Key Findings on Prescription DUID Charges
If you’re facing a DUID (Driving Under the Influence of Drugs) charge in Colorado involving medication prescribed by your doctor, you are likely feeling shocked, confused, and unfairly targeted. It’s a situation that can turn your life upside down. Here is what you need to understand right away:
• A Valid Prescription is Not a Defense: In Colorado, having a legal prescription for a drug like an opioid, benzodiazepine, or stimulant is not a defense if the state believes it impaired your ability to drive safely.
• No ‘Per Se’ Limit Exists: Unlike alcohol, which has a 0.08% BAC legal limit, there is no set numerical limit for most prescription drugs that automatically proves impairment.
• The Case Hinges on Opinion: Because there’s no per se limit, the prosecution’s entire case often rests on the subjective opinion and observations of a single law enforcement officer, a Drug Recognition Expert (DRE).
• DRE Testimony is Challengeable: DRE evaluations are a process, but they are subject to human error, misinterpretation of medical conditions, and procedural mistakes. This means the DRE testimony is a critical area to challenge in your defense.
Introduction: The Shock of a Prescription DUID Arrest
You did everything right. You saw a doctor, received a diagnosis, and took your medication exactly as prescribed. Yet, you found yourself on the side of the road, undergoing tests, and ultimately being arrested for DUID. This scenario is frighteningly common in Colorado. The feeling of being treated like a criminal for following medical advice is overwhelming, and the stakes, loss of your license, your job, and your freedom, are incredibly high.
This post is designed to answer a critical question: How can the state charge you with DUID when you were taking legal, prescribed medication? The answer lies in the state’s reliance on the Drug Recognition Expert (DRE) evaluation. As former prosecutors, we at Right Law Group have seen firsthand how these cases are built from the inside. We understand the procedures, the science, and most importantly, the vulnerabilities in the prosecution’s case. Understanding the DRE process is the first step toward building a strong defense and protecting your future.
Deep-Dive: Dissecting the DRE Evaluation
A DRE is a law enforcement officer with additional training who is called in to determine if a driver is under the influence of drugs. They follow a standardized process to form an opinion. While it sounds scientific, nearly every step has a subjective component that a knowledgeable defense attorney can scrutinize.
Here’s a breakdown of the process and where it can go wrong:
• Breath Alcohol Test: The DRE first confirms that alcohol is not the source of the impairment. If you blow a 0.00, they proceed with the drug evaluation.
• Interview of the Arresting Officer: The DRE is told what to look for before even meeting you. This can create a confirmation bias from the very beginning.
• Preliminary Examination: The DRE asks initial questions. Nerves, anxiety, or a pre-existing medical condition can easily be misinterpreted as signs of drug impairment.
• Eye Examination: The officer looks for Horizontal Gaze Nystagmus (HGN), Vertical Gaze Nystagmus (VGN), and Lack of Convergence. These tests are highly technical, and improper administration can produce false positives. Many medical conditions can also cause nystagmus.
• Divided Attention Tests: These are the classic field sobriety tests (Walk and Turn, One Leg Stand). Physical injuries, age, weight, and inner-ear problems can affect performance, yet officers may attribute any misstep to impairment,
• Interview and Statements: If you are read your Miranda rights, the DRE may interrogate you about your drug use. Anything you say can be used to confirm the DRE’s developing opinion.
• The DRE’s Opinion: Based on the totality of these steps, the DRE forms an opinion about which category of drug they believe is causing impairment. This is an educated guess, not a medical diagnosis.
• Toxicological Sample: The DRE requests a blood or urine sample. Crucially, the simple presence of a prescribed drug in your system does not prove you were impaired by it at the time of driving.
Technical Case Study: When Anxiety Looks Like Impairment
Consider a realistic scenario: A client with a prescription for a benzodiazepine to treat a diagnosed anxiety disorder is pulled over for weaving within their lane. The flashing lights and police interaction trigger a panic attack. The arresting officer observes the client’s shaking hands, rapid speech, and nervousness, and suspects drug impairment.
A DRE is called to the investigation. During the evaluation, the client’s pulse and blood pressure are elevated due to their anxiety. They struggle with the one-leg stand test because they are flustered and distracted. The DRE, biased by the initial report of “weaving,” concludes the client is impaired by a CNS Depressant. A subsequent blood test confirms the presence of the prescribed medication.
The defense strategy here is not to deny the client was taking their medication. Instead, the strategy is to show that the signs the DRE interpreted as “impairment” were, in fact, symptoms of the very medical condition the drug was prescribed to treat. By presenting medical records and sometimes testimony from the client’s doctor, we can provide an alternative, innocent explanation for the DRE’s observations. This creates reasonable doubt and pursues the best possible outcome for the client, which could be a dismissal or a favorable plea to a lesser charge.
Frequently Asked Questions About Prescription DUIDs
Can I get a DUID for taking my prescribed Adderall or Ritalin?
Yes. While stimulants like Adderall are legally prescribed, the prosecution can argue they impaired your ability to drive safely, for example, by causing agitation, recklessness, or overconfidence. The DRE’s opinion will be central to this claim.
What if I told the officer I was on medication?
Admitting you are on medication is often used by the DRE to confirm their suspicions. While you should not lie to law enforcement, it is crucial to remember you have the right to remain silent. Any admission can and will be used to build the case against you.
How can a lawyer fight a DRE officer’s testimony?
A defense attorney can challenge a DRE’s conclusions by scrutinizing their training records, looking for procedural errors in the evaluation, presenting evidence of medical conditions that mimic impairment, and cross-examining the officer in court to expose the subjective nature of their opinion.
Do I have to take the DRE tests?
The physical tests, like the walk-and-turn or one-leg stand, are voluntary. However, under Colorado’s Express Consent law, refusing a chemical test (blood or breath) carries its own serious administrative penalties, including a lengthy driver’s license revocation.
How long does a prescription DUID case take to resolve in Colorado?
The timeline can vary widely from a few months to over a year. Factors include the complexity of the case, the court’s schedule, and whether the case is resolved through negotiation or proceeds to a trial.
Conclusion: Take the Next Step to Secure Your Defense
A DUID charge involving prescribed medication is not a conviction. The prosecution’s case is built on a foundation of subjective observations and opinions that can be effectively challenged. You are not automatically guilty just because you were taking medication and driving. The key is to demonstrate that the state cannot prove, beyond a reasonable doubt, that you were actually impaired.
Navigating the complexities of DRE testimony and Colorado DUI law requires a defense team with deep knowledge of how these cases are prosecuted. If you are facing this frightening situation, the most important thing you can do is understand your rights and options.
