Missouri cannabis rules for visitors

Adults 21 and older, residents and visitors alike, may buy, possess and carry up to 3 ounces of dried, unprocessed marijuana or its equivalent, and may buy no more than 3 ounces in a single transaction (Missouri Constitution, Article XIV, Section 2.10; 19 CSR 100-1.040). State rules count 1 ounce of flower as 8 grams of concentrate or 800 milligrams of THC in infused products, so the cap equals 24 grams of concentrate or 2,400 milligrams of THC (19 CSR 100-1.010). Holding more than the limit but no more than twice it is a civil infraction with a penalty of up to $250 for a first violation, and registered home growers may keep larger harvests locked at their residence.

Dispensaries must check a valid, unexpired government-issued photo ID; Missouri sets no residency rule for adult-use buyers, and the 3-ounce limit is the same for everyone (19 CSR 100-1.180). Legal use is limited to private property where the owner allows it or a locally licensed area: legalization does not cover public use, smoking in a public place draws a civil penalty of up to $100, and hotels and other businesses may prohibit marijuana consumption and distribution on their property (Article XIV, Sections 2.1, 2.3, 2.10). Licensed dispensaries may deliver to an address that allows possession. Flights from STL and MCI, the Gateway Arch and other federal land, and trips across the state line fall under federal law, where adult-use marijuana remains Schedule I, and under the neighboring state's own rules; Kansas, Iowa and Nebraska penalize possession.

The regulator is the Missouri Department of Health and Senior Services, Division of Cannabis Regulation. Check any shop's license on the state license lookup before you buy.

Adults 21 and older may buy, possess and carry up to 3 ounces of dried, unprocessed marijuana or its equivalent, and 3 ounces is also the cap on a single purchase (Missouri Constitution, Article XIV, Section 2.10; 19 CSR 100-1.040). The limit is the same for residents and visitors. For concentrates and edibles, the Division of Cannabis Regulation's rules count 1 ounce of flower as 8 grams of concentrate or 800 milligrams of THC in infused products (19 CSR 100-1.010), so 3 ounces works out to 24 grams of concentrate or 2,400 milligrams of THC.

The ceiling applies to each transaction and to what you hold at any time. A dispensary may not sell or deliver more than 3 ounces or its equivalent in one transaction, checks each sale in the statewide track and trace system, and must report a customer it knows, or should know, is making several purchases in one day that would pass the possession limit (19 CSR 100-1.180). The constitution sets 3 ounces as the floor for any per-sale limit the Department adopts (Article XIV, Section 2.4(1)(m)).

Sharing is legal within limits. Adults may give 3 ounces or less to another adult 21 or older without payment, and may help another adult do anything the section allows (Article XIV, Section 2.10(1)); selling takes a state license. When counting edibles, the Department says the number that matters is the total THC in milligrams on the label, not the package weight. No statewide marijuana measure is on Missouri's August 4 or November 3, 2026 ballots, so the 2022 amendment stands as written (Secretary of State).

Hemp THC products are about to change. House Bill 2641, approved by the governor on April 23, 2026, treats hemp-derived cannabinoid products as marijuana that only state-licensed cannabis facilities may make and sell, effective November 12, 2026 for products with synthetic cannabinoids or cannabinoids manufactured outside the plant, smokable hemp flower containing THCA, and gummies, candies, tablets, capsules, oils, baked goods and other solid edibles with hemp delta-9 THC above natural levels; for other hemp products the state ban applies only while federal hemp restrictions prohibit them, and Public Law 119-103 limits those federal restrictions until December 11, 2026 to products with cannabinoids the plant cannot naturally produce; a final hemp product with more than 0.4 milligrams of total THC per container falls outside the new state definition of hemp (RSMo 195.900). Selling such products outside a licensed facility becomes a class D felony with a $5,000 fine per transaction.

