In regards to drug tests...I tested our clients, usually parolee's/supervised probation/diversion/house arrest, they had to drop random UA's and they had to be supervised. As in there is nothing but you, the client, the specimen cup, paperwork, and toilet paper. For females they had to keep one hand visible at all times during the collection process and I'm pretty sure it was the same for males. They would receive call from the "color line" if their assigned color was given they had to come in and drop. If the person knows they have a set date with any officer of the court, they know there is the possibility they may have to drop a UA and they'll flush their system. Amphetamines leave the body within a fairly short time 24-48 hours. You wouldn't believe some of the things people would do to get out of being tested if they know they're dirty. As long as there is no reason for his parole officer to doubt his "good boy" act then more than likely he wasn't randomly testing and would have him drop while he came in for his normal monthly or quarterly check-in. Typically my experience is they have the person drop randomly from release up to 12 mo after release. All of that is based on my own experience with house arrest/criminal justice, it could be different in AR.
