Can Police Search a Car for the Smell of Weed in Alaska? Undecided — and Clark Still Wants Exigency

Alaska made an ounce legal for adults in February 2015. In the decade since, we found no published Alaska appellate decision on whether the smell of marijuana still gets you into a car. What the courts have said points one way: be ready to show more than the smell, and be ready to get a warrant.

Can Police Search a Car for the Smell of Weed in Alaska? Undecided — and Clark Still Wants Exigency

Not on odor alone, and no published Alaska appellate decision has settled it. Since Feb. 24, 2015, adults 21 and over may possess and transport one ounce or less (AS 17.38.020). Alaska’s Court of Appeals has held, in home-warrant cases, that when some possession is lawful, odor shows marijuana is present but not that a crime is happening (State v. Crocker, 97 P.3d 93 (Alaska App. 2004)). And even with probable cause, Alaska’s leading car-search case requires case-specific exigent circumstances (Clark v. State, 574 P.2d 1261 (Alaska 1978)).

Alaska: odor and the car — We found no published ruling on odor and car searches since 2015. And Alaska's leading case wants exigency, not just probable cause. — Alaska: odor and the car — the statute, the controlling cases, and what still gets you into the car. The full breakdown lives inside StreetSense, offline.

No odor statute — and what AS 17.38 legalized

AS 17.38 has no odor or search provision. For adults 21 and over, possessing, using, displaying, buying or transporting one ounce or less is lawful and is not “a basis for seizure or forfeiture of assets under state law” (AS 17.38.020). That language bars seizure and forfeiture; it says nothing about searches.
The Court of Appeals calls AS 17.38 “a narrow carve-out”: everything outside it is still controlled-substance law under AS 11.71 (Burns v. State, 543 P.3d 1013 (Alaska App. 2024)).

What is still illegal

More than one ounce: class A misdemeanor (AS 11.71.050(a)(5)). Delivering, or possessing with intent to deliver, one ounce or more: class C felony (AS 11.71.040(a)(2)).
Under 21: AS 17.38’s protection covers only adults 21 and over.
Consuming in public: a violation, fine up to $100 (AS 17.38.040).
DUI: AS 17.38 doesn’t change impaired-driving law (AS 17.38.220(b); AS 28.35.030).
Alaska has no marijuana open-container law. AS 28.35.029 covers alcohol only.

Crocker — odor shows marijuana, not a crime

Crocker (2–1), a home warrant: a “strong odor of growing marijuana” gave “ample probable cause” that marijuana was inside, but not that the amount was illegal. The application “must provide an affirmative reason to conclude that the possession is illegal.”
The court refused to “assume that there is a direct proportionality between the strength of the odor and the amount of marijuana.”
State v. Smith, 182 P.3d 651 (Alaska App. 2008), shows the fix: an officer’s experience, backed by data from his unit’s past cases, tied the odor to a commercial grow.
Both were home cases, decided under the older Ravin limits. We found no Alaska decision applying Crocker to a car, but the logic carries: tie the odor to something unlawful.

Clark — probable cause isn't enough

Clark (Alaska Supreme Court): a warrantless vehicle search needs probable cause “and” exigent circumstances, and exigency “is not automatically fulfilled merely because the object searched is an automobile.” It is judged on the facts of the search.
We found no decision overruling Clark and no Alaska decision adopting the federal rule that probable cause alone is enough (Maryland v. Dyson). In a 1982 footnote, the Court of Appeals said Alaska Supreme Court decisions “appear to adopt a more restrictive approach to the automobile exception” (Dunn v. State, 653 P.2d 1071 (Alaska App. 1982)).
In two published cases we found (Williams v. State, 139 P.3d 1282 (Alaska App. 2006); DeWeese v. State, 215 P.3d 1087 (Alaska App. 2009)), officers who smelled marijuana or got a dog alert secured the car and got a warrant.
Search incident to arrest is narrower too: an unlocked center console within the driver’s reach can be searched, but other items must be seized and a warrant obtained unless there is an exigency (Crawford v. State, 138 P.3d 254 (Alaska 2006)).

Under Article I, § 14, you can’t ask to search during a traffic stop for something unrelated to the stop without reasonable suspicion of criminality (Brown v. State, 182 P.3d 624 (Alaska App. 2008)). Questions about other crimes need reasonable suspicion and can’t unreasonably extend the stop (Duty v. State, 532 P.3d 742 (Alaska App. 2023)).
A dog sniff of luggage is a search under the Alaska Constitution, allowed on reasonable suspicion that drugs are present and are being illegally imported or held for distribution (Pooley v. State, 705 P.2d 1293 (Alaska App. 1985)). We found no Alaska decision on whether a sniff of a car’s exterior is a search, or on marijuana-trained dogs.

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.
Clark’s exigency rule (not revisited by the Alaska Supreme Court since 1979) and the Article I, § 14 cases sit above it.
That is the floor. Alaska courts have read the state constitution to require more, so work to Alaska’s rule.

How it plays out on the street

Midnight stop for a dead taillight. Adult driver, smell of burnt marijuana, nothing in view, no signs of impairment. Treat it as a legal amount until you can show otherwise — and under Brown, you don’t get to ask to search on a hunch. Write the taillight. Change the facts: the driver is 19 and you can tie the marijuana to him, or a vacuum-sealed brick sits on the back seat, or he can’t keep the car in its lane. Now you can articulate something unlawful. If it’s a search for evidence, Clark asks what the exigency is. If you can’t name one, secure the car and write the warrant.

Frequently asked questions

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

We found no published Alaska appellate decision on it since adults could legally possess an ounce in 2015. In home-warrant cases the Court of Appeals held that when some possession is lawful, odor shows marijuana is present but not that a crime is happening (State v. Crocker, 2004). Even with probable cause, Alaska’s leading car-search case, Clark v. State (1978), requires case-specific exigent circumstances or a warrant.

Does Alaska follow the federal automobile exception?

We found no Alaska decision adopting it. Clark v. State (Alaska 1978) requires probable cause plus exigent circumstances judged on the facts, and says exigency is not automatic just because the object is a car. We found no decision overruling it.

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

Adults 21 and over may possess and transport one ounce or less (AS 17.38.020). More than one ounce is a class A misdemeanor, and consuming marijuana in public is a violation with a fine of up to $100. Alaska has no marijuana open-container law.
