Estimate your THC detection window
Get a rough estimate of how long THC may remain detectable in urine or blood, based on consumption frequency and last use. Not a lab test, not a statement on fitness to drive.
Days since last use7 days
Estimated window (urine, 50 ng/mL)10–21 days
3–14 more days until estimated clearance
Earliest clean from 08/07/2026, likely from 08/18/2026.
Estimates. Actual clearance depends on body weight, metabolism, body fat percentage, and consumption intensity. A lab test is essential for the MPU — this estimate does not replace a test.
