The nation's opioid abuse epidemic might be even worse than people think.
New research by the CDC suggests the total number of deaths from opiod abuse might be underestimated.
Latest figures show that 91 people die from opioid overdose every day.
In a report presented Monday, CDC researchers said autopsy reports on people who are prescribed opioids for pain sometimes note only the immediate cause of death but don't mention opioid use.
