You did a little cocaine almost 5 days ago will you fail a urine drug test?

if you only used that night, and not any before or after, you should be good. coke is out in 72 hours. when i was in the military, when we had 4 day weekends, we couldn't smoke weed, for fear of pissing dirty on monday, so me and a buddy would split an 8 ball. i was always clean monday morning. just make sure to do it all that night, and dont buy more the next day! or u will be screwed.
