By the end of 2013, the country's quiet opioid addiction crisis was no longer so quiet. Opioid overdose deaths that year topped 16,000, more than four times the same statistic for 1999. That prompted a number of measures at the state and federal level to rein in opioid prescriptions, including a move by the DEA in October 2014 to tighten its policies around some of the most commonly prescribed opioids.
The new DEA policy—aimed at popular opioids such as Vicodin and Lortab—imposed restrictions on doctors' prescribing and made it more difficult for patients to get refills. In one sense, the policy was a success: Prescriptions for those drugs decreased almost immediately. But new research adds to an increasing body of evidence that restricting opioid prescribing has not solved the opioid crisis but instead worsened it.
Since the DEA policy shift, opioid overdose deaths continued to grow with more than 40,000 fatal opioid overdoses in 2016. And while prescription opioid overdose deaths have slightly decreased—there were about 14,000 that year—overdose deaths from heroin and non-prescription synthetic opioids such as fentanyl went through the roof. Heroin and illicit synthetics accounted for nearly two-thirds of all opioid overdose deaths in 2016.
In the new study, published this week in the British Medical Journal, researchers examining the impact of the DEA policy shift found evidence that while the change indeed lowered prescribing rates for the opioids in question, it was also linked to an increase in illicit online sales of those drugs in Dark Web drug markets.
The researchers used software called DATACRYPTO to crawl encrypted Dark Web marketplaces where people can anonymously buy damned near anything, from drugs to guns to credit card numbers. DATACRYPTO harvested data on which drugs were for sale, their country of origin, and the number of customer comments on each seller's comments page. Researchers used that last figure as a proxy for how much of a drug that seller sold. They examined sales of prescription opioids, sedatives, stimulants, and steroids, as well as heroin. It was only with prescription opioids that they found a significant Dark Web sales bump.
Here's what they found: "The sale of prescription opioids through US cryptomarkets increased after the schedule change, with no statistically significant changes in sales of prescription sedatives, prescription steroids, prescription stimulants, or illicit opioids."
According to their data, prescription opioids doubled their market share of U.S. Dark Web drug sales thanks to the DEA policy change. By July 2016, opioids represented 13.7% of all drug sales in U.S. cryptomarkets, compared with a modeled estimate of 6.7% of all sales.
While the researchers were careful to not make claims of causation—only correlation—their conclusion speaks for itself: "The scheduling change in hydrocodone combination products coincided with a statistically significant, sustained increase in illicit trading of opioids through online US cryptomarkets. These changes were not observed for other drug groups or in other countries. A subsequent move was observed towards the purchase of more potent forms of prescription opioids, particularly oxycodone and fentanyl."
Not only is the DEA policy change linked to increased Dark Web opioid sales, it is also linked to a move toward more powerful, and thus more dangerous, opioids. The researchers noted that while fentanyl was the least purchased Dark Web opioid in the summer of 2014, it was the second most frequently purchased by the summer of 2016. Fentanyl killed as many people as prescription opioids that year.
This study—one of the few that examines supply reduction (as opposed to demand reduction) as a means reducing drug use—strongly suggests that supply-side interventions carry unintended consequences, especially the resort to more dangerous and more powerful substitutes. The study's authors refer to this effect as "the iron law of prohibition, whereby interventions to reduce supply, such as increased enforcement and changes to drug scheduling, lead to illicit markets dominated by higher potency products."
Perhaps better than restricting opioid prescriptions, which has deleterious impacts on the tens of millions of Americans suffering chronic pain, or other supply-side interventions, would be increased access to addiction treatment, as well as greatly expanded harm reduction measures to try to get people off opioids and keep them alive in the meantime.
