A Florida DUI Defense Attorney Explains How Medical Marijuana, Officer Observations, and Testing Issues Affect DUI Cases
Can Medical Marijuana DUI Charges Be Reduced in Florida, What You Need to Know Right Away
If you are facing a DUI charge in Florida involving medical marijuana, you are likely confused, frustrated, and worried about your future. Many of my clients are legally registered medical marijuana patients who never expected to be arrested for DUI. They followed the law, had a valid card, and did not believe they were impaired. Yet they still found themselves in handcuffs based on an officer’s interpretation of behavior rather than reliable scientific proof.
As a Florida DUI defense attorney, I can tell you that medical marijuana DUI charges can often be reduced, and in many cases dismissed, when the defense is handled correctly. These cases are very different from alcohol DUI cases. There is no clear legal THC limit in Florida. There is no reliable roadside test that proves impairment at the time of driving. Most medical marijuana DUI cases depend almost entirely on officer opinion, field sobriety exercises, and flawed drug recognition evaluations.
Florida law allows DUI charges based on impairment from controlled substances, including cannabis, even when the substance was legally obtained. However, the law still requires the state to prove that your normal faculties were impaired at the time you were driving. That burden is much harder for prosecutors to meet in medical marijuana cases, especially when a private attorney challenges the evidence early and thoroughly.
How Florida Law Treats DUI Allegations Involving Medical Marijuana
Florida DUI law defines impairment broadly. The statute summarizes that a person can be charged with DUI if their ability to drive safely is affected by alcohol, chemical substances, or controlled substances. Medical marijuana falls under this category. Importantly, the statute does not say that simply having THC in your system equals impairment. The state must show actual impairment at the time of driving.
Florida’s medical marijuana laws allow qualified patients to lawfully use cannabis products. However, these laws do not create immunity from DUI charges. What they do create is a legal gray area. THC can remain in the body long after any psychoactive effects have worn off. Blood or urine tests often detect THC days or even weeks after use. That scientific reality makes it very difficult for prosecutors to link test results to impairment at the time of driving.
Because of this gap, law enforcement often relies on subjective indicators such as:
- Alleged odor of cannabis
- Bloodshot eyes
- Slow responses
- Nervousness
- Performance on roadside exercises
- Statements made during questioning
These factors are not reliable indicators of impairment, especially for registered medical marijuana patients. A private attorney understands how to challenge these assumptions and show that legal use does not equal unsafe driving.
Why Medical Marijuana DUI Cases Are Fundamentally Different From Alcohol DUI Cases
Alcohol DUI cases rely heavily on breath or blood alcohol concentration. Florida law establishes clear numerical thresholds for alcohol impairment. Medical marijuana cases do not have that clarity. There is no per se THC limit in Florida. The absence of a defined standard makes marijuana DUI cases far more vulnerable to challenge.
THC affects individuals differently. A registered patient may have tolerance due to consistent medical use. Effects may be mild or nonexistent at the time of driving. Unlike alcohol, THC levels in the blood do not reliably correlate with impairment. Scientific studies have consistently shown that THC presence alone does not indicate driving impairment.
Because of this, prosecutors must lean on officer testimony. That reliance creates opportunity for a strong defense. I focus on exposing weaknesses in the officer’s observations, inconsistencies in reports, and alternative explanations for alleged symptoms. When those issues are presented clearly, reductions and dismissals become realistic outcomes.
How Officers Build Medical Marijuana DUI Cases
Most medical marijuana DUI arrests follow a predictable pattern. The stop often begins with a minor traffic infraction or checkpoint. The officer then claims to notice signs that suggest drug use. From there, the investigation escalates quickly.
Common steps include:
- Questions about medication or marijuana use
- Requests to perform roadside exercises
- Searches of the vehicle
- Requests for blood or urine samples
- Involvement of a drug recognition evaluator
Drug recognition evaluations are not scientific tests. They rely on subjective interpretation and checklists. Many officers conducting these evaluations lack proper training or fail to follow standardized procedures. Their conclusions are frequently overstated and can be challenged effectively.
A private attorney reviews body camera footage, evaluates the testing process, and determines whether the officer followed proper procedures. Errors in these steps often lead to reduced charges.
Can Medical Marijuana DUI Charges Be Reduced to Reckless Driving
Yes, medical marijuana DUI charges can often be reduced to reckless driving. Prosecutors consider reductions when they see weaknesses in their case. Common factors that support reductions include:
- No accident or injury
- Clean driving history
- Valid medical marijuana card
- Lack of reliable impairment evidence
- Inconsistent officer testimony
- Poorly administered roadside tests
- Negative or inconclusive toxicology results
Reckless driving carries far fewer consequences than DUI. It avoids mandatory DUI penalties, license suspension issues, and long-term stigma. My goal in many medical marijuana DUI cases is to position the case for this type of resolution.
