Took a real test to day. at 20ng. I passed!!! after 22 days of not smoking, on top of many years of the chronic, every day, many times a day. I did a dilution, Gatorade , aspirin. The pecker checker watching, told me twice ( as he looked on, hope he loves his job), top of the stream not mid-stream. so I did. After he did his checks on it, and passed, he had me dump it, I asked if I could keep it since it was a good one and use it again, He didn't think it was funny, I guess checking pee and looking at dicks all day, you lose your sense of humor.
