Marijuana in the Manufacturing Workplace

The requirement to maintain a safe workplace often clashes with state and local laws that protect the rights of individuals who use marijuana while off-duty, creating unique challenges for manufacturing employers.

Manufacturing employers still may prohibit the use of marijuana at work, as well as marijuana impairment at work. But marijuana drug testing is complicated and controversial because of the legal protections for off-duty marijuana use in some states and cities, the legal protections for medical marijuana users in many jurisdictions, and because there are no drug tests that can detect current marijuana impairment or very recent use of marijuana.

Federal Law

Manufacturers no longer should defend “zero tolerance” marijuana drug testing policies. Previously, employers could argue that marijuana still is illegal under federal law or that the employer is a federal contractor that must comply with the federal Drug-Free Workplace Act. The federal government has not enforced the law that makes marijuana illegal for some time, and it has permitted states to create and enforce their own laws with respect to medical and recreational marijuana.

Some courts have recognized that the federal government is allowing state governments to regulate marijuana and, therefore, courts are enforcing state marijuana laws despite marijuana’s illegal status at the federal level. Courts also have rejected arguments that federal contractors “must follow federal law” because the federal Drug-Free Workplace Act does not require drug testing and does not permit employers to regulate off-duty conduct.

State Laws

At present, 39 states and the District of Columbia have medical marijuana laws, while 22 states and the District of Columbia have recreational marijuana laws (Maryland’s law will take effect in July and others will be enacted in the coming months). Many of these laws provide employment protections to applicants and employees. The variations in the laws make it difficult for multi-state manufacturers to have consistent marijuana policies in all locations.

What It Means for Employers

Due to the recent trend in some states to protect off-duty use of marijuana, and even prohibiting pre-employment marijuana testing, many manufacturers are discontinuing pre-employment marijuana testing, especially in states where marijuana is legal. Applicants often are surprised to learn that a positive marijuana drug test will lead to withdrawal of the job offer. If the positive marijuana drug test result is due to medical use (and there are no general off-duty protections in the state), manufacturers must be familiar with the applicable law.

Some states prohibit discrimination against medical marijuana users, while other states may allow an employer to take an adverse employment action if the job is considered “safety-sensitive,” i.e., a job with dangerous duties, as defined by applicable state law.

In certain other states where discrimination is prohibited and the manufacturing employer has safety concerns, the employer should engage in the “individualized assessment” and “direct threat analysis” required under state laws that mirror the federal Americans With Disabilities Act. This process includes discussions with the applicant and the applicant’s physician to assess the safety risk.

Reasonable suspicion marijuana testing is permissible in most states because impairment at work never is permitted. In states where off-duty marijuana use is protected, manufacturers should rely on the impaired behaviors when taking disciplinary action, rather than rely solely on the positive marijuana drug test result (assuming that testing for marijuana is permitted). This is because marijuana stays in the human body for a long time, so the positive drug test result is not conclusive proof that the employee was impaired at work. Manufacturers also should make sure that supervisors and managers are trained to observe and document reasonable suspicion determinations properly, as these documented observations will be key evidence in a potential lawsuit.

To make matters even more complicated, CBD (cannabidiol), “low THC,” and hemp products are being marketed and sold everywhere since Congress legalized hemp (having no more than 0.3 percent THC, the psychoactive component of marijuana) in 2018. Separate from marijuana laws, the use of “low THC” or CBD products is allowed in a number of states, usually for medical purposes, which means that manufacturing employers should tread carefully when an applicant or employee claims to use CBD products for medical reasons. While many CBD and hemp products are marketed as having little or no THC, these statements may not be true, because the U.S. Food and Drug Administration does not yet regulate them. These products may cause positive drug test results for marijuana. There has been an increase in lawsuits where former employees claim that their positive marijuana drug test results allegedly were caused by CBD products.

While it appears that marijuana eventually will be legalized at the federal level, manufacturers must ensure they are complying with all applicable laws. Manufacturing employers should:

  • Review drug and alcohol policies for compliance with applicable drug testing and marijuana laws;
  • Remove marijuana from the drug testing panel in locations where testing for marijuana is prohibited and locations where off-duty use is protected and consider removing it in other locations where it may be an obstacle in the hiring process;
  • Train Human Resources employees and other managers to engage in the interactive process with employees who use medical marijuana (or medical CBD products); and
  • Train supervisors to make appropriate and timely “reasonable suspicion” determinations.

Mixed Results for Employers on Marijuana – Two Federal Courts Refuse to Find State Marijuana Laws Preempted by Federal Law

Two recent federal cases illustrate why employers – even federal contractors – must be cognizant of relevant state-law pronouncements regarding the use of marijuana (i.e., cannabis) by employees. While one case found in favor of the employer, and the other in favor of the employee, these decisions have emphasized that state law protections for users of medical marijuana are not preempted by federal laws such as the Drug-Free Workplace Act (DFWA). Employers must craft a thoughtful and considered approach to marijuana in the workplace, and in most cases should not take a zero-tolerance approach to marijuana.

