Cocaine detection windows at a glance
| Test type | Approximate detection window |
|---|---|
| Saliva (oral fluid) | ~1β2 days after use |
| Blood | Up to ~1β2 days |
| Urine | ~2β4 days (longer with heavy or repeated use) |
| Hair follicle | Up to ~90 days |
Why urine detects it longer than blood
Cocaine has a short half-life, so the drug itself clears fast. But the body converts it to benzoylecgonine, the marker most tests screen for, and that metabolite stays detectable in urine for a few days β longer than the effects last. Heavy or repeated use extends the window.
What affects the timing
- How much and how often β binge or heavy use lengthens detection
- Your metabolism and liver/kidney function
- Whether alcohol was also used β this can form a longer-lasting metabolite
- The test type and its cutoff
Choosing the right test
Cocaine is included in the standard 5-panel and 10-panel. For very recent use, saliva is ideal; for a 90-day history, use hair.
