TSA Cannabis Policy: What Happens When They Find Marijuana at Airport Security

Executive Summary

The Transportation Security Administration updated its cannabis screening policy in May 2026, clarifying that TSA officers focus on aviation security threats rather than actively searching for marijuana. While TSA does not specifically search for cannabis during passenger screening, officers who discover marijuana during routine security checks must refer the matter to law enforcement, creating a complex legal gray area for travelers. The policy change reflects the growing tension between federal prohibition under the Controlled Substances Act and state-level legalization in 38 states plus the District of Columbia. Travelers carrying cannabis products face potential federal prosecution under 21 U.S.C. § 812, even when flying between two states where marijuana is legal. The updated guidance affects approximately 2.9 million daily passengers across U.S. airports, with enforcement outcomes varying dramatically based on local law enforcement policies, departure airport location, and product type. Medical marijuana patients with state-issued cards receive no federal exemption, while hemp-derived CBD products containing less than 0.3% THC remain legal for air travel under the 2018 Farm Bill.

Why TSA Cannabis Policy Matters

TSA's cannabis screening approach directly impacts millions of medical patients, recreational users, and cannabis industry professionals who fly domestically each year. The agency screened over 1.06 billion passengers in 2025, and with 24 states allowing adult-use cannabis and 38 permitting medical marijuana, a substantial portion of air travelers now live in jurisdictions where cannabis is legal under state law. The economic stakes are significant. The U.S. cannabis industry generated $33.6 billion in sales during 2025, with interstate commerce remaining federally prohibited. Industry executives, cultivators, processors, and dispensary operators frequently travel by air carrying product samples, lab results, and business documentation that references Schedule I controlled substances. A single TSA referral can trigger DEA investigation, jeopardize state licenses, and expose businesses to asset forfeiture under 21 U.S.C. § 881. Medical patients face particularly acute dilemmas. Approximately 800,000 Americans hold valid medical marijuana cards, many for serious conditions including epilepsy, cancer, PTSD, and chronic pain. Patients traveling for medical treatment, family emergencies, or extended vacations must choose between going without medication or risking federal prosecution. Pediatric epilepsy patients using high-CBD strains like Charlotte's Web have documented seizure increases when forced to interrupt treatment during travel. The policy also creates operational confusion for airport law enforcement agencies. Some jurisdictions—including Los Angeles International Airport, Denver International Airport, and Seattle-Tacoma International Airport—have adopted de facto non-enforcement policies for personal-use quantities. Others, particularly in states without legalization, pursue aggressive prosecution. This patchwork enforcement means identical conduct results in vastly different legal consequences depending on departure city, creating what legal scholars call "airport jurisdiction roulette."

Background and History: From Zero Tolerance to Studied Ambiguity

TSA's cannabis policy has evolved from absolute prohibition to selective enforcement over two decades, mirroring broader shifts in American drug policy.

2001-2012: Post-9/11 Security Focus and Early Medical Marijuana Conflicts

The Transportation Security Administration was created in November 2001 following the September 11 attacks, with a singular mission: prevent weapons, explosives, and other security threats from entering aircraft. The Aviation and Transportation Security Act (Public Law 107-71) made no mention of drug enforcement, yet TSA inherited a law enforcement culture from its predecessor agencies. During this period, TSA maintained strict coordination with the Drug Enforcement Administration. Officers who discovered any quantity of marijuana during screening referred passengers to airport police without exception. California had legalized medical marijuana via Proposition 215 in 1996, creating the first major conflict between state cannabis programs and federal aviation security. Medical patients with valid recommendations faced arrest at San Francisco International Airport and Oakland International Airport despite compliance with state law. In 2005, the Supreme Court ruled in Gonzales v. Raich that federal prohibition applied even to medical marijuana grown and consumed entirely within California, establishing that the Controlled Substances Act preempted state legalization. This decision emboldened TSA to maintain zero-tolerance policies regardless of state law.

