Can Police Search Your Car for the Smell of Marijuana in Florida? In Federal Court, the Answer Is Still Yes

You were stopped on I-95 in Palm Beach County. The officer leaned toward the window, said he smelled marijuana, and searched the car. He found a handgun. Whether that search survives may depend less on what was in the car than on which courthouse the case lands in. Florida appellate courts have been pulling away from the rule that odor alone justifies a search. On October 29, 2026, the Eleventh Circuit made clear that federal court has not moved at all.

The same stop can win suppression in state court and lose it in federal court.

Key Takeaways

• The Eleventh Circuit still treats the smell of marijuana alone as probable cause to search a car, and repeated that position on October 29, 2026.
• Florida's Second and Fifth District Courts of Appeal hold odor alone is not enough, because hemp is legal under Fla. Stat. 581.217.
• A Florida stop that turns up a gun or drugs can become a federal case under 18 U.S.C. 922(g) or 21 U.S.C. 841.
• Raise the odor argument expressly in the pretrial motion under Fed. R. Crim. P. 12(b)(3), or it gets only plain-error review.
• Southern and Middle District of Florida defendants should preserve the issue now, because federal hemp law under Pub. L. 119-37 is changing this year.

What the Eleventh Circuit Decided on October 29

The case came out of the Middle District of Florida. Officers searched a car after testifying that they smelled marijuana, found a firearm, and the occupant was convicted of possessing it as a felon under 18 U.S.C. 922(g)(1). Below, the defense argued only that the officers were not credible; the judge disagreed and denied suppression.

On appeal, the defense made a better argument: after Florida legalized hemp and medical marijuana, the odor of marijuana alone can no longer establish probable cause under the automobile exception. The panel refused to treat that as a variation on the credibility argument. It called it a different issue, reviewed it only for plain error under Fed. R. Crim. P. 52(b), and found none.

An unpublished opinion does not bind later panels. It does tell you where the court stands, and at least one other recent unpublished decision, No. 25-11854, applied the same 2024 footnote to a car search. Until the Eleventh Circuit sits en banc or the Supreme Court speaks, odor alone is probable cause in every federal courtroom in Florida.

Florida Courts Have Moved; Federal Court Has Not

State law is a different story. In 2024 the Fifth District, sitting en banc, held that the plain smell of cannabis no longer supplies even reasonable suspicion for a detention, 389 So. 3d 803 (Fla. 5th DCA 2024). The court relied on the statutory definitions: cannabis under Fla. Stat. 893.02(3), hemp under Fla. Stat. 581.217, and medical marijuana under Fla. Stat. 381.986. If lawful and unlawful cannabis smell the same, odor alone does not make contraband apparent.

On October 1, 2025, the Second District followed, also en banc, in No. 2D2023-2200: "the smell of cannabis standing alone is insufficient to establish probable cause." It certified the question to the Florida Supreme Court. The defendant still lost; the evidence came in under the good-faith exception.

"The smell of cannabis standing alone is insufficient to establish probable cause."— Florida Second District Court of Appeal, en banc, No. 2D2023-2200 (October 1, 2025)

The Fourth District, which covers Palm Beach and Broward counties, has older precedent treating odor alone as probable cause, 143 So. 3d 1050 (Fla. 4th DCA 2014). In a 2024 decision, 383 So. 3d 820, it acknowledged that the rule has "come under scrutiny" but decided the case on marijuana in plain view and left the question open. The Legislature tried to write plain smell into the statutes in 2026; SB 1056 died in committee on March 13, 2026.

The reason federal court sees it differently is structural. The Fourth Amendment is federal law, and a federal judge in Tampa or West Palm Beach follows the Eleventh Circuit, not the Second or Fifth District. The same stop can win suppression in state court and lose it in federal court.

How a Florida Traffic Stop Becomes a Federal Case

Task force officers make many of these stops, and the U.S. Attorney's Office can adopt the case before a state judge hears a motion. A firearm found on someone with a prior felony becomes a 922(g)(1) charge carrying up to 15 years under 18 U.S.C. 924(a)(8), or a 15-year mandatory minimum under the Armed Career Criminal Act, 18 U.S.C. 924(e). Drugs in the same car bring 21 U.S.C. 841. A gun near the drugs can add a five-year consecutive mandatory minimum under 18 U.S.C. 924(c).

Task force officers make many of these stops, and the U.S. Attorney's Office can adopt the case before a state judge hears a motion.

When the only basis for a search is odor, federal suppression law favors the government. A 21 U.S.C. 841 defense or a 922(g) defense that would win a motion in a state courtroom may lose the same motion in the federal courthouse down the street. That is a reason to involve a federal drug conspiracy attorney the moment a state case starts to look federal.

Critical Mistakes People Make in Odor Cases

The first mistake happens at the roadside. Odor plus something else can still supply probable cause in every Florida district, and the something else is usually supplied by the driver. "I smoked earlier" or "my friend had a joint" ends the argument. So does consenting to the search.

The second mistake is the one the October 29 decision punished: filing a motion that attacks only the officer's credibility. If the theory is that odor cannot establish probable cause because hemp and medical marijuana are legal, the motion has to say so, in those terms, under Fed. R. Crim. P. 12(b)(3). An alternative argument raised for the first time on appeal gets plain-error review, and against binding precedent plain error is nearly impossible to show.

The fourth mistake is waiting. After indictment, the motion deadline can come quickly. Anyone under federal investigation after a stop, including anyone looking for a Middle District of Florida defense attorney or Southern District of Florida federal defense counsel, or anyone who has received a target letter or a grand jury subpoena, should speak with a federal indictment lawyer before that clock starts.

Strategic Defense: Preserve the Issue for the Case and the Appeal

The federal hemp definition is about to change. Section 781 of Pub. L. 119-37 replaces the delta-9 THC test in 7 U.S.C. 1639o with a total-THC standard and excludes most intoxicating hemp products; the Congressional Research Service summarizes the new definition. The ban on synthetic cannabinoids takes effect November 12, 2026, and the total-THC standard is now scheduled for December 11, 2026. Prosecutors will argue that a narrower definition of legal hemp restores the inference that odor means contraband. The defense answer is that Florida medical marijuana remains lawful and smells the same. This is messier than either side will admit.

If agents are already involved, a federal search warrant attorney can address any phone or home search that followed the stop and position the case for sentencing if suppression fails.

Why Timing Matters

Federal hemp law changes this fall. The Florida Supreme Court has a certified question in front of it. The Eleventh Circuit has applied its odor rule in at least two recent unpublished decisions and has said that only the full court or the Supreme Court can change it. Only a preserved argument benefits if any of them moves. Defendants charged in the Southern District of Florida or the Middle District of Florida after an odor-based search should treat the motion to suppress as an appellate document from the day it is filed.
