A Wells woman is out of a job because of the CBD supplement she takes to combat her endometriosis.

Audra Dieffenbach had no idea the supplement she takes to manage her endometriosis pain would cause her to lose her job.

Dieffenback uses a supplement called Amethyst Elixir, made by a Freeport company. The cannabidiol, or CBD oil, is made from hemp and contains less than 0.3% THC, which is the legal limit under federal law.

She started taking the supplement two years ago to combat what she says was debilitating pain caused by endometriosis. Endometrios is a disorder in which tissue that normally lines the uterus grows outside the uterus.

"People with endometriosis will know that when you finally find something that actually relieves some of the pain, it's such a relief," says Dieffenbach.

Dieffenbach was hired as a temp worker by MaineHealth. She loved the patient-oriented work and was thriving in her position. She was doing so well, she says her direct managers suggested she apply for a promotion, a full-time position.

A drug test was part of her application process. MaineHealth receives federal funding, and therefore all employees must comply with a drug test.

"My first reaction was absolute shock," says Dieffenbach, about learning her drug test came back positive.

While her supplement contains just trace levels of THC, Dieffenbach believes it built up in her system, causing her to fail the test.

MaineHealth says because it gets federal reimbursements it's required by law to test for illegal drugs -- including marijuana -- which is still illegal at the federal level.

MaineHealth Associate Vice President Jon Porter released a statement on behalf of the company:
