Detection windows are approximate
Drug detection windows published on this site are approximate. Real-world detection times vary with substance, dose, frequency of use, individual physiology, hydration, body composition, and the laboratory's cutoff. Published windows are not predictive of whether a specific test on a specific person will return a specific result.
A drug test is not an impairment test
Workplace drug tests detect the presence of a drug or metabolite above the laboratory's cutoff. They do not measure impairment. This distinction matters especially for cannabis (THC), where the urinary metabolite (THC-COOH) can persist days to weeks after any psychoactive effect has ended.
If you have findings of concern
If you or someone you care about has received a result or has substance use concerns, please contact a qualified clinician. The SAMHSA National Helpline is free, confidential, and available 24/7 in English and Spanish: 1-800-662-HELP (4357).
