The Centers for Disease Control and Prevention released a new study on opioid painkiller prescription rates last Tuesday. The study looked at prescriptions per 100 residents throughout the U.S. Southern States. 7 of 12 states with the highest prescription rates were found in the South. Alabama had the highest prescription rates in the nation. North Carolina, Tennessee, South Carolina, Mississippi, Louisiana and Arkansas all joined Alabama with rates about 96 prescriptions per 100 residents.
