The Plain Smell Doctrine in Florida Is Falling Apart — And It’s About Time
Most of my drug cases start with a vehicle search. And most of those vehicle searches start with a cop claiming they smelled weed. That single sentence has been justification enough under Florida law for decades to search every occupant in the car, open the trunk, go through purses and wallets, and root through everything looking for illegal drugs. We called it the plain smell doctrine.
Those days are ending. Not because I want them to, and not because defense attorneys complained loudly enough. They’re ending because of chemistry. Hemp and marijuana are the same plant, and seven billion people with noses cannot tell the difference between a legal substance and an illegal one — and neither can a trained drug dog.
Car Searched Because Police Claimed to Smell Weed?
That justification is legally weaker than it has ever been in Florida. Call John Guidry at (407) 423-1117 to find out if the plain smell doctrine still holds in your case.
What the Plain Smell Doctrine Actually Is
Under the automobile exception to the Fourth Amendment, police don’t need a warrant to search a vehicle when they have probable cause to believe it contains contraband. Florida courts have long held that an officer claiming to smell marijuana gives them exactly that probable cause — enough to search everything in the car, right there, right then.
This is a carve-out from the general warrant requirement. The logic was that cars are mobile, that drugs could disappear while an officer drives to a courthouse and back, and therefore the odor of marijuana serves as evidence of an ongoing crime. That logic made sense when all cannabis was illegal. It doesn’t anymore.
What Hemp Did to the Doctrine
In July 2019, Florida enacted the State Hemp Program under Florida Statute § 581.217. Hemp became completely legal. The problem is that hemp and marijuana are the same cannabis plant. They differ only in their THC content, which requires laboratory equipment to measure. No officer, no drug dog, and no human being on this planet can distinguish between legal hemp and illegal marijuana by smell. The arresting officer in Hatcher v. State, 342 So. 3d 807 (Fla. 1st DCA 2022), testified exactly that at the suppression hearing: burning hemp and burning marijuana smell identical.
That’s the problem with the plain smell doctrine in a post-hemp world. The moment you smell cannabis, you cannot know whether you’re smelling something legal or something illegal. Consequently, the smell tells you nothing about whether a crime is actually occurring.
Hatcher v. State: The First Crack
In Hatcher v. State, a sergeant stopped a van for erratic driving. The driver admitted he had just smoked a blunt and threw it out the window. The officer searched the van and found MDMA. On appeal, Hatcher argued that because hemp is indistinguishable from marijuana by smell, the odor alone couldn’t establish probable cause. The 1st DCA majority upheld the search on other grounds — Hatcher’s own admission removed any hemp defense he might have had. However, Judge Bilbrey wrote separately in a concurring opinion and said what many defense attorneys had been arguing for years: the plain smell doctrine, in a world where hemp is legal and indistinguishable from marijuana, can no longer stand. He called on the 1st DCA to recede from its prior holdings in an appropriate case. That opinion put the issue squarely on the table.
Baxter v. State: The Dam Breaks
The case that changed things in our home district is Baxter v. State, 389 So. 3d 803 (Fla. 5th DCA 2024). The 5th DCA decided it en banc — meaning the full court weighed in — and ruled that cannabis odor alone no longer establishes probable cause for a vehicle search in Florida. The reasoning tracks exactly what John and other defense attorneys have argued for years. The state bears the burden of proving that its warrantless search falls within a recognized exception to the Fourth Amendment. With hemp now legal, the state cannot prove that the odor of cannabis is necessarily evidence of criminal activity. Therefore, unless the state demonstrates something more than smell, the exception no longer applies.
Furthermore, the 2nd DCA reached the same conclusion en banc in October 2025 in Williams v. State. The doctrine is falling across Florida’s appellate courts, one district at a time.
What It Means Right Now for People Charged After a Smell Search
The law across Florida is still in transition. The 5th DCA, our home district covering Orange, Osceola, Seminole, Lake, Brevard, and Volusia counties, has ruled that odor alone doesn’t support a search. The 4th DCA still follows the old rule. The 1st and 3rd DCAs have acknowledged the issue without formally resolving it. The Florida Supreme Court has not yet weighed in to unify the standard statewide.
For anyone whose case started with a police officer claiming to smell cannabis from a vehicle, the question now is what district they’re in, whether there were additional factors cited beyond the smell, and whether the right attorney filed the right motion at the right time. Additionally, whether you said anything about hemp or a medical marijuana card during the stop matters enormously — Hatcher’s admission cost him the defense he would otherwise have had.

John’s Takeaways
- The plain smell doctrine held that cannabis odor alone gave police probable cause to search a vehicle without a warrant under the automobile exception to the Fourth Amendment.
- Hemp legalization ended the logical foundation of that rule. Hemp and marijuana smell identical. An officer smelling cannabis has no way to know whether they’re smelling something legal or illegal.
- In Hatcher v. State, 342 So. 3d 807 (Fla. 1st DCA 2022), Judge Bilbrey’s concurrence argued the doctrine can no longer survive hemp legalization — the first major crack in the armor from Florida’s own courts.
- In Baxter v. State, 389 So. 3d 803 (Fla. 5th DCA 2024), the full 5th DCA ruled en banc that cannabis odor alone no longer establishes probable cause. This applies directly to Central Florida.
- The Florida Supreme Court has not yet unified the rule statewide. What district your case is in, and what additional factors officers cited beyond the smell, determine how strong your suppression argument is right now.
Car Searched Based on Smell? Let’s Look at Whether the Doctrine Still Applies.
I’ve been challenging smell-based vehicle searches in Central Florida since before hemp was even a conversation, and Baxter changed everything for clients in this district. I represent clients across Orange, Seminole, Osceola, Lake, Brevard, and Volusia County.
If your case started with a claimed odor of cannabis, give my office a call. Let’s find out whether Baxter and the current state of the law give us a real argument to suppress everything the officers found.
