AUGUSTA, Maine (AP) Supporters of a new Maine law say the state’s schools and summer camps will have better access to epinephrine devices due to a new law in the state.

Democratic Gov. Janet Mills signed the proposal into law on Wednesday. Supporters say it expands the definition of epinephrine pens and epinephrine auto-injectors in Maine to include newer and more cost effective evidence-based delivery methods.

Epinephrine devices are used when someone sufferers a severe allergic reaction.

The EpiPen is a common method of delivery, but the devices increased in price by more than 450 percent from 2007 to 2015.
