Cannabis and Your Job: What Minnesota Federal Employees, Military Members, and Government Contractors Need to Know in 2026

Minnesota legalized adult-use cannabis in 2023, and the state's new employment protections bar most private-sector employers from disciplining workers for off-duty cannabis use. But if you work for the federal government, hold a security clearance, serve in the military, or work for a company with a federal contract, state law provides you no protection at all. Federal law governs your job, and federal law still treats cannabis as a Schedule I controlled substance.

Here is what every Minnesota federal employee, government contractor, military service member, and security clearance holder needs to understand before buying cannabis at a licensed dispensary.

The Core Rule: Federal Law Preempts State Law

Minnesota Statutes section 342.33 prohibits most employers from disciplining employees for off-duty cannabis consumption. It is one of the strongest employment protection clauses of any state cannabis law in the country.

That protection does not apply to you if:

• You are a federal employee
• You work for a federal contractor and the contract is subject to the Drug-Free Workplace Act
• You are a member of the U.S. military (active duty, reserve, or National Guard on federal orders)
• Your job is classified as safety-sensitive under federal regulations (aviation, transportation, nuclear, etc.)
• Your employer requires a security clearance as a condition of employment

For all of these workers, the answer is simple and unchanged by Minnesota law: using cannabis -- even legally purchased at a licensed Minnesota dispensary, even on your day off -- can cost you your job, your clearance, or both.

Federal Employees

The federal workforce in Minnesota is substantial. The Twin Cities metro is home to major federal agency operations: the IRS Submission Processing Center in Andover, the Social Security Administration regional office, the Department of Veterans Affairs medical centers in Minneapolis and St. Cloud, the Army Corps of Engineers, the FBI field office, U.S. Customs and Border Protection at MSP Airport, and dozens of smaller agencies.

All federal employees are subject to the Drug-Free Workplace Act of 1988 (5 U.S.C. 7301), which prohibits federal employees from using, possessing, or distributing controlled substances on or off duty. Cannabis is a Schedule I controlled substance under the Controlled Substances Act. The fact that Minnesota has legalized it does not change federal law.

Federal agencies conduct both random and for-cause drug testing. A positive cannabis test for a federal employee can result in mandatory referral to a counseling program, suspension, or termination -- depending on the agency and the position. Employees in safety-sensitive or security-clearance positions face the most severe consequences.

The Biden administration issued guidance in 2021 clarifying that prior cannabis use alone should not automatically disqualify federal job applicants, but ongoing or current use remains prohibited for active federal employees.

Federal Contractors

Minnesota is home to a large defense and government contracting sector. Companies like Lockheed Martin (Eagan), Honeywell (Plymouth), General Dynamics (Bloomington), Raytheon (various sites), and dozens of smaller federal contractors employ tens of thousands of Minnesota workers.

Under the Drug-Free Workplace Act, federal contractors receiving federal contracts valued at $100,000 or more must maintain a drug-free workplace policy and inform employees that cannabis use is prohibited as a condition of the contract. Failure to maintain this policy can result in the contractor losing its federal contracts.

Practically, this means many federal contractors drug test employees in safety-sensitive roles, and a positive cannabis test -- even for legal off-duty use -- can lead to termination. Minnesota's employment protection law explicitly carves out employees whose jobs are governed by federal contract requirements.

If you are unsure whether your employer's federal contracts subject you to these requirements, ask your HR department or legal counsel before using cannabis. The stakes are your job and your employer's contracts.

Security Clearances

Cannabis use is one of the most common reasons for security clearance denial or revocation. The federal government adjudicates clearances under the 13 Adjudicative Guidelines, and Guideline H (Drug Involvement) directly addresses cannabis.

The core concern is not a single use -- it is pattern use, use that continues after being told it is prohibited, or use that suggests poor judgment or susceptibility to coercion. Key points:

• Past use before applying: Disclosed prior cannabis use is generally not disqualifying for most clearance levels if it was not recent and there is no pattern. Honesty matters -- lying about past use is often more damaging than the use itself.
• Current use in a legal state: Using cannabis after applying for or holding a clearance is a significant adjudicative concern. The fact that you used it legally in Minnesota does not matter -- you are using a substance that remains illegal under federal law, and clearance adjudicators evaluate this as a loyalty and judgment issue.
• Continued use after being told to stop: If a supervisor, HR, or security officer tells you that cannabis use is prohibited in your position and you continue using it, this is among the most disqualifying facts for a clearance renewal or upgrade.
• TS/SCI and above: Higher-level clearances receive more scrutiny. A polygraph may ask about cannabis use. Falsification is treated as fraud.

