Can urine be tested for drugs?

Yes you can but it is risky. You can use clean friends urine or buy a synthetic. Make sure what your friend has consumed last 48 hours. You will try to take the sample in the room with you (some use condoms or balloons), but the main thing here is to keep the urine between 91 and 97 degrees. Don't forget to have a pin in your pocket and never, never throw or flush the used stuff away. Most of the time the lab assistant tells you to keep the door unlock and little open so she can hear do you really pee. She doesn't look only listen, blah.
