Tackling Complex Scientific Questions Requires a Team Approach
Posted on by Nora D. Volkow, M.D., National Institute on Drug Abuse
During the COVID-19 pandemic, we have seen unprecedented, rapid scientific collaboration, as experts around the world in discrete, previously disconnected fields, have found ways to collaborate to face a common cause. For example, physicists helped respiratory specialists understand how virus particles could spread in air, leading to improved mitigation strategies. Specialists in cardiovascular science, neuroscience, immunology, and other fields are now working together to understand and address Long COVID. Over the past two years, we have also seen remarkable international sharing of epidemiological data and information on effects of vaccines.
Science is increasingly a team activity, which is true for many fields, not just biomedicine. The professional diversity of research teams reflects the increased complexity of the questions science is called upon to answer. This is especially obvious in the study of the brain, which is the most complex system known to us.
The NIH’s Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative, with the goal of vastly enhancing neuroscience through new technologies, includes research teams with neuroscientists, engineers, mathematicians, physicists, data scientists, ethicists, and more. Nearly half (47 percent) of grant awards have multiple principal investigators.
Besides the BRAIN Initiative, other multi-institute NIH research projects are applying team science to complex research questions, such as those related to neurodevelopment, addiction, and pain. The Helping to End Addiction Long-term® Initiative, or NIH HEAL Initiative®, created a team-based research framework to advance promising pain therapeutics quickly to clinical testing.
In the Adolescent Brain Cognitive Development (ABCD) study, which is led by NIDA in close partnership with NIH’s National Institute on Alcohol Abuse and Alcoholism (NIAAA), and other NIH institutes, 21 research centers are collecting behavioral, biospecimen, and neuroimaging data from 11,878 children from age 10 through their teens. Teams led by experts in adolescent psychiatry, developmental psychology, and pediatrics interview participants and their families. These experts then gather a battery of health metrics from psychological, cognitive, sociocultural, and physical assessments, including collection and analysis of various kinds of biospecimens (blood, saliva). Further, experts in biophysics gather information on the structure and function of participants’ brains every two years.
A similar study of young children in the first decade of life beginning with the prenatal period, the HEALthy Brain and Child Development (HBCD) study, supported by HEAL, NIDA, and several other NIH institutes and centers, is now underway at 25 research sites across the country. A range of scientific specialists, similar to that in the ABCD study, is involved in this effort. In this case, they are aided by experts in obstetric care and in infant neuroimaging.
For both of these studies, teams of data scientists validate and curate all the information generated and make it available to researchers across the world. This makes it possible to investigate complex questions such as human neurodevelopmental diversity and the effects of genes and social experiences and their relation to mental health. More than half of the publications using ABCD data have been authored by non-ABCD investigators taking advantage of the open-access format.
Yet, institutions that conduct and fund science—including NIH—have been slow to support and reward collaboration. Because authorship and funding are so important in tenure and promotion decisions at universities, for example, an individual’s contribution to larger, multi-investigator projects on which they may not be the grantee or lead author on a study publication may carry less weight.
For this reason, early-career scientists may be particularly reluctant to collaborate on team projects. Among the recommendations of a 2015 National Academies of Sciences, Engineering, and Medicine (NASEM) report, Enhancing the Effectiveness of Team Science, was that universities and other institutions should find effective ways to give credit for team-based work to assist promotion and tenure committees.
The strongest teams will be diverse in other respects, not just scientific expertise. Besides more actively fostering productive collaborations across disciplines, NIH is making a more concerted effort to promote racial equity and inclusivity in our research workforce, both through the NIH UNITE Initiative and through Institute-specific initiatives like NIDA’s Racial Equity Initiative.
To promote diversity, inclusivity, and accessibility in research, the BRAIN Initiative recently added a requirement in most of its funding opportunity announcements (FOAs) that has applicants include a Plan for Enhancing Diverse Perspectives (PEDP) in the proposed research. The PEDPs are evaluated and scored during the peer review as part of the holistic considerations used to inform funding decisions. These long-overdue measures will not only ensure that NIH-funded science is more diverse, but they are also important steps toward studying and addressing social determinants of health and the health disparities that exist for so many conditions.
