Cannabis and the Workplace: An Overview of Employees’ Rights
We frequently get inquiries from employees who are unsure of their rights regarding cannabis. Their confusion is understandable, since marijuana is very much in a legal gray area. Although possession of any amount of marijuana is a federal crime, Congress and Justice Department priorities have sharply limited enforcement of federal law against most people who have marijuana only for personal use. Under Massachusetts state law, different statutes authorize medical and recreational sale and use of cannabis. State-licensed dispensaries sell cannabis in cities and towns across Massachusetts for medical purposes and increasingly for non-medical purposes as well. Depending on the situation, employees who use cannabis may or may not have legal protections. This general overview will focus on three areas: drug testing, the use of medical cannabis under state law, and recreational marijuana.
Massachusetts employers may require employees to take drug tests under some circumstances, but the employers must meet specific legal criteria. Under federal and state laws against disability discrimination (the Americans with Disabilities Act and Chapter 151B), an employer may be permitted to require an applicant to undergo a test for illegal drugs after offering the applicant a job, if the test is relevant to the employee’s ability to perform the job and is applied equally to all employees in the same job category. After an employee has been hired, any drug test must be job-related and consistent with business necessity. Because marijuana is illegal for federal purposes but legal under state law, it is unclear whether Massachusetts employers may test for marijuana even if they can test for other drugs; however, if there is a specific federal requirement to test for marijuana, such as for truck drivers, the federal law would govern.
