Is Cannabis Harmful During Pregnancy and Adolescence?

By Hilary Marusak, Wayne State University

Cannabis is a widely used psychoactive drug worldwide, and its popularity is growing: The U.S. market for recreational cannabis sales could surpass $72 billion by 2023.

As of early 2023, 21 U.S. states and the District of Columbia have legalized cannabis for recreational use for people age 21 and up, while 39 states plus the District of Columbia have legalized it for medical use.

The growing wave of legalization and the dramatic increase in cannabis potency over the past two decades have raised concerns among scientists and public health experts about the potential health effects of cannabis use during pregnancy and other vulnerable periods of development, such as the teen years.

I am a developmental neuroscientist specializing in studying what’s known as the endocannabinoid system. This is an evolutionarily ancient system found in humans and other vertebrates that produces natural cannabinoids such as THC and CBD.

Cannabis and its constituents interact with the body’s endocannabinoid system to product their effects. THC and CBD are the most commonly known cannabis extracts and can be synthesized in a lab. My lab also studies the risks versus potential therapeutic value of cannabis and cannabinoids.

Potential Health Risks

People often assume there’s no risk when using cannabis or cannabinoids during vulnerable periods of life, but they’re basing that on little to no data. Our research and that of others suggests that cannabis use during pregnancy and adolescence can present myriad health risks the public should be aware of.

Data shows that many people who use cannabis continue to do so during pregnancy. But there are health risks. More and more pregnant people are using cannabis today compared with a decade ago, with some studies showing that nearly 1 in 4 pregnant adolescents report that they use cannabis.

Many cannabis-using people may have not known they were pregnant and stopped using when they found out. Others report using cannabis for its touted ability to ease pregnancy-related symptoms, like nausea and anxiety. However, studies do not yet confirm those health claims. What’s more, the potential harms are often downplayed by pro-cannabis marketing and messaging by dispensaries, advocacy groups and even midwives or doulas.

In addition, physicians and other health care providers often are not knowledgeable enough or don’t feel well equipped to discuss the potential risks and benefits of cannabis with their patients, including during pregnancy.

While research shows that most people who are pregnant perceive little to no risk in using cannabis during pregnancy, the data show there is clear cause for concern. Indeed, a growing number of studies link prenatal cannabis exposure to greater risk of preterm birth, lower birth weight and psychiatric and behavioral problems in children. These include, for example, difficulties with attention, thought, social problems, anxiety and depression.

Cannabis and Brain Development

When cannabis is inhaled, consumed orally or taken in through other routes, it can easily cross through the placenta and deposit in the fetal brain, disrupting brain development.

A recent study from my lab, led by medical student Mohammed Faraj, found that cannabis use during pregnancy can shape the developing brain in ways that are detectable even a decade later.

We used data from the National Institutes of Health Adolescent Brain Cognitive Development Study, which is the largest long-term study of brain development and child and adolescent health in the U.S. It has followed more than 10,000 children and their families from age 9-10 over a 10-year period.

Through that analysis, we linked prenatal cannabis exposure to alterations in functional brain networks in 9- and 10-year-old children. In particular, prenatal cannabis exposure appeared to disrupt the communication between brain networks involved in attentional control, which may explain why children who were exposed to cannabis in utero may develop difficulties with attention or other behavioral issues or mental disorders as they develop.

While alcohol abuse has steadily declined among adolescents since 2000 in the U.S., cannabis use shows the opposite pattern: It increased by 245% during that same period.

Data reported in 2022 from the Monitoring the Future survey of over 50,000 students in the U.S. found that nearly one-third of 12th grade students reported using cannabis in the past year, including cannabis vaping. Yet only about 1 in 4 12th grade students perceive great harm in using cannabis regularly. This suggests that many teens use cannabis, but very few consider it to have potential negative effects.

Research shows that the adolescent brain is primed to engage in high-risk behaviors such as experimenting with cannabis and other substances. Unfortunately, owing to ongoing brain development, the adolescent brain is also particularly susceptible to the effects of cannabis and other substances. Indeed, many neuroscientists now agree that the brain continues to develop well into the second and even third decade of life.

In line with this vulnerability, research shows that, relative to those who did not use cannabis during adolescence, those who started using it during adolescence are at increased risk of developing depression, suicidal ideation, psychosis and reductions in IQ during adolescence and adulthood. Neuroimaging studies also show residual effects of adolescent cannabis use on brain functioning, even later during adulthood.

