Prescription Opioids Play Only Minor Role in Overdose Crisis

By Pat Anson, PNN Editor

The role of prescription opioids in the nation’s overdose crisis continues to shrink.

In a new study from the drug testing firm Millennium Health, researchers say multiple substances were found last year in nearly 93% of urine samples in which fentanyl was detected. That is not altogether surprising, as “polysubstance” use increased as fentanyl came to dominate the illicit drug supply, appearing in more and more street drugs such as heroin, cocaine and methamphetamine.

What is surprising is the minimal role that prescription opioids now play. In 2013, opioid pain medication was the most common substance found in fentanyl-positive drug tests in the United States, appearing in over 70% of urine samples.  A decade later, prescription opioids were detected in less than one in ten samples — ranking far behind methamphetamine, cannabis, cocaine and heroin.

In fact, you are about twice as likely to find two other medications -- benzodiazepines (15.8%) and gabapentin (13.3%) -- than you are prescription opioids (7.6%) in urine samples testing positive for fentanyl.

Substances Detected in Fentanyl-Positive Drug Tests (2023)

Millennium based its findings on over 4.1 million urine drug tests (UDTs) collected from 2013 to 2023 and analyzed through mass spectrometry. Because many of those samples came from people being treated for a substance use disorder, they offer a clear insight into drug trends that are driving the overdose crisis.

Now in its “fourth wave,” Millennium says a tidal shift has occurred in the so-called opioid epidemic, with illicit drug users far more likely to use non-opioid substances like stimulants than prescription opioids.

“National, regional, and state-level UDT data all suggest that people who use fentanyl are now, intentionally or unintentionally, much more likely to also use methamphetamine and cocaine,” the report found. “The results of our analyses also reveal shifting patterns of opioid use among those who use fentanyl. More specifically, they showed progressive declines in prescription opioid use from 2015 to 2023.”

The declining role of prescription opioids can be traced back to the 2016 CDC opioid guideline and a multiyear campaign by the DEA to slash opioid production quotas, which has reduced the supply of oxycodone and hydrocodone by about two-thirds. There is little evidence either of those federal efforts reduced the number of overdoses. The CDC estimates there were over 111,000 drug deaths in the 12-month period ending in September 2023 — nearly double the number of fatal overdoses in 2016.

The growing use of stimulants such as methamphetamine makes it difficult for public health campaigns to address the problem. Unlike opioids, there are no FDA-approved medications for stimulant use disorder, leaving behavioral therapies and abstinence as the only “evidence-based” treatments for people with a stimulant problem.

“Stimulants are a serious national challenge emphasizing the need for continued progress on the national plan to address methamphetamine supply, use, and consequences,” Millennium said.

Stimulants Involved in Growing Number of Fentanyl Overdoses

By Pat Anson, PNN Editor

The number of drug deaths involving both fentanyl and stimulants has soared in recent years, according to a new UCLA study that highlights the complex and changing nature of the U.S. overdose crisis.

Stimulants such as cocaine and methamphetamine are now involved in nearly a third of fentanyl-related overdoses, the most of any other drug class. Fentanyl is a synthetic opioid up to 100 times more potent than morphine and 50 times as potent as heroin.

In 2010, researchers say there were only 235 fatal overdoses in the U.S. involving illicit fentanyl and stimulants. In 2021, there were 34,429 drug deaths linked to fentanyl and stimulants, a 14,550% increase in a little over a decade.

"We're now seeing that the use of fentanyl together with stimulants is rapidly becoming the dominant force in the US overdose crisis," said lead author Joseph Friedman, PhD, an addiction researcher at the David Geffen School of Medicine at UCLA. "Fentanyl has ushered in a polysubstance overdose crisis, meaning that people are mixing fentanyl with other drugs, like stimulants, but also countless other synthetic substances. This poses many health risks and new challenges for health care providers.

“We have data and medical expertise about treating opioid use disorders, but comparatively little experience with the combination of opioids and stimulants together, or opioids mixed with other drugs. This makes it hard to stabilize people medically who are withdrawing from polysubstance use."

People who overdose on stimulants and other non-opioid substances mixed with fentanyl may not be as responsive to naloxone, which only works as an antidote to opioids.

