The US Drug Enforcement Administration says that much less fentanyl is current within the nation’s illicit capsule provide and that’s serving to drive down overdose deaths in america. However consultants say that there are limitations to this declare and that many different elements are in all probability taking part in a task.
About 5 out of each 10 fentanyl capsules that the company examined this 12 months had deadly doses of the artificial opioid painkiller fentanyl, down from about 7 in 10 final 12 months, DEA Administrator Anne Milgram stated final week at a summit for households who’ve misplaced a beloved one to a fentanyl overdose.
Federal knowledge additionally reveals that overdose deaths dropped practically 15% between this June and final. There have been about 16,000 fewer lives misplaced in the newest 12-month interval, based on estimates from the US Facilities for Illness Management and Prevention – and the overwhelming majority of the lower was in deaths involving fentanyl and different artificial opioids.
“Decreases in drug associated deaths and the lethality of capsules equals lives saved,” Milgram stated in a statement. “The cartels have decreased the quantity of fentanyl they put into capsules due to the stress we’re placing on them.”
In Might, the DEA launched a report outlining the illicit drug threats going through the US. The company’s “high operational precedence is to relentlessly pursue and defeat the 2 Mexican drug cartels – the Sinaloa Cartel and the Jalisco Cartel – which can be primarily answerable for driving the present fentanyl poisoning epidemic in america,” the report stated.
The DEA didn’t reply to CNN’s requests for extra details about its fentanyl capsule testing, together with the variety of capsules that had been examined for this evaluation and their supply.
Specialists say there are another vital gaps within the DEA evaluation that weaken the potential hyperlink between the quantity of fentanyl current within the drug provide and the drop in overdose deaths.
For instance, the DEA examined capsules, however consultants say illicit fentanyl is extra generally discovered and utilized in powder type.
The newest testing knowledge from the Heart for Forensic Science Analysis and Training reveals a slight downward pattern within the common purity of fentanyl powder in a drug provide that’s extremely variable, stated Dr. Alex Krotulski, director of toxicology and chemistry on the group, which companions with teams throughout the US to check and analyze drug samples.
“Modifications within the drug provide can have instant impacts on fatalities, however it might be my speculation that these adjustments must be very abrupt and really vital adjustments,” he stated. The small dip within the quantity of fentanyl within the drug provide within the knowledge from his lab could be removed from sufficient to clarify 1000’s of fewer deaths.
The measurement that the DEA makes use of to outline a lethal dose of fentanyl – 2 milligrams – can be subjective. Particular person responses to fentanyl can fluctuate primarily based on the individual’s tolerance to the drug, in addition to bodily and genetic traits.
“There simply is a lot variability and no set method to put a quantity on that,” Krotulski stated. And broader variability – in routes of administration and the combo of different contaminants within the drug provide – makes it laborious to tie drops in overdose deaths on to the adjustments in fentanyl that the DEA discovered.
“It’s actually not simply the lower barely within the quantity of fentanyl in capsules, in my view,” he stated. “It actually is probably going a collective effort of what’s happening within the public well being and public security realm.”
In a press release final week, Dr. Rahul Gupta, director of the White Home Workplace of Nationwide Drug Management Coverage, highlighted efforts that the Biden administration has made to assist scale back drug overdoses.
“Over the previous 4 years, we have now eliminated decades-long limitations to therapy for tens of millions of Individuals, we have now made life-saving opioid overdose reversal drugs like naloxone extra accessible and inexpensive throughout the nation, and we have now invested historic ranges of funding to crack down on the provision of illicit fentanyl on the border,” he said.
Milgram additionally stated that many elements have contributed to the lower in overdose deaths.
“A lot work stays, and one demise is simply too many, however right now we are able to discover some consolation in the truth that the work we’re all doing collectively – to implement our legal guidelines, to teach Individuals on the risks of fentanyl, to extend entry to naloxone and [medications for opioid use disorder] – is saving lives,” she stated final week.
Dr. Daniel Ciccarone, a professor on the College of California, San Francisco whose analysis has targeted on illicit drug traits within the US, agrees that there are limitations to the DEA’s evaluation of the quantity of fentanyl present in capsules, however he says it’s one metric that may function a useful place to begin.
“Something that reduces fentanyl publicity goes to result in a decline in deaths, as a result of that’s probably the most highly effective lethal agent on the market proper now,” he stated.
Current anecdotes from his work align in ways in which recommend there was a “provide shock” that might point out much less fentanyl out there: Folks in each San Francisco and Ohio have advised him that the drug is getting weaker, dearer and tougher to search out, he stated.
The sharp decline in overdose deaths additionally makes this a possible concept – opposite to different explanations that might result in extra gradual change, he stated.
“The sudden decline of double digits jogs my memory of historic provide shocks,” Ciccarone stated, substantial adjustments which can be just like the best way the Covid-19 pandemic affected the provision chain.

“Individuals are delicate to cost, whether or not you’re a professional client or consuming an illegitimate drug, and people translate comparatively shortly,” he stated. “So if the provision shock is significant and it adjustments the road worth or purity in a significant method, consumption goes down. And when consumption goes down on a inhabitants degree, you’re going to see profit. You’re going to see overdoses go down.”
Nonetheless, Ciccarone has just a few different theories to clarify the drop in overdose demise, together with two that he favors extra strongly than the thought of a provide shock.
First, he theorizes that the dimensions of the at-risk inhabitants is reducing; youthful individuals who use illicit medicine usually are not in search of out fentanyl to the identical diploma because the older cohort who had been uncovered to fentanyl when it adulterated the heroin provide.
And second, he means that the decreases could merely be a return to common after a major spike throughout the top of the Covid-19 pandemic.
In any case, he says, there’s no method to pinpoint a single issue driving overdose deaths down, and the pattern could not stick. The illicit drug market is extremely versatile and resilient.
“I’m not 100% satisfied that this phenomenon, no matter it’s and no matter’s inflicting it, lasts one other 12 months,” Ciccarone stated. “We’ve to anticipate the sudden transferring ahead. If it occurs – unexpectedly, to me – that this persists, then hallelujah.”