Increasingly, scientific discovery is as much about exploring new connections between different kinds of researchers as it is about finding new relationships among different kinds of scientific databases. The challenges before us are great—ending the COVID pandemic, finding a solution to the addiction and overdose crisis, and so many others—and increased collaboration between scientists will give us the greatest chance to successfully overcome these challenges.

Research to Address the Real-Life Challenges of Opioid Crisis
Posted on by Lawrence Tabak, D.D.S., Ph.D.
While great progress has been made in controlling the COVID-19 pandemic, America’s opioid crisis continues to evolve in unexpected ways. The opioid crisis, which worsened during the pandemic and now involves the scourge of fentanyl, claims more than 70,000 lives each year in the United States [1]. But throughout the pandemic, NIH has continued its research efforts to help people with a substance use disorder find the help that they so need. These efforts include helping to find relief for the millions of Americans who live with severe and chronic pain.
Recently, I traveled to Atlanta for the Rx and Illicit Drug Summit 2022. While there, I moderated an evening fireside chat with two of NIH’s leaders in combating the opioid crisis: Nora Volkow, director of the National Institute on Drug Abuse (NIDA); and Rebecca Baker, director of Helping to End Addiction Long-term® (HEAL) initiative. What follows is an edited, condensed transcript of our conversation.
Tabak: Let’s start with Nora. When did the opioid crisis begin, and how has it changed over the years
Volkow: It started just before the year 2000 with the over-prescription of opioid medications. People were becoming addicted to them, many from diverted product. By 2010, CDC developed guidelines that decreased the over-prescription. But then, we saw a surge in heroin use. That turned the opioid crisis into two problems: prescription opioids and heroin.
In 2016, we encountered the worst scourge yet. It is fentanyl, an opioid that’s 50 times more potent than heroin. Fentanyl is easily manufactured, and it’s easier than other opioids to hide and transport across the border. That makes this drug very profitable.
What we have seen during the pandemic is the expansion of fentanyl use in the United States. Initially, fentanyl made its way to the Northeast; now it’s everywhere. Initially, it was used to contaminate heroin; now it’s used to contaminate cocaine, methamphetamine, and, most recently, illicit prescription drugs, such as benzodiazepines and stimulants. With fentanyl contaminating all these drugs, we’re also seeing a steep rise in mortality from cocaine and methamphetamine use in African Americans, American Indians, and Alaska natives.
Tabak: What about teens? A recent study in the journal JAMA reported for the first time in a decade that overdose deaths among U.S. teens rose dramatically in 2020 and kept rising through 2021 [2]. Is fentanyl behind this alarming increase?
Volkow: Yes, and it has us very concerned. The increase also surprised us. Over the past decade, we have seen a consistent decrease in adolescent drug use. In fact, there are some drugs that have the lowest usage rates that we’ve ever recorded. To observe this more than doubling of overdose deaths from fentanyl before the COVID pandemic was a major surprise.
Adolescents don’t typically use heroin, nor do they seek out fentanyl. Our fear is adolescents are misusing illicit prescriptions contaminated with fentanyl. Because an estimated 30-40 percent of those tainted pills contain levels of fentanyl that can kill you, it becomes a game of Russian roulette. This dangerous game is being played by adolescents who may just be experimenting with illicit pills.
Tabak: For people with substance use disorders, there are new ways to get help. In fact, one of the very few positive outcomes of the pandemic is the emergence of telehealth. If we can learn to navigate the various regulatory issues, do you see a place for telehealth going forward?
Volkow: When you have a crisis like this one, there’s a real need to accelerate interventions and innovation like telehealth. It certainly existed before the pandemic, and we knew that telehealth was beneficial for the treatment of substance use disorders. But it was very difficult to get reimbursement, making access extremely limited.
When COVID overwhelmed emergency departments, people with substance use disorders could no longer get help there. Other interventions were needed, and telehealth helped fill the void. It also had the advantage of reaching rural populations in states such as Kentucky, West Virginia, Ohio, where easy access to treatment or unique interventions can be challenging. In many prisons and jails, administrators worried about bringing web-based technologies into their facilities. So, in partnership with the Justice Department, we have created networks that now will enable the entry of telehealth into jails and prisons.
Tabak: Rebecca, it’s been four years since the HEAL initiative was announced at this very summit in 2018. How is the initiative addressing this ever-evolving crisis?
