We see that proof for an Atlanta marijuana DUI often rests on different types of indicators than an alcohol case. Odor may be noted by officers, but hemp scent can look identical to marijuana, so that single observation carries limited weight.
Field assessments play a larger role when chemical tools are unavailable. We watch how a driver responds to walk-and-turn or one-leg-stand tasks, and we scrutinize whether fatigue, medical conditions, or footwear could explain poor performance.
Unlike alcohol impairment, the classic involuntary eye jerk measured in the horizontal gaze test generally does not show up with cannabis. That means the state cannot rely on that particular ocular sign as it might in an alcohol matter.
Blood testing can identify cannabinoids, yet those metabolites can linger long after any impairing effect ends. We challenge whether a positive result actually proves the current inability to operate a vehicle safely under Georgia law.
Police may use Drug Recognition Evaluators, but their observations are often less reliable than laboratory science. We question procedure: whether officers had lawful grounds for the stop, whether consent or a warrant governed any blood draw, and whether testing followed proper chain-of-custody and analytical methods.
We, as an Atlanta marijuana DUI defense team, focus on these distinctions whenever we represent clients facing marijuana DUI charges. We press the state to prove impairment beyond a reasonable doubt, not merely the presence of a substance.
