No, frozen and thawed urine works fine and urine can be frozen for up to 1 year. Hope that helps, and IMO, you have nothing to worry about from second hand smoke. N2
IamN2pot Reviewed by IamN2pot on . Drug Test Blues...? Hey guys, sorry to say I am NOT a smoker. I have never placed bong, pipe, joint, or blunt to my lips ever, nor have i eaten anything containing weed. My question is, this weekend, I was hanging out with alot of my friends, they are all smokers and yet i still have no urge to try it. Anyway we were in a very small back room in a trailer, 5 people (not including self) smoking up heavily with a pipe. Smoke was blown in my face, i inhaled it multiple times on accident, coughing and such. I knew Rating: 5