Baker: We’ve launched over 600 research projects across the country at institutions, hospitals, and research centers in a broad range of scientific areas. We’re working to come up with new treatment options for pain and addiction. There’s exciting research underway to address the craving and sleep disruption caused by opioid withdrawal. This research has led to over 20 investigational new drug applications to the FDA. Some are for repurposed drugs, compounds that have already been shown to be safe and effective for treating other health conditions that may also have value for treating addiction. Some are completely novel. We have also initiated the first testing of an opioid vaccine, for oxycodone, to prevent relapse and overdose in high-risk individuals.
Tabak: What about clinical research?
Baker: We’re testing multiple different treatments for both pain and addiction. Not everyone with pain is the same, and not every treatment is going to work the same for everyone. We’re conducting clinical trials in real-world settings to find out what works best for patients. We’re also working to implement lifesaving, evidence-based interventions into places where people seek help, including faith, community, and criminal justice settings.
Tabak: The pandemic highlighted inequities in our health-care system. These inequities afflict individuals and populations who are struggling with addiction and overdose. Nora, what needs to be done to address the social determinants of racial disparities?
Volkow: This is an extraordinarily important question. As you noted, certain racial and ethnic groups had disproportionately higher mortality rates from COVID. We have seen the same with overdose deaths. For example, we know that the most important intervention for preventing overdoses is to initiate medications such as methadone, buprenorphine or vivitrol. But Black Americans are initiated on these medications at least five years later than white Americans. Similarly, Black Americans also are less likely to receive the overdose-reversal medication naloxone.
That’s not right. We must ask what are the core causes of limited access to high-quality health care? Low income is a major contributing factor. Helping people get an education is one of the most important factors to address it. Another factor is distrust of the medical system. When racial and ethnic discrimination is compounded by discrimination because a person has a substance use disorder, you can see why it becomes very difficult for some to seek help. As a society, we certainly need to address racial discrimination. But we also need to address discrimination against substance use disorders in people of all races who are vulnerable.
Baker: Our research is tackling these barriers head on with a direct focus on stigma. As Nora alluded to, oftentimes providers may not offer lifesaving medication to some patients, and we’ve developed and are testing research training to help providers recognize and address their own biases and behaviors in caring for different populations.
We have supported research on the drivers of equity. A big part of this is engaging with people with lived experience and making sure that the interventions being designed are feasible in the real world. Not everyone has access to health insurance, transportation, childcare—the support that they may need to sustain treatment and recovery. In short, our research is seeking ways to enhance linkage to treatment.
Nora mentioned the importance of telehealth in improving equity. That’s another research focus, as well as developing tailored, culturally appropriate interventions for addressing pain and addiction. When you have this trust issue, you can’t always go in with a prescription or a recommendation from a physician. So in American and Alaskan native communities, we’re integrating evidence-based prevention approaches with traditional practices like wellness gatherings, cooking together, use of sage and spirituality, along with community support, and seeing if that encourages and increases the uptake of these prevention approaches in communities that need it so much.
Tabak: The most heartbreaking impact of the opioid crisis has been the infants born dependent on opioids. Rebecca, what’s being done to help the very youngest victims of the opioid crisis born with neonatal opioid withdrawal syndrome, or NOWS?
Baker: Thanks for asking about the infants. Babies with NOWS undergo withdrawal at birth and cry inconsolably, often with extreme stomach upset and sometimes even with seizures. Our research found that hospitals across the country vary greatly in how they treat these babies. Our program, ACT NOW, or Advancing Clinical Trials in Neonatal Opioid Withdrawal, aims to provide concrete guidance for nurses in the NICU treating these infants. One of the studies that we call Eat, Sleep, Console focuses on the abilities of the baby. Our researchers are testing if the ability to eat, sleep, or be consoled increases bonding with the mother and if it reduces time in the hospital, as well as other long-term health outcomes.
In addition to that NOWS program, we’ve also launched the HEALthy Brain and Child Development Study, or HBCD, that seeks to understand the long-term consequences of opioid exposure together with all the other environmental and other factors the baby experiences as they grow up. The hope is that together these studies will inform future prevention and treatment efforts for both mental health and also substance use and addiction.
