Driehaus asked Kasich to declare a public health crisis "and immediately make available $400 million in emergency Rainy Day Funds for local communities to help beat back the heroin and opioid torrent."
Ohio currently has a surplus of more than $2 billion in tax dollars, known as the Rainy Day Fund.
Her letter comes a day after Cincinnati Vice Mayor David Mann and Cincinnati Council Member P.G. Sittenfeld also called on the governor to release emergency funding to address the crisis.
The total number of overdoses rose to 88 overdoses by the end of Thursday. There were 24 overdoses Thursday, 43 overdoses Wednesday and 21 Tuesday in the biggest spike in heroin overdoses the Tri-State has ever seen.