You must be 21 or older. Missouri's constitution defines a consumer as a person at least 21 years of age (Article XIV, Section 2.2), and before any sale or delivery the dispensary must see a valid, unexpired government-issued photo ID and confirm the buyer is at least 21 (19 CSR 100-1.180(2)(D), 1.140(3)). No one under 21 may go past a dispensary's entry screening area unless they are a registered patient or are with a parent or guardian who is a patient, caregiver or adult customer.

Missouri sets no residency rule for adult-use purchases. The Department's FAQ gives examples of acceptable ID for consumers: a U.S. driver's license, a Missouri identification card, a U.S. passport book or card, or a U.S. military or military dependent ID, as long as it is not expired and shows a date of birth or age. Those are examples; the rule asks for a valid, unexpired government-issued photo ID without saying it must be issued in the United States, but no Department rule or FAQ addresses foreign passports. The rule calls for the ID itself to be produced at the time of sale or delivery (19 CSR 100-1.180(2)(D)).

Privacy protections are written into the constitution: the Department may not require a consumer to give a dispensary any identifying information other than identification to determine age (Article XIV, Section 2.7(4)). From November 12, 2026 a new statute goes further: a dispensary may not create or keep any record containing an adult customer's identifying information unless the customer agrees in writing, may not refuse service to someone who declines, and faces a $500 fine per violation (RSMo 195.819, enacted by House Bill 2641).

Underage possession of small amounts is a civil matter. A person under 21 found with 3 ounces or less faces a civil penalty of up to $100 and forfeiture, with the option of up to four hours of drug education or counseling instead of the fine (Article XIV, Section 2.10(5)). For more than 3 ounces but no more than twice the limit, the penalty for someone under 21 rises to as much as $250, with up to eight hours of education or counseling offered in its place (Section 2.10(6)(d)).

Legalization covers use on private property with the owner's permission, not public use. The constitution says legalization is not intended to allow public use of marijuana, and it leaves in place laws on consuming in public places, smoking where tobacco smoking is banned, and use on the grounds of schools, colleges and correctional facilities (Article XIV, Sections 2.1, 2.3(1)). Asked whether you can use marijuana in public, the Division of Cannabis Regulation answers 'Generally, no,' unless a local government allows it in certain areas.

Smoking in a public place, outside an area licensed for it by the local authority that permits such activity, carries a civil penalty of up to $100 (Article XIV, Section 2.10(4)). Section 2 does not define a public place, and the state park rules (10 CSR 90-2), which cover Lake of the Ozarks State Park and other state parks, do not mention marijuana, so state law does not spell out whether a given sidewalk, street, park, riverfront, festival ground or bar counts as public. The constitution also lets marijuana smoking be barred anywhere tobacco smoking is (Section 2.3(1)(h)).

Private owners set their own rules. Any business or other entity may ban or limit marijuana use on property it owns, leases, occupies or manages, which covers hotels, restaurants, venues and rental companies (Article XIV, Section 2.3(4)). One exception protects tenants: a lease signed after December 8, 2022 may not stop a tenant from lawfully possessing marijuana and using it by means other than smoking. Employers may still bar use at work and discipline anyone working while under the influence (Section 2.3(3)).

Cities and counties may write their own rules on the time and place marijuana may be smoked in public areas, and on eating infused products in designated areas, including dishes or drinks a restaurant prepares for same-day on-site consumption (Article XIV, Section 2.5(6)). Those ordinances differ by town, and we could not read the current St. Louis or Kansas City codes for this guide, so check the city code before assuming any patio, rooftop or event space is legal.

Only if the hotel allows it. Missouri's constitution lets any business prohibit or limit marijuana consumption, distribution, sale or display on property it owns, leases, occupies or manages (Article XIV, Section 2.3(4)), so a hotel may set its own no-cannabis or no-smoking policy. No state statute read for this guide bans marijuana in a closed guest room, and no Missouri law read for this guide says whether a guest room counts as a public place. Hotel policies on cannabis, vaping and smoking differ property by property.

Smoking is the harder case. Missouri's statewide indoor smoking law is written around burning tobacco and lets the person in charge of a public place set aside up to 30 percent of its space for smoking (RSMo 191.765, 191.767), but the constitution separately allows marijuana smoking to be banned anywhere tobacco smoking is banned (Article XIV, Section 2.3(1)(h)). Cities may have their own smoke-free ordinances, but no St. Louis or Kansas City ordinance text could be read for this guide, so the hotel's own policy is the practical rule.

Lobbies, hallways, pools, hotel bars and restaurants are open to the public, so smoking there risks the constitution's civil penalty of up to $100 for smoking marijuana in a public place (Article XIV, Section 2.10(4)), in addition to any action the hotel takes under its own rules. Edibles avoid the smoking rules but not the hotel's own policy. Branson lodges and Lake of the Ozarks resorts follow the same state rules, with house rules set property by property.

Vacation rentals depend on the owner. A short-term rental is private property, and the owner or the booking platform's terms may ban cannabis. The constitution protects lawful non-smoking use under a lease signed after December 8, 2022 (Section 2.3(4)), but we found no official guidance applying that clause to a nightly booking. Delivery to a hotel room is possible: licensed dispensaries may deliver to any address the customer gives that allows legal possession (19 CSR 100-1.140(3)), and because a hotel may prohibit the distribution and consumption of marijuana on its property (Article XIV, Section 2.3(4)), its ban can extend to deliveries.

Not under a state license. Missouri's constitution and the Division of Cannabis Regulation's rules create licenses for cultivation, manufacturing, testing, transportation and dispensaries, but no state on-site consumption license (Article XIV, Sections 2.2, 2.4; 19 CSR 100-1). The constitution leaves room for local approval instead: smoking in public is penalized except in an area licensed for that activity by the authorities that have jurisdiction over licensing or permitting it (Section 2.10(4)).

Cities and counties hold that power. Local governments may adopt ordinances on the time and place where marijuana may be smoked in public areas, and on consuming marijuana-infused products within designated areas, including culinary dishes or beverages prepared by local restaurants for on-site consumption on the same day (Article XIV, Section 2.5(6)). Any such rule must not conflict with the constitution or the Department's regulations. The Department's FAQ tells visitors to check with the local government on whether public use is permitted anywhere.

Dispensaries are not lounges. Asked whether customers may consume marijuana within or outside a dispensary, the Division of Cannabis Regulation answers no, citing the public-place limits in Sections 1 and 2 of Article XIV, and adds that local governments may designate areas for public consumption. The dispensary rule keeps marijuana inside secured limited access areas and sets a staffing ratio of one agent for every three customers there, with no provision for on-site use (19 CSR 100-1.180).

We found no St. Louis, Kansas City, Springfield, Columbia or Branson ordinance authorizing a consumption lounge that could be read on an official site as of October 16, 2026. St. Louis's city website did not answer our connection and Kansas City's code host refused it, so this guide names no lounge. Smoking outside a licensed area carries the $100 civil penalty.

Not while driving, and not while impaired. Missouri's constitution leaves in force laws against operating or being in physical control of a car, train, aircraft or motorboat while under the influence, and leaves consuming marijuana while operating one, or smoking it in one that is being operated, open to prohibition (Article XIV, Section 2.3(1)(d), (e), (f)). Rental car and rideshare companies may also ban cannabis in vehicles they own or manage (Section 2.3(4)).

Driving while intoxicated covers marijuana. Missouri defines an intoxicated condition as being under the influence of alcohol, a controlled substance or a drug (RSMo 577.001), and a first offense of driving while intoxicated is a class B misdemeanor (RSMo 577.010), punishable by up to six months in jail and a fine of up to $1,000 (RSMo 558.011, 558.002). The same class applies to a first offense of boating while intoxicated on Missouri lakes and rivers (RSMo 577.013).

