Cannabis Employment Protections in Minnesota

Last verified: March 2026

Overview: Strong Protections with Clear Exceptions

Minnesota's cannabis legalization law (HF 100) established some of the strongest employment protections for cannabis users in the country. The law fundamentally changed the relationship between employers and employees regarding cannabis use, while preserving employers' rights to maintain a safe workplace.

The key changes revolve around two statutes: the Drug and Alcohol Testing in the Workplace Act (DATWA) at §181.950 and the Lawful Consumable Products Act.

What Changed Under HF 100

Cannabis Removed from DATWA Definition of "Drug"

HF 100 amended Minnesota Statutes §181.950 to remove cannabis from the definition of "drug" under the Drug and Alcohol Testing in the Workplace Act. This single change has far-reaching implications:

• Employers can no longer include cannabis in pre-employment drug screening panels for most positions
• A positive cannabis test alone is no longer grounds for refusing to hire a job applicant
• Cannabis use discovered through testing cannot be the sole basis for adverse employment action

HF 100 amends the Drug and Alcohol Testing in the Workplace Act (DATWA) to remove cannabis from the definition of "drug," prohibiting most employers from requiring pre-employment cannabis testing.

Lawful Consumable Products Act Now Includes Cannabis

Minnesota's Lawful Consumable Products Act was expanded to include cannabis. This means employers generally cannot discipline or terminate employees for using lawful consumable products (including cannabis) during non-working hours and off the employer's premises.

First Positive Test: Counseling Required

If an employer does conduct cannabis testing (where permitted) and an employee tests positive for the first time, the employer must:

1. Offer the employee access to counseling or a rehabilitation program before taking any termination action
2. Give the employee a reasonable opportunity to participate in the program
3. Only after the employee declines counseling/rehabilitation, or fails to complete it, may the employer proceed with termination

This "counseling first" requirement applies on the first positive test only. Subsequent positive tests are handled according to the employer's policy.

Seven Exempt Categories

Minnesota's employment protections do not apply to the following categories. Employers in these areas may continue to test for cannabis and take adverse action based on positive results:

Key point: The definition of "safety-sensitive" is determined by the employer but must be reasonable and documented. Employers cannot simply label all positions as safety-sensitive to circumvent the law. If challenged, the designation must be defensible based on actual job duties and risks.

Medical Patient Protections

Registered medical cannabis patients enjoy additional employment protections beyond the standard HF 100 provisions:

• Minnesota Statutes §152.32 provides specific anti-discrimination protections for medical cannabis patients
• Employers cannot discriminate against an employee solely based on their status as a registered medical cannabis patient
• Medical patients may have stronger grounds to challenge adverse employment actions related to cannabis use
• These protections pre-date HF 100 and layer on top of the newer recreational protections

What Employers Can Still Do

Despite the new protections, employers retain significant rights:

• Prohibit impairment at work. No employee may be under the influence of cannabis during work hours, regardless of whether they have a medical card.
• Maintain workplace policies. Employers can maintain and enforce cannabis-free workplace policies that apply to work hours and premises.
• Test for cause. Employers may require cannabis testing based on reasonable suspicion of impairment at work (observed behavior, accidents, safety concerns).
• Test exempt positions. Employers may test all seven exempt categories, including pre-employment testing.
• Discipline for on-the-job impairment. An employee who is impaired at work faces the same consequences as being drunk on the job.

Federal Considerations

Minnesota's employment protections operate only under state law. Federal law still classifies cannabis as a Schedule I controlled substance:

• Federal DOT regulations still require cannabis testing for CDL holders, airline pilots, train operators, pipeline workers, and other safety-sensitive transportation positions
• Federal contractors subject to the Drug-Free Workplace Act may still require testing
• Federal employees are subject to federal drug testing requirements regardless of state law
• Employees working on federal installations in Minnesota (military bases, VA facilities) are subject to federal rules

Practical Guidance for Employees

• Know your position category. Determine whether your job falls into one of the seven exempt categories before relying on employment protections.
• Review your employer's policy. Even with legal protections, understanding your employer's specific cannabis policy helps you make informed decisions.
• Never be impaired at work. No protection covers impairment during work hours. This is the bright line.
• Consider medical registration. The additional protections under §152.32 may be valuable in your specific employment situation.
• Document everything. If you face adverse action you believe violates HF 100's employment protections, document the timeline and circumstances.
