DUBUQUE, Iowa (AP) — A Dubuque woman says she has a state cannabis card allowing her to give an oil extracted from marijuana to her son, but she’s not allowed to do so in his care center.

Instead, Jennifer McFadden says she gives the oil to her 12-year-old son, who has severe epilepsy, twice a day in the facility’s parking lot.

She tells The Des Moines Register that the agency which operates the center says it can’t allow the oil into the facility. She says the agency told her that federal authorities still consider it a strictly controlled marijuana product.

The company that sends McFadden the oil says it has a large amount of the chemical, cannabidiol, which many families believe can reduce epileptic seizures