Missouri sets no THC blood level. For drivers 21 and older, the constitution requires evidence that the person was in fact under the influence at the time, not just the presence of THC or THC metabolites in the body (Article XIV, Section 2.3(1)(d)). The odor of marijuana alone is not reasonable suspicion of a crime, except when police are investigating whether someone is operating a vehicle or boat under the influence (Section 2.10(10)), so the smell of smoke in a car still matters on the road.

Carrying is legal within the 3-ounce limit, because transporting is one of the acts the constitution protects for adults (Article XIV, Section 2.10(1)(a)). The constitution sets no open-container rule for marijuana, and dispensaries must sell every product in a child-resistant container (Section 2.9(5)). Every Missouri dispensary must post a sign at each exit and drive-through drawer warning that it is against the law to operate a motor vehicle, aircraft or motorboat while under the influence of marijuana (19 CSR 100-1.180).

Neither Missouri airport publishes cannabis rules, and federal law governs air travel. Neither St. Louis Lambert International, whose site credits the St. Louis Airport Authority and the City of St. Louis with its master plan, nor Kansas City International, managed by the Kansas City Aviation Department, has a page on cannabis or disposal boxes that we could find. Missouri's Indoor Clean Air Act lists airport waiting areas as public places for its own tobacco rules (RSMo 191.765), and the constitution, which sets a civil penalty of up to $100 for smoking marijuana in a public place, does not define the term (Article XIV, Section 2.10(4)).

The flight falls under federal law. TSA's medical marijuana page, updated April 27, 2026, now lists medical marijuana as allowed in carry-on and checked bags with special instructions, says officers do not search for illegal drugs but refer any illegal substance found during screening to law enforcement, and says the officer has the final decision at the checkpoint. Lambert's FAQ says the Department of Homeland Security decides what may go on board. The FAA's 2022 compliance letter, written before the April 28, 2026 DEA rule moved state-licensed medical marijuana to Schedule III, calls marijuana a Schedule I controlled substance and says its cultivation, storage or distribution on federally obligated airport property is prohibited regardless of state law.

Missouri's protection ends at the state line. Kansas City sits on the Kansas border, and in Kansas a first conviction for possessing marijuana is a class B nonperson misdemeanor (K.S.A. 21-5706), punishable by up to six months in jail and a fine of up to $1,000 (K.S.A. 21-6602, 21-6611); SB 295, a 2025-2026 session bill to replace criminal penalties for personal-use amounts with a civil penalty, died. Iowa punishes a first marijuana possession with up to six months in jail, a $1,000 fine or both (Iowa Code 124.401), and Nebraska fines a first offense of an ounce or less $300 (Neb. Rev. Stat. 28-416).

Illinois, across the Mississippi from St. Louis, allows adult use, but a visitor there may hold only 30 grams of flower, 5 grams of concentrate and 500 milligrams of THC (410 ILCS 705/10-10), well under Missouri's 3 ounces. Arkansas and Oklahoma run medical marijuana programs under the Arkansas Medical Marijuana Amendment of 2016 and Oklahoma's State Question 788 of 2018. Crossing any state line with cannabis also brings in federal law, where adult-use marijuana remains a Schedule I controlled substance (DEA final rule, April 28, 2026; 21 U.S.C. 844).

No. Federal law makes possessing marijuana a crime on all federal land, with up to a year in prison and a minimum fine of $1,000 for a first offense (21 U.S.C. 844), and the Park Service rule bars possessing a controlled substance in park units unless it was obtained from a practitioner or is otherwise allowed by federal or state law (36 CFR 2.35(b)(2)). Missouri's legalization does not reach federal ground. That covers Gateway Arch National Park in St. Louis, whose 2026 Superintendent's Compendium lists the park's added rules on smoking and alcohol under the same Title 36 sections.

Ozark National Scenic Riverways, the first national park area created to protect a river system, takes in the Current and Jacks Fork rivers, and its compendium also restricts smoking and alcohol in parts of the park. Other Park Service sites in Missouri include Harry S Truman National Historic Site in Independence and Grandview and George Washington Carver National Monument in Diamond. The same federal ban on controlled substances applies in each of them, including on float trips and in park campgrounds.