Tabak: As the surge in heroin use and appearance of fentanyl has taught us, the opioid crisis has ever-changing dynamics. It tells us that we need better prevention strategies. Rebecca, could you share what HEAL is doing about prevention?
Baker: Prevention has always been a core component of the HEAL Initiative in a number of ways. The first is by preventing unnecessary opioid exposures through enhanced and evidence-based pain management. HEAL is supporting research on new small molecules, new devices, new biologic therapeutics that could treat pain and distinct pain conditions without opioids. And we’re also researching and providing guidance for clinicians on strategies for managing pain without medication, including acupuncture and physical therapy. They can often be just as effective and more sustainable.
HEAL is also working to address risky opioid use outside of pain management, especially in high-risk groups. That includes teens and young adults who may be experimenting, people lacking stable housing, patients who are on high-dose opioids for pain management, or they maybe have gone off high-dose opioids but still have them in their possession.
Finally, to prevent overdose we have to give naloxone to the people who need it. The HEALing Communities Study has taken some really innovative approaches to providing naloxone in libraries, on the beach, and places where overdoses are actually happening, not just in medical settings. And I think that will be, in our fight against the overdose crisis, a key tool.
Volkow: Larry, I’d like to add a few words on prevention. There are evidence-based interventions that have been shown to be quite effective for preventing substance use among teenagers and young adults. And yet, they are not implemented. We have evidence-based interventions that work for prevention. We have evidence-based interventions that work for treatment. But we don’t provide the resources for their implementation, nor do we train the personnel that can carry it over.
Science can give us tools, but if we do not partner at the next level for their implementation, those tools do not have the impact they should have. That’s why I always bring up the importance of policy in the implementation phase.
Tabak: Rebecca, the opioid crisis got started with a lack of good options for treating pain. Could you share with us how HEAL’s research efforts are addressing the needs of millions of Americans who experience both chronic pain and opioid use disorder?
Baker: It’s so important to remember people with pain. We can’t let our efforts to combat the opioid crisis make us lose sight of the needs of the millions of Americans with pain. One hundred million Americans experience pain; half of them have severe pain, daily pain, and 20 million have such severe pain that they can’t do things that are important to them in their life, family, job, other activities that bring their life meaning.
HEAL recognizes that these individuals need better options. New non-addictive pain treatments. But as you say, there is a special need for people with a substance use disorder who also have pain. They desperately need new and better options. And so we recently, through the HEAL Initiative, launched a new trials network that couples medication-based treatment for opioid use disorders, so that’s methadone or buprenorphine, with new pain-management strategies such as psychotherapy or yoga in the opioid use disorder treatment setting so that you’re not sending them around to lots of different places. And our hope is that this integrated approach will address some of the fragmented healthcare challenges that often results in poor care for these patients.
My last point would be that some patients need opioids to function. We can’t forget as we make sure that we are limiting risky opioid use that we don’t take away necessary opioids for these patients, and so our future research will incorporate ways of making sure that they receive needed treatment while also preventing them from the risks of opioid use disorder.
Tabak: Rebecca, let me ask you one more question. What do you want the folks here to remember about HEAL?
Baker: HEAL stands for Helping to End Addiction Long-term, and nobody knows more than the people in this room how challenging and important that really is. We’ve heard a little bit about the great promise of our research and some of the advances that are coming through our research pipeline, new treatments, new guidance for clinicians and caregivers. I want everyone to know that we want to work with you. By working together, I’m confident that we will tailor these new advances to meet the individual needs of the patients and populations that we serve.
Tabak: Nora, what would you like to add?
Volkow: This afternoon, I met with two parents who told me the story of how they lost their daughter to an overdose. They showed me pictures of this fantastic girl, along with her drawings. Whenever we think about overdose deaths in America, the sheer number—75,000—can make us indifferent. But when you can focus on one person and feel the love surrounding that life, you remember the value of this work.
Like in COVID, substance use disorders are a painful problem that we’re all experiencing in some way. They may have upset our lives. But they may have brought us together and, in many instances, brought out the best that humans can do. The best, to me, is caring for one another and taking the responsibility of helping those that are most vulnerable. I believe that science has a purpose. And here we have a purpose: to use science to bring solutions that can prevent and treat those suffering from substance use disorders.
Tabak: Thanks to both of you for this enlightening conversation.

