Cousin third time smoking and being tested 5 days later

well over thanksgiving weekend i had some weed and my cousin wanted to smoke some with me so we did si we blazed on friday night and saturday we did just enough to get steady high going. well apparently he got injured on the job the other day and had to go to the hospital and they took a pee test. So for someone that was only there 3rd time ever and didn't do excessive amounts be safe in about 5 days? lol

No way to know for sure without testing.

Its possible. But chancy. If he did the dillution method the morning of the test he might of been ok.
