Navigating Marijuana DUI Arrests in Nevada City, California

Before diving into the legal defenses, it’s important to have a basic understanding of California’s marijuana DUI laws. In California, it is illegal to drive under the influence of any drug, including marijuana. This means that if a police officer believes you are impaired by marijuana while driving, they can arrest you for a DUI.

However, unlike alcohol DUIs, there is no specific legal limit for marijuana in California. This means that even if you have a small amount of THC in your system, you can still be charged with a DUI. Additionally, unlike alcohol, marijuana can stay in your system for days or even weeks after use, making it difficult to determine if you were actually impaired while driving.

The ambiguity of marijuana impairment testing presents a unique challenge for drivers and law enforcement alike. Because THC metabolites can linger in the body long after the effects have worn off, individuals who consume cannabis responsibly may still face DUI charges despite not being impaired at the time of driving. This gray area allows for a range of defenses to be mounted in court.

Legal Defense Strategies for Marijuana DUI Arrests

While the laws surrounding marijuana DUIs in California may seem strict, there by are several legal defenses that can help you fight the charges. Here are the top legal defense strategies for marijuana DUI arrests in California.

Challenging the Validity of the Traffic Stop

The first step in any DUI case is for the police officer to have a valid reason to pull you over. If the officer did not have a valid reason to stop your vehicle, any evidence gathered after the stop may be thrown out in court. For example, if the officer did not observe any traffic violations but pulled you over because they suspected you were under the influence of marijuana, this could be considered an illegal stop.

Moreover, the defense can argue that the officer’s subjective belief of impairment is not sufficient to justify the stop without concrete evidence of erratic driving or a traffic violation. Documentation of the stop, including dashcam or bodycam footage, can be critical in establishing whether the officer had a legitimate reason to initiate the traffic stop.

Questioning the Accuracy of Field Sobriety Tests

Field sobriety tests are used by police officers to determine if a driver is impaired by marijuana. However, these tests are not always accurate and can be affected by various factors, such as weather conditions, poor lighting, and underlying medical conditions. If you can prove that the field sobriety tests were not conducted properly or were affected by external factors, it can weaken the prosecution’s case against you.

It’s also worth noting that standard field sobriety tests were designed to detect alcohol impairment, not drug impairment. This can be a critical point in your defense, as the physical and cognitive effects of marijuana differ from those of alcohol. An experienced attorney can challenge the officer’s interpretation of the test results, particularly if there’s a lack of evidence showing that these tests are valid indicators of marijuana impairment.

Disputing the Validity of the Breathalyzer Test

In California, breathalyzer tests are used to measure the blood alcohol content (BAC) of a driver suspected of a DUI. However, these tests are not accurate for measuring THC levels. If the police officer used a breathalyzer test to determine your level of impairment from marijuana, you may be able to challenge the validity of the test in court.

Breathalyzer tests for alcohol are based on a scientific understanding of how alcohol is metabolized and its presence in breath. Since THC is not present in breath in the same way, using a breathalyzer to determine marijuana impairment is fundamentally flawed. Your defense can emphasize the lack of correlation between a breathalyzer reading and actual impairment from THC.

Arguing Against the Results of a Blood Test

Blood tests are considered to be the most accurate way to measure THC levels in the body. However, there are still several factors that can affect the results, such as the way the blood sample was collected, stored, and tested. If the results of your blood test are questionable, you may be able to argue against them in court.

If your attorney can demonstrate that there were errors in the blood testing process or that the lab’s procedures were not followed correctly, it can cast doubt on the reliability of the evidence. The timing of the test is also crucial; because THC levels drop rapidly after consumption, a blood test taken hours after driving may not accurately reflect your level of impairment behind the wheel.

Proving You Were Not Impaired While Driving

One of the most effective legal defenses for a marijuana DUI charge is to prove that you were not actually impaired while driving. This can be done by presenting evidence that you were not exhibiting any signs of impairment while driving or by providing testimony from witnesses who were with you before or during the time of the arrest.

Additionally, you might highlight your consistent driving behavior or lack of accidents and infractions to support the claim that you were in full control of your vehicle. Surveillance footage from nearby businesses or traffic cameras can be invaluable in showing that your driving was unaffected by marijuana use.

Challenging the Validity of Drug Recognition Experts (DREs)

Drug Recognition Experts (DREs) are specially trained police officers who are supposed to be able to determine if a driver is impaired by drugs. However, these experts are not always reliable and their opinions may be biased. If you can prove that the DRE who evaluated you was not properly trained or that their testimony was biased, it can weaken the prosecution’s case against you.

The DRE protocol involves a series of tests that are subjective in nature and can be influenced by the officer’s preconceived notions. A defense attorney skilled in DUI cases will scrutinize the DRE’s report and the training they have received, often calling into question the scientific validity of their conclusions.

What to Do if You’re Facing a Marijuana DUI Charge

If you have been charged with a marijuana DUI in California, it’s important to seek legal representation as soon as possible. A skilled attorney can help you understand your rights, evaluate the evidence against you, and determine the best legal defense strategy for your case.

Additionally, if you believe that your rights were violated during the traffic stop or arrest, your attorney can help you file a motion to suppress evidence or challenge the validity of the charges. They can also negotiate with prosecutors to potentially reduce the charges or penalties you are facing.

Having a knowledgeable legal advocate on your side can make a significant difference in the outcome of your case. They can advise you on the steps to take following your arrest, such as refraining from discussing the case with anyone but your lawyer and documenting any evidence that may support your defense.


While being arrested for a marijuana DUI in California can be a stressful and overwhelming experience, there are several legal defense strategies that can help you fight the charge. By challenging the validity of the traffic stop, field sobriety tests, breathalyzer tests, blood tests, and drug recognition experts, you may be able to weaken the prosecution’s case against you and potentially avoid serious consequences.

If you are facing a marijuana DUI charge in California, it’s important to seek legal representation as soon as possible. A skilled attorney can help you navigate the complex legal system and fight for your rights. Remember, you are innocent until proven guilty, and with the right legal defense strategy, you may be able to avoid a conviction and move on with your life.
