first of all, dont become a probation officer. i would not recommend it. anyway, i have been on probation and have passed using the dilution method that is posted on the sticky. i m a heavy smoker and i even passed when my po called me in for a random test. i smoked the day before and thought i was outta luck, but followed the directions to the dilution method and passed. mind you the test was in the afternoon and i voided like 15-20 times before and drank water, no detox drinks, and gatorade or the same. also, the test they use are dip tests and are not sent to a lab.....for your job they will be very thorough and use a lab so you should stop smoking all together and work out, berries, water, 100% juices and creatine. good luck....and once again dont be a po, be something else. but whatever
