The Drug Enforcement Administration (DEA) is taking action against an increasing number of doctors for prescribing opioids to patients who overdose, according to CNN. The DEA took action against 479 doctors in 2016, compared with 88 doctors in 2011. Most people who misuse prescription opioids get them for free from a friend or relative, according to the Centers for Disease Control and Prevention (CDC). “Those who are at highest risk of overdose (using prescription opioids nonmedically 200 or more days a year) get them in ways that are different from those who use them less frequently,” the CDC notes on its website. Among those at highest risk of overdose, 27 percent get opioids using their own prescriptions. A study published last year in the Annals of Internal Medicine found 91 percent of people who survived an opioid overdose were able to get another prescription for opioids.