2012-2014: Colorado and Washington Legalization Force Policy Reconsideration

Colorado and Washington voters approved adult-use legalization in November 2012, with retail sales beginning in Colorado on January 1, 2014. Denver International Airport suddenly faced a practical impossibility: a substantial percentage of departing passengers were legal state cannabis consumers, many of whom might inadvertently carry residual amounts. TSA issued its first significant policy clarification in May 2013, stating that "TSA security officers do not search for marijuana or other drugs." The agency emphasized that screening procedures focus on "security and are designed to detect potential threats to aviation and passengers." However, the guidance maintained that officers who discovered marijuana during screening must refer the matter to law enforcement. Denver International Airport responded by installing cannabis amnesty boxes before security checkpoints, allowing passengers to dispose of products before screening. The boxes collected approximately 1,000 pounds of cannabis in their first year of operation.

2015-2018: Medical Marijuana Expansion and CBD Confusion

By 2017, 29 states had legalized medical marijuana, creating a national patchwork. TSA faced increasing questions about medical cannabis oil, tinctures, and CBD products. The agency's position remained unchanged: all marijuana products were prohibited under federal law regardless of medical status or state legalization. The 2018 Farm Bill, signed December 20, 2018, removed hemp (cannabis containing less than 0.3% THC) from Schedule I, legalizing hemp-derived CBD products. This created a new category of legal cannabis products for air travel, but also introduced enforcement challenges. TSA officers cannot distinguish hemp-derived CBD from marijuana-derived CBD through visual inspection, and most airports lack testing equipment.

2019-2021: Explicit Policy Updates and Enforcement Discretion

In May 2019, TSA updated its "What Can I Bring?" website to explicitly address medical marijuana. The guidance stated: "Marijuana and certain cannabis infused products, including some Cannabidiol (CBD) oil, remain illegal under federal law except for products that contain no more than 0.3 percent THC on a dry weight basis or that are approved by FDA." The update represented a subtle but significant shift. By acknowledging that TSA does not actively search for marijuana while maintaining referral requirements, the agency effectively delegated enforcement decisions to local airport police. In jurisdictions with non-enforcement policies, this meant de facto permission for personal-use quantities. Los Angeles International Airport adopted an explicit policy in September 2019 allowing passengers to travel with cannabis in amounts legal under California law (up to 28.5 grams of flower or 8 grams of concentrate). Airport police would not cite passengers for possession unless they exceeded state limits. Similar policies emerged at Las Vegas McCarran International Airport, Portland International Airport, and Boston Logan International Airport.

2022-2024: Rescheduling Debate and Policy Stasis

President Biden's October 2022 directive to review marijuana's Schedule I status created uncertainty about future TSA policy. The Department of Health and Human Services recommended rescheduling to Schedule III in August 2023, which would maintain criminal prohibition but acknowledge accepted medical use. TSA made no policy changes during this period, maintaining that marijuana remains federally prohibited regardless of ongoing rescheduling proceedings. The agency processed approximately 858 million passengers in 2023 and 1.02 billion in 2024, with no published data on marijuana-related law enforcement referrals.

May 2026: Updated Guidance and Continued Ambiguity

TSA's May 2026 policy update reiterated existing guidance with enhanced clarity. The agency emphasized that screening focuses on aviation security threats—explosives, weapons, and prohibited items that could endanger aircraft. Officers do not open bags or conduct searches specifically to find marijuana. However, the update maintained the referral requirement: when officers discover marijuana during routine screening, they must notify law enforcement. The guidance explicitly stated that TSA does not determine whether marijuana possession is legal under state law—that determination falls to airport police and local prosecutors. The update coincided with growing pressure from the cannabis industry, medical patient advocates, and congressional representatives from legalization states. Representative Earl Blumenauer of Oregon and Senator Ron Wyden of Oregon had introduced the Marijuana Revenue and Regulation Act in 2025, which included provisions to clarify TSA policy, but the legislation remained stalled in committee.

