I had to do a 24 hour urine collection test this past week for one of my doctors. I ended up having to do it twice because the first time I used a regular tupperware food container since my doctor never gave/ didn't tell me I needed a special container. The container I used the second time had a special acid in it (at least that's what the technician who gave it to me said) to help preserve the urine. I don't know if urine used in a drug test needs to be preserved as I've never had one, but it might be something to look into. Wouldn't that suck to get caught using old urine.

Storing piss hey im clean right now and am planning to piss in a jar, store it outside in the snow, and smoke this weekend. im going to be tested next week and i was wondering if my clean piss will still be useable by then? im assuming the temperature wont ever get above 45, and it's gonna be burried in the snow. i cant use my fridge or freezer because its just too risky, living with my parents.
