Employer Concerns – Significant to Review

  • Medical marijuana: Employers are not required to accommodate employee use of marijuana on site.
  • An employee who is legally using medical marijuana to treat a disability is entitled to reasonable accommodation under the state disability discrimination law.
  • Employers with six or more employees must accommodate off-site, off-duty use of medical marijuana, unless there is an equally effective alternative treatment available or it would cause the employer undue hardship.
  • Employers are not required to accommodate recreational marijuana use in the workplace.
  • Employers may enforce workplace policies restricting marijuana consumption by employees.
  • Regarding obligations and rights related to drug testing in Massachusetts (MA), give high attention to MA case decisions.


  • Although there is no specific drug testing law for Massachusetts employers, in general because of case law decisions, an experienced, state-specific attorney should be involved before implementing drug testing-related policies and programs.
  • Massachusetts has narrow privacy law which has implications to an employer’s drug testing operations.




  • Must be on private property to consume.
  • Prohibited to be smoked, vaped or eaten in public and cannot be smoked where tobacco is prohibited.