Key Players in TSA Cannabis Policy

Transportation Security Administration

TSA operates as a component of the Department of Homeland Security, employing approximately 60,000 personnel including 47,000 Transportation Security Officers who conduct passenger screening. Administrator David Pekoske, who has led the agency since 2017, has maintained that TSA's mission focuses on aviation security rather than drug enforcement. The agency's official position balances federal law compliance with operational pragmatism—officers are not trained as drug detection specialists and lack authority to make arrests.

Drug Enforcement Administration

The DEA maintains that marijuana remains a Schedule I controlled substance under 21 U.S.C. § 812, defined as having no accepted medical use and high potential for abuse. DEA Administrator Anne Milgram has stated that the agency prioritizes large-scale trafficking and organized crime over individual possession cases, but possession of any quantity technically violates federal law. The DEA has not issued specific guidance regarding airport cannabis enforcement, leaving prosecution decisions to U.S. Attorneys in each jurisdiction.

Airport Law Enforcement Agencies

Local police departments and airport authorities determine actual enforcement outcomes. The Los Angeles Airport Police Division, Denver Police Department Airport Bureau, and Massachusetts State Police at Logan International Airport have adopted policies treating personal-use cannabis possession as the lowest enforcement priority. Conversely, Dallas/Fort Worth International Airport Police and Hartsfield-Jackson Atlanta International Airport Police actively prosecute possession cases, reflecting state laws in Texas and Georgia where marijuana remains fully prohibited.

Cannabis Industry Trade Groups

The National Cannabis Industry Association, representing over 1,800 businesses, has advocated for explicit safe harbor provisions allowing industry professionals to transport product samples and documentation. The U.S. Cannabis Council has proposed TSA adopt quantity-based thresholds similar to alcohol regulations, allowing passengers to carry amounts equivalent to state possession limits. These proposals have not been adopted.

Medical Patient Advocacy Organizations

Americans for Safe Access, founded in 2002, represents medical marijuana patients and has documented cases of patients arrested at airports despite valid state medical cards. The organization has called for TSA to recognize state medical marijuana programs and allow patients to travel with physician-recommended amounts. The Epilepsy Foundation has specifically advocated for pediatric patients using CBD and THCA products for seizure control.

Congressional Representatives

The Congressional Cannabis Caucus, co-chaired by Representatives Earl Blumenauer, Barbara Lee, and Dave Joyce, has pressed TSA for clearer guidance. Senator Cory Booker of New Jersey introduced the Cannabis Administration and Opportunity Act in 2025, which would deschedule marijuana and require TSA to treat cannabis like alcohol. The legislation has not advanced to a floor vote.

Legal and Regulatory Framework

TSA cannabis policy operates within a complex web of federal statutes, agency regulations, and state laws that often directly conflict. The Controlled Substances Act, codified at 21 U.S.C. § 801 et seq., classifies marijuana as a Schedule I substance under 21 U.S.C. § 812(c). Schedule I drugs are defined as having high potential for abuse, no currently accepted medical use in treatment in the United States, and lack of accepted safety for use under medical supervision. Possession of any quantity violates 21 U.S.C. § 844, punishable by up to one year imprisonment and a minimum $1,000 fine for first offense. Transportation of marijuana across state lines constitutes drug trafficking under 21 U.S.C. § 841, even between two states where marijuana is legal. A passenger flying from California to Colorado with cannabis technically commits a federal felony punishable by up to five years imprisonment for quantities under 50 kilograms. Federal prosecutors rarely pursue such cases for personal-use amounts, but the legal exposure exists. The Aviation and Transportation Security Act (49 U.S.C. § 114) established TSA's authority and mission. The statute directs TSA to "provide for the screening of all passengers and property" to prevent weapons, explosives, and other threats from being transported aboard aircraft. Notably, the statute does not mention drug enforcement or grant TSA officers arrest authority. TSA officers are not law enforcement agents under federal law. They cannot make arrests, issue citations, or conduct criminal investigations. When officers discover marijuana, they must refer the matter to airport police or other law enforcement agencies with arrest authority. This jurisdictional limitation creates the enforcement gap that allows local non-prosecution policies to function. The 2018 Farm Bill (Agriculture Improvement Act of 2018, Public Law 115-334) amended the Controlled Substances Act to exclude hemp, defined as cannabis containing not more than 0.3% delta-9 THC on a dry weight basis. Hemp-derived CBD products are legal for air travel if they meet this threshold. However, marijuana-derived CBD remains Schedule I regardless of THC content, and TSA officers cannot distinguish between the two without laboratory testing. State laws create the patchwork that generates enforcement confusion. California allows possession of up to 28.5 grams of flower or 8 grams of concentrate for adults 21 and older (Health and Safety Code § 11357). New York permits up to 3 ounces of flower (Cannabis Law § 222.05). Texas criminalizes any amount, with possession of under 2 ounces classified as a Class B misdemeanor punishable by up to 180 days in jail (Health and Safety Code § 481.121). Medical marijuana programs add another layer. Thirty-eight states have legalized medical cannabis, each with different possession limits, qualifying conditions, and reciprocity provisions. A Florida medical marijuana patient with a valid card can possess up to a 70-day supply as determined by their physician (Florida Statutes § 381.986), but that card provides no protection under federal law or in states without reciprocity. The Rohrabacher-Farr Amendment (now Rohrabacher-Blumenauer Amendment), included in annual appropriations bills since 2014, prohibits the Department of Justice from using funds to prevent states from implementing medical marijuana laws. However, this protection applies only to state-authorized medical marijuana activities and does not bind TSA, which operates under the Department of Homeland Security.