Addressing the Twin Challenges of Substance Use Disorders and COVID-19
Posted on by Dr. Francis Collins
The coronavirus disease 2019 (COVID-19) pandemic is having a wide range of negative impacts on people affected by a variety of health conditions. Among the hardest hit are individuals struggling with substance use disorders, with recent data indicating that suspected drug-related overdoses and deaths are on the rise across the United States [1].
One recent analysis of nationwide surveillance data, collected by the federal Overdose Detection Mapping and Application Program, found that suspected drug overdoses rose by 18 percent in March, 29 percent in April, and 42 percent in May compared to the same months in 2019 [2]. Another analysis of state and local mortality data showed that drug-related deaths have increased about 13 percent so far this year, compared to last year [3].
To find out what may be contributing to this tragic situation and learn what NIH-funded research is doing to help, I recently had a conversation with Dr. Nora Volkow, Director of NIH’s National Institute on Drug Abuse (NIDA). Here’s a condensed version of our interview, which took place via videoconference, with both of us linking in from our homes near NIH’s main campus in Bethesda, MD
Collins: Here we are today talking about two public health crises: the crisis of COVID-19 and another crisis that has been going on for quite some time, of drug overdoses and drug deaths. The opioid crisis is difficult in any circumstance, but when you add to it what’s happening right now with the global COVID-19 pandemic, it becomes difficult squared. What has happened during this pandemic?
Volkow: One of the first things that we’ve heard from the communities and the families afflicted by addiction is that the support systems that were there to help people achieve recovery are no longer present. At the same time, it’s been much harder to get access to some of the treatment programs, including hospital emergency departments that can initiate treatment. It’s also been more difficult to access syringe exchange programs and programs, like Narcotics Anonymous, that provide people with a mentor and a social support system that’s fundamental for recovery. Part of recovery is also for individuals to work at re-building their lives, and that too has become much more challenging due to the threat of COVID-19.
All of these aspects are translating into much more stress. And stress, as we know, is one of the factors that leads people to relapse. Stress is also a factor that leads many to increase the consumption of drugs.
Collins: What about the impact of the stay-at-home orders for people who are depending on social networks? You’ve talked about Narcotics Anonymous as an example. But for anybody who’s faced stress challenges, mental health issues, which often coexist with drug problems, what’s the effect of losing those face-to-face social connections?
Volkow: Isolation is difficult for anyone. We depend on others for our wellbeing. The harder our situation, the more vulnerable we are if we don’t have those support systems.
One of the major concerns that we’ve had all along is not just the enormous risk of relapse in many people, but also the risk of suicide—which is always much higher in individuals that are addicted to drugs, particularly to opioids. Indeed, there’s been an increase in the number of suicides associated with the COVID-19 pandemic, including among people that are addicted.
One of the elements we are using to try to overcome that is virtual interactions, like we are having right now. They are fulfilling, certainly for me. And when we’ve surveyed patients and families to see how much these virtual support systems are helping them, we see in many instances that this can be lifesaving. For example, with telehealth, a physician now can prescribe buprenorphine [a treatment medication] without necessarily having to see the individual physically. That’s a major breakthrough because it expands the number of people that can be treated. So, you can provide buprenorphine, and you can also provide support that someone with co-morbid mental illness may need. It’s not the same as physically being with others, but we have to recognize virtual technologies may enable greater equity in providing treatments.
Collins: What’s happened to methadone clinics, a place where people were required to show up in person every day? What’s become of people who depended on those?
Volkow: These spaces are small and there’s not enough staff, so it was very, very high risk. So, one of the positives of COVID-19 is that there was a change in the policy that enabled a methadone clinic to provide take-home methadone for patients, rather than have them come in daily and often at very restricted times, which made it incredibly difficult to comply.
We’re now trying to evaluate the outcomes when people are given take-home methadone. If we can show from evidence that the outcomes are as good as when you go in daily, then we hope that will help to transform these policies permanently.
Collins: So, there’s a silver lining in a few places. Are people who suffer from drug use disorders at increased risk of getting sick from COVID-19?
Volkow: There are many factors that place them at very, very high risk: pharmacological, structural, and social.