‘No Amount Is Safe’

Despite common misconceptions that cannabis is “all natural” and safe to use during pregnancy or adolescence, the data suggests there are real risks. In fact, in 2019, the U.S. surgeon general issued an advisory against the use of cannabis during pregnancy and adolescence, stating that “no amount … is known to be safe.”

Cannabis may be harmful to the developing brain because it disrupts the developing endocannabinoid system, which plays a critical role in shaping brain development from conception and into adulthood. This includes neural circuits involved in learning, memory, decision-making and emotion regulation.

While much of this research has focused on cannabis use, there is also other research that comes to similar conclusions for THC and CBD in other forms. In fact, although CBD is widely available as an unregulated supplement, we researchers know almost nothing about its effects on the developing brain. Of note, these harms apply not only to smoking, but also to ingesting, vaping or other ways of consuming cannabis or its extracts.

In my view, it’s important that consumers know these risks and recognize that not everything claimed in a label is backed by science. So before you pick up that edible or vape pen for stress, anxiety, or sleep or pain control, it’s important to talk to a health care provider about potential risks – especially if you are or could be pregnant or are a teen or young adult.

Medical Gaslighting of Woman for Being of 'Childbearing Age' Goes Viral

By Madora Pennington, PNN Columnist

After seeing a neurologist earlier this month for cluster headaches, Tara Rule’s doctor walked her to the front desk. She thanked him. Then, in her car, she burst into tears. Instead of treating her pain, the doctor turned the appointment into a lecture about a hypothetical pregnancy that she didn't want. He had made her feel so horrible, she wanted to die.

“I can’t keep living in world where it is a game to them,” she said to herself.

Feeling hopeless and alone, Rule pulled out her cellphone and, tears streaming down her face, recorded a video recounting what had just happened and how she felt about it.

It is rare to actually see the raw, visceral reaction to medical gaslighting, and how it affects someone’s self-worth and mental health. Many patients leave such appointments doubting themselves, often becoming unwilling to seek medical care as the medical traumas add up.

Rule, 31, is already on disability from a lifetime of complex medical problems, including Ehlers-Danlos Syndrome (EDS), a connective tissue disorder.

When she realized her appointment at a Glen Falls, New York hospital was going sideways, she reached into her bag and began an audio recording with her cellphone. New York allows single party consent to recording, so she didn't need to have the doctor’s permission.

Rule was trying to keep it together, despite her intense pain from debilitating headaches. She wanted the recording so she could sort out what happened later. She wanted to make sure her PTSD from past medical trauma was not triggering her, possibly causing her to misunderstand the doctor.

TARA RULE

In the recording, Rule’s neurologist said he would not give her a certain medication to treat her headache. His reason? She could get pregnant and that particular drug — which he did not name — can cause birth defects. So he doesn't prescribe it to women of "childbearing age."

Rule pushed back, pointing out she is already on a medication for an autoimmune condition that can cause birth defects and miscarriages. And because EDS is a genetic disorder, she does not want to have a child and risk passing it on. Plus, a pregnancy could be harmful for her health.

Instead of making the appointment about Rule's pain and her need for treatment, she says the doctor asked her intrusive questions about her sex life. He disregarded the medical information she provided and patronizingly suggested she might change her mind if she were pregnant. He also insisted her sexual partner would have to consent to her being treated with the unnamed drug.

Rule posted her anguished video on TikTok, and it soon went viral. She's received countless messages from others who have been through similar encounters. While it made her feel less alone, it saddened Rule deeply to learn how many people have stories like hers. The media took notice with articles on Jezebel and in the Albany Times Union.

Severe headaches and cranio-cervical pain are commonly seen in people with EDS, an inherited failure of the body to produce strong collagen. Rule has suffered from migraines since she got a concussion at age eight. Her cluster headaches started in 2016.

“They are a whole different beast,” she told me. “The pain is indescribable. It doesn’t let up. It won’t go away.” Rule says she is a happy person who is not suicidal, but pain like that makes you wish you weren’t alive.

Rather than treat the suffering patient in front of him, the neurologist prioritized a hypothetical situation, in which Rule's birth control fails and she winds up pregnant. For him, this fantasy scenario was more important than giving her the best medical option for pain relief.