Mark Twain National Forest, the national forest in Missouri's Ozarks with more than 750 miles of trails, is federal land too, and federal drug law applies there as everywhere (21 U.S.C. 844). The 2026 federal rescheduling does not change this: a DEA final rule effective April 28, 2026 moved FDA-approved marijuana products and marijuana under a state medical marijuana license to Schedule III, and says any other form of marijuana remains a Schedule I controlled substance, which is where adult-use purchases fall.

The broader federal case is still open. The DEA's separate hearing on rescheduling marijuana ran from June 29 to July 15, 2026, and on September 29, 2026 the presiding administrative law judge stayed the case while a motion to add a GAO report to the record is decided; no final rule covering adult-use marijuana exists. This guide does not describe tribal land rules, because no tribal government or Interior Department source on tribal land in Missouri could be read.

Yes. Comprehensive and microbusiness dispensaries may deliver to adults 21 and older, and the constitution lets them take orders in person, by phone or online, including through a third party, and deliver to any address the customer directs (Article XIV, Section 2.2(4), (18)). The Division of Cannabis Regulation's rules allow delivery by the dispensary or a licensed transportation company to an address that allows legal possession of marijuana, and a dispensary needs Department approval before it starts delivering (19 CSR 100-1.140(3); DCR FAQ).

The checks happen at the door. The driver must see a valid, unexpired government-issued photo ID confirming the customer is at least 21 and record the delivery in the statewide track and trace system (19 CSR 100-1.140(3)(D)). The 3-ounce cap applies to each delivery as to each sale. Payment may be taken in advance or on delivery; if the order is not prepaid, the store may deliver to no more than two people at the same address on the same day, and payment is refundable if the delivery cannot be completed (19 CSR 100-1.180(2)(D)).

Hotel delivery depends on the hotel. The rule limits delivery to an address that allows legal possession, and the constitution lets a business prohibit the distribution or consumption of marijuana on property it owns or manages (Article XIV, Section 2.3(4)), so a hotel that bans cannabis can refuse a delivery on its premises. Drive-through windows are allowed if they use drawers or pneumatic tubes and keep the customer in clear view on camera (19 CSR 100-1.180(2)(A)). Curbside pickup is not yet allowed: the Department filed a proposed rule to create it on July 29, 2026, with public comments taken from September 1 to October 1, 2026.

Yes, if you register first. An adult 21 or older who holds a consumer personal cultivation card from the Department may grow up to six flowering plants, six nonflowering plants over 14 inches tall and six clones under 14 inches (Article XIV, Section 2.10(1)(b); 19 CSR 100-1.040(5)). The card costs $115.68 for applications from July 1, 2026 to June 30, 2027 (DCR fee schedule) and is valid for 12 months and renewable (19 CSR 100-1.040(5)(H); DCR Adult Use FAQ).

Growing must happen at a private residence, never at a place of business, inside an enclosed, locked space with security devices and with plants out of view from any public space (19 CSR 100-1.010, 1.040(5)). Up to two card holders may grow at the same residence, but no residence may hold more than 12 flowering plants, 12 nonflowering plants of 14 inches or more and 12 under 14 inches, and each flowering plant must carry the grower's name. The card must be displayed near the plants.

Any harvest above the 3-ounce carry limit must stay at the residence in the locked space (Article XIV, Section 2.10(1)(b); 19 CSR 100-1.040(4)). Plants visible from a public place, or not kept locked, bring a civil penalty of up to $250 and forfeiture (Section 2.10(2), (3)). The rules create no right to grow where state law or a private contract, such as a lease, forbids it, and dispensaries may sell plants only to card holders, no more than six a day (19 CSR 100-1.040(5)(E), 1.180(2)(F)).

A visitor's options are limited. The cultivation card lists the address where the holder is authorized to grow (19 CSR 100-1.040(5)(G)), and the rules require a private residence, so a hotel room will not qualify. Registered medical patients may hold a patient cultivation card instead, priced at $57.83 in the same fee year, but a patient may not hold patient and consumer cultivation authority at the same time (19 CSR 100-1.040(5)(C); DCR fee schedule).

