I went through UMD random drug testing for about a year and a half starting in the fall of 2001. At the time, it was set up like this:Twice a week it is your responsibility to call a phone number and listen to a reading of a bunch of numbers on an answering machine. If your number is called, you went to the health center that afternoon. This part seemed to be varying on my way out of the program, but often we had to change into a doctor's office paper robe, before peeing into a cup. When you first entered the program, you would be called twice a semester, but this number is adjusted depending on behaviour, etc. As if this is not fun enough, each piss test costs the pisser $40.I did not smoke once for that year and a half on drug testing, though it was inevitable that once in a while I forgot to call in. One of the few days I didn't call in during the first year, my number was called. Not having even realized what I had done, I got a call from the judicial office later that week asking me to come in for a meeting. Going into it having no clue what it was about, I was sadly disappointed when it turned out to be a meeting to bust my balls and try to catch me in an attempt to cheat my way through the system. I left the office with an extra half year of random drug testing added onto my original punishment for smoking one joint on campus, though I had never smoked since.
