Understanding Cotinine and Its Impact
Cotinine is a metabolite of nicotine, the addictive substance found in tobacco products. When you smoke or use nicotine products, cotinine is produced and can be detected in your body for varying periods of time. The half-life of cotinine in the human body is approximately 16-20 hours, meaning that it takes about 16-20 hours for half of the cotinine in your system to be eliminated.
| Detection Method | Cotinine Detection Duration |
|---|---|
| Saliva | Up to 4 days |
| Urine | Up to 3 weeks |
| Blood | Up to 3 days |
| Hair | Up to 90 days |
Factors Influencing Cotinine Elimination
The length of time cotinine stays in your system can vary depending on several factors, including:
| Factor | Impact on Cotinine Elimination |
|---|---|
| Smoking Frequency | Heavy smokers have higher cotinine levels and longer detection times |
| Age | Cotinine is metabolized more slowly in older adults |
| Metabolism | Individuals with faster metabolisms eliminate cotinine more quickly |
| Body Fat Percentage | Cotinine can accumulate in body fat, extending its detection time |
| Exercise | Regular exercise can speed up cotinine elimination |
