Most people picture a breathalyzer when they think of a DUI. A drug DUI works differently, and that difference can leave you facing a criminal charge with no simple number to point to. If you were arrested in Tampa for driving under the influence of drugs, whether an illegal substance or a medication your doctor prescribed, a Tampa drug DUI lawyer at Metcalf Falls, Criminal Defense Attorneys, P.A. can help you understand what the state actually has to prove. Attorney Brett Metcalf is a former Hillsborough County prosecutor who knows how these cases are built, and how they come apart.

What is a Drug DUI in Florida?
Florida’s DUI law is not limited to alcohol. The same statute makes it a crime to drive or be in actual physical control of a vehicle while your normal faculties are impaired by any chemical or controlled substance. That includes illegal drugs, but it also affects lawful prescription medication and even over-the-counter drugs if the state claims they affect your ability to drive.
Is There a “Legal Limit” for Drugs in a DUI?
Drug-related DUIs are different from alcohol-related charges. For alcohol, Florida has a clear line at a .08 breath or blood level. For drugs, there is no equivalent per se limit. The question is not how much of a substance was in your system but whether it impaired your “normal faculties,” meaning things like your judgment, coordination, and reaction time.
Because that standard is subjective, a drug DUI often turns on interpretation, and interpretation can be challenged.
Penalties for a Drug DUI in Florida
A drug DUI is punished the same way as an alcohol DUI under Fla. Stat. 316.193, so the penalties escalate with each offense.
- First conviction carries a fine of $500 to $1,000, up to six months in jail, and a driver license revocation of 180 days to one year.
- Second offenses within five years of a prior brings a mandatory minimum of 10 days in jail and a required ignition interlock device.
- Third drug DUIs within 10 years are third-degree felonies, with a mandatory 30 days in jail and up to five years in prison.
Certain drug DUIs can also become felonies when someone is seriously hurt. Beyond the sentence, a drug DUI conviction can affect your license, your job, and any professional certification you hold, which is why it is worth fighting from the start.
What Happens After a Drug DUI Arrest
Because there is no roadside test for drugs, these arrests follow a different process. Instead of a breath sample, officers usually request a blood or urine test. They can also bring in a Drug Recognition Expert, or DRE. A DRE is an officer trained to perform a 12-step evaluation and then testify that you were impaired by a specific category of drug.
Are There Issues with DRE Evaluations & Blood Tests?
A blood or urine test can show that a substance was present, but presence is not the same as impairment; many drugs linger in the body long after any effect has worn off. And a DRE evaluation, despite the “expert” label, is a subjective checklist performed by a police officer, not a lab result. Both are open to challenge.
What Do Blood Tests Show?
It helps to understand what these tests can and cannot show. A blood draw must be taken by qualified personnel and stored correctly, and a urine sample is an even blunter tool, because it can detect substances used days earlier that have nothing to do with how you were driving. We request the underlying records, the lab’s analysis, and any available video, since the details of collection and testing are often what determine whether a drug DUI case is won or lost.
How We Defend Drug DUI Charges
A drug DUI case has more moving parts than an alcohol case, and that can work in your favor. We take apart each piece of the state’s proof, from the reason for the stop to the science behind the testing.
We Challenge the Traffic Stop
If the officer did not have a lawful reason to pull you over or detain you, we can move to suppress everything that followed. A defective stop can unravel the entire case.
We Attack the DRE Evaluation
The 12-step drug evaluation depends on an officer’s subjective reading of your eyes, pulse, and behavior. Symptoms an officer blames on drugs can come from fatigue, anxiety, or a medical condition, and we press hard on that gap.
We Question the Blood or Urine Test
Samples have to be collected, stored, and analyzed under strict protocols. When the chain of custody, the timing, or the lab procedure falls short, we argue the result should carry little or no weight.
We Separate Drug Presence From Actual Impairment
The state must prove impairment, not just that a substance was in your body. We can use the science, and the witnesses, to show that a positive test does not prove you were actually impaired behind the wheel. Toxicology has limits, and a number on a report is not the same as proof that your driving was affected. We put that distinction squarely in front of the judge and jury.

Drug DUI FAQs
Can you get a DUI for prescription medication in Florida?
Yes. Fla. Stat. 316.193 covers impairment by any drug, including a medication your doctor prescribed, if the state claims it affected your normal faculties. A valid prescription is not an automatic defense, but it can be an important part of one.
How do they prove a drug DUI without a breathalyzer?
Through a combination of the officer’s observations, field sobriety exercises, a Drug Recognition Expert evaluation, and a blood or urine test. Each of those can be challenged.
Is there a legal limit for drugs like there is for alcohol?
No. Unlike the .08 standard for alcohol, Florida has no per se limit for drugs. The state must prove your normal faculties were impaired.
Can a drug DUI be a felony?
It can. A third drug DUI within 10 years, a fourth ever, or a drug DUI causing serious bodily injury can be charged as a felony.
What is a Drug Recognition Expert?
A DRE is a police officer trained to conduct a standardized 12-step evaluation and testify about suspected drug impairment. It is a subjective process, not a scientific test, and it can be questioned in court.
Does a drug in my system mean I was impaired?
Not necessarily. Many substances remain detectable long after any effect has passed, so a positive test alone does not prove you were impaired while driving.
Can I get a DUI for marijuana in Florida?
Yes. Driving while impaired by marijuana can support a DUI under Fla. Stat. 316.193, even when the marijuana was obtained legally through a medical program. As with any drug DUI, the state must prove impairment, not just use.
Is a prescription a defense to a drug DUI?
Having a valid prescription can be an important part of a strong defense, but it is not automatic. The state can still argue the medication impaired you, so how you took it and what the evidence shows about actual impairment make the difference.
What happens to my license after a drug DUI?
A drug DUI triggers the same license consequences as an alcohol DUI, including the administrative suspension you have 10 days to challenge. A conviction leads to a revocation period that grows longer with each offense.
