The C.D.C.’s numbers show that 91 people in the United States die every day from opioid overdose.

The number of bodies from accidental overdoses that have come to the Montgomery County Coroner’s Office in the first 33 days of the year — 163 — is already more than half the yearly totals for the past two years. In 2015, the total was 259; last year, the number of deaths from January to September was 253, figures from the office show.

In Ohio, fatal overdoses more than quadrupled in the past decade and by 2007 had surpassed car accidents as the leading cause of accidental death, according to the Department of Health. In 2015, 3,310 deaths were recorded in the state from unintentional drug overdoses, a 21.5 percent increase from the previous year, according to the C.D.C.

Addiction is so entrenched and widespread that police officials say there are now third and fourth generations of prescription drug abusers. These days, hospitals in Cincinnati require drug testing of new mothers and infants because of a surge in newborns exposed to addictive drugs.

The five states with the highest rates of death linked to drug overdose were West Virginia (41.5 per 100,000), New Hampshire (34.3 per 100,000), Kentucky (29.9 per 100,000), Ohio (29.9 per 100,000), and Rhode Island (28.2 per 100,000), according to the C.D.C.
