In August, the North Carolina Supreme Court weighed in on drug identification once again in State v. Osborne, ___ N.C. ___ (August 16, 2019). I wrote about the earlier Court of Appeals decision in the case, here. The new Osborne decision clarifies the application of drug identification rules as well as sufficiency of the evidence in this context.

Back in February, I blogged about State v. Bridges, ___ N.C. App. ___, 810 S.E.2d 365 (Feb. 6, 2018), and drug identification. In short, Bridges held that the defendant’s out-of-court admission to an officer that a substance was “meth” was sufficient to meet the State’s burden of proving the identity of the substance, at least where the defendant failed to object to the testimony. This decision arguably signified an expansion of the Nabors exception to the Ward rule that a chemical analysis is generally required to establish drug identity (subject to other exceptions covered in the post). For a more thorough review of the topic, see that previous post. The Court of Appeals recently decided another drug ID case, State v. Osborne, ___ N.C. App. ___ (October 2, 2018), adding a new wrinkle to the rules.

The easiest way for the State to prove impairment in a prosecution for impaired driving is by introducing the results of a test of the defendant’s breath. Such test results are admissible without the foundation that would otherwise be required for this kind of scientific evidence so long as the testing was carried out in accordance with statutory and administrative rules governing implied consent testing. G.S. 20-139.1(b). Because the rule allowing breath test results to be introduced into evidence is relied upon so often, I thought it might be helpful to review the admissibility rule and the requirements for such tests.

No legislative session would be complete without amendments to the state’s DWI laws. The 2016 short session upholds this tradition by amending the procedures that govern the admissibility of chemical analyses in impaired driving trials in district and superior court.