Pharmacological, because these drugs negatively affect multiple systems in your body and one of the main targets is the pulmonary system. If your pulmonary system already has pathology because of prior conditions, it’s much easier for the virus to actually infect you and lead to negative outcomes. That pertains to cigarette smoking that produces COPD and pulmonary damage, as well as to very toxic drugs like methamphetamine, which produces pulmonary hypertension; or opioids, which actually depress respiration and produce hypoxia.
You can see that the combination of depressed respiration and having a viral infection that attacks your lungs is not going to be positive. Indeed, it is very likely that that combination lowers the threshold for people to die from overdoses or to die from COVID-19. Drugs can also affect the cardiovascular system and the metabolic system, so all of the factors that we’ve identified as conditions that make you more vulnerable to COVID-19 are affected by drugs.
Then there are structural issues. We’ve already discussed methadone clinics, which put people together in very close spaces. Before COVID-19, one of our main priorities was to bring the treatment of substance use disorder and the screening into the healthcare system. But now the healthcare system is saturated and individuals who’ve gotten their treatment in healthcare systems no longer can access them and that restricts their ability to seek help. In our country, we basically criminalize people who take drugs, and many of them are in jail systems and prisons, where COVID-19 infections can rapidly occur. That is another element where they are at much higher risk.
Also, the number of individuals with substance use disorder who have medical insurance is much less than that of the general population. Not having such insurance is associated with a greater likelihood of having chronic medical conditions, which again is another risk factor for COVID-19. This mixes the structural with the social and, in the social category, you also have stigma.
Stigmatizing individuals with addiction makes them very vulnerable. That’s because, first of all, they are afraid to seek help—they don’t want to be discriminated against. Secondly, if they are in a situation where decisions are being made about providing medical care when resources are limited, that stigma can make them much more vulnerable.
While we are dealing with COVID-19, we cannot ignore the disparities that exist in our society. This pandemic has made it very clear how horrifically disparate health outcomes are between groups of people in our country.
Collins: Nora, you’ve been a real leader on what we might do to try to bring attention to helping people with drug use problems in the criminal justice system. This is often a point where an opportunity for treatment arises, but unfortunately that opportunity is often missed.
Volkow: One of our priorities as we address the opioid crisis is to do research in justice settings in order to be able to identify the models that lead to the best outcomes and to understand how to implement them. This has resulted in the creation of a research network that enables us to connect across the justice and the healthcare systems.
The network that started to emerge before COVID-19 hit has given us an opportunity to get direct information about what’s happening out there. From what we know, because prisons and jails are at such high risk for infection, many states—if not all—are releasing people that are not violent into their communities. Many of them have a substance use disorder. If someone has a long history of a substance use disorder, you cannot release them into the community without a support system, especially in the midst of the COVID-19 pandemic, where it’s hard to find a job and their families may be rejecting them. You can predict the outcome is going to be very poor, including dying from overdoses.
So, we now have a chance to show that treating these people in their community with appropriate support is going to lead to much better outcomes than leaving them in jail or prison. We are now working with our researchers and with appropriate agencies to figure out how to provide the support that’s necessary as individuals with substance use disorders are released into their communities. It can go both ways. Without support, the outcomes may be very poor. With support, we have the opportunity of transforming the way that we deal with addiction in this country.
Collins: A lot of people may not realize that effective medical treatment for substance use disorders does exist. Treatment has been demonstrated to change lives and improve outcomes over the long term. Still, a lot of folks out there think it’s just hopeless, or, alternatively, if someone just had a little bit more willpower, he or she would be able to take care of this. Please say a little bit about what the current treatment options are, and what the evidence is that they’re needed if you’re going to help somebody recover from a substance use disorder.
Volkow: There are medications for alcoholism and medications for nicotine use disorders. But, by far, the most effective medications are for opioid addiction. It’s very frustrating these medications are not necessarily given to patients—or sometimes even given to patients, but they reject them. I think part of the issue is because of the stigma against the medications. The opioid crisis has helped smooth that out somewhat, so there’s been a greater acceptance of medication. In partnership with the pharmaceutical industry, we have also been working towards developing extended-release formulations that make it much easier for people to take these medications.
