The rights of patients who need to use medical marijuana are being questioned as cases where those who use it are at disadvantage continue to emerge.

A graduate student, who is studying textiles at the University of Rhode Island, reportedly sued a textile company for refusing to hire her for a two-month internship because she uses medical marijuana as she is a patient who suffers from frequent and debilitating migraine headaches, according to the media outlet Seattle PI.

Her lawyers reportedly called the decision discrimination. This is one of the many cases that show that the rights of medical marijuana users need to be considered, especially because if they are discriminated for using it, legalization becomes an "empty promise," according to Carly Iafrate, the attorney who filed the lawsuit for the student Christine Callaghan.

"People with disabilities simply cannot be denied equal employment opportunities on the basis of the type of medication required to treat their particular condition," stated Iafrate.

Patients who have been fired, disciplined or denied a job after testing positive due to their use of medical marijuana have reportedly previously sued in states including New Mexico, Maine, Colorado and New Jersey.

Another case regarding the rights of medical marijuana patients arose recently when Scott Waselik was reportedly arrested on possession of marijuana charges after being stabbed in the chest by his roommate last year, according to NJ.com. For more than a year, Waselik has reportedly been arguing that he had a right to the marijuana found in his home as he's a medical marijuana patient.

A judge has reportedly ruled that police didn't have the authority to enter Waslike's home in the first place and that the marijuana seized as evidence can't be used against him at trial, the New Jersey Herald reported.
