Medical Marijuana Use Protected from Adverse Action

April 2, 2025

A recent court decision in Pennsylvania offers clarification that employers cannot take adverse action for marijuana use against individuals who possess medical marijuana cards, at least under Pennsylvania’s Medical Marijuana Act.


In this decision, an individual received a conditional job offer for a non-safety sensitive position, contingent on a drug test. The individual disclosed his state-certified use of medical marijuana to treat anxiety, depression and ADHD, assuring the employer that it wouldn’t affect job performance or safety. After a positive test for marijuana, the employer rescinded the offer, citing safety concerns. The individual sued the employer under the Pennsylvania Medical Marijuana Act (“MMA”) and disability discrimination under the Pennsylvania Human Relations Act (“PHRA”).


The Court allowed the individual’s claim under the MMA to proceed, potentially creating substantial precedent for tolerance of individual medical marijuana use in non-safety sensitive positions. The Court specifically noted that MMA protects individuals not just from discrimination based on card holder status, but also for adverse actions based solely on lawful medical marijuana use. The Court otherwise dismissed the individual’s claims under the PHRA because the PHRA does not require employers to accommodate medical marijuana use, even if it is prescribed for a legitimate medical condition.


While a Pennsylvania decision, this decision potentially has rippling implications that will affect Massachusetts employers and employers in states where medical marijuana use is allowed under state law, which is allowed in some manner in 44 states.


Employer Takeaways

  1. Understand State-Specific Protections: Laws regarding medical marijuana use differ widely across states. In some areas, cardholder status is protected, while in others, it is not. Employers operating in multiple states must ensure their hiring and accommodation practices comply with the relevant laws in each state.
  2. Base Safety Concerns on Job-Specific Evidence: General or speculative safety concerns are insufficient, particularly in states with strict employee protections. Safety risks cited should be specific, evidence-based, and directly related to the essential functions of the job.
  3. Review Drug Testing and Accommodation Policies: Update your policies to reflect current state laws and clarify how your organization manages disclosures of medical marijuana use, especially during the hiring process.



If you have any queries regarding drug testing or other workplace accommodations following this ruling, it is prudent to contact legal counsel.

On June 27, 2025, the U.S. Supreme Court ruled in Trump v. CASA that federal district courts cannot block executive orders for the entire country. The Court held that such broad injunctions exceed the authority Congress granted under the Judiciary Act of 1789. Courts may now only stop enforcement for the parties in the case—not for everyone else. What Happened in the Case President Trump issued Executive Order 14160 in early 2025. It denies birthright citizenship to children born in the U.S. if neither parent is a citizen or lawful permanent resident. Multiple lawsuits followed. Three federal courts blocked the order nationwide. The Supreme Court disagreed. It sent the case back and told the lower courts to revise the injunctions to cover only the named plaintiffs. The Court did not decide whether the order itself violates the Constitution. It ruled only on how far a court’s injunction can reach. Why It Matters to Employers The ruling affects how quickly and widely federal courts can stop controversial policies, especially during fast-changing political cycles. Employers have often relied on national injunctions to pause new mandates on wages, workplace safety, pay transparency, and non-compete agreements. This decision limits that option. The Court said nothing about injunctions under the Administrative Procedure Act, which governs agency rules. But the opinion raises doubts about whether even those can continue on a nationwide scale. Justice Kavanaugh suggested they might, but the Court left that question for another day. What This Means for You No nationwide protection unless you sue If your business is not part of the case, you likely cannot rely on someone else’s win. You must litigate directly to get relief. Rules may take effect in one state and not another A federal court in Texas may block a rule, while a court in New York upholds it. National companies may face conflicting rules and inconsistent enforcement. Trade groups cannot shield you Even if your industry association wins an injunction, it may apply only to their members or to the parties named in the lawsuit. Older rulings may now shrink Past national injunctions—on vaccine mandates, non-compete bans, overtime rules, or joint-employer standards—could be challenged or narrowed based on this ruling. More class actions are likely Some plaintiffs may now push for class certification to restore broader relief. Employers could face more complex litigation as a result. Next Steps for Employers Identify any current or past rules your business has relied on that are being blocked nationwide. Confirm whether you were covered by name or just assumed you were protected. Reassess your risk exposure for pending federal actions under OSHA, the EEOC, the DOL, or the NLRB. Monitor APA-based injunctions to see whether courts continue to grant broad relief under that statute. Consider joining strategic litigation early if new executive orders or agency rules would harm your operations. You cannot assume another company’s lawsuit will protect you. The Court narrowed that path. To block a federal mandate, you may now need to act alone—or join the fight directly. Michael P.
