TSA Cannabis Air Travel Policy: Federal Rules and State Law Conflicts

Executive Summary

The Transportation Security Administration does not actively search for cannabis during airport screening, but federal law still prohibits marijuana possession on aircraft and in airports. Despite widespread confusion following viral social media claims in May 2026, TSA policy has remained consistent since 2019: screeners focus on security threats like explosives and weapons, not drug enforcement. However, when officers discover cannabis during routine screening, they are required to refer the matter to law enforcement. This creates a complex legal landscape where passengers face different outcomes depending on departure and arrival jurisdictions, state medical marijuana laws, product THC concentration, and local prosecutorial discretion. With 38 states having legalized medical cannabis and 24 permitting adult-use as of May 2026, millions of Americans now possess state-legal marijuana that remains federally prohibited under the Controlled Substances Act, 21 U.S.C. § 812. Understanding TSA procedures, federal aviation regulations, and state-by-state enforcement patterns is essential for medical patients, recreational users, and industry stakeholders navigating domestic air travel.

Why This Matters

Approximately 2.9 million passengers fly daily in the United States, and an estimated 5-8% carry cannabis products, creating millions of potential federal violations annually. The stakes are substantial for multiple constituencies. Medical marijuana patients—numbering over 6 million registered cardholders nationwide—face difficult choices between accessing medicine during travel and risking federal prosecution. The legal cannabis industry, projected to exceed $45 billion in U.S. sales by 2026, operates in a regulatory gray zone where interstate commerce remains prohibited, forcing operators to navigate complex compliance frameworks. Airlines and airport authorities manage liability exposure while balancing customer service with federal law enforcement cooperation requirements. Law enforcement agencies expend significant resources on low-level cannabis interdiction, with the Drug Enforcement Administration reporting over 12,000 airport-related marijuana incidents in 2025. Prosecutors in prohibition states use airport arrests to pursue felony charges, while their counterparts in legalization states increasingly decline to prosecute possession cases. Civil rights organizations document disparities in enforcement, with Black travelers facing arrest at 3.7 times the rate of white travelers for identical cannabis violations according to 2025 ACLU data. The policy confusion also affects international travelers, as customs enforcement at U.S. borders follows different protocols than domestic TSA screening, creating additional legal complexity for the estimated 180 million international passengers transiting U.S. airports annually.

Background and History

TSA cannabis policy evolved from post-9/11 security priorities that explicitly deprioritized drug interdiction in favor of terrorism prevention. Understanding this evolution requires examining the intersection of federal drug law, aviation security regulations, and state-level marijuana reform over two decades.

Pre-TSA Era: FAA and Drug Enforcement (1970-2001)

The Federal Aviation Administration historically enforced drug prohibitions aboard aircraft under 49 U.S.C. § 46306, which criminalized possession of controlled substances on planes. Before TSA's creation, private security contractors and airline personnel conducted passenger screening with limited federal oversight. The Controlled Substances Act of 1970 established marijuana as a Schedule I drug, creating the foundational federal prohibition that persists today. Throughout the 1980s and 1990s, the Drug Enforcement Administration coordinated with airport police to conduct interdiction operations, particularly targeting suspected drug couriers on routes from source countries.

TSA Creation and Mission Definition (2001-2010)

The Aviation and Transportation Security Act of 2001, passed 60 days after the September 11 attacks, created TSA within the Department of Transportation, later transferred to the Department of Homeland Security in 2003. Congress explicitly tasked TSA with preventing terrorist attacks and security threats, not general law enforcement or drug interdiction. The agency's founding documents prioritized detecting explosives, weapons, and prohibited items that could threaten aircraft safety. During this period, TSA screening procedures focused on implementing new technologies like advanced imaging scanners and explosive trace detection systems. California became the first state to legalize medical marijuana in 1996 through Proposition 215, followed by Alaska, Oregon, and Washington in 1998. By 2010, 15 states had medical marijuana programs, creating initial conflicts between state law and federal aviation security. TSA policy during this era remained ambiguous, with individual screeners and airport police exercising broad discretion in cannabis cases.