The study findings, published in the journal Addiction, highlight the four “waves” of the overdose crisis, which began with an increase in deaths from prescription opioids (Wave 1) in the early 2000s, followed by a rise in heroin deaths (Wave 2) in 2010, and fentanyl-related overdoses in 2013 (Wave 3). The fourth wave — overdoses from fentanyl and stimulants — began in 2015 and continues to escalate.

The Four Waves of Overdose Crisis

SOURCE: ADDICTION

Since cocaine, methamphetamine and other stimulants are not opioids, the findings undercut the long-held theory that the overdose crisis started with prescription opioids and is still being fueled by people addicted to them. Deaths involving prescription opioids and heroin have been in decline for several years.

Researchers found that fentanyl/stimulant deaths disproportionately affect African Americans and Native Americans. There are also geographical patterns to fentanyl/stimulant use. In the northeast US, fentanyl is usually combined with cocaine, while in the south and western US, fentanyl is most commonly found with methamphetamine.

"We suspect this pattern reflects the rising availability of, and preference for, low-cost, high-purity methamphetamine throughout the US, and the fact that the Northeast has a well-entrenched pattern of illicit cocaine use that has so far resisted the complete takeover by methamphetamine seen elsewhere in the country," Friedman said.

In addition to its low cost, drug users say methamphetamine helps prolong fentanyl’s “high” and delays the onset of withdrawal symptoms.  

Counterfeit pills laced with fentanyl – which are frequently made to look like oxycodone or alprazolam (Xanax) – represent about a quarter of all illicit fentanyl seizures. Researchers say it is difficult to track deaths involving counterfeit pills because they are often mistaken for legitimate medication, so the data is not completely reliable.

In its most recent update on the overdose crisis, the CDC estimates there were a record 111,355 drug deaths in the 12-month period ending April 2023 -- about a thousand more deaths than the year before. Fentanyl and its analogues were involved in nearly 70% of the overdoses, stimulants were linked to about a third of them, and cocaine was involved in about a quarter of the drug deaths.

CDC Study Shows Oxycodone Plays Minor Role in Overdose Crisis

By Pat Anson, PNN Editor

A new study by the CDC highlights the sharply rising death toll in the U.S. caused by illicit fentanyl, while at the same time revealing the minor role played by oxycodone in the nation’s overdose crisis.

The study, released this week by the CDC’s National Center for Health Statistics, looked at overdose death rates from 2016 to 2021. Deaths involving fentanyl more than tripled during that period, rising from 5.7 deaths per 100,000 people in 2016 to 21.6 deaths per 100,000 in 2021. Drug deaths involving methamphetamine and cocaine also rose sharply, while fatal overdoses involving heroin declined.

And what about oxycodone, the most commonly prescribed opioid pain medication? It turns out oxycodone has always played a relatively minor role in the overdose crisis, although regulators and public health officials said otherwise in a concerted campaign against all prescription opioids.

“Overprescribing opioids – largely for chronic pain – is a key driver of America’s drug overdose epidemic,” then-CDC director Dr. Thomas Frieden said in a 2016 news release.

But the facts don’t support Frieden’s claim. In 2016, the year the CDC released its controversial opioid prescribing guideline, there were only 1.9 deaths per 100,000 people that involved oxycodone. By 2021, the rate had fallen 21% to 1.5 deaths -- well below the death rates of fentanyl, methamphetamine, cocaine and heroin.   

Drug Overdose Deaths in U.S. (2016-2021)

CDC researchers used an unusual method to conduct this study. Instead of relying on medical ICD-10 codes in death certificates, which lump drugs together into broad categories, the CDC used a “literal text” analysis.

“To address the limitations of ICD–10- coded mortality data, the National Center for Health Statistics has developed a method that searches the literal text of death certificates to identify mentions of specific drugs and other substances involved in the death. Death certificate literal text is the written information provided by the medical certifier, usually a medical examiner or coroner for drug overdose deaths, that describes the causes, manner, and circumstances contributing to the death,” the researchers explained.

Flawed Data

The literal text method is not foolproof, but it’s an improvement over the ICD-10 codes, which the CDC admitted in 2018 “significantly inflate” the number of deaths involving prescription opioids — flawed data that Frieden used to make his “key driver” of the epidemic claim in 2016.

How inflated were the overdose numbers back then?  Using the old ICD-10 method, which counted illicit fentanyl as a prescription opioid, Frieden’s CDC estimated that nearly 32,500 Americans died from overdoses of opioid medication in 2016. The death toll was later revised downward to about 17,000 overdoses after the CDC came clean about its flawed methodology.

