Medical Marijuana Complicates Employer Drug Testing

Residents in 14 states and Washington can now legally obtain prescriptions for medical marijuana. However, they may still be denied employment based on failing a drug test that screens them for doing something that is legal under state law. Lawmakers are still uncertain about how to enforce a uniform policy for a drug that the federal government has not recognized as having a legitimate medical purpose.

To date, only one state has written immunity for firing over medical marijuana into its state law. Only the Rhode Island Medical Marijuana Act offers protection to medical marijuana cardholders for students, employees and tenants.
