For years, the smell of marijuana was enough for Florida police to stop, detain, search, and even arrest someone. But after hemp legalization in 2019, courts across Florida have begun holding that odor alone does NOT automatically create probable cause to search or arrest.
Because hemp and marijuana smell exactly the same, officers can no longer assume the odor means illegal activity. Still, many officers — especially in Broward and Miami-Dade — continue to rely on smell as the justification for traffic stops, detentions, or vehicle searches.
Here’s what the law actually says.
⚖️ Can Police Arrest You Solely Based on the Smell of Marijuana?
Short answer: Not usually.
The smell of cannabis may be a factor in determining probable cause, but Florida courts increasingly reject odor as the sole basis for:
Arrest
Detention
Vehicle searches
Backpack searches
Pat-downs
Prolonged traffic stops
To justify an arrest, police must point to additional indicators of criminal activity.
This is the same layered-probable-cause analysis we challenge in our posts on marijuana smell detentions, car searches after DUI arrests, and motion to suppress strategies.
🚫 When Odor Alone Is NOT Enough for Arrest
Odor by itself does not justify arrest when:
There is no evidence of impairment
There is no visible cannabis
There are no admissions
The odor is faint, ambiguous, or environmental
The odor comes from someone else in the vehicle
The odor is consistent with legal hemp or CBD products
Officers use odor to extend a traffic stop without cause
Courts have repeatedly held that smell must be combined with independent suspicious facts to establish probable cause.
This is directly in line with your post on whether police can detain you for smell alone.
🚓 When Odor Can Contribute to Probable Cause
Smell may support arrest when combined with other evidence, such as:
Marijuana visible in the vehicle
Smoke coming from the car
Impaired driving pattern
Admissions of recent use
Contraband in plain view
K-9 alert (though K-9 reliability is frequently challenged)
Paraphernalia found during lawful detention
Still, odor must be part of a totality of the circumstances analysis.
🚗 What About Arrests After Traffic Stops?
During traffic stops, officers frequently say:
“I smell burnt marijuana.”
But smell does not automatically allow:
A full vehicle search
Ordering all passengers out
Arresting passengers
Running passenger IDs
Extending the duration of the stop
These issues often appear alongside unlawful extensions similar to passenger name-check cases and ID-demand cases, both of which you’ve already covered.

🧪 What About Hemp?
Hemp is legal in Florida.
THC-free hemp products smell identical to marijuana.
Because officers cannot distinguish legal hemp from illegal cannabis by smell, odor-only arrests often violate:
Fourth Amendment probable cause standards
Florida Constitution privacy protections
Recent Florida appellate decisions
Hemp legislation passed in 2019
This is a powerful defense in suppression hearings.
🛡️ Defenses to Odor-Based Arrests
At Michael White, P.A., common defenses include:
✔ Odor-only detention was unlawful
If the stop or arrest was based solely on smell, we file a motion to suppress.
✔ Hemp defense
Odor cannot distinguish lawful hemp from illegal marijuana.
✔ Environmental odor
Odor may have come from the environment, adjacent vehicles, or other occupants.
✔ Lack of corroborating evidence
No admissions, no impairment, no contraband = no probable cause.
✔ Bad K-9 alert
K-9 reliability is frequently litigated, especially after long delays or improper deployments.
✔ Inconsistent officer statements
Bodycam often contradicts the officer’s description of odor strength or source.