Rule complained to the hospital, which apologized and began an investigation. She also created a petition to end doctors' ability to deny treatment to women because they might get pregnant. So far, over 25,000 people have signed it, making it one of the most popular petitions on Change.org.

“As a living, breathing human being who exists, I feel it is absurd that doctors who are expected to provide the best, most effective care and treatments to their patients are able to deny effective treatments due to the potential for birth defects in patients of child bearing age who are not currently pregnant,” she wrote in the petition. 

The week after her botched meeting with the neurologist, Rule found herself in throes of horrendous head pain and took herself to urgent care. She was receiving an IV and oxygen when a group of doctors and security personnel marched into her room. She panicked, thinking of when she was told she had lesions on her brain. Were these people coming to give her bad news like that?

No, the staff was not here to provide medical services. They had come to discharge her. The hospital Rule had complained to apparently called other clinics in the area about her. The urgent care personnel accused her of livestreaming the appointment with her neurologist, which she did not. Nonetheless, they wanted her out immediately. She tried to give the desk her new insurance information as she left, but the staff had closed the window and simply stared at her.

“Shouldn’t they be putting that doctor on leave rather than track my social media and call hospitals? It’s scary,” she told PNN.

Now Rule is afraid to seek medical care. Most of the facilities in her area are owned by that hospital system. Her primary care doctor is part of it. She is not sure if any of them will see her.

“I’m on disability. I have no money. Am I going to have to move?” she wonders.

Early Use of Methotrexate Slows Rheumatoid Arthritis

By Pat Anson, PNN Editor

Early treatment with methotrexate can significantly reduce joint pain and inflammation in patients showing early signs of rheumatoid arthritis (RA), according to a new study by Dutch researchers.

First used as a chemotherapy treatment because it prevents cancer cells from dividing, methotrexate became a first-line therapy for RA in the 1980’s because it also acts as an immune system inhibitor. RA is a chronic autoimmune disease in which the body’s own defenses attack joint tissues, causing pain, swelling, inflammation and bone erosion. 

Treatment with methotrexate usually isn’t initiated until RA is diagnosed, but researchers at Leiden University Medical Centre (LUMC) in the Netherlands found that early treatment of patients in the "pre-rheumatic phase" helped slow progression of the disease.

"At present, methotrexate is only prescribed to the patient following a rheumatoid arthritis diagnosis," said lead author Annette van der Helm, PhD, Professor of Rheumatology at LUMC. "But that is too late. By then, the disease is already considered chronic."

Van der Helm and her colleagues enrolled 236 patients who had joint pain and inflammation that could be seen on an MRI. Although RA was suspected, it was not yet confirmed. Half the patients were treated with methotrexate and the other half with a placebo. The effects of the treatments were assessed a year later.

The study findings, published in The Lancet, show that early treatment with methotrexate did not prevent the development of RA, but the diagnosis was delayed. Patients in the methotrexate group also had less pain and morning stiffness than those treated with a placebo. Their physical function was also better and their MRI scans showed less joint inflammation.

"This is an important step towards reducing disease burden for this group of patients," says Van der Helm. "This chronic disease is extremely burdensome to patients and their families. Our study is paving the way toward arthritis prevention."

In 2019, over a million people were prescribed methotrexate in the United States, where it is approved as a treatment for RA, psoriasis and cancer. The drug is also used “off-label” for lupus, migraine, multiple sclerosis, Crohn’s Disease and other autoimmune problems.   

‘Abortion-Inducing Drug’

Ironically, the Dutch study comes at a time when some female patients in the U.S. are losing access to methotrexate because the drug can cause miscarriages and be used to end ectopic pregnancies. After last month’s Supreme Court ruling that overturned Roe vs. Wade, over half the states enacted or implemented abortion limits, including some that specifically list methotrexate as an “abortion-inducing drug.”  

Although the state laws don’t prohibit methotrexate from being used for other purposes, some doctors, pharmacies and insurers have become cautious about prescribing or dispensing the drug. The Arthritis Foundation has heard from several women who’ve had trouble getting methotrexate, including some beyond childbearing age.

“Some of the stories we’ve gotten in are of women who are over the age of 50 — they are past their reproductive years — and they’re still being asked really invasive questions and having roadblocks thrown up,” Dr. Anna Hyde of the Arthritis Foundation told NBC4 in Washington.