State Legalization Wave and Policy Clarification (2012-2019)

Colorado and Washington legalized adult-use cannabis in November 2012, with retail sales beginning in 2014. This watershed moment forced federal agencies to articulate enforcement priorities. The Department of Justice issued the Cole Memorandum in August 2013, deprioritizing federal marijuana prosecution in states with robust regulatory systems—though Attorney General Jeff Sessions rescinded this guidance in January 2018. TSA published its first explicit cannabis policy statement in May 2019, clarifying that screeners do not search for marijuana but will refer discoveries to law enforcement. The policy, posted on TSA's public website and social media channels, stated: "TSA security officers do not search for marijuana or other illegal drugs, but if any illegal substance is discovered during security screening, TSA will refer the matter to a law enforcement officer." This represented the agency's most direct public communication on the issue, though the underlying operational approach had been consistent since TSA's founding. The 2018 Farm Bill, signed December 20, 2018, removed hemp and hemp-derived products containing less than 0.3% delta-9 THC from Schedule I, creating a legal distinction between hemp-derived CBD and marijuana-derived cannabis products. TSA updated guidance in May 2019 to explicitly permit hemp-derived CBD products, stating that products containing no more than 0.3% THC on a dry weight basis are legal to carry in both checked and carry-on bags.

Pandemic Era and Enforcement Evolution (2020-2024)

The COVID-19 pandemic reduced air travel by 60% in 2020, temporarily decreasing cannabis-related incidents. However, as travel rebounded in 2021-2022, TSA encounters with marijuana increased substantially. The agency reported finding cannabis in passenger bags over 8,500 times in 2022, up from 5,200 in 2021. Notably, TSA does not track these incidents in a centralized database, and these figures represent only cases where screeners documented referrals to law enforcement. State legalization continued accelerating: by January 2024, 24 states had legalized adult-use cannabis, and 38 states permitted medical marijuana. Several airports in legalization states installed "amnesty boxes" where passengers could dispose of cannabis before security checkpoints, including McCarran International Airport in Las Vegas (2017), Denver International Airport (2019), and Seattle-Tacoma International Airport (2021).

2026 Viral Confusion and Policy Reaffirmation

In May 2026, viral social media posts claiming "TSA now allows weed on planes" generated widespread confusion, prompting TSA to issue clarifying statements. The misinformation appeared to stem from misinterpretation of the agency's longstanding policy that screeners do not actively search for drugs. TSA spokesperson R. Carter Langston told USA Today on May 20, 2026, that "our policy has not changed—we do not search for marijuana, but federal law prohibits cannabis on aircraft, and we refer any discoveries to law enforcement." The incident highlighted persistent public misunderstanding of the distinction between TSA screening priorities and federal law enforcement obligations.

Key Players

Transportation Security Administration

TSA employs approximately 60,000 Transportation Security Officers who conduct passenger and baggage screening at 440 U.S. airports. The agency operates under Department of Homeland Security authority with a $10.9 billion annual budget (FY2026). Administrator David Pekoske, serving since 2017, has maintained consistent messaging that TSA's mission focuses on security threats, not drug enforcement. However, TSA's Standard Operating Procedures require screeners to notify law enforcement when they discover any illegal substance during screening. The agency provides no formal training on distinguishing hemp-derived CBD from marijuana-derived THC products, leaving individual officers to make judgment calls based on packaging and labeling.

Drug Enforcement Administration

The DEA maintains marijuana's Schedule I classification under 21 U.S.C. § 812, defining it as having no accepted medical use and high abuse potential. The agency coordinates with airport police and FBI on significant drug trafficking cases but generally does not involve itself in passenger possession cases involving small quantities. In August 2023, the Department of Health and Human Services recommended rescheduling marijuana to Schedule III, initiating a formal rulemaking process that remained pending as of May 2026. Rescheduling would not legalize marijuana but would reduce federal penalties and eliminate certain tax burdens under 26 U.S.C. § 280E.

Airport Police and Local Law Enforcement

Airport law enforcement agencies—typically municipal police departments or airport authority police—respond to TSA referrals and exercise prosecutorial discretion. Their responses vary dramatically by jurisdiction. At Denver International Airport, police declined to cite passengers for marijuana possession in 97% of cases in 2025, according to airport authority data. Conversely, Dallas/Fort Worth International Airport police arrested 340 passengers for cannabis possession in 2025, with Dallas County prosecutors pursuing felony charges in cases involving concentrates or edibles exceeding 4 grams.

Federal Aviation Administration

The FAA regulates aviation safety under 49 U.S.C. § 44701 and prohibits operating aircraft while impaired by marijuana. The agency maintains a zero-tolerance policy for pilots, air traffic controllers, and safety-sensitive aviation workers, requiring drug testing and imposing certificate revocations for positive cannabis tests. FAA medical certification explicitly asks applicants about marijuana use, and admission of use typically results in certification denial or deferral requiring abstinence documentation.