Ninth Circuit Finds in Favor of Employer Who Discharged Employee for Positive Drug Test

In Carlson v. Charter Communication, LLC, the Ninth Circuit affirmed the dismissal of a lawsuit brought by an employee who alleged discrimination under the Montana Medical Marijuana Act (MMA) because he was discharged for testing positive for marijuana use. The plaintiff, a medical marijuana cardholder under Montana state law, tested positive for THC (a cannabinoid) after an accident in a company-owned vehicle. His employer, a federal contractor required to comply with the DFWA, terminated his employment because the positive test result violated its employment policy.

The District Court of Montana held that the employer was within its rights to discharge the plaintiff because (1) the DFWA preempts the MMA on the issue of whether a federal contractor can employ a medical marijuana user; and (2) the MMA does not provide employment protections to medical marijuana cardholders. Indeed, the MMA specifically states that employers are not required to accommodate the use of medical marijuana, and the Act does not permit a cause of action against an employer for wrongful discharge or discrimination. The Ninth Circuit rejected this rationale. Because the MMA does not prevent employers from prohibiting employees from using marijuana and does not permit employees for suing for discrimination or wrongful termination, the Ninth Circuit held that the MMA does not preclude federal contractors from complying with the DFWA and thus found no conflict.

The plaintiff asserted that the provisions of the MMA exempting employers from accommodating registered users and prohibiting such users from bringing wrongful discharge or discrimination lawsuits against employers are unconstitutional and sought certification of the question to the Montana Supreme Court. The Ninth Circuit rejected this request because, it determined, the Montana Supreme Court already decided the issue. The MMA and the specific sections challenged by the plaintiff appropriately balance Montana’s legitimate state interest in regulating access to a controlled substance while avoiding entanglement with federal law, which classifies the substance as illegal.

Plaintiff Wins Summary Judgment Against Employer That Rescinded Job Offer Due to Positive Test

If federal law does not preempt state law on the issue of marijuana, then in certain states – like Connecticut – employers will be more susceptible to discrimination claims from marijuana users. In Noffsinger v. SSC Niantic Operating Company, the District of Connecticut granted summary judgment to a plaintiff-employee of Bride Brook Nursing & Rehabilitation Center who used medical marijuana to treat post-traumatic stress disorder (“PTSD”) and whose offer was rescinded for testing positive for THC during a post-offer drug screen. Plaintiff filed a discrimination claim under the Connecticut Palliative Use of Marijuana Act (“PUMA”), which makes it illegal for an employer to refuse to hire a person or discharge, penalize, or threaten an employee “solely on the basis of such person’s or employee’s status as a qualifying patient or primary caregiver.”

We covered a previous decision in this case, in which the court held that PUMA is not preempted by the federal Controlled Substance Act (“CSA”), the Americans with Disabilities Act, or the Food, Drug & Cosmetic Act (“FDCA”). The decision was notable then for being the first federal decision to hold that the CSA does not preempt a state medical marijuana law’s anti-discrimination provision, a departure from a previous federal decision in New Mexico.

In this recent decision, the District Court again considered whether PUMA was preempted by federal law. In ruling for the Plaintiff, the court rejected Bride Brook’s argument that its practices fall within an exception to PUMA’s anti-discrimination provision because they are “required by federal law or required to obtain federal funding.” Bride Brook argued that in order to comply with DFWA, which requires federal contractors to make a good faith effort to maintain a drug-free workplace, it could not hire plaintiff because of her failed pre-employment drug-test. The court was not persuaded, concluding that the DFWA does not require drug testing, nor does it prohibit federal contractors from employing people who use illegal drugs outside the workplace. The court noted that simply because Bride Brook’s zero-tolerance policy went beyond the requirements of the DFWA does not mean that hiring the plaintiff would violate the Act.

The court also rejected Bride Brook’s argument that the federal False Claims Act (“FCA”) prohibits employers from hiring marijuana users because doing so would amount to defrauding the federal government. Because no federal law prohibits employers from hiring individuals who use medicinal marijuana outside of work, employers do not defraud the government by hiring those individuals.

Lastly, the court rejected the theory that PUMA only prohibits discrimination on the basis of one’s registered status and not the actual use of marijuana, as such a holding would undermine the very purpose for which the employee obtained the status.

What These Decisions Mean for Employers

These decisions are notable for the fact that the federal courts refused to find the state laws were preempted by federal law. Importantly, neither found that the DFWA preempts state law, which means that even federal contractors must be aware of and follow state law with respect to marijuana use by employees. Thus, in states in which employers may not discriminate against medical marijuana users – such as Connecticut – all employers must take care not to make adverse employment decisions based solely on off-duty marijuana use and, in certain states, must accommodate medical marijuana use. A majority of states and the District of Columbia now permit the use of medical marijuana; employers, including federal contractors, should be mindful of these statutes and consult with counsel to ensure their employment policies are compliant.