Up to 90% of RA patients are prescribed methotrexate at some point. It doesn’t work for everyone and can have side effects, but it’s the only affordable option for many patients, costing about $50 for a month’s supply of generic methotrexate tablets. Other treatments for RA, such as disease modifying biologic drugs, can cost as much as $3,000 a month and are not covered by insurance.  

Pregnant Women Raise Risk of Complications by Using OTC Pain Relievers

By Pat Anson, PNN Editor

Pregnant women who take over-the-counter pain relievers are one-and-a-half times more likely to have complications, including stillbirth and premature delivery, according to a large new study.

Researchers at the University of Aberdeen analyzed data from over 151,000 pregnancies in the UK from 1985-2015, looking for medical notes indicating the women used paracetamol (acetaminophen), aspirin or the non-steroidal anti-inflammatory drugs (NSAIDs) diclofenac, naproxen and ibuprofen — either alone or in combinations.

The findings, recently published in BMJ Open, show a significantly higher risk of a preterm delivery, neonatal death, low birth weight and other health problems in babies born to mothers who used OTC pain relievers. Neural tube defects of the brain, spine or spinal cord were 64% more likely; while hypospadias, a birth defect affecting the penis, was 27% more likely.

“Over-the-counter analgesics consumption during pregnancy was associated with a substantially higher risk for adverse perinatal health outcomes in the offspring. The use of paracetamol in combination with other non-steroidal anti-inflammatory drugs conferred the highest risk,” wrote lead author Aikaterini Zafeiri, PhD. “The increased risks of adverse neonatal outcomes associated with non-prescribed, over-the-counter, analgesics use during pregnancy indicate that healthcare guidance for pregnant women regarding analgesic use need urgent updating.”

One of the more surprising aspects of the study is how use of the five analgesics by pregnant women grew dramatically over the 30-year study period.  In 1985, only 1.8% reported using one of the pain relievers. By 2015, that had grown to 70.6% -- with most of the increase coming in the last seven years of the study.

Although it is believed to be one of the largest and most comprehensive studies of its kind, the research was limited. The duration, dose and stage of the pregnancy when analgesics were consumed were not recorded. The health of the mothers and babies later in life was also not studied.

But given the substantial increase in analgesic use during pregnancy and the higher risk of complications, researchers say more caution is needed on use of the drugs.

“The ease of access to non-prescription painkillers, in combination with availability of misinformation as well as correct information through the internet, raises safety concerns,” said Zafeiri. “It should be reinforced that paracetamol in combination with NSAIDs is associated with a higher risk and pregnant women should always consult their doctor or midwife before taking any over-the-counter drugs. We would encourage a strong reinforcement of the official advice for pregnant women.”   

Previous studies have linked prenatal use of paracetamol to autism, hyperactivity and behavioral problem in children. Despite the findings, drug regulators in the UK and US maintain that it is safe for pregnant women to use paracetamol (acetaminophen).

“Paracetamol is the first choice of painkiller if you're pregnant or breastfeeding. It's been taken by many pregnant and breastfeeding women with no harmful effects in the mother or baby,” the UK’s National Health Service (NHS) says on its website.

The Food and Drug Administration also does not caution pregnant women about using acetaminophen. The agency said in 2015 that the evidence was “too limited” to justify such a warning.  

Meanwhile, drug regulators in Australia are so concerned about recent deaths involving paracetamol that they may restrict access to the drug. Australia’s Therapeutic Goods Administration (TGA) has commissioned a report by an expert panel on the risks of paracetamol misuse.

“While paracetamol has well established safety and toxicity profiles, the wide use is paralleled by a high prevalence of accidental and deliberate paracetamol poisoning in the community, in both adults and children,” the TGA said in a statement earlier this month.

“The TGA is aware of concerns, particularly of families and healthcare professionals of affected consumers of paracetamol, regarding the number of poisonings and deliberate overdoses from paracetamol obtained from general retail outlets, and whether current access restrictions are appropriate.”

Australia currently regulates the quantity and dose of paracetamol sold over-the-counter. The independent commission will consider if stricter buying limits should be imposed. 

Prenatal Use of Acetaminophen Linked to Early Puberty

By Pat Anson, PNN Editor

The daughters of women who took acetaminophen during pregnancy tend to start puberty early, according to a new study by Danish researchers.  

The study is the latest indication that prenatal use of acetaminophen – more commonly known as paracetamol outside the U.S. -- can have long term effects on children.