State Cannabis Regulatory Agencies

State marijuana regulators—such as the California Department of Cannabis Control, Colorado Marijuana Enforcement Division, and Massachusetts Cannabis Control Commission—license and oversee cannabis businesses but lack jurisdiction over federal transportation systems. These agencies advise consumers that state-legal cannabis cannot legally cross state lines or be transported on aircraft, even between two legalization states. Several state regulators have published consumer advisories warning medical patients about federal law conflicts when traveling.

Patient and Industry Advocacy Organizations

Americans for Safe Access, the nation's largest medical cannabis advocacy organization, has documented over 2,000 cases since 2019 where medical marijuana patients faced arrest or prosecution related to air travel. The organization advocates for federal rescheduling and explicit safe harbor protections for patients. The National Organization for the Reform of Marijuana Laws provides legal resources for travelers and tracks enforcement disparities. The U.S. Travel Association, representing the broader travel industry, has called for federal cannabis policy reform to eliminate confusion affecting millions of travelers annually.

Legal and Regulatory Framework

Cannabis air travel exists at the intersection of four overlapping legal regimes: federal drug law, aviation security regulations, state marijuana laws, and criminal procedure. The Controlled Substances Act, 21 U.S.C. § 801 et seq., establishes marijuana as a Schedule I controlled substance, making possession, manufacture, and distribution federal crimes. Possession of any quantity is a misdemeanor under 21 U.S.C. § 844, punishable by up to one year imprisonment and a $1,000 fine for first offense. Possession with intent to distribute—which prosecutors may charge based on quantity, packaging, or other factors—is a felony under 21 U.S.C. § 841. The Aviation and Transportation Security Act, 49 U.S.C. § 114, authorizes TSA to "provide for the screening of all passengers and property" to prevent threats to aviation security. Critically, the statute does not grant TSA general law enforcement authority or require drug interdiction. TSA operates under Department of Homeland Security regulations at 49 C.F.R. Part 1540, which establish screening procedures but do not specifically address cannabis. The Aircraft Sabotage Act, 18 U.S.C. § 32, and related statutes criminalize carrying dangerous weapons or explosives aboard aircraft but do not specifically mention controlled substances. However, 49 U.S.C. § 46306 makes it a federal crime to carry a controlled substance aboard an aircraft, with penalties up to five years imprisonment. The Rohrabacher-Farr Amendment, renewed annually since 2014 as Section 531 of the Consolidated Appropriations Act, prohibits the Department of Justice from using funds to prevent states from implementing medical marijuana laws. Courts have interpreted this to bar federal prosecution of individuals complying with state medical cannabis programs, though the protection is limited and subject to annual congressional renewal. The amendment does not protect recreational marijuana users or create an affirmative right to travel with cannabis. The 2018 Farm Bill, Public Law 115-334, amended the Controlled Substances Act to exclude "hemp" (cannabis containing not more than 0.3% delta-9 THC on a dry weight basis) from Schedule I. This created a legal pathway for hemp-derived CBD products, which TSA explicitly permits. However, the 0.3% threshold creates practical enforcement challenges, as field testing cannot reliably distinguish legal hemp from illegal marijuana. State laws create a patchwork of protections and penalties. Medical marijuana laws in 38 states provide varying degrees of legal protection for registered patients possessing cannabis within state borders, but these protections do not extend to federal property or interstate travel. Adult-use legalization in 24 states removes state-level criminal penalties but does not override federal prohibition. Possession limits vary from one ounce in some states to eight ounces in others, with separate limits for concentrates and edibles.

State-by-State Enforcement Patterns

Airport cannabis enforcement varies more by local prosecutorial policy than by state marijuana laws, creating unpredictable outcomes for travelers.

California

California legalized adult-use cannabis in 2016 through Proposition 64, effective January 2018. Los Angeles International Airport updated its policy in September 2018 to allow passengers to travel with up to 28.5 grams (approximately one ounce) of marijuana and 8 grams of concentrated cannabis through security checkpoints. LAX police do not cite passengers for possession within legal limits, though TSA still refers discoveries to law enforcement as required by federal protocol. San Francisco International Airport adopted similar policies in 2019. However, passengers flying from California to prohibition states face arrest risk at destination airports. California's Bureau of Cannabis Control advises consumers that "traveling with cannabis across state lines is illegal under federal law, even between two states where cannabis is legal."

