What is the detection window for marijuana?

Marijuana can remain detectable in the body for a variable period after use, depending on how often someone uses and what test is used. In common urine screening, THC metabolites can be detected from a couple of days after a single use up to several weeks in regular users, with many screens showing detection up to about three weeks for typical patterns of use. So a window of 2 days to 3 weeks best reflects the broad range you might encounter in standard testing scenarios, accommodating both occasional use and more frequent use. Shorter windows like 2-3 days would miss longer persistence in regular users, while longer windows such as 14-30 days are less representative for many screens, and 1-2 weeks misses some longer detections in heavier users.
