State v. Colquitt, ___ Wash. App. ___, 2006 Wash. App. LEXIS 1383 (Jun. 29, 2006) ("The agreement Colquitt entered into to participate in drug court was neither a stipulation that the substance in the underlying charge was a controlled substance, nor a stipulation to the sufficiency of the evidence. And, although he agreed that the police report that included a field test of the substance could be admitted, there were no laboratory test results. We hold that the police report and field test were not sufficient evidence of a controlled substance. We reverse and remand to vacate the conviction.").