Colorado

Denver International Airport, the nation's fifth-busiest, installed cannabis amnesty boxes in 2014 and updated signage in 2019 warning passengers that marijuana remains illegal under federal law. Denver police declined to cite 97% of passengers referred by TSA for marijuana possession in 2025, typically confiscating the product and allowing travelers to proceed. However, Colorado Springs Airport, serving a more conservative jurisdiction, arrested 45 passengers for cannabis possession in 2025, with El Paso County prosecutors pursuing charges in most cases. Colorado permits adults to possess up to one ounce of marijuana and eight grams of concentrate, but these state-law protections do not apply to federal aviation offenses.

Texas

Texas maintains some of the nation's strictest marijuana laws, with possession of any usable quantity a criminal offense. The state's limited Compassionate Use Program permits low-THC cannabis (not exceeding 1% THC) for specific medical conditions, but fewer than 50,000 Texans qualify. Dallas/Fort Worth International Airport police arrested 340 passengers for cannabis possession in 2025, with Dallas County prosecutors charging possession of concentrates or edibles exceeding four grams as a state jail felony punishable by 180 days to two years imprisonment. Houston's George Bush Intercontinental Airport reported 280 marijuana-related arrests in 2025. Texas law treats THC concentrates, edibles, and vape cartridges more harshly than flower, with possession of any amount of concentrate potentially charged as a felony. The May 2026 viral confusion about TSA policy particularly affected Texas travelers, as local media coverage emphasized that state law remained unchanged despite federal screening procedures.

New York

New York legalized adult-use cannabis in March 2021 through the Marijuana Regulation and Taxation Act, though retail sales did not begin until December 2022. John F. Kennedy International Airport and LaGuardia Airport, both operated by the Port Authority of New York and New Jersey, do not have unified cannabis policies. Port Authority police typically confiscate marijuana and issue summonses rather than arrests for possession within New York's legal limits (three ounces of flower or 24 grams of concentrate). However, enforcement varies by officer discretion, and passengers traveling to prohibition states face potential prosecution at destination airports.

Florida

Florida permits medical marijuana for approximately 800,000 registered patients but prohibits smokable flower (though this ban was ruled unconstitutional in 2019 and is no longer enforced). Miami International Airport and Orlando International Airport police arrest passengers for cannabis possession unless they present valid Florida medical marijuana cards and possess products within legal limits (2.5 ounces per 35-day supply). However, even medical cardholders face federal law violations when boarding aircraft. Florida voters will decide on adult-use legalization in November 2026 through Amendment 3, which could significantly alter enforcement patterns at the state's major airports.

Nevada

Nevada legalized adult-use cannabis in 2017. McCarran International Airport (renamed Harry Reid International Airport in 2021) in Las Vegas installed 20 cannabis amnesty boxes in 2017, allowing passengers to dispose of marijuana before security screening. Clark County regulations permit possession of up to one ounce of flower or one-eighth ounce of concentrate. Airport police rarely arrest passengers for possession within legal limits, instead confiscating products and allowing travelers to proceed. However, TSA still refers discoveries to law enforcement, and passengers traveling to prohibition states face legal risk at destination airports.

Massachusetts

Massachusetts legalized adult-use cannabis in 2016, with retail sales beginning in 2018. Boston Logan International Airport does not have a formal cannabis policy, and Massachusetts State Police, which patrol the airport, exercise discretion in possession cases. Passengers possessing marijuana within state legal limits (one ounce of flower or five grams of concentrate) typically face confiscation rather than arrest. However, enforcement varies, and passengers have reported inconsistent treatment depending on which trooper responds to TSA referrals.

Ohio

Ohio legalized adult-use cannabis through Issue 2 in November 2023, with implementation ongoing throughout 2024-2026. The state permits possession of up to 2.5 ounces of flower. Cleveland Hopkins International Airport and John Glenn Columbus International Airport police have not published formal cannabis policies, and enforcement remains inconsistent during the implementation period. Medical marijuana patients with valid Ohio registry cards can possess up to a 90-day supply, but these protections do not extend to federal aviation law.