State-by-State Enforcement Landscape at Major Airports

Identical TSA discoveries result in dramatically different outcomes depending on airport location, creating a de facto federalism experiment in cannabis enforcement.

California

Los Angeles International Airport, San Francisco International Airport, and other California airports operate under explicit non-enforcement policies. LAX policy states that airport police do not cite passengers for marijuana possession in amounts compliant with California law. San Francisco International Airport adopted similar guidance in 2018. However, passengers still face federal prosecution risk if referred to FBI or DEA, and destination state laws apply upon arrival. Possession limits: 28.5 grams flower, 8 grams concentrate for adults 21+.

Colorado

Denver International Airport allows possession in amounts legal under Colorado law (1 ounce flower for adults 21+) but prohibits consumption on airport property. Cannabis amnesty boxes are located before security checkpoints. Denver Airport Police treat personal-use possession as lowest priority, typically issuing warnings rather than citations. Colorado Springs Airport, located in a jurisdiction that banned retail sales, maintains stricter enforcement.

Nevada

Las Vegas Harry Reid International Airport (formerly McCarran) adopted a non-enforcement policy in September 2019, allowing possession up to Nevada's legal limit (1 ounce flower, 3.5 grams concentrate). Airport signs inform passengers that while possession is legal in Nevada, marijuana remains federally prohibited and illegal in many destination states. Clark County regulations govern enforcement.

Oregon

Portland International Airport policy states that airport police do not enforce marijuana possession laws for amounts legal under Oregon law (2 ounces flower for adults 21+). However, TSA referrals still occur, and passengers traveling to states without legalization face prosecution upon arrival. Oregon State Police maintain jurisdiction at the airport.

Washington

Seattle-Tacoma International Airport allows possession up to Washington's legal limit (1 ounce flower). Port of Seattle Police treat personal-use possession as a civil infraction rather than criminal offense, consistent with statewide decriminalization. However, international flights departing SeaTac face enhanced scrutiny due to customs enforcement.

Massachusetts

Boston Logan International Airport falls under Massachusetts State Police jurisdiction. While Massachusetts allows possession of up to 1 ounce for adults 21+, State Police maintain discretion to enforce federal law. Enforcement has been inconsistent, with some passengers warned and released while others face federal charges depending on quantity and officer judgment.

New York

New York legalized adult-use cannabis in March 2021, allowing possession up to 3 ounces. However, John F. Kennedy International Airport, LaGuardia Airport, and Newark Liberty International Airport (across the river in New Jersey) maintain stricter enforcement due to Port Authority Police jurisdiction. Port Authority has not adopted explicit non-enforcement policies, resulting in continued arrests for marijuana possession.

