When my second cousin was on probation, she had this bag she hid under the sink so she could pass all of her drug tests. She did. I'm wondering what all would be involved in a pee kit. Im almost certain it involved yellow dye, but other than that I'm clueless. I don't think she used fake pee, because her officer did the tests randomly on his weekly visits, so she never knew when it was going to happen. I'm asking only out of curiosity and not out of personal need.