Defenses That Apply to Medical Marijuana DUI Cases in Florida
Medical marijuana DUI cases offer multiple defense strategies. Some of the most effective include:
Lack of impairment
The state must prove your driving ability was impaired. The presence of THC alone is not enough.
Legal medical use
A valid medical marijuana card supports lawful use and challenges assumptions of illegal behavior.
Faulty roadside exercises
Roadside exercises are not designed to detect cannabis impairment and are often misinterpreted.
Improper drug recognition evaluation
Many evaluations fail to meet required standards and can be excluded or discredited.
Unlawful traffic stop
If the stop lacked legal justification, evidence obtained afterward may be suppressed.
Inaccurate toxicology testing
Blood and urine tests do not measure impairment and often reflect past use only.
Medical conditions
Symptoms attributed to impairment may be caused by anxiety, fatigue, chronic pain, or other conditions.
A private attorney knows how to connect these defenses into a cohesive argument that undermines the state’s case.
A Real Case Example From My Practice
I represented a client who was stopped late at night after leaving a medical appointment. The officer claimed the client appeared nervous and had red eyes. The client disclosed being a registered medical marijuana patient but denied being impaired. No accident occurred. No unsafe driving was documented.
The officer requested roadside exercises, which the client performed adequately. A drug recognition evaluator later claimed signs of cannabis influence. A urine test showed THC metabolites.
I obtained the client’s medical records, confirming chronic pain treatment. Body camera footage showed clear speech, steady balance, and appropriate responses. The evaluator failed to follow proper evaluation steps. I challenged the traffic stop, the evaluator’s conclusions, and the reliability of the urine test.
The prosecutor agreed the evidence did not support impairment beyond speculation. The DUI charge was dismissed entirely. The client avoided license issues, fines, and a criminal record.
Why You Need a Private Attorney for a Medical Marijuana DUI Charge
Medical marijuana DUI cases require more than basic representation. These cases involve science, procedure, and credibility. Public defenders are often overloaded and may not have time to scrutinize drug recognition evaluations or toxicology reports in detail.
A private attorney can:
- Secure body camera footage before deletion
- Review toxicology testing methods
- Challenge drug recognition evaluations
- Present medical documentation
- Identify constitutional violations
- Negotiate directly with prosecutors
- Push for charge reductions or dismissal
Early involvement increases leverage and improves outcomes.
Long Term Consequences of a Medical Marijuana DUI Conviction
A DUI conviction can affect:
- Your driver’s license
- Employment
- Professional licenses
- Background checks
- Insurance rates
- Immigration status
Even for medical marijuana patients, a DUI conviction carries lasting consequences. Reducing or dismissing the charge protects far more than just your driving record.
FAQs, Answered by a Florida DUI Defense Attorney
Can I be charged with DUI if I have a medical marijuana card?
Yes. Florida law allows DUI charges based on impairment from controlled substances, even when legally prescribed. However, having a valid card helps the defense by showing lawful use and challenging assumptions of illegal conduct. The state must still prove impairment at the time of driving.
Is there a legal THC limit in Florida like alcohol?
No. Florida does not have a numerical THC limit. This makes medical marijuana DUI cases more difficult for prosecutors. Without a clear standard, they must rely on officer opinion and subjective evidence, which can be challenged.
Can a blood or urine test prove I was impaired?
Not reliably. These tests show the presence of THC or metabolites but do not establish impairment at the time of driving. THC can remain in the body long after effects have faded. This is a key defense point.
What if the officer says I failed field sobriety tests?
Field sobriety exercises were developed for alcohol, not cannabis. Performance can be affected by medical conditions, anxiety, or fatigue. Video footage often contradicts officer claims. I analyze the footage carefully to challenge these assertions.
What is a drug recognition evaluator and can they be wrong?
A drug recognition evaluator is an officer trained to identify drug influence based on observations. Their conclusions are subjective and frequently flawed. Improper training or deviations from procedure weaken their testimony.
Can medical marijuana DUI charges be reduced?
Yes. Many cases are reduced to reckless driving or dismissed when evidence is weak. Reduction depends on the strength of the defense and early intervention.
Should I speak to police about my medical marijuana use?
Statements can be used against you. It is best to consult a lawyer before answering questions. I help clients understand how statements impact their case.
How soon should I hire a lawyer after a medical marijuana DUI arrest?
Immediately. Evidence preservation and license deadlines move fast. Early legal involvement often leads to better outcomes.
