Here's one expert's theory for why the opioid epidemic has a disproportionate impact on whites
The rate of white Americans dying annually from drug overdoses has roughly doubled from 2002 to 2014, while the rate of black Americans and Hispanics who die from drug overdoses has remained almost unchanged over that same time frame, according to recently released data from the CDC.
Dr. Andrew Kolodny, the chief medical officer for The Phoenix House and a leading expert on opioid addiction, told Business Insider these trends might have a direct connection to some doctors allowing racist stereotypes to influence the way they prescribe opioid pain killers.
"What's happening is we're overexposing whites to prescription opioids," he said. "Doctors prescribe narcotics more cautiously to black patients. It appeared the doctor may be more worried about addiction or diversion of the pills onto the black market if the patient was black and if the patient is white, they're overprescribing."
While it's impossible to know doctors' reasons for prescribing certain medications - and individual doctors of course vary significantly in their background and world view - studies have shown that some doctors are less likely to prescribe opioid painkillers to black patients, while other research has suggested that black patients may be less likely to report serious pain.
A 2003 study in The American Journal of Public Health found that opioid painkillers were far less likely to be prescribed to black patients than to whites for migraines or back pain. And a 2013 study from the journal Pediatrics found that black patients were much less likely than white patients to be prescribed those painkillers for abdominal pain.
A 2011 study from the journal Clinical Orthopedics and Related Research noted that some black patients may underreport the severity of their pain. Still, the study acknowledged that physicians were a major contributor to the racial disparities in the way pain is treated, "reflect[ing] limited awareness of their own cultural beliefs and stereotypes regarding pain, minority individuals, and use of narcotic analgesics."
Whatever the causes of the disparity, it's clear far more white people are dying from opioid overdoses today.
White Americans of all ages are about twice as likely to die from a drug overdose as black Americans, and four times as likely to die of a drug overdose as Hispanics, based on the CDC data from 2014. These drug overdoses are mostly due to opioid addiction from both prescription pain killers and heroin.
Broken down by certain age groups, the data is even more staggering.
In 2014, white Americans between the age of 25-34 were dying by overdose at a rate that's roughly three times what it was in 2002, while the death rate for black Americans and Hispanics went relatively unchanged over that 12-year period.
White Americans between 15 and 24 years old were roughly six times more likely to die from a drug overdose in 2014 than black Americans and about four times as likely to die than Hispanics.
For white Americans between the age of 35 and 44 as well as between 45 and 54, a large uptick in the death rate from drug overdoses was also experienced between 2002 and 2014. Meanwhile, the rate of drug overdose deaths for black Americans and Hispanics remained unchanged.
More than 47,000 people died of drug overdoses in 2014, per the CDC.
