They can enforce it. They put him on probation and he has to report daily for urine analysis and breathalyzer tests. My son was put on antabuse, a drug that they crushed and he had to inhale in their presence. The drug causes the person to have a severe physical reaction to alcohol. One beer produces heart-attack like symptoms. More than that, and you need to go to the emergency room. My son was on it for 6 months. He only tried to drink with it once.
