Driver stopped on outstanding arrest warrant. Police notice odor of freshly burnt marijuana emanating from vehicle and driver and find small amount of drug in door panel pocket. Police allege driver is lethargic with glassy, red, bloodshot eyes. Arresting officers are not “drug recognition experts” certified in drugged driving detection or special validated field testing for this purpose. OUI Drugs charge dismissed due to lack of evidence of erratic operation and lack of expert testimony.