Researchers at Aarhus University studied health data on about 100,000 Danish women who provided detailed information about their use of acetaminophen during pregnancy.

Nearly 16,000 children born to those mothers between 2000 and 2003 were followed from the age of eleven and throughout puberty, with surveys every six months about different aspects of their development.

The study, published in the American Journal of Epidemiology, found that girls on average entered puberty between one-and-a-half and three months earlier if their mothers took the over-the-counter pain reliever for more than 12 weeks during pregnancy.

"We found a 'dose-response' correlation. That is to say, the more weeks with paracetamol during pregnancy, the earlier puberty in girls, but not in boys," says lead author Andreas Ernst, a PhD student from the Department of Public Health at Aarhus University.

"While entering puberty one-and-a-half to three months earlier may seem unimportant, when taken together with the frequent use of paracetamol during pregnancy, our findings ought to make people take notice. Our results are certainly not the decisive factor that should change current practice, but the perception of paracetamol as 'the safe and harmless choice' during pregnancy ought to be challenged."

Early puberty development increases the risk of serious diseases in adulthood, such as obesity, diabetes, cardiovascular diseases and testicular and breast cancer.

The use of acetaminophen (paracetamol) has been increasing worldwide and studies have found that over half of pregnant women in the U.S. and European Union use the pain reliever at least once during their pregnancy. It is the active ingredient in Tylenol, Excedrin, and hundreds of pain medications.

Previous research has shown that prenatal use of acetaminophen is associated with slow language development, autism and attention deficit problems in young children.

Over 50 million people in the U.S. use acetaminophen each week to treat pain and fever. The pain reliever has long been associated with liver injury and allergic reactions such as skin rash. The FDA label for products containing acetaminophen warns about the risk of liver damage and other side effects but does not specifically warn pregnant women about using the pain reliever. The agency said in 2015 that the evidence was “too limited” to justify such a warning.  

In its 2016 opioid prescribing guidelines, the CDC recommends acetaminophen as an alternative to opioid pain medication. The guideline only briefly mentions that acetaminophen is involved in hundreds of overdose deaths annually and can cause liver problems.

The CDC guideline does warn pregnant women -- at length -- that opioids can cause birth defects, poor fetal growth, still births and neonatal opioid withdrawal syndrome.

Acetaminophen Linked to Kids’ Behavior Problems

By Pat Anson, Editor

Another study has linked acetaminophen to attention deficit and other behavioral problems in children whose mothers used the over-the-counter pain reliever while pregnant.

"Children exposed to acetaminophen use prenatally are at increased risk of multiple behavioral difficulties,” said lead author Evie Stergiakouli, PhD, of the University of Bristol. “Given the widespread use of acetaminophen among pregnant women, this can have important implications on public health advice.”

The study, published in JAMA Pediatrics, involved nearly 7,800 mothers in the UK who used acetaminophen in 1991 and 1992.

Prenatal use of acetaminophen in the second and third trimesters was associated with a higher risk of behavior problems and hyperactivity in children. Use of acetaminophen at 32 weeks of pregnancy was also associated with a higher risk for emotional problems.

“We found stronger association between maternal acetaminophen use and multiple behavioral and emotional problem domains during the third trimester than during the second trimester, in agreement with previous studies that have included multiple measurement times during pregnancy," said Stergiakouli. 

"Given that there is active brain development and growth during the third trimester, this finding could indicate that there are developmental periods when the brain is more sensitive to acetaminophen exposure.” 

Acetaminophen (paracetamol) is one of the most widely used pain relievers in the world. It is the active ingredient in Tylenol, Excedrin, and hundreds of other pain medications. Researchers say over half the pregnant women in the United States and European Union use the drug.

"The risk of not treating fever or pain during pregnancy should be carefully weighed against any potential harm of acetaminophen to the offspring," said Stergiakouli. 

A recent study of over 2,600 Spanish women linked acetaminophen to autism and attention deficit problems in their children. Studies in Denmark and New Zealand have also linked acetaminophen with a higher risk of hyperkinetic disorders and attention-deficit hyperactivity disorder (ADHD).

Over 50 million people in the U.S. use acetaminophen each week to treat pain and fever. The pain reliever has long been associated with liver injury and allergic reactions such as skin rash.