Adult-use cannabis pays a 6 percent state marijuana tax on the retail price, collected by the dispensary for the Department of Revenue (Article XIV, Section 2.6(1)). That tax is separate from and in addition to the general state and local sales taxes on retail sales (Section 2.6(4)), and the state sales tax rate is 4.225 percent (Department of Revenue). Local governments may add up to 3 percent more on adult-use sales once their voters approve it (Section 2.6(5)), and no other taxes may be imposed on marijuana sales (Section 2.6(6)).

Only one local marijuana tax applies at a given store. The Department of Revenue says the Missouri Supreme Court ruled on July 22, 2025 that a county may impose its additional adult-use tax only in unincorporated areas, so inside city limits the city's tax is the one that applies. The Department's local table lists a 3 percent tax in Kansas City and Columbia from October 1, 2023, and in St. Louis city, Springfield and Branson from January 1, 2024.

For the quarter starting October 1, 2026, the Department's rate file lists general sales tax rates of 9.679 to 11.679 percent and adult-use marijuana rates of 12.679 to 14.679 percent in St. Louis city, depending on special taxing districts, the difference in each case being the city's 3 percent. Kansas City's adult-use rate runs from 11.725 to 14.975 percent depending on the county and special districts, Springfield's from 11.1 to 13.6 percent, Columbia's from 10.975 to 11.975 percent and Branson's from 11.35 to 14.35 percent. The 6 percent state marijuana tax is added in every case.

Medical purchases are taxed differently. Sales to registered patients and caregivers pay a 4 percent state tax instead of the 6 percent adult-use tax (Article XIV, Sections 1.4(1), 2.6(1)), and the Department's market study notes that the rate follows the type of transaction, not the store's license. The local 3 percent applies only to adult-use sales (Section 2.6(5)). Adult-use tax money goes first to running the program and expungements, then in thirds to veterans' services, drug addiction treatment grants and the public defender system (Section 2.6(2)).

Yes, at the dispensary's option. Missouri's constitution says a substantially equivalent patient card or authorization issued by another state allows a non-resident patient to buy medical marijuana from a Missouri dispensary, in line with the Department's rules (Article XIV, Section 1.5(1)). The dispensary rule lets a store accept a substantially equivalent identification card issued in another jurisdiction along with valid photo ID (19 CSR 100-1.180(2)(D)), and the Department's FAQ says licensed dispensaries may accept out-of-state cards.

Visitors 21 and older can simply buy as adult-use customers, under the 3-ounce limit and the 6 percent adult-use tax. Missouri's own patients buy under the medical program: up to 6 ounces of dried, unprocessed marijuana or its equivalent in 30 days unless a certifying physician or nurse practitioner authorizes more, possession of up to a 60-day supply, and a 4 percent state tax (19 CSR 100-1.040(4); DCR FAQ). A patient may not combine patient and consumer purchases to go past those limits.

Missouri no longer requires state residency for its own patient card. The Department's FAQ says proof of Missouri residency is not required, but every application needs a certification from an MD, DO or nurse practitioner licensed and in good standing in Missouri, signed less than 30 days before the application is submitted (19 CSR 100-1.040(2)(B)). Patient cards cost $28.92 in the fee year that began July 1, 2026, are valid for three years, and are printed from the online registry rather than mailed.

Non-emancipated patients under 18 must have a parent or legal guardian as their caregiver, and caregivers must be 21 or older and may serve up to six patients (19 CSR 100-1.040(2), (3)). From November 12, 2026, a new statute bars state agencies and their employees from giving the federal government or unauthorized third parties the list of patient and caregiver card holders, or any individual's information, without a subpoena or court order, and a knowing violation is a class E felony (RSMo 195.800, enacted by House Bill 2641).

