how long does it take a drug test to come back
Answers. Best Answer: Depending on what they test for, it can take a couple of weeks. Usually they can put a strip in your urine to test for t.h.c. If you still have the paper work you can call them to find out.If you come back postitive for anything, a doctor will call you. had to take a urine drug test for my employer.
