smoked pot over 4 weeks ago but still test positive will have a urine test 2 days what can i do ?
How often were you smoking?

Are these home tests, dipsticks or other type of "instant" tests?

Why are you being drug tested?

up untill 10 weeks ago i was smoking heavily then only on weekends then none for 2 weeks then 5 weeks ago had some . tests were dipsticks.being tested for work

Thank you:

Dipstick tests rely on immunoassay technology that can give false positive tests for a number of reasons including common over-the-counter medications.

To get a true valid positive test, the specimen needs to be confimed with GC/MS (gas chromatography-mass spectrometry) technology at a laboratory.

Typical detection periods for marijuana are 10-15 days for daily use, and up to 30 days for heavy daily use. I suspect that your dipsticks are false positives.
