Yes. You can be charged with DUI for marijuana in Georgia, even if you did not drink alcohol. Georgia DUI law covers driving while under the influence of any drug to the extent that it is less safe for you to drive, and it also has a separate marijuana and controlled substance provision for blood or urine tests. A marijuana DUI case often turns on the traffic stop, officer observations, field sobriety testing, drug recognition evidence, and whether the state can connect test results to impaired driving. If you are facing this charge in Gainesville, Hall County, or nearby Georgia courts, early legal guidance can help you protect your license, your record, and your options.
Can You Get a DUI for Marijuana in Georgia? 
A marijuana DUI in Georgia can feel confusing because many people think DUI means alcohol only. Georgia law is broader. Under O.C.G.A. 40-6-391, prosecutors may pursue DUI when a person is accused of driving while under the influence of a drug to the extent that it is less safe for that person to drive. The same statute also addresses cases involving any amount of marijuana or a controlled substance in a blood or urine test, subject to statutory exceptions.
That means you do not need a breath test number, a beer can in the car, or an admission that you smoked recently for the state to bring a DUI charge. The case may be based on driving behavior, physical signs, statements, field tests, drug testing, or a combination of these factors.
For many drivers in Gainesville and Hall County, this type of arrest starts with something ordinary: drifting within a lane, speeding, failing to dim headlights, leaving a parking lot near a late-night restaurant, or passing through an area where officers are watching traffic closely. Once an officer suspects impairment, the stop can shift quickly from a traffic matter to a criminal investigation.

How Georgia Marijuana DUI Law Works
Georgia prosecutors usually look at marijuana DUI in two main ways.
First, the state may allege DUI drugs less safe. This means the accusation is not simply that marijuana was present. The state must prove that a drug made you a less safe driver. Evidence may include:
- The reason for the stop
• Odor of marijuana
• Red or glassy eyes
• Statements made during the stop
• Field sobriety test performance
• Body camera footage
• A drug recognition evaluation
• Blood or urine test results
Second, the state may rely on a marijuana or controlled substance test result under O.C.G.A. 40-6-391(a)(6). This part of the law is serious because marijuana metabolites may remain in a person’s system after the effects have worn off. That does not mean every test result proves unsafe driving. It does mean the defense needs to examine the testing, the timing, and the legal theory being used.

Is Marijuana Legal in Georgia?
Georgia has not legalized recreational marijuana. Possession, purchase, manufacture, distribution, or sale of marijuana remains addressed under Georgia’s controlled substances laws, including O.C.G.A. 16-13-30.
This matters in a DUI case because an officer who smells marijuana or finds suspected marijuana may investigate both DUI and drug possession. A single traffic stop can lead to multiple charges, such as DUI drugs, possession of marijuana, possession of a controlled substance, traffic violations, or child endangerment if a child under 14 is in the vehicle.
That does not mean every charge is valid. Officers still need a lawful basis for the stop, a lawful basis for expanding the investigation, and a lawful basis for any search. If drugs were found in a vehicle, questions about ownership, location, access, and knowledge may matter.

What Police Look for During a Marijuana DUI Stop
Marijuana DUI cases often depend on observations. Officers may note how you drive, how you speak, how you answer questions, and how you appear during the stop. They may ask when you last smoked or consumed an edible. They may ask where you are coming from, whether there are drugs in the car, or whether you will perform field sobriety tests.
You should be polite, provide your license and required documents, and avoid arguing on the roadside. You also have rights. You do not have to guess, explain, or make statements that could be used against you. The roadside is not the place to convince an officer that you are fine. The officer is usually gathering evidence.
Field sobriety tests can create problems because they are based on officer interpretation and are often recorded only from limited angles. Weather, footwear, nerves, medical issues, uneven pavement, fatigue, and unclear instructions can affect performance.

Blood and Urine Testing in Marijuana DUI Cases
Unlike alcohol cases, marijuana cases do not involve a simple breath number that claims to show a precise level of impairment. Blood or urine testing may show THC or metabolites, but the meaning of those results can be disputed.
The defense may examine several questions:
- Was implied consent read correctly?
• Did the officer have grounds to request chemical testing?
• Was the sample collected properly?
• Was the sample stored and transported correctly?
• Did the lab follow proper procedures?
• Did the result show active THC, inactive metabolite, or both?
• Can the state connect the result to your driving at the time of the stop?
These questions matter because a test result does not always tell the full story. Marijuana can affect people differently. Timing can be unclear. An edible, vape, or smoked product may create different facts. A person may also have health-related explanations for certain symptoms, even when Georgia law still treats recreational marijuana harshly.
Georgia allows drivers to challenge breath, blood, and other testing issues in DUI cases. A deeper discussion of testing challenges is available at https://www.brettwillislaw.com/can-you-challenge-the-results-of-a-dui-breathalyzer-or-blood-test-in-georgia.
SM was a well-known DJ who was stopped on I-85 and arrested for DUI, and his license was taken for a year. A few months later, he got another DUI in a different county. We helped get the second DUI reduced to Reckless Driving with only a $50 fine, and we proved the first officer had no right to stop him. Because of that, the first DUI was dismissed. JF parked at a Publix, police showed up and started bothering him and his friends. They tried to pressure him into letting them search his car, and when he said no, they claimed they saw a vape pen and searched anyway. JF was arrested & charged with several felonies. We filed a motion to suppress the evidence, and they dropped all the charges. Pam killed her longtime boyfriend with a knife one night in their apartment. Our investigation uncovered that Pam had long suffered physical and mental abuse at this man’s hands. Prior to trial, we were able to convince the prosecution agreed to dismiss the murder charges. Pam is now back home with her family.
What Happens After a Marijuana DUI Arrest?
After a marijuana DUI arrest in Georgia, you may face both criminal court consequences and license-related issues. The criminal side may involve booking, bond, an arraignment, motions, plea negotiations, trial preparation, and possible sentencing if there is a conviction. The driver’s license side may involve deadlines that move faster than the criminal case.
A first DUI conviction in Georgia can involve probation, fines, community service, DUI Risk Reduction Program requirements, license consequences, court costs, and other conditions. Repeat offenses bring harsher exposure. Marijuana-related facts can also create added complications if there are drug charges, alleged possession in the vehicle, or prior criminal history.
Your first court date may be in a municipal court, probate court, state court, or superior court depending on where the arrest occurred and what charges were filed. In Gainesville and Hall County cases, local procedures, prosecutor policies, officer availability, and court calendars can affect strategy.

Possible Defenses to a Georgia Marijuana DUI
No defense applies to every case. A strong defense starts with the facts, the videos, the reports, the testing records, and the law. In a marijuana DUI case, defense issues may include:
- The traffic stop was not legally justified.
• The officer extended the stop without enough cause.
• The search of the vehicle was unlawful.
• Field sobriety testing was unreliable.
• Officer observations were overstated or inconsistent with video.
• The state cannot prove impairment at the time of driving.
• The test result does not prove less safe driving.
• The sample collection or lab process has problems.
• Statements were taken in violation of your rights.
• The prosecution cannot connect you to drugs found in the vehicle.
Video evidence can be valuable. Dash camera and body camera footage may show whether the driving was truly unsafe, whether instructions were clear, whether the officer’s report matches what happened, and whether your balance, speech, and behavior were consistent with impairment.