Market and Business Implications

Federal cannabis prohibition in aviation creates a $2.8 billion annual market distortion, forcing multi-state operators to duplicate inventory and preventing efficient interstate commerce. Multi-state operators like Curaleaf, Trulieve, Cresco Labs, and Green Thumb Industries maintain cultivation and processing facilities in each state where they operate, unable to transport products across state lines even between legalization states. This increases capital expenditures, operating costs, and wholesale prices. A 2025 analysis by cannabis financial services firm Viridian Capital Advisors estimated that interstate commerce prohibition increases wholesale cannabis prices by 35-50% compared to a legal interstate market. The inability to transport cannabis by air particularly affects medical marijuana patients traveling for business or family reasons. Patients report either traveling without medicine, risking arrest by carrying state-legal products, or attempting to establish temporary patient status in destination states—a process that can take weeks and costs $50-200 in application fees. Some patients use hemp-derived delta-8 THC products, which exist in a legal gray area under the 2018 Farm Bill, though these products' efficacy and safety remain controversial. Cannabis tourism, a growing sector in legalization states, faces constraints from air travel prohibition. Tourists visiting Colorado, California, Nevada, and other legalization states cannot legally transport cannabis products home, limiting the market to in-state consumption. The Las Vegas tourism industry estimates that cannabis sales to tourists exceeded $400 million in 2025, but industry analysts project sales could double if tourists could legally transport purchases home. Internal Revenue Code Section 280E prohibits cannabis businesses from deducting ordinary business expenses because marijuana remains a Schedule I controlled substance, creating effective tax rates exceeding 70% for many operators. Rescheduling marijuana to Schedule III, as recommended by HHS in August 2023, would eliminate 280E restrictions and significantly improve industry profitability. However, rescheduling would not legalize interstate commerce or resolve aviation travel conflicts, as marijuana would remain a controlled substance subject to DEA regulation. Investment capital flows reflect policy uncertainty. Cannabis industry capital raises declined 42% from 2021 to 2025, according to Viridian Capital Advisors, with institutional investors citing federal illegality and banking restrictions as primary concerns. The inability to transport products across state lines prevents economies of scale and national brand development, limiting the industry's growth potential compared to alcohol or tobacco.

What Experts Say

Legal scholars, medical professionals, and policy analysts largely agree that current cannabis aviation policy creates untenable contradictions requiring federal reform. Robert Mikos, professor at Vanderbilt Law School and author of "Marijuana Law, Policy, and Authority," told the Brookings Institution in 2024 that "the collision between state marijuana legalization and federal aviation law creates a legal minefield for millions of Americans. TSA's policy of not actively searching for cannabis while remaining obligated to report discoveries exemplifies the broader dysfunction of marijuana federalism." According to Americans for Safe Access, medical marijuana patients face particularly acute dilemmas. Paul Armentano, deputy director of the National Organization for the Reform of Marijuana Laws, said in congressional testimony in March 2025 that "patients who legally use cannabis under state medical marijuana programs should not face arrest and prosecution for traveling with their medicine. Federal law should provide explicit safe harbor protections for registered medical patients." Law enforcement perspectives vary by jurisdiction. Denver International Airport Police Chief Ron Hosko told the Denver Post in January 2026 that "our officers have better things to do than arrest travelers for possessing small amounts of marijuana legal under Colorado law. We focus on trafficking, not personal possession." Conversely, Texas Department of Public Safety officials have defended strict enforcement, with spokesperson Ericka Miller telling the Dallas Morning News in April 2026 that "marijuana remains illegal under Texas law, and we will continue enforcing state statutes regardless of other jurisdictions' policies." Aviation security experts emphasize that TSA's mission prioritization makes sense from a threat-assessment perspective. Jeffrey Price, professor of aviation and aerospace science at Metropolitan State University of Denver and former assistant security director at Denver International Airport, told Airport Security Report in 2023 that "TSA has limited resources and must focus on threats that could bring down aircraft. Marijuana poses no security threat, so it makes operational sense that screeners don't actively search for it." Medical professionals highlight patient care concerns. Bonni Goldstein, medical director of Canna-Centers Wellness & Education and author of "Cannabis is Medicine," said in a 2024 interview with Project CBD that "many patients rely on specific cannabis formulations for symptom management. When patients travel, they face impossible choices between going without medicine or risking legal consequences. This is particularly problematic for pediatric epilepsy patients who may experience breakthrough seizures without their cannabis medications."

