Florida police could once search a vehicle on the basis of smelling marijuana. However, that rule is eroding.
State and federal laws now allow some forms of cannabis, and two Florida appellate courts have decided that odor alone no longer justifies a search. An experienced criminal defense attorney can describe the limits of the law if you are charged with drug possession during a traffic stop.
The Automobile Exception
The Fourth Amendment generally requires police to obtain a warrant before a search, but vehicles are an exception. The U.S. Supreme Court decided in 1925 that officers may search a car without a warrant if they have probable cause to believe it contains contraband, because a vehicle can be driven away before a warrant is issued. The central question is whether probable cause exists.
The “Plain Smell Rule”
Florida courts have traditionally treated the odor of marijuana like drugs sitting in plain view: if an officer smelled it, probable cause existed. As recently as 2021, in Owens v. State, the Second District Court of Appeal held that the smell of cannabis justified a vehicle search, even after medical marijuana and hemp became legal.
Why Hemp and Medical Marijuana Changed the Analysis
Florida allows qualified patients to buy medical marijuana from licensed treatment centers, and both state and federal law permit hemp containing no more than 0.3 percent THC. The problem is a legal supply cannot be distinguished from an illegal purchase by scent alone.
Two Courts Abandon Plain Smell
The Fifth District Court of Appeal ruled in Baxter v. State (2024) that because cannabis can now be lawfully possessed in several forms, its scent alone does not give police grounds to hold a driver for questioning.
In October 2025, the full Second District went further in Williams v. State. It overruled its own Owens decision and held that odor alone does not establish probable cause, directing courts to weigh the totality of the circumstances instead. It also asked the Florida Supreme Court to settle the issue statewide. Notably, Williams himself did not benefit, because the officers had relied in good faith on the law in effect at the time of his stop.
“Odor Plus”: When Police Can Still Search
Odor still matters when combined with other evidence. In State v. Fortin, an officer smelled fresh marijuana, saw a clear plastic bag of what appeared to be marijuana on the console, and spotted loose flakes in the car. The court found probable cause. It also noted that Florida law requires medical marijuana to stay in its original dispensary packaging, so cannabis in a plain baggie can raise suspicion even if the driver holds a medical card.
Other factors that may support a search include signs of impairment, admissions to the officer, contraband in plain view, or the driver’s consent.
Where You Are Stopped Still Matters
Florida’s six district courts of appeal have not all treated the issue alike, so until the Florida Supreme Court rules, your location may affect which standard applies.
Practical Tips for Residents and Visitors
- Recreational marijuana remains illegal in Florida, even if it is legal where you live. Possessing 20 grams or less is a first-degree misdemeanor.
- Florida does not honor out-of-state medical marijuana cards.
- Medical patients should keep cannabis in its original packaging and carry their state registry card.
- You may politely decline consent to search. Do not physically resist, even if you believe the search is unlawful.
- You may remain silent beyond providing your license, registration, and proof of insurance.
- The odor of cannabis may still factor into a DUI investigation.