Lyrica Linked to Birth Defects

By Pat Anson, Editor

A drug widely prescribed to treat fibromyalgia, neuropathy and other chronic pain conditions increases the risk of major birth defects, according to a new study published in Neurology, the medical journal of the American Academy of Neurology.

Women taking pregabalin were six times more likely to have a pregnancy with a major defect than women who were not taking the drug, the study found. The birth defects included heart defects and structural problems with the central nervous system (CNS) or other organs. Birth defects due to chromosomal abnormalities were not included in the results.

Pregabalin is the generic name of Lyrica, which is approved by the FDA to treat diabetic nerve pain, fibromyalgia, epilepsy, post-herpetic neuralgia caused by shingles and spinal cord injury. It is also prescribed “off label” to treat a variety of other conditions. Lyrica is Pfizer’s top selling drug, generates over $5 billion in annual sales, and is currently approved for use in over 130 countries.

The international study involved nearly 700 pregnant women in seven different countries. Four of the 125 women who took pregabalin during pregnancy had children with central nervous system defects, or 3.2 percent. That compares to a birth defect rate of just 0.5% in the 570 women who did not take pregabalin.

Of the women taking pregabalin, 115 were taking it to treat neuropathic pain, 39 were taking it for psychiatric disorders, including depression and anxiety, five were taking it for epilepsy, and one for restless leg syndrome.

Most of the women started taking pregabalin before they became pregnant. All of them stopped taking the drug at an average of six weeks into their pregnancies.

A small number of women also took another anti-seizure drug during their pregnancy. Women in that group had a 6 percent chance of a major birth defect, compared to 2 percent of the women who did not take another anti-seizure medication.

“We can’t draw any definitive conclusions from this study, since many of the women were taking other drugs that could have played a role in the birth defects and because the study was small and the results need to be confirmed with larger studies, but these results do signal that there may be an increased risk for major birth defects after taking pregabalin during the first trimester of pregnancy,” said study author Ursula Winterfeld, PhD, of the Swiss Teratogen Information Service and Lausanne University Hospital in Lausanne, Switzerland.

“Pregabalin should be prescribed for women of child-bearing age only after making sure that the benefits of the drug outweigh the risks and after counseling them about using effective birth control. In cases where women have taken pregabalin during pregnancy, extra fetal monitoring may be warranted.”

A spokesman for Pfizer said the study was small and the findings could have been influenced by other factors.

"As the authors agree, the study has significant limitations and cannot be used to draw definitive conclusions," Steven Danehy said in an email to Pain News Network. "The study was small, did not account for other medical conditions or medications, and the women taking Lyrica had higher rates of smoking and diabetes, all of which can negatively affect pregnancy outcomes."  

Because women are more likely than men to have a chronic pain condition such as fibromyalgia, they are the biggest consumers of Lyrica.

The FDA warning label for Lyrica does not specifically warn pregnant women not to take the drug. But it does caution them to consult with a doctor if they are pregnant or plan to become pregnant.

“It is not known if Lyrica will harm your unborn baby. You and your healthcare provider will have to decide if you should take Lyrica while you are pregnant. If you become pregnant while taking Lyrica, talk to your healthcare provider about registering with the North American Antiepileptic Drug Pregnancy Registry,” the label says.

The label also cautions men to see a doctor if they plan to father a child while taking Lyrica. 

“Animal studies have shown that pregabalin, the active ingredient in Lyrica, made male animals less fertile and caused sperm to change. Also, in animal studies, birth defects were seen in the offspring (babies) of male animals treated with pregabalin. It is not known if these problems can happen in people who take Lyrica,” the warning label states.

CDC Reports on Opioids Appear Biased

By Lynn Webster, MD, Guest Columnist

Like most people, I respect the opinion of the Centers for Disease Control and Prevention (CDC). It is our first and last line of defense against everything from chronic disease to full-fledged pandemics. That said, I am perplexed why the CDC would sound an alarm, while at the same time acknowledging that the fire doesn’t actually exist.

That’s more or less what the CDC did in a report finding that approximately a quarter of privately insured and a third of Medicaid-enrolled women of reproductive age (15-44 years) filled a prescription for an opioid each year from 2008 to 2012. The report went on to say that the trend of opioid prescriptions among childbearing women places unborn children at risk for birth defects. On this point, the report does not address how many of the women actually became pregnant and otherwise has a glaring absence of empirical data to support its claims.

