or vaping.
**Effects of Nicotine on the Brain**
Nicotine acts as a stimulant in the brain. It binds to acetylcholine receptors, which are part of the cholinergic system involved in arousal, attention, mood, and other neurobiological functions. When nicotine binds to these receptors, it triggers the release of several neurotransmitters including dopamine, which enhances pleasure and mood-modulating effects. This increase in dopamine is a key factor in the development of nicotine addiction.
The podcast highlights that chronic exposure to nicotine alters the balance and function of neurotransmitters in the brain. It can lead to changes in cognitive functions such as focus, memory retention, and overall mental health. Over time, the brain becomes dependent on nicotine for maintaining these neurotransmitter levels, leading to addiction.
**Effects of Nicotine on the Body**
Beyond its effects on the brain, nicotine also poses several risks to physical health. It increases heart rate and blood pressure, posing risks for cardiovascular diseases. Nicotine can also constrict blood vessels causing reduced blood flow and promoting risk factors associated with stroke or heart attack.