Patient advocate Richard “Red” Lawhern has long been suspicious of CDC data, including studies that use literal text analysis.  

“CDC suggests an incidence of drug overdose deaths ‘involving’ oxycodone at only 1.5 per 100,000.  But they neatly avoid telling us that such a rate is so low that it confounds the non-uniformity of reporting from county to county, creating such statistical noise that the contribution of this agent (oxycodone) to overdose mortality is too small to accurately measure or report,” Lawhern said.  

Another problem is the qualifications of county coroners and medical examiners varies. Some are elected to their positions without any medical training or experience. The death certificates they fill out usually don’t say if a prescription drug was obtained legally or illicitly, or what specific drug or combination of substances caused the death. That is determined later by a toxicology test. As a result, a drug may be “involved” in a death and be listed on the death certificate, but have little or nothing to do with someone’s demise.

“It is startling that CDC has so consistently and deliberately conspired to disguise the fact that oxycodone really isn't significant in drug overdose mortality, and probably never has been,” Lawhern told PNN. 

Of course, every death is a tragedy in some way, regardless of the cause or substance involved. The graphic below helps bring oxycodone’s role into more context – comparing the five leading causes of death in 2021 to those involving fentanyl, oxycodone and the other drugs.

Despite the minor role played by oxycodone in 2021 deaths, efforts continue to restrict its availability. This year the Drug Enforcement Administration reduced the supply of oxycodone for the seventh consecutive year. Since their peak in 2013, DEA production quotas for oxycodone have fallen by 65 percent. The tightened supply has resulted in recent reports of oxycodone shortages and patients unable to get their prescriptions filled.

The DEA justifies the cuts by saying it is concerned about diversion and abuse, but the agency’s own data shows that less than one percent of legally prescribed oxycodone (0.3%) is diverted to someone it was not intended for.

Drug Tests Show Pain Patients on Opioids Less Likely to Use Illicit Drugs

By Pat Anson, PNN Editor

In an effort to reduce soaring rates of drug abuse and overdoses, many physicians have taken their pain patients off opioids and switched them to “safer” non-opioid drugs like pregabalin, gabapentin and duloxetine. Others have encouraged their patients to try non-pharmacological treatments, such as acupuncture, massage and meditation.

That strategy may be backfiring, according to a large new study by Millennium Health, which found that pain patients prescribed opioids are significantly less likely to use illicit drugs than pain patients not getting opioids.

The drug testing firm analyzed urine drug samples from 2019 to 2021 for nearly 55,000 patients being treated by U.S. pain management specialists. About 80% of the patients were prescribed an opioid like oxycodone or hydrocodone, while the other 20% were not prescribed opioids.

Millennium researchers say detectable levels of illicit fentanyl, heroin, methamphetamine and cocaine were far more likely to be found in the urine of non-opioid patients than those who were prescribed opioids. For example, illicit fentanyl was detected in 2.21% of the patients not getting an opioid, compared to 1.169% of those who were. The findings were similar for heroin, methamphetamine and cocaine.

“In all cases, we found that the population that was not prescribed an opioid was significantly more likely to be positive for an illicit drug than those patients who were prescribed opioids,” said lead author Penn Whitley, Director of Bioinformatics at Millennium. “(There was) a 40 to 60 percent increase in the likelihood of being positive if you were not prescribed an opioid.”

Illicit Drug Use By Pain Patients

MILLENNIUM HEALTH

What do the findings mean? Are pain patients getting ineffective non-opioid therapies so desperate for relief that they’re turning to illicit drugs? That’s possible, but the study doesn’t address that specifically.

Another possibility is that patients on opioids are simply being more cautious and careful about their drug use. Opioid prescribing in the U.S. has fallen by 48% over the past five years, with many patients being forcibly tapered or abandoned by doctors who feel pressured to reduce their prescribing.  

“Unfortunately, a lot of people with chronic pain have learned that it’s a bit tenuous, that their doctors are feeling pressure, and if they want to maintain their access (to opioids), they need their PDMP (Prescription Drug Monitoring Program) and their drug tests to look the way they need to look, so their doctor can feel comfortable continuing to prescribe,” said co-author Steven Passik, PhD, VP of Scientific Affairs and Head of Clinical Data Programs at Millennium. “I do think they realize that they’re on a treatment and that access to it is not guaranteed.”   

