DUI drugs charges can be a source of confusion for defendants and lawyers alike. This article will explore these laws and explain their meaning, what must be proven, how they are proven, and how to defend against them.
There are three ways to charge DUI Drugs cases: (1) DUI Drugs – Less Safe; (2) DUI Drugs – Per Se; and (3) DUI Drugs – Combined Effect.
DUI Drugs – Less Safe
Georgia law prohibits a person from driving a vehicle while under the influence of any drug to the extent that it is less safe for the person to drive. O.C.G.A. 40-6-391(a)(2). This “less safe” statute requires proof (beyond a reasonable doubt) that the quantity or amount of the prescribed, illicit, or even over-the-counter drug in the person’s system caused impairment or rendered the person to be a “less safe driver.” Therefore, a person can be prosecuted even though the drugs were legally prescribed or were provided over-the-counter, so long as consuming those drugs caused you to be a less safe driver.
The “less safe” provision is the most common way DUI drugs charges are prosecuted. The State is not required to prove the accused had a particular level of drugs in their system. As a result, the State may prosecute even though no chemical test exists. The arresting officer will look for the following indications of impairment:
- Admitting to using drugs
- Bloodshot or watery eyes
- Slurred or slow speech
- Presence of drugs in vehicle or on person
- Bad driving
- Poor performance on Standardized Field Sobriety Tests
The key to defending these “less safe” drugs cases is raising doubt as to whether the drugs taken were the actual cause of the bad driving complained of. This causation element is something the State is required to prove. There are many reasons for bad driving unrelated to the consumption of drugs. In addition, defense counsel should raise challenges to the arresting officer’s training and experience in detecting and investigating DUI Drugs cases. In many instances, the arresting officer does not have the degree of training required to properly investigate these cases such as an officer who is qualified as a Drug Recognition Expert (DRE). Furthermore, defense counsel should raise a Harper challenge to the scientific validity of the Romberg Field Sobriety test if that test was performed by the accused. 
DUI Drugs – Per Se
Georgia law makes it illegal for a person to operate a vehicle while there is any amount of marijuana or a controlled substance, as defined in O.C.G.A. § 16-13-21, present in the person’s blood or urine, or both, including the metabolites and derivatives of each or both without regard to whether any alcohol is present in the person’s breath or blood. O.C.G.A. 40-6-391(a)(6).
Given the language of the law, the mere presence of a drug (prescribed or not) will constitute a violation of this code section. The question becomes how an arresting officer would know whether the accused had a valid prescription or not? Without an admission, this would be difficult for a prosecutor to prove.
Issues of proof aside, Love v. State, 271 Ga. 398 (1999), has essentially wiped out the “DUI Drugs – Per Se” law entirely. The Love case held that O.C.G.A. § 40-6-391(a)(6), was too broadly drawn, as it incriminates both legal and non-legal users of marijuana, constituting a violation of the Equal Protection clause of both the Georgia and United States Constitutions. This is the primary reason most DUI Drugs cases are prosecuted as “Less Safe” cases.
What remains of the DUI Drugs – Per Se statute is to punish those cases where someone is driving with drugs in their system which offer no lawful use (cocaine, heroin, etc.).
DUI Drugs – Combined Influence
Under O.C.G.A. § 40-6-391(a)(4), a person is prohibited from driving a vehicle while under the influence of any two or more of the substances provided in the DUI code section (alcohol, drugs, or toxic vapors) to the extent it is less safe for the person to drive.
Again, we see the State being required to prove the accused was a less safe driver because of the combined effects of two or more intoxicants (alcohol and drugs – prescribed or not). Although these cases present greater challenges, a skilled attorney can raise doubt as to whether the combined effect of intoxicants actually caused less safe driving.

 The Romberg test consists of the subject tilting their head back, closing their eyes, and counting in their head until the subject believes thirty seconds has elapsed and then telling the officer when they believe those thirty seconds had elapsed.
