Employer Liability Under State Medical Marijuana Laws

Across the country, employers in states allowing medical marijuana use have been grappling with whether these statutes impact employer policies concerning drug testing and maintaining a drug-free workplace.  Though the statutes allow for marijuana use for medical purposes (and some for recreational purposes), these statutes do not consistently address the impact of legal medical marijuana on employers, if at all.  And the number of states enacting such legislation is continuing to grow.

Since 1996, 20 states[1] and the District of Columbia have enacted some form of legislation that allows for the non-criminal use of marijuana for medical purposes.  In fact, in the last three years, eight states have passed medical marijuana laws – and Illinois became the 21st jurisdiction to legalize medical marijuana when Governor Quinn signed HB 1 into law on August 1.

As such, companies that employ individuals in states with medical marijuana may be uncertain as to whether or under what circumstances they can take action with respect to an employee that fails a drug test or otherwise admits to being a medical marijuana patient.

Civil Protections – Where Do We Stand Today?  

Most of the states that have enacted a medical marijuana law have statutory language that is silent about medical marijuana patients’ civil protections.  Of the 21 jurisdictions that have medical marijuana on the books, 15 do not provide for any form of employment protections.[2]  In fact, supreme courts in California, Oregon, Washington and Montana have all upheld employer decisions to discharge employees that were medical marijuana patients.  The plaintiffs in these lawsuits have argued that medical marijuana users are protected under such statutes because the law itself creates the sought-after employment protections, that the employer’s decision to discharge the user violates the public policy of the state, and/or that the employer discriminated against them on the basis of a disability when it failed to accommodate their medical marijuana use.  The courts, in response, have held that the medical marijuana statutes in their state only protect patients from criminal sanctions and do not create any civil remedies or protections.  As such, the courts have held that these statutes do not create a clear public policy that might otherwise support a wrongful termination claim or establish that medical marijuana users belong to a protected class.  With respect to claims based on asserted disabilities, courts, like the Supreme Court of Oregon, have held that federal law preempts any argument that an individual is protected from disability discrimination on the basis that they are a medical marijuana patient.

Another argument that was recently tested by a plaintiff in Colorado is that an employer’s decision to discharge a medical marijuana user who fails a drug test violated the state’s “lawful activities” statute.  Colorado, like many states, prohibits employers from taking action against an employee for engaging in lawful activities or using lawful products outside of the workplace.  In a decision dated April 25, 2013, the Court of Appeals of Colorado held that the state’s “lawful activities” statute did not bar the employer from discharging an employee who tested positive for marijuana after a random drug test and who was also a licensed patient.  Coats v. Dish Network, LLC, case nos. 12CA0595, 12CA1704 (Co. Ct. App. April 25, 2013).  The court held that since the Colorado statute did not specify whether an activity’s “lawfulness” was determined by state or federal law, and marijuana is illegal under federal law, employees that use medical marijuana are not shielded by the statute from the risk of termination.

Despite the lack of civil protections in a majority of jurisdictions that have legal medical marijuana, a few states do provide clear restrictions on an employer’s ability to discriminate against a medical marijuana patient.  In Connecticut, Maine and Rhode Island, medical marijuana patients are given protected status and employers are prohibited from discriminating against an employee merely due to their status as a medical marijuana patient.  Under Illinois’ HB 1, Illinois also now prohibits such discrimination.

In addition, Arizona and Delaware have adopted much more explicit and impactful statutorily language that bars an employer from discriminating against a registered and qualifying patient who has failed a drug test for marijuana metabolites or components.  The only exceptions to this rule are that an employer may act upon the results of a failed drug test if the patient “used, possessed or was impaired by marijuana on the premises of the place of employment or during the hours of employment” or failing to do so would jeopardize an employer’s “monetary or licensing related benefit under federal law or regulations.”  See ARS 36-2813 and Del. Code Title 16, § 4905A.  Neither statute has been tested in the courts, but the language of these statutes appears to plainly prohibit employers from firing an employee who is a qualified medical marijuana patient based solely on a failed drug test.  Rather, in these two states, most employers will need to prove that their decision was based on the fact that the employee used, possessed or was impaired by marijuana while on the job.

