I prefer the synthetic route because you can keep it with you just in case you get hit with a random.
killerweed420 Reviewed by killerweed420 on . Freeze my own urine or use synthetic? I have been out of work for 4 months now, and have only been on 3 interviews out of about 100 Resumes that I have sent out. I also stopped smoking about 3 months ago and my own urine is totally clean right now. I was wondering if there would be an advantage to freezing my own urine for substitution instead of using the synthetic urine that comes with most of the substitution kits. Basically, I want to start smoking again, if possible, while waiting for the next interview to come along. Is Rating: 5