Preliminary findings from the study were released today at PainWeek, an annual conference for pain management providers. The findings mirror those from another Millennium study earlier this year, which found that pain patients have lower rates of illicit drug use than patients being treated by other providers.     

“If your main way of protecting people in pain from getting involved in substance abuse is to limit their access to opioids, there’s at least a hint here that’s not the right approach,” Passik told PNN. “It’s not a definitive statement by any stretch of the imagination, but it’s an approach to patient safety that leaves a bit to be desired.”  

Another recent study at the University of Texas also found that restricting access to opioids is “not a panacea” and may even lead to more overdoses.  Researchers found that in states that mandated PDMP use, opioid prescribing decreased as intended, but heroin overdose deaths rose 50 percent.

“Past research has shown that when facing restricted access to addictive substances, individuals simply seek out alternatives rather than limiting consumption,” said lead author Tongil Kim, PhD, an assistant professor of marketing at University of Texas at Dallas. “In our case, we measured overdose deaths as a proxy and found a substantial increase, suggesting that the policy unintentionally spurred greater substitution.”

Pain Patients Have Low Rates of Illicit Drug Use

By Pat Anson, PNN Editor

Anti-opioid activists have long claimed that opioid medication is a gateway drug to heroin and other street drugs. That myth is so ingrained in the medical community that many pain patients are discriminated against by doctors and pharmacists, who suspect they are abusing their medication or using illicit drugs.

But a large new study by Millennium Health pokes a hole in that myth, finding that patients being treated in pain management practices are far less likely to use heroin, fentanyl, cocaine and methamphetamine than other patients.

The drug testing firm analyzed the lab results of two million urine tests from 2015 to 2021 – nearly 600,000 coming from pain patients -- and found that patients seeing primary care physicians, behavioral health doctors (psychiatrists and psychologists), or getting substance use disorder (SUD) treatment were significantly more likely to test positive for street drugs than patients of pain management providers.

SOURCE: MILLENNIUM HEALTH

“That’s one of the reasons why we decided to put this out there in the public domain, because it’s important. Because clearly there are differences across these groups,” said Eric Dawson, PharmD, Vice President of Clinical Affairs at Millennium Health.

For example, the positivity rate for fentanyl in urine samples is about 2% for pain management patients – a level that remained stable throughout the 6-year study period.

But Millennium found that for primary care and behavioral health patients, the positivity rate for fentanyl has ticked up to about 5 percent.

In patients getting SUD treatment, the positivity rate has skyrocketed to about 17 percent, no doubt a reflection of the growing presence of illicit fentanyl in street drugs.

Positivity rates for methamphetamine are also rising for most patients – but not for pain patients – while cocaine use has remained relatively flat. Positivity rates for heroin have declined steadily for all patients since 2015, according to Millennium.

“Generally speaking, the pain population that’s treated with opioids is an older population and uses illicit drugs at a very low rate,” said Steven Passik, PhD, VP of Scientific Affairs and Head of Clinical Data Programs at Millennium.

“Not only are they low, they remain low,” says Dawson. “So many of the other groups, over time their positivity rates are increasing. The pain population started low and remains low. And that says they are different than the other groups.”

What makes the findings even more striking is that they include the first two years of the covid pandemic, a time when stress, isolation and depression led many people to abuse drugs.

“But that did not happen in the pain patients. You can actually see that,” says Passik, who believes regular drug testing makes pain management patients less likely to take risks that might affect their healthcare. He thinks the Millennium study should be reviewed by both providers and policymakers to get a better understanding of people in pain.

“There isn’t that much data like this out there. I think it’s unique and very positive about this population. And I think that should be factored in when people are talking about access to opioids,” Passik told PNN.

In addition to fentanyl, heroin and other street drugs, the Millennium study also looked at positivity rates for marijuana, which have soared in recent years due to the legalization of medical and recreational cannabis in many states. By the end of 2021, the positivity rate for cannabis had reached nearly 32 percent for most patients. But, like the other drugs, cannabis use remained relatively low for pain patients.  

Focus on Opioid Crisis Overlooks Rise in Stimulant Deaths

By Pat Anson, PNN Editor

While much of the nation was focused on the opioid crisis, new research shows that another drug epidemic was taking the lives of U.S. military veterans.

University of Michigan researchers say the rate of veteran overdose deaths involving cocaine, methamphetamine and other stimulants tripled from 2012 to 2018. Most of the veterans did not receive any substance abuse treatment in the year before they died.