Illinois

Chicago O'Hare International Airport and Chicago Midway International Airport operate under Chicago Police Department jurisdiction. Illinois allows possession of up to 30 grams (approximately 1 ounce) for residents and 15 grams for non-residents. Chicago Police generally do not arrest for personal-use amounts, but TSA referrals still occur and federal prosecution remains possible.

Michigan

Detroit Metropolitan Wayne County Airport allows possession up to Michigan's legal limit (2.5 ounces flower). Wayne County Airport Authority Police have adopted a de facto non-enforcement approach for personal-use quantities, focusing resources on trafficking and other crimes.

Arizona

Phoenix Sky Harbor International Airport falls under Phoenix Police Department jurisdiction. Arizona legalized adult-use cannabis in November 2020, allowing possession of up to 1 ounce. Phoenix Police treat personal-use possession as a low priority, but enforcement varies by officer and circumstances.

Florida

Florida has medical marijuana only, with no adult-use legalization. Miami International Airport, Orlando International Airport, and Tampa International Airport actively enforce prohibition. Medical marijuana patients with valid Florida cards may avoid state charges but still face federal prosecution risk. Possession without a medical card remains a criminal offense under Florida Statutes § 893.13.

Texas

Dallas/Fort Worth International Airport and George Bush Intercontinental Airport in Houston maintain strict enforcement. Texas criminalizes all marijuana possession, and airport police actively prosecute cases referred by TSA. Even small amounts result in criminal charges, with possession under 2 ounces classified as a Class B misdemeanor punishable by up to 180 days in jail and a $2,000 fine.

Georgia

Hartsfield-Jackson Atlanta International Airport, the world's busiest airport by passenger traffic, enforces Georgia's prohibition strictly. Possession of any amount is a misdemeanor under O.C.G.A. § 16-13-30, punishable by up to one year in jail. Atlanta Police Department Airport Precinct arrests passengers referred by TSA, with cases prosecuted in Fulton County courts.

Market and Business Implications

TSA's ambiguous cannabis policy creates operational challenges and legal risks for the $33.6 billion U.S. cannabis industry, constraining interstate commerce and complicating business travel. Multi-state operators face particular difficulties. Companies like Curaleaf, Trulieve, Green Thumb Industries, and Cresco Labs operate dispensaries and cultivation facilities in multiple states but cannot transport products across state lines due to federal prohibition. Executives traveling between facilities must rely on commercial air travel without carrying product samples, forcing each state operation to maintain independent genetics, testing protocols, and quality control systems. The inability to transport samples for testing creates quality control gaps. A cultivation facility in Massachusetts cannot send flower samples to a preferred testing laboratory in California for terpene analysis or contaminant screening. Each state requires in-state testing, fragmenting the industry and preventing economies of scale in laboratory services. Cannabis industry conferences and trade shows generate additional complications. Events like MJBizCon in Las Vegas, the Benzinga Cannabis Capital Conference, and regional trade shows attract thousands of industry professionals who want to display products, conduct sensory evaluations, and facilitate wholesale negotiations. Attendees from legalization states cannot legally transport products to conference venues, limiting the utility of trade shows compared to other industries. Investment and capital flows suffer from travel restrictions. Institutional investors conducting due diligence on cannabis companies cannot easily inspect cultivation facilities, processing operations, and retail locations across multiple states while carrying documentation that references Schedule I substances. Private equity firms and family offices have cited TSA policy as a friction point in cannabis investment decisions. The hemp and CBD industry operates under different rules following the 2018 Farm Bill, but enforcement remains inconsistent. Companies producing hemp-derived CBD products can legally transport samples and finished goods by air, but TSA officers often cannot distinguish hemp from marijuana without laboratory testing. This has resulted in seizures of legal hemp products, particularly CBD isolate and distillate that visually resemble marijuana concentrates. Ancillary businesses—including software providers, packaging companies, and consulting firms—face fewer restrictions but still encounter complications. A cannabis point-of-sale software company with clients in multiple states can travel freely, but employees carrying marketing materials that depict marijuana products have reported enhanced TSA scrutiny and secondary screening. The policy also affects medical marijuana research. Academic institutions and pharmaceutical companies conducting FDA-approved clinical trials on cannabis compounds face logistical barriers transporting research materials between facilities. While DEA licenses allow some interstate transport of research cannabis, air travel with Schedule I substances requires extensive documentation and advance coordination with airlines and TSA. Employment implications extend beyond the cannabis industry. Approximately 428,000 Americans work in legal cannabis businesses as of 2025, according to industry data. These workers face potential federal prosecution for conduct that is legal under state law and part of their licensed employment. A budtender in Colorado who flies home to visit family in California with a small amount of cannabis for personal use commits a federal felony, despite working in a state-licensed industry. The policy creates competitive advantages for companies in states with multiple major airports and non-enforcement policies. California-based cannabis companies benefit from LAX, SFO, and other airports with permissive policies, while companies in Texas or Georgia face stricter constraints on employee travel and business operations. Insurance and risk management costs increase due to policy uncertainty. Cannabis companies pay premium rates for directors and officers liability insurance, in part because executives face potential federal prosecution for activities including air travel with cannabis. Employment practices liability insurance similarly costs more due to the risk that employees could be arrested for work-related travel.

