🌿 What Is a Weed DUI in Florida? Does DUI Always Mean Alcohol?
Most people think of alcohol when they hear “DUI”—but in Florida, driving under the influence of marijuana (a “weed DUI”) can carry the same penalties as alcohol-related offenses.
If you were stopped in Fort Lauderdale or South Florida, and the officer suspects cannabis impairment, you could be charged with DUI—even if your breath test is clean.
🚨 What Is a Marijuana (Weed) DUI?
A marijuana DUI occurs when a driver is suspected of being impaired by cannabis (THC) while operating a vehicle.
But here’s the challenge: unlike alcohol, there is no defined “legal limit” for marijuana impairment in Florida, and testing for it is scientifically unreliable.

🔬 Understanding Cannabis Metabolites: What Tests Really Show
If you consume cannabis, your body produces metabolites—substances detectable in your urine, blood, or saliva for up to 30 days. However:
- ✅ Metabolites do not prove you were impaired at the time of driving
- ✅ They may show up long after effects have worn off
- ✅ Florida often uses urine tests, which only detect inactive THC metabolites
📊 CDC Fact: Marijuana can impair driving—but testing for metabolites alone can’t confirm real-time impairment. That’s why toxicologists and defense attorneys frequently challenge these results.
⚖️ How Is Weed DUI Prosecuted in Florida?
DUI laws under Florida Statute § 316.193 apply to any substance that impairs your normal faculties—not just alcohol.
Common prosecution tools:
- 🚔 Officer observations (bloodshot eyes, odor of cannabis, speech)
- 🧪 Urine test showing cannabis metabolites
- 👣 Field Sobriety Exercises (FSEs) and body camera footage
- 📋 Statements made during the stop

Effective defense strategies include:
- Challenging the validity of the traffic stop
- Disputing the scientific value of urine test results
