In a DUI drugs case, the issues are very different from a typical alcohol-related DUI — and in many situations, they can be more complex for the State to prove.
Unlike alcohol cases, where there is a defined legal limit of 0.08%, there is no clear “legal limit” for most drugs in Georgia. Prosecutors must prove beyond a reasonable doubt that the driver was impaired to the extent that they were less safe to drive — and that can be challenging.
One important factor is that the standardized field sobriety tests commonly used by officers were originally developed and validated to detect alcohol impairment, not impairment from prescription medications or other drugs. There is no direct correlation in Georgia between those tests and a specific drug level for most substances. As a result, applying those same tests in a DUI drugs case can raise significant legal and scientific questions.
Another key issue is that many DUI drugs cases involve individuals who are taking lawfully prescribed medications. In some situations, a doctor has prescribed a medication specifically to improve a person’s health, stability, or overall functioning — not to impair them. Simply having a prescription medication in your system does not automatically mean you were driving unsafely.
DUI drugs cases often require a careful examination of the evidence, the science behind the testing, and the role of any prescribed medication. These cases are highly fact-specific, and the burden remains on the State to prove actual impairment beyond a reasonable doubt.