What Experts and Stakeholders Say

Cannabis policy experts, law enforcement officials, and industry leaders express divergent views on TSA's approach, with broad consensus that federal prohibition creates untenable contradictions. According to the National Organization for the Reform of Marijuana Laws, TSA's policy represents a pragmatic accommodation to state legalization within the constraints of federal law. NORML Deputy Director Paul Armentano has stated that the agency's focus on aviation security rather than drug enforcement reflects appropriate prioritization, but he argues that only federal descheduling can resolve the underlying legal conflicts. The National Cannabis Industry Association has called for explicit safe harbor provisions allowing licensed cannabis businesses to transport samples and documentation. NCIA spokesperson Morgan Fox has emphasized that the current policy forces companies to operate inefficiently, preventing quality control best practices and constraining industry professionalization. Law enforcement perspectives vary by jurisdiction. Los Angeles Airport Police Chief David Maggard has explained that his department's non-enforcement policy reflects California law and efficient resource allocation. According to Maggard, airport police focus on serious crimes including human trafficking, weapons violations, and organized theft rings rather than personal marijuana possession. Conversely, law enforcement in prohibition states maintain stricter approaches. The Georgia Bureau of Investigation has stated that marijuana possession remains illegal under state and federal law, and airport arrests serve important deterrent functions. GBI officials argue that permissive policies in other states do not obligate Georgia to decline prosecution. Medical marijuana patient advocates emphasize the policy's impact on vulnerable populations. Americans for Safe Access has documented cases of epilepsy patients arrested at airports while traveling with physician-recommended CBD and THCA products. According to the organization, TSA policy forces patients to choose between medication access and travel, violating principles of medical necessity and patient autonomy. Aviation industry representatives generally support TSA's security-focused approach. Airlines for America, the trade association representing major U.S. carriers, has stated that airlines comply with federal law and prohibit marijuana on flights regardless of state legalization. The association has not advocated for policy changes, deferring to federal drug enforcement agencies. Legal scholars note the constitutional federalism tensions. Professor Robert Mikos of Vanderbilt Law School, an expert on marijuana federalism, has written that TSA policy illustrates the practical limits of federal prohibition in an era of state legalization. According to Mikos, the federal government lacks resources to enforce prohibition without state cooperation, creating de facto legalization in jurisdictions that decline to prosecute. Civil liberties organizations have raised concerns about selective enforcement and racial disparities. The American Civil Liberties Union has noted that Black travelers are more likely to face enhanced TSA screening and law enforcement referral than white travelers, even when carrying identical amounts of cannabis. The ACLU has called for data collection on TSA marijuana referrals by race to assess potential discrimination. The Drug Policy Alliance, which advocates for drug decriminalization, argues that TSA should adopt explicit non-enforcement policies rather than delegating decisions to local police. According to the organization, the current approach creates a confusing patchwork that exposes travelers to arbitrary enforcement based on airport location and individual officer discretion. Industry analysts project that TSA policy will remain unchanged until federal rescheduling or descheduling occurs. Cowen investment analyst Vivien Azer has stated that the cannabis industry has adapted to current restrictions by developing state-specific supply chains, and that policy clarity would reduce costs but is not essential for continued growth.