Uncertainties Around Illinois Statute

Whether Illinois’ medical marijuana statute provides similar protections is a more uncertain question.  With regard to employer liability under the proposed statute, HB 1’s provisions are generally couched in what they do not prohibit, leaving open to interpretation what it may bar with regard to workplace decision-making.  HB 1 first states that it does not prohibit “an employer from enforcing a policy concerning drug testing, zero-tolerance or a drug free workplace provided the policy is applied in a nondiscriminatory manner.”  The bill also states that employers are not limited from “disciplining a registered qualifying patient for violating a workplace drug policy.”  These initial provisions suggest that Illinois’ statute is in line with the majority of jurisdictions, but then it goes on to provide that “[n]othing in this Act shall limit an employer’s ability to discipline an employee for failing a drug test if failing to do so would put the employer in violation of federal law or cause it to lose a federal contract or funding.”  This language, like that in Arizona and Delaware, appears to potentially prohibit employers from relying upon a failed drug test for marijuana unless the employer has contrary obligations under federal law or regulation.  The statute continues down this road by also stating that it does not create a cause of action against an employer for actions based on a good faith belief that the medical marijuana user used, possessed or was impaired by marijuana while working.  It also provides that an employer may consider a patient to be impaired when they exhibit “articulable symptoms … that decrease or lessen [the employee’s] performance of the duties or tasks of the employee’s job position.”  This provision further states that if an employee is disciplined under this section, that they must be given an opportunity to contest the employer’s determination.

Taking these latter provisions into account, there are strong arguments in favor of the position that Illinois’ medical marijuana does provide similar civil employment protections as found in Arizona’s and Delaware’s statutes.  First, the bill states that employees cannot sue an employer for actions that were based on a good-faith belief that the employee was impaired, that the belief that an employee is impaired must be based on “articulable symptoms,” and that  employees must have an opportunity to rebut the idea the they were impaired.  These provisions suggest that an employer may be found to have acted in bad faith and subject to liability if it discharges an employee without an articulable basis for why it believed that the employee was impaired or fails to give an employee a chance to challenge an assertion that they were impaired on the job.  In addition, the statute appears to tie the ability of an employer to discipline an employee for failing a drug test to an employer’s obligations under federal law.  This framework creates a plausible argument that the statute does provide protections for medical marijuana users who do not use or are not impaired by marijuana on the job.  However, the pronouncement that employers are not limited in keeping drug testing, zero tolerance, or drug-free workplace policies seems to conflict with such a finding.  Perhaps one way to read these provisions consistently is to find that the statute allows employers to maintain such policies, but that they must treat medical marijuana patients in the same manner as other employees that have been prescribed legal medications.  In reality, the only way we will know the answer to this question is when the law is inevitably relied upon by a qualified patient who is fired for failing a drug test that is positive for marijuana.

Recommendations for Employers in Medical Marijuana Jurisdictions

So, how should employers respond to these increasingly more common medical marijuana laws?  For those employers who have federal contracts or are otherwise subject to federal regulations concerning drug-free workplaces, your practices do not need to change.  According to the Department of Transportation, which regulates and provides drug testing requirements for certain safety-sensitive positions, it is “unacceptable for any safety-sensitive employee subject to drug testing under the Department of Transportation’s regulations to use marijuana.”  Thus, employers subject to such or similar regulations should continue to comply with applicable federal law.

Employers that are not subject to federal drug testing regulations should review their substance abuse policies to ensure compliance with local and state law.  Employers in states that generally do not provide for employment protections should still consider whether their state has a “lawful activities” or “lawful products” statute or whether courts in their state may be more favorable to finding a clear public policy protecting medical marijuana users.  In light of the holdings of those decisions that have addressed the issue, courts in these states will likely find that their state law does not establish a clear public policy in favor of medical marijuana patients.  However, this analysis may differ in Colorado and Washington, both of which now allow for legal recreational use.  In those states that do provide for some form of employment protection, you should carefully revise your policies to be consistent with those laws.

Employers should also consider whether or when they will conduct drug testing.  With the passage of these laws, employers should expect that more of their employees may be using marijuana outside of the workplace.  Similarly, employers should expect more challenges, based on the long period of time that marijuana metabolites remain in an individual’s system, from employees that have failed drug tests but who claim they were not impaired while working.  In Arizona, Delaware and Illinois, employers should revise their substance abuse policies to make sure they conform to state law and ensure that employees who are qualified patients are not disciplined solely on the basis of a failed drug test.  Lastly, employers should train their supervisors and managers to recognize signs of impairment (whether due to marijuana, alcohol, or other substances) and how to deal with inquiries from employees regarding their use of medical marijuana.
