DUI is NOT limited to just alcohol. A DUI is driving under the influence of alcohol and/or drugs. That includes marijuana! Yes, the judge could order a UA, if he/she has reasonable cause to believe you are in violation. Non-compliance with the court's order is reasonable cause. If your UA comes up dirty, you will probably go to jail. It is ultimately up to the judge.