What's Next: Policy Scenarios and Decision Points

TSA cannabis policy will likely remain in its current state of studied ambiguity until federal marijuana scheduling changes, with several key decision points on the horizon. The most significant near-term catalyst is the DEA's ongoing rescheduling proceeding. Following HHS's August 2023 recommendation to move marijuana to Schedule III, DEA published a Notice of Proposed Rulemaking in May 2024, initiating a formal process that includes public comment and administrative hearings. If DEA reschedules marijuana to Schedule III, it would remain a controlled substance subject to criminal penalties, but the change could prompt TSA to update guidance acknowledging accepted medical use. Schedule III status would not legalize marijuana or authorize TSA to permit cannabis on flights. However, it could create political pressure for more permissive policies, particularly for medical marijuana patients. The rescheduling process faces legal challenges and could extend into 2027 or beyond before final implementation. Congressional legislation represents another potential catalyst. The Cannabis Administration and Opportunity Act, introduced by Senator Cory Booker and Senate Majority Leader Chuck Schumer, would deschedule marijuana entirely and require federal agencies to treat cannabis like alcohol. The bill includes specific provisions directing TSA to allow passengers to carry cannabis in amounts compliant with state law. However, the legislation lacks sufficient Republican support to overcome a Senate filibuster, and passage appears unlikely in the current Congress. The SAFE Banking Act, which would protect financial institutions serving cannabis businesses, has passed the House multiple times but stalled in the Senate. While SAFE Banking does not directly address TSA policy, its passage would signal growing congressional support for cannabis reform and could encourage administrative agencies to adopt more permissive interpretations of existing law. State-level developments will continue to shape enforcement landscape. Florida voters will decide on adult-use legalization in November 2026, and if approved, major airports in Miami, Orlando, and Tampa would likely adopt non-enforcement policies similar to other legalization states. Ohio began adult-use sales in August 2024, and Cleveland Hopkins International Airport and John Glenn Columbus International Airport are developing enforcement guidelines. Industry pressure for policy clarity will intensify as the cannabis market grows. Multi-state operators are exploring legal challenges to federal prohibition, and a successful lawsuit could force TSA to revise policies. However, federal courts have consistently upheld the Controlled Substances Act's constitutionality, making judicial relief unlikely without Supreme Court intervention. Technological developments may influence enforcement. Some airports are testing advanced imaging technology that can identify organic materials including cannabis with greater precision. Enhanced detection capabilities could increase referral rates, or alternatively, could allow TSA to distinguish between personal-use amounts and trafficking quantities, enabling more nuanced enforcement. International travel considerations will become more prominent as Canada, Mexico, and other countries maintain legalization. Passengers traveling from U.S. airports to international destinations face customs enforcement in addition to TSA screening, and cannabis possession can result in entry denial, criminal prosecution under foreign law, and travel bans. TSA may need to develop specific guidance for international departures to address these risks. The calendar of upcoming decision points includes DEA's final rescheduling decision (expected late 2026 or early 2027), the 2026 midterm elections (which could shift congressional composition and cannabis reform prospects), and ongoing state ballot initiatives in Nebraska, South Dakota, and Arkansas for November 2026. Industry observers anticipate that TSA will maintain its current policy—not actively searching for marijuana but referring discoveries to law enforcement—until federal law changes. This approach allows the agency to comply with the Controlled Substances Act while accommodating state legalization through local enforcement discretion. Absent congressional action or DEA rescheduling, the patchwork of airport-specific policies will persist, requiring travelers to research local enforcement practices before flying with cannabis.
