Can Police Search a Car for the Smell of Weed in Maryland? Not Solely

In Maryland the odor answer comes from a statute, not a court. The General Assembly wrote it in 2023, and it included the one line officers most need to know: a consent search doesn’t fix it.

Not on odor alone. Under Md. Code, Crim. Proc. § 1-211(a), an officer may not initiate a stop or a search of a person, a motor vehicle or a vessel based solely on the odor of burnt or unburnt cannabis. Evidence obtained in violation is inadmissible — “including evidence discovered or obtained with consent” (§ 1-211(c)).

Maryland: odor and the car — Odor can't start a stop or a search. Evidence found in violation is out, consent or not. — Maryland: odor and the car — the statute, the controlling cases, and what still gets you into the car. The full breakdown lives inside StreetSense, offline.

What § 1-211 says

An officer “may not initiate a stop or a search” based solely on one or more of: (1) the odor of burnt or unburnt cannabis; (2) possession or suspected possession of no more than the personal use amount; or (3) cash near cannabis “without other indicia of an intent to distribute.”
It covers persons, motor vehicles and vessels, effective July 1, 2023.
(c) is the teeth: evidence obtained in violation “is not admissible in a trial, a hearing, or any other proceeding” — consent included. The statute contains no good-faith exception on its face.
Cutchember v. State, 493 Md. 187 (2026) (Supreme Court of Maryland, unanimous): “as of July 1, 2023 … law enforcement may no longer rely on the odor of cannabis alone to justify a stop or search.” The statute superseded the Court’s earlier odor holdings (Robinson and In re D.D.), but it does not reach searches made before July 1, 2023, whenever the suppression hearing is held.

“Solely” — the under-21 ruling

Sudler v. State / Trotter v. State (Appellate Court of Maryland, reported, July 30, 2026): odor plus the officer’s knowledge that the occupants were under 21 was not “solely” odor, because it is unlawful for a person under 21 to possess cannabis. The statute did not bar that search or require exclusion.
Read it narrowly: a statutory ruling only. The Fourth Amendment wasn’t argued, so the court did not decide whether odor plus under-21 is probable cause. It is two months old; check whether further review has been sought before you lean on it.

The person is different: Lewis and Pacheco

Lewis v. State, 470 Md. 1 (2020): “the mere odor of marijuana emanating from a person, without more, does not provide the police with probable cause to support an arrest and a full-scale search of the arrestee.”
Pacheco v. State, 465 Md. 311 (2019): a joint and the odor of burnt marijuana gave no probable cause that he had a criminal amount, so his arrest and search were unreasonable.
Both are Fourth Amendment cases from the era when small amounts were a civil offense. Neither has been overruled.
Where you smell it from matters. Grant v. State, 449 Md. 1 (2016): the trial court erred in denying suppression where it couldn’t be determined whether the deputy smelled marijuana before or after he put his head through the passenger window. The Court noted that courts generally treat an officer’s physical intrusion through an open window as a search.

Impaired driving narrows the search

There is no DUI carve-out from the odor bar. The only DUI rule cuts the other way.
§ 1-211(b): if you are investigating a driver solely for driving impaired by or under the influence of cannabis, you may not search any area of the vehicle that is not readily accessible to the driver or reasonably likely to contain evidence of the driver’s condition.

How much is legal, and in the car

Adults 21 and over may possess the personal use amount: 1.5 ounces of usable cannabis, 12 grams of concentrate, or products with 750 mg of THC (CR § 5-101(u)).
More than 1.5 up to 2.5 ounces (the civil use amount) is a civil offense, fine up to $250. More than that is a misdemeanor: up to 6 months and/or $1,000. Under 21 with the personal use amount: civil, up to $100 (CR § 5-601).
Driver smoking or consuming cannabis in the passenger area on a highway: TR § 21-903(c), a Vehicle Law misdemeanor, fine up to $500. Passenger smoking cannabis in the passenger area: CR § 10-125(b)(3), a civil offense, $25.
Maryland has no cannabis open-container offense; § 10-125(a) is alcohol only.

The federal floor — and why it doesn't decide your case

Under the Fourth Amendment the automobile exception needs probable cause and nothing more (Maryland v. Dyson, 527 U.S. 465 (1999)), and marijuana is still illegal under federal law.
Maryland’s rule comes from its statute, which gives more protection than that floor.
That is the floor. A state court applying its own statute or constitution can — and here does — suppress what a federal court would admit. Work to your state’s rule.

How it plays out on the street

Night stop for a dead headlight. Strong smell of burnt cannabis, one adult driver, nothing in view. You have no search, and asking for consent doesn’t help — § 1-211(c) throws out consent evidence too. If the driving and your observations point to impairment, investigate impairment; if cannabis DUI is the only thing you’re investigating, search only what the driver could reach or what’s likely to hold evidence of the driver’s condition. Keep your head outside the window. Write the headlight and move on.

Frequently asked questions

Can police search your car for the smell of weed in Maryland?

Not based solely on odor. Since July 1, 2023, Md. Code, Crim.

No. § 1-211(c) says evidence discovered or obtained in violation of the section, including evidence discovered or obtained with consent, is not admissible in a trial, hearing or any other proceeding.

How much weed can you have in your car in Maryland?

Adults 21 and over may possess up to 1.5 ounces of usable cannabis. More than 1.5 and up to 2.5 ounces is a civil offense; more than that is a misdemeanor.
