Medical Marijuana in the Workplace – 4 Considerations for Employers and Employees
In recent years, a number of states have passed bills that decriminalize or legalize medical or recreational marijuana use. As of the writing of this article, 30 states have legalized medical marijuana use, ten states have adopted measures legalizing marijuana for recreational and medicinal use, and almost all of the remaining states have at least considered some form of marijuana legalization. It is unclear of course if or how the current presidential administration will impact marijuana policies across the US, but the immediate results suggest that little will change.
1) Medical marijuana and the ADA
The Americans with Disabilities Act (ADA), requires employers to provide reasonable accommodations to employees with disabilities so that they can perform the essential functions of their job, but also prohibits the “illegal use of drugs”. Medical marijuana is often prescribed to individuals whose disabilities are typically recognized by courts under the ADA, and the use of medical marijuana can be essential to an employee’s ability to perform her job and may be the only workable accommodation for the employee.To d Tod To date, because marijuana remains a prohibited substance, courts have generally found that employers are not required to accommodate the use of medical marijuana under the ADA or state-equivalents.
2) State Law Accommodations
However, while doctor-prescribed marijuana use is still considered an illegal use of drugs that is not covered by the ADA, that may not be the case under all state discrimination statutes. Some states, including Connecticut and Rhode Island, have laws prohibiting discrimination on the basis of medical marijuana status and have enacted laws which may require employers to provide an accommodation that does not impose an undue burden on the employer.
3) Case Law
Courts have also begun to recognize an employer’s duty to accommodate under such state laws. In 2017, the Massachusetts Supreme Judicial Court held that an employer should have at least engaged in the interactive process to determine whether an employee’s use of marijuana to treat her Crohn’s disease could potentially have been accommodated. Similarly, also in 2017, a Rhode Island court, and a federal district court in Connecticut, held that a state’s medical marijuana statute may be violated by an employer if the employer refuses to hire an applicant because of her medical marijuana use. In both cases, the courts explicitly rejected employers’ arguments that the applicants were not qualified because marijuana was illegal under federal law.
4) Human Resources – What to do?
These decisions represent a shift from past precedent in that it now appears employers may have a duty to accommodate medical marijuana use. As such, it is important for employers in states where medical marijuana is legal to (a) carefully review their local anti-discrimination laws (b) consider revising their company policies and practices to contemplate accommodations for medical marijuana use, and (c) seek professional guidance.
