Did you take anything to clean out your urine? I had to take one a few weeks ago and I had taken e, c and smoked a lot of weed just that weekend before and the test was on Wednesday, plus I smoke weed on the regular and I took some crap it was like an orange shake it started with a Z I can't remember I am burnt. But it worked totally cleeeeeen.
Good Luck by the way why did you have to take the test?
