ya or the freezer... ever seen American Beauty? the guy with the camera had to take drug tests and kept his nurses urine in the freezer, pulled it out a day before the test, and used it. its a movie so idk, might not work but thats ur best bet im guessing,..

GOOD LUCK
UMrocksmysocks Reviewed by UMrocksmysocks on . How long does urine keep? Ok, so i went for a test over the weekend, and failed horribly. I don really wanna stop smokin, especially now that i've got 2 months of holiday. So i was wondering, does anyone know if i can keep clean urine (friends urine or whatever) in an airtight container for like a week or 2? I just wanna keep it in case i get a suprise test Rating: 5