“We have been so focused on opioids that we are missing the tremendous increase in people who are using multiple substances, as well as those using stimulants only, when we know that many people don’t stick to just one substance,” says lead author Lara Coughlin, PhD, a psychologist and an assistant professor in the U-M Department of Psychiatry. “The fact that so many of those who died of an overdose had not received substance use disorder treatment is especially concerning.”

Coughlin and her colleagues reviewed the medical records of 3,631 veterans who died from overdoses involving stimulants, and found that about two-thirds of the deaths involved cocaine. Over half of the stimulant deaths (54.1%) also involved another substance, usually alcohol or an illicit opioid such as heroin or fentanyl. Prescription opioids were involved in less than 26% of the stimulant-related overdoses.

Researchers called the tripling of stimulant deaths “an escalating public health crisis” that deserves more attention.

“Recent trends show stark increases in stimulant-involved overdoses, with the majority of these overdoses deaths involving multiple classes of substances. These more complex, polysubstance-involved overdose deaths necessitate an expansion from a singular opioid-centric focus to include other substances and consideration of the role of stimulant use on overdose risk to inform effective prevention and treatment efforts,” researchers reported in the journal Addiction.

The authors noted there are few medication-based treatments to help people reduce their use of methamphetamine or cocaine, while multiple medications are available to treat those with opioid or alcohol use disorders.

Better access to treatment was especially needed for veterans in rural areas and those who are homeless. About one-third of all the overdose deaths involving stimulants were in Black veterans, as were two-thirds of the deaths from cocaine alone.

In addition to the risk of overdose, researchers say people who use methamphetamine or cocaine are at greater risk of heart damage. About 62% of the overdoses involving stimulants were among veterans aged 45 to 64.

“We need to build better awareness of the role of stimulants as a risk factor for overdose, and of the need for those who have stimulant use disorders to be referred for treatment, regardless if they are also using opioids,” said Coughlin. “We know that cocaine and methamphetamine are much more likely to be adulterated with fentanyl or other synthetic opioids now, so those who use them need to be equipped with rescue doses of naloxone to use and need to know about the risk for overdose in case they or someone they’re with experiences an unexpected, life-threatening reaction.”

The rise in stimulant deaths has not occurred in a vacuum. In the first half of 2019, data from 24 states and the District of Columbia showed that stimulants were involved in 5 out of 11 fatal overdoses. The CDC issued a Health Alert Network Advisory last year about a record number of overdoses, due in part to an acceleration in stimulant-related deaths.

Alcohol Deaths Double in U.S.

By Pat Anson, PNN Editor

Alcohol related deaths in the U.S. have doubled in the past two decades, according to a new study that highlights an under-reported aspect of the overdose crisis: while deaths involving prescription opioids are declining, alcohol abuse appears to be increasing.

Researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) found the number of death certificates mentioning alcohol more than doubled from 35,914 in 1999 to 72,558 in 2017.

By comparison, 17,029 deaths in 2017 involved a prescription opioid, according to CDC estimates.

“The current findings suggest that alcohol-related deaths involving injuries, overdoses and chronic diseases are increasing across a wide swath of the population. The report is a wakeup call to the growing threat alcohol poses to public health,” said NIAAA Director Dr. George Koob.

Nearly 1 million alcohol-related deaths were recorded between 1999-2017. About half the deaths resulted from chronic liver disease or overdoses on alcohol alone or with other drugs.

Researchers noted that alcohol-related deaths were increasing among people in almost every age, race and ethnic group. Their study is published in Alcoholism: Clinical & Experimental Research.

“Taken together, the findings of this study and others suggests that alcohol-related harms are increasing at multiple levels – from ED visits and hospitalizations to deaths. We know that the contribution of alcohol often fails to make it onto death certificates. Better surveillance of alcohol involvement in mortality is essential in order to better understand and address the impact of alcohol on public health,” said Koob.

Other drugs besides alcohol are increasingly involved in overdoses. A recent analysis of over one million urine drug tests conducted by Millennium Health found that positive results for illicit fentanyl rose by 333% since 2013, while positive rates for methamphetamine increased by 486 percent.

That study, published in JAMA Network Open, found that positive rates for heroin and cocaine peaked in 2016 and appear to be declining.