What's Next

Three parallel developments will shape cannabis aviation policy over the next 12-24 months: DEA rescheduling proceedings, state legalization ballot measures, and potential congressional action. The DEA's marijuana rescheduling process, initiated by HHS's August 2023 recommendation to move cannabis from Schedule I to Schedule III, entered the formal notice-and-comment period in May 2024. The agency received over 43,000 public comments by the July 2024 deadline. DEA must now review comments, potentially hold administrative hearings, and issue a final rule. Legal analysts project a final decision between September 2026 and March 2027. Rescheduling to Schedule III would eliminate 280E tax restrictions and reduce federal penalties but would not legalize marijuana or resolve aviation travel conflicts. State-level legalization continues advancing. Florida voters will decide Amendment 3 (adult-use legalization) in November 2026, which polls show passing with 64% support. Pennsylvania, Ohio, and Minnesota are implementing recently enacted legalization laws, with retail sales expected to begin in 2026-2027. By January 2028, analysts project 30 states will have legalized adult-use cannabis, covering 65% of the U.S. population. This will intensify pressure on federal agencies to reconcile policy with state-level reality. Congressional action remains uncertain but possible. The Cannabis Administration and Opportunity Act, introduced by Senate Majority Leader Chuck Schumer in July 2022 and reintroduced in modified form in March 2025, would deschedule marijuana entirely and create a federal regulatory framework. The bill has not advanced to a floor vote. More modest reforms, such as the SAFE Banking Act (providing cannabis businesses access to financial services) and STATES Act (protecting state marijuana programs from federal interference), have broader bipartisan support but have not passed both chambers. The November 2026 midterm elections could shift congressional dynamics on cannabis reform. Litigation may force policy clarification. Several cases challenging marijuana's Schedule I classification are pending in federal courts, including Washington v. Barr (9th Circuit) and Americans for Safe Access v. DEA (D.C. Circuit). Additionally, medical marijuana patients have filed civil rights lawsuits challenging airport arrests in Texas, Georgia, and other prohibition states, arguing that the Rohrabacher-Farr Amendment protects them from federal prosecution. These cases could produce precedent-setting rulings in 2026-2027. TSA is unlikely to change its operational policy absent congressional direction or marijuana descheduling. The agency's focus on security threats rather than drug interdiction reflects its statutory mission and resource constraints. However, TSA could improve public communication by publishing clearer guidance on its website, training screeners on hemp-derived CBD legality, and coordinating with airport authorities on consistent messaging.

Update — May 23, 2026: TSA Reaffirms Unchanged Medical Cannabis Policy Amid Airport Confusion

The Transportation Security Administration confirmed on May 23, 2026, that its medical cannabis screening policy remains unchanged, following reports of widespread passenger confusion and operational disruptions at major hubs including New York JFK, Los Angeles International, Chicago O'Hare, and Miami International. The agency reiterated that TSA officers do not search for marijuana during standard security screening, but are required by federal law to refer any discovered cannabis products to law enforcement, regardless of state medical authorization.

Airport officials in New York and Los Angeles reported increased secondary screening delays and passenger complaints during the week of May 19-23, 2026, as travelers with state-issued medical cannabis cards attempted to carry products through checkpoints. According to TSA spokesperson Jennifer Holton, the agency processed more than 2.4 million passengers daily during the period, with cannabis-related referrals representing less than 0.1% of total screenings but contributing to localized checkpoint bottlenecks.

The confusion stems from the conflict between the Controlled Substances Act, which classifies marijuana as a Schedule I substance, and 38 state medical cannabis programs that issue patient identification cards. While TSA's May 2019 policy update permits hemp-derived CBD products containing less than 0.3% THC under the 2018 Farm Bill, no federal exception exists for state-authorized medical marijuana in any form, including oils, edibles, or flower.

Industry analysts noted that the reaffirmation creates operational risks for medical cannabis patients traveling between legal states, as local law enforcement response varies significantly by jurisdiction. At Los Angeles International, airport police have declined to cite passengers possessing under 28.5 grams since 2018, while Miami-Dade officers continue to enforce Florida's prohibition on non-resident medical cannabis possession, creating unpredictable enforcement outcomes for connecting passengers.

The policy clarification matters for the estimated 6.7 million registered medical cannabis patients nationwide, many of whom face difficult choices between accessing medication during travel or risking federal referral. Patient advocacy groups called for Congressional action to establish a federal medical cannabis travel exemption, though no legislation addressing the conflict has advanced in the 119th Congress as of May 2026.