The Office of the Director of National Intelligence (ODNI) Adjudicative Guidelines do not include a bright-line rule that any cannabis use permanently disqualifies an applicant. Adjudicators weigh recency, frequency, context, and mitigating factors. But for most active clearance holders, the safest answer is zero use.

Military Members: A Harder Line

If you are on active duty, in the Reserves, or in the Minnesota National Guard activated under federal orders, Minnesota's cannabis law offers you nothing. The Uniform Code of Military Justice (UCMJ) Article 112a prohibits wrongful use of controlled substances, and cannabis is a controlled substance under federal law regardless of state law.

Military members who test positive for THC face non-judicial punishment (Article 15 proceedings), court-martial in serious cases, separation from service, and loss of veteran's benefits in some circumstances. There is no exception for state-legal cannabis use.

One additional concern: hemp-derived products including CBD oils, gummies, and beverages marketed as THC-free can cause positive drug tests if they contain trace amounts of delta-9 THC. The military explicitly warns members against consuming hemp products because of this risk. THC threshold for military drug testing is 15 ng/mL -- lower than many civilian screening levels -- and hemp contamination is a real risk even with products claiming to be below 0.3 percent THC.

Minnesota National Guard Members on State Orders

When Minnesota National Guard members are serving under state orders (not federal orders), they are subject to Minnesota state law rather than federal UCMJ. The Minnesota Department of Military Affairs has its own policies regarding cannabis. As of 2026, the Minnesota National Guard's drug testing policy prohibits cannabis use consistent with its federal mission requirements, even when members are on state orders. Guard members should consult their chain of command before using cannabis at any time.

Safety-Sensitive Workers Under Federal Regulations

Even outside of federal employment and contracting, certain industries are regulated by federal agencies with their own drug testing mandates:

• Transportation: The Department of Transportation (DOT) mandates drug testing for commercial motor vehicle operators (CDL holders), airline employees, rail workers, and pipeline workers. A DOT-regulated positive cannabis test results in removal from safety-sensitive duties, mandatory SAP (Substance Abuse Professional) evaluation, and return-to-duty requirements. Minnesota's employment protection law explicitly excludes DOT-regulated workers.
• Aviation: FAA medical certification requires disclosure of any substance use. Cannabis use is grounds for denial of a medical certificate, and falsification on FAA forms is a federal crime.
• Nuclear: Workers at nuclear facilities are tested under NRC regulations. Same federal preemption applies.
• Maritime: Coast Guard-regulated maritime workers face federal testing requirements.

Private Sector Employees with Federal Contract Roles

Even if your employer is a private company and you are not personally on a federal contract, your specific role may be subject to testing requirements. Defense contractors often apply drug-free workplace policies company-wide to avoid contract compliance complications. Before using cannabis, verify whether your specific role -- not just your employer -- is covered by federal contract drug testing requirements.

What Minnesota Law Does Protect (For Private-Sector Workers)

If you do not work for the federal government, do not hold a clearance, and are not in a federally regulated safety-sensitive role, Minnesota Statutes section 342.33 provides meaningful protection. Employers cannot:

• Refuse to hire someone based solely on a positive cannabis test in a pre-employment screen (for non-safety-sensitive roles)
• Discipline or terminate an employee solely for off-duty cannabis use
• Require disclosure of prior lawful cannabis use as a condition of employment

Exceptions exist for safety-sensitive positions even in the private sector -- jobs that involve operating heavy machinery, driving company vehicles, working at heights, or similar hazards may still conduct testing under Minnesota law's carve-outs.

Practical Advice for Affected Workers

If any of the above federal or quasi-federal rules apply to you:

1. Do not use cannabis, including CBD products. The safest path for federal employees, clearance holders, and military members is zero cannabis and zero hemp product consumption. The cross-contamination risk from hemp is real.
2. Read your employment contract and policies. Federal contractor employees should read their drug-free workplace policy and understand exactly which roles are subject to testing.
3. Disclose accurately. If you have used cannabis in the past and are applying for a federal position or clearance, consult an attorney about how to accurately disclose your history. Lying is almost always worse than the underlying use.
4. Monitor policy changes. Federal cannabis policy is evolving. The DEA's proposed rescheduling of cannabis from Schedule I to Schedule III has been in administrative review since 2024. If rescheduling is finalized, federal drug testing policies may change. Watch for updates at dea.gov.