Most visitor trouble is a civil fine. Smoking marijuana in a public place outside a licensed area carries a civil penalty of up to $100 (Article XIV, Section 2.10(4)). Possession of 3 ounces or less by someone under 21 carries up to $100 and forfeiture, with drug education offered in place of the fine (Section 2.10(5)). A home grower whose plants are visible from a public place, or not locked up, faces up to $250 and forfeiture (Section 2.10(2), (3)).

Going over the limit is graded. An adult holding more than 3 ounces but no more than twice the limit commits a civil infraction with a penalty of up to $250 for a first violation and up to $500 for a second, and a misdemeanor with a fine of up to $1,000 for a third or later one, with forfeiture each time (Article XIV, Section 2.10(6)). The same scale covers giving away up to twice the limit, and the penalties may be worked off with community service at a pay-down rate of the greater of $15 or the minimum wage.

The constitution's civil penalty scale stops at twice the limit and does not say what applies above it, while it separately protects larger amounts held by registered patients and by registered home growers at their residence (Article XIV, Sections 1.5(1), 2.10(1)(b)). Missouri's possession statute, last amended in 2016, before legalization, makes possessing more than 35 grams of marijuana a class D felony (RSMo 579.015), punishable by up to seven years in prison and a fine of up to $10,000 (RSMo 558.011, 558.002). Selling without a license is delivery of a controlled substance: a class E felony, with up to four years in prison, for 35 grams or less, and a class C felony above that (RSMo 579.020).

Driving while intoxicated on marijuana is a class B misdemeanor for a first offense (RSMo 577.010), with up to six months in jail. The hemp law adds felony exposure for sellers: from November 12, 2026, using the word 'dispensary' in the name of an unlicensed shop selling CBD, hemp or cannabinoid products, or selling covered hemp-derived cannabinoid products outside a licensed facility, is a class D felony with a $5,000 fine per transaction, and for hemp products outside the law's four listed categories the sales ban applies only while federal hemp restrictions prohibit them (RSMo 195.900). Licensed stores, by contrast, may sell only products that passed mandatory state testing (19 CSR 100-1.180).

The Department advises checking its licensed dispensary map before visiting a store. The Division of Cannabis Regulation publishes a Verified Dispensary Locator map, and its data layer, last updated October 6, 2026, lists 238 dispensary licenses: 224 medical or comprehensive licenses numbered DIS and 14 microbusiness dispensary licenses numbered MBD. Of those, 227 show a street address; the Department says that in its licensee contact list dashboard, dispensary licensees that are not approved to operate or have no facility location are listed without an address. Its licensee dashboard also lists every active license by number and trade name.

A licensed store shows it. The Department says to look for its 'Verified Dispensary: We're on the List' decal in the window, whose QR code opens the map, or a state license inside. Products must come in child-resistant packaging, may not use realistic or cartoon human, animal or fruit shapes or mimic candy brands, and carry a license number beginning MAN, CUL, DIS, MBW, MBD or TES that shows which licensed facility grew, made or tested them. Staff agent ID cards can be checked by their QR code.

Inside, the layout is set by rule. Everyone enters through one public access point where staff check age or patient status, no marijuana is accessible in that area, and the sales floor needs at least one agent for every three customers (19 CSR 100-1.180(2)(A)). Every product sold must have passed mandatory testing and must not be on hold or recalled in the statewide tracking system (19 CSR 100-1.180(2)(B)). The Department notes that cannabis sold in Missouri's regulated market must be grown, made, tested and transported within the state.

Gas stations and smoke shops selling delta-8, THCA or other hemp-derived products are not licensed dispensaries; the Department says such products have not been made in a licensed facility or tested by a licensed lab. That changes on November 12, 2026, when House Bill 2641 bars any unlicensed seller of CBD, hemp or cannabinoid products from using the word 'dispensary' in its name and brings most hemp-derived cannabinoid products under the marijuana framework, with other hemp products covered only while federal hemp restrictions prohibit them (RSMo 195.900). The Department's call center, 866-219-0165, can confirm a license.
