Can I be fired because I use medical marijuana for a disability?

Compassionate use laws generally don't extend to the employment arena.


I have glaucoma, and my doctor gave me a prescription for medical marijuana to help me control my eye pressure. I use marijuana on the weekend and two evenings per week; I never use it during the work day or before work. I'm up for a promotion at my job, but my employer requires drug testing for this position. If I test positive for cannabis, can my employer use it against me?  


So far, courts that have considered this question have ruled against employees. Your legal right to use medical marijuana protects you from criminal prosecution, but not from employer drug testing programs. If you were taking a different legally prescribed drug for your condition, you would most likely be protected by the Americans with Disabilities Act (ADA). However, this protection hasn't been extended to medical marijuana.  

The ADA prohibits discrimination against employees with disabilities. A disability is a physical or mental impairment that substantially limits a person's major life activities, including major bodily functions. There may be people with glaucoma who do not have a disability under the ADA, based on this definition. However, if your glaucoma substantially limits your ability to see (a major life activity), you are protected.  

Employees with disabilities have a right to reasonable accommodation to allow them to do their jobs. This extends to the measures an employees uses to control and function with a disability. For example, an employer might have to lower a desktop to accommodate an employee's wheelchair. The same rule applies to drugs that are legally prescribed for a disability. The employer may have a legal duty to accommodate the employee's drug use, including the side effects that the drugs have on the employee, under the ADA. If, for example, an employee takes medication for depression that makes him or her drowsy in the morning, the employer may have to alter the employee's start time to accommodate that side effect.  

But medical marijuana hasn't been treated this way, at least so far. Courts have held that a person's right to use marijuana for certain medical conditions doesn't extend to a right to have that use accommodated by an employer. Marijuana use remains illegal under federal law, and the ADA explicitly does not protect employees who use illegal drugs. This lack of consistency between federal and state laws has led to the unfortunate result that an employee can be fired just for following doctor's orders.