The analysis is similar to a 2019 report from the National Institute on Drug Abuse, which found that drug deaths involving prescription opioids and heroin have plateaued, while overdoses involving methamphetamine, cocaine and benzodiazepines have risen sharply.

Unreliable Data

Just how reliable is the federal data on drug use and overdoses? Not very, according to another study published in Drug and Alcohol Dependence.

Troy Quast, PhD, an associate professor at the University of Florida’s College of Public Health, compared overdose data from the Florida Medical Examiners Commission (FMEC) to drug deaths in a CDC database. Quast found the federal data significantly undercounted overdose deaths in Florida linked to cocaine, benzodiazepines, amphetamines and other drugs.

Florida medical examiners are required by law to wait for complete toxicology results before submitting an official cause of death to FMEC. It often takes weeks or months to identify the exact drug or drugs that cause an overdose. By contrast, the CDC data is based on death certificates filed by coroners and other local authorities, which often don't include detailed toxicology reports. This causes significant differences between the two databases.

Between 2003 and 2017, roughly one-in-three overdose deaths in Florida involving illicit or prescription opioids were not reported by the federal government. The discrepancy wasn’t limited to opioids. Quast also found that nearly 3,000 deaths in Florida caused by cocaine were not included in the CDC database. Overdose deaths involving benzodiazepines and amphetamines were also significantly under-reported.

"The CDC data are widely reported in the news and referenced by politicians, which is problematic since those estimates significantly undercount the true scope of the epidemic for specific drugs," said Quast. "The rate of under-reporting for all overdose deaths in Florida is near the national average, so the problem is not to the state."

This isn’t the first time the reliability of CDC data has been questioned. In 2018, CDC researchers admitted that many overdoses involving illicit fentanyl and other synthetic black market opioids were erroneously counted as prescription drug deaths. As result, federal estimates prior to 2017 "significantly inflate estimates" of prescription opioid deaths.

Even the adjusted estimates are imprecise, because the number of deaths involving diverted prescriptions or counterfeit drugs is unknown and drugs are not identified on 20% of death certificates. When the drugs are listed, many overdoses are counted multiple times by the government because more than one substance is involved.

The federal government is working to improve the collection of overdose data. Over 30 states are now enrolled in the CDC's Enhanced State Opioid Overdose Surveillance program, which seeks to improve overdose data by including toxicology reports and hospital billing records.

In 2017, the program reported that nearly 59 percent of overdose deaths involved illicit opioids like fentanyl and heroin, while 18.5% had both illicit and prescription opioids. Less than 18% tested positive for prescription opioids only.

A recent study of drug deaths in Massachusetts found that only 1.3% of overdose victims who died from an opioid painkiller had an active prescription for the drug – meaning the medication was probably diverted, stolen or bought on the street.  

The Overdose Crisis Is Not Just About Rx Opioids

By Roger Chriss, PNN Columnist

The CDC last week released its latest report on drug overdoses in 2017.  The death toll was the highest recorded, with over 70,000 Americans dying from drug poisoning. Deaths involving illicit fentanyl and other black market synthetic opioids surged 45 percent, while deaths involving opioid pain medication remained unchanged.

Although the death toll for 2018 may be a bit lower, it is premature to declare as the Washington Post did that “the opioid epidemic may be receding.”

Instead, the crisis is evolving.

“Fentanyl deaths are up, a 45 percent increase; that is not a success,” Dan Ciccarone, PhD, a professor at the University of California, San Francisco, told the New York Times. “We have a heroin and synthetic opioid epidemic that is out of control and needs to be addressed.”

The available data for 2018 supports this. There have been over 1,500 overdoses in Massachusetts so far this year and the details of those deaths are sobering. Fentanyl was present in 90 percent of toxicology reports during the second quarter of 2018, a three-fold increase since 2014. Prescription drugs of any form were found in only 17 percent of reports.

Public health data from Connecticut is similar. Illicit opioids were found in nearly 80 percent of the 867 people who died of an unintentional opioid overdose in 2016.

Current data is also showing that drugs like methamphetamine are having a significant impact on overdose rates. Kaiser Health News reports that amphetamine related hospitalizations – mostly involving meth – are surging and that more than 10,000 people died of meth-related drug overdoses last year.

The opioid overdose crisis is no longer primarily about prescription opioids used medically, or even exclusively about opioids. And studies of long-term opioid therapy are not showing increasing rates of overdose.