If you are a clinician or scientist, the CDC report appears incomplete and biased against people in pain. If you are a patient or consumer of the news, the report is alarming. Neither of these outcomes advances medicine, nor do they help people who abuse prescription medication or those who experience chronic pain.

Without question, opioids must be replaced as a primary method of pain treatment in favor of safer and more effective therapies. It is clear that in many instances, the risks of opioid therapy far outweigh the benefits. However, many patients with pain have no other options, so until patients have access to effective alternatives, this type of reporting is counterproductive.

Because the report does not clarify the actual risks, nor compare them with the risks of continued pain in the absence of treatment, the CDC wades into dangerous territory of conjecture. Moreover, an overreliance on retrospective observational studies makes it difficult to evaluate the true impact of opioid use on the incidence of birth defects or whether other factors, such as the mother’s health status and co-occurring tobacco or alcohol use, were greater contributors. Although neonatal abstinence syndrome can definitely be traced to opioid use, the CDC investigators did not examine why the majority of infants born to opioid-consuming mothers do not develop it.

In addition to fuzzy reporting of the science, ethical issues are apparent in considering all women of childbearing age as fundamentally “prepregnant” when it comes to clinical decision making regarding opioid analgesia. These concerns were well delineated by Kristen Gwynne in an online article at RH Reality Check. Clinicians must always weigh potential benefits against potential harm before prescribing opioid therapy. But this has always been true of opioids and all medications, including nonsteroidal anti-inflammatory drugs, antidepressants and anticonvulsants.

The result of incomplete reporting could be the withholding of opioids from people based on gender and age, regardless of pregnancy status, even when strong pain-killing medications are indicated or when safer alternatives are not available. In fact, according to the American Congress of Obstetricians and Gynecologists, “Abrupt discontinuation of opioids in an opioid-dependent pregnant woman can result in preterm labor, fetal distress, or fetal demise.”

To be viable, alternatives to opioids must be effective and be covered by public and private insurance payers. Commentators who suggest opioids should not be prescribed often fail to present this important perspective and also imply that harm from opioids is inevitable, an error that contributes to the stigma and isolation felt by those whose lives would be crippled without their legally prescribed medications.

And yet, slanted reporting continues. In February, another CDC report appeared, endorsing scientifically vague opioid classifications of “stronger vs. weaker” than morphine. In analyzing the February report, June Dahl, PhD, properly pointed out the error in failing to consider the differing pharmacologic factors, mechanisms of action, formulations and the clinical relevance of relative effectiveness when comparing the medications.

Given the concerns with accuracy of scientific reporting, is it reasonable to increase federal funding to the CDC to battle prescription opioid abuse, as requested? Only with an understanding of the real reasons for the current opioid problem can we solve the problem. Perhaps more dollars should instead go to the National Institutes of Health, which is in desperate need of more funding for pain research and to develop safer alternatives to opioids.

Regardless, solutions cannot succeed in the absence of recognition that uncontrolled chronic pain is a major public health problem, worthy of focus similar to efforts to battle cancer, HIV/AIDS and other life-threatening diseases. Education of clinicians is good but cannot create treatment options or adequate insurance coverage where none exist. CDC officials and others must think about the problem differently and with less prejudice against people with chronic pain. Often the focus is on cutting supply alone; but in reality, this is difficult to accomplish without harming people with genuine pain when the payor system does not adequately cover evidence-based alternative therapies, including multidisciplinary integrative programs.

Instead payors, particularly government programs such as the Centers for Medicare & Medicaid Services and workers’ compensation, prefer the less costly opioid methadone, associated with more fatalities per prescription than any other.

Although a majority of opioid-prescribed patients do not abuse or become addicted, it is undoubtedly true that some people have contraindications for long-term prescribed opioids. These are potentially dangerous medications, which can be fatal. But effective solutions require a multifaceted approach and cannot ignore the needs of people in pain. Opioids formulated with abuse deterrents are needed as is greater funding and less stigmatization of people with the disease of addiction. Certainly, payors should cover safer and more effective therapies.

As I’ve said before, I hope opioids will one day not be needed, and commentaries like this one will be unnecessary. If the public health problem from opioids is too great, then it is the purview of the CDC to report on access to safer and more effective therapies in the interest of the other great public health problem: chronic pain. It is not an option to deny people in pain access to opioids if alternatives are nonexistent or unavailable.
