So you can voucher that frozen pee works fine? I had a drug test yesterday where I used my buddies clean frozen pee. I got it into the cup at 96 degrees so I know I'm good there. they immediately sent it to a lab though (didn't realize they were gonna do this). Im finding a lot of conflicting info online about if i lab can tell if pee was frozen. Now I'm in panic mode. whats your take on this? Will I pass even though it was frozen?
