Nicotine Absorption: How It Enters the Body and Its Effects
How is nicotine absorbed into the body? Nicotine, the addictive substance found in tobacco products, enters the bloodstream through various routes, primarily through inhalation and ingestion. Understanding this process is crucial for comprehending nicotine's impact on the body.
Inhalation
- When you smoke, inhale, or vape tobacco products, nicotine is absorbed through the lungs' tiny air sacs called alveoli.
- The alveoli walls are extremely thin, facilitating the rapid diffusion of nicotine into the bloodstream.
| Inhalation Method | Nicotine Absorption Rate |
|---|---|
| Cigarettes | 90-95% |
| E-cigarettes | 50-70% |
| Hookah | 40-50% |
Ingestion
- Nicotine can also be absorbed through the lining of the mouth, throat, and stomach.
- This occurs when chewing tobacco or using nicotine gum, patches, or lozenges.
| Ingestion Method | Nicotine Absorption Rate |
|---|---|
| Chewing tobacco | 20-30% |
| Nicotine gum | 10-20% |
| Nicotine patches | 5-15% |
| Nicotine lozenges | 5-10% |