Medscape reported on a recent study that found cancer patients had a much lower risk of dying from an opioid overdose than the general population. The study looked at opioid deaths from 2006 through 2016, a period that saw rapidly rising overdose rates. Opioid death rates jumped from 5.33 to 8.97 per 100,000 people in the general population during that period, but among cancer patients, opioid deaths rose from 0.52 to 0.66 per 100,000.

Another recent study found that the use of opioids in treating pain from sickle cell disease was “safe” and rarely results in overdoses  

“What our study uniquely shows is that, using this large nationwide database, that deaths in a hospital setting related to opioid toxicity or overdose almost never happen among those with sickle cell disease," Oladimeji Akinola Akinboro, MBBS, of Boston University School of Medicine told Medpage. "This suggests that current patterns of opioid use in this population is safe, assuming we continue the same risk-mitigation strategies."

In other words, long-term pain management in disorders like cancer and sickle cell disease is not associated with increased rates of fatal overdose. Both of these studies have important limitations, in particular the possibility that some overdose deaths went uncounted. But the low rates of overdose in these groups suggests that with careful patient screening and monitoring, opioids can be used safely.

More can and should be done. Opioids are being prescribed more cautiously to children and teens. This is important, in light of a new JAMA study on wisdom tooth extraction, which found that over 5% of young people who had their wisdom teeth removed and received opioids for pain control went on to receive an opioid abuse-related diagnosis.

The overdose crisis is fast evolving into a poly-drug substance use problem. Addiction expert Michael Botticelli, the former director of National Drug Control Policy, told WBUR that a better understanding is needed of why people use drugs, not just which drugs they use.

"The data are pretty clear that we have a drug use epidemic and a drug overdose epidemic,” he said. “I think we have to really be careful that our strategies speak to all of those issues.”

Lower Back Pain Linked to More Drug Use

By Pat Anson, Editor

People with chronic lower back pain are more likely to have used illicit drugs -- including marijuana, cocaine, heroin and methamphetamine -- compared to those without back pain, according to new research published in the journal Spine.

The study also found that people with lower back pain who had used illicit drugs were somewhat more likely to have an active prescription for opioid pain medication (22.5% vs. 15%).

Lower back pain is the world’s leading cause of disability and most people will suffer from it at least once in their lives. Although nearly a quarter of the opioid prescriptions written in the U.S. are for low back pain, medical guidelines often recommend against it.

Researchers analyzed data from over 5,000 U.S. adults who participated in a nationally representative health study and found that nearly half (49%) of those who reported lower back pain admitted having a history of illicit drug use, compared to 43% of those without back pain.

Current use of illicit drugs (within the past 30 days) was much lower in both groups; 14% versus nine percent.

The study did not differentiate between recreational and medical marijuana use, nor did it draw a distinction between marijuana use in states where it is legal and where it is not. All marijuana use was considered "illicit."

All four illicit drugs in the survey were more commonly used by people with low back pain compared to those without back pain. Rates of lifetime use were 46.5% versus 42% for marijuana; 22% vs. 14% for cocaine; 9% vs. 5% for methamphetamine; and 5% vs. 2% for heroin.

Researchers said there was no evidence that illicit drug use causes lower back pain, only that there was an association between the two that bears watching when opioids are prescribed.

“The association between a history of illicit drug use and prescription opioid use in the cLBP (chronic lower back pain) population is consistent with previous studies, but may be confounded by other clinical conditions,” said lead author Anna Shmagel, MD, Division of Rheumatic and Autoimmune Diseases at the University of Minnesota.

“Mental health disorders, for example, have been associated with both illicit substance use and prescription opioid use in the chronic low back pain population. In the context of management, however, illicit drug abuse is predictive of aberrant prescription opioid behaviors. As we face a prescription opioid addiction epidemic, careful assessment of illicit drug use history may aid prescribing decisions.”

In a recent analysis of prescriptions filled for 12 million of its members, pharmacy benefit manager Prime Therapeutics found that nearly a quarter of the opioid prescriptions were written to treat low back pain.

"Our analysis found low back pain was the most common diagnosis among all members taking an opioid, even though medical guidelines suggest the risks are likely greater than the benefits for these individuals," said Catherine Starner, PharmD, lead health researcher for Prime Therapeutics.

In a 2014 position paper, the American Academy of Neurology said opioids provide “significant short term pain relief” for low back pain, but there was “no substantial evidence” that long term use outweighs the risk of addiction and overdose.