In parallel, not just for opioid addiction, we have built up the scientific evidence for behavioral interventions that can improve outcomes for people with substance use disorder in general, if provided concurrently with medical treatment. Recognizing that there is a high risk of comorbidity with mental illness, we also need to provide treatments to address psychiatric disease problems or symptoms, as well as the addiction process. A lot of the work right now is going into creating models that allow this comprehensive treatment, tailored to the needs of the person.
Collins: Where can people who have a family member or friend who’s struggling with substance use disorder in the midst of COVID-19 go to get reliable evidence-based information about treatment programs?
Volkow: They can go to the NIDA website or the website of NIH’s sister agency, the Substance Abuse and Mental Health Services Administration (SAMHSA). One of the problems is that there hasn’t been any way of assessing the quality of treatment for substance use disorder. For many other conditions, you can check the track records of this or that hospital for this or that surgery, but such information does not exist for substance use disorder.
So, we’ve been funding researchers to develop metrics that can predict good outcomes in treatment programs. These metrics can be based on the experiences of people and family that actually took these services, and from the structural characteristics of the program, such as whether they have the evidence-based components shown by research to lead to better outcomes. Researchers are now developing “report cards” for treatment programs that hopefully will do two things: give a family member a sense of how others are rating a program, and, importantly, incentivize treatment programs to do better.
Collins: It would be wonderful to have more objective data for people searching for good answers. Now, let’s talk about HEAL, which stands for Helping to End Addiction Long-term. HEAL is a trans-agency initiative funded by the Congress to support research to address, from multiple different directions, multiple different problems relating to addiction and chronic pain.
How does the HEAL initiative need to adapt to the current health crisis of COVID-19? And what’s your institute doing to try to address some of the significant problems that have emerged in just the last two or three months?
Volkow: COVID-19 has placed HEAL and much of our other research on a very slow trajectory. For example, one program that we were very interested in expanding was the use of the emergency department for the screening of opioid use disorder and the initiation of treatment medications. Another major HEAL program was going to start using the justice system to conduct clinical trials to evaluate the outcomes of different types of medication for opioid use disorder. They are all basically on hold.
Collins: Nora, what’s your hope going forward over the next few months? What can NIH do to try to address this situation in the most effective way possible?
Volkow: I am optimistic because I can see how science can help to solve extremely challenging problems. I think this is the time for science to shine again and show us that methodologies aimed at gathering objective data to develop optimal solutions can resolve problems. But the question is: how long will it take?
I’ve been very impressed about how these devastating circumstances have led us to question the pace at which we moved projects in the past. I think it is wonderful that we have recognized that time is a luxury, that we need to move rapidly. With respect to the issue of substance use disorders, I would hope that, as we as a nation become aware of the suffering that the COVID-19 pandemic is putting on all of us, we become more empathetic to the suffering of others.
And as I see the movements across the country speaking out against injustice, I would hope that this will also extend to diseases that have been stigmatized. We need to modify our stigma so we provide the same level of importance to treating these diseases and supporting people afflicted by them.
I think that science will prevail. What is going to be important is that we also allow for our humanity in order to use that science in a way that everyone can take advantage of it.
Collins: That’s a wonderful way to wind up because I think the calling to bring together science and compassion is what drives all of us who have the privilege of working at NIH, the largest supporter of biomedical research in the world. Our purpose is clear: to find answers for all of these difficult problems that cause suffering and early death for people who deserve better.
Our vision is set on helping the most vulnerable populations right now. COVID-19 has pointed us toward that, and our discussion about those who suffer from substance use disorders also focuses on that.
I’m always one who likes to talk about hope, because, after all, that’s what we get up in the morning thinking about at NIH. We hope that our research efforts are going to lead to a new vaccine or a new treatment for COVID-19, or a better way of helping people who have been afflicted with drug problems.
Yet one of my favorite sayings is that “hope is a privilege that attaches to action.” This means that you can’t just say “Well, I hope for something,” unless you attach that hope to concrete actions you’re going to take.
Nora, your institute has been living that out. You don’t just hope that something good will happen to turn the tide of this terrible crisis of suffering and death from opioid overdoses, you’re all about action. So, thank you for your incredible dedication to the science and to the people whom we are trying to serve.
Volkow: Francis, thanks very much for your support.

First-term finals are nearly upon us and sadly a disturbing percentage of high school seniors are abusing stimulants Adderall (dextroamphetamine) and Ritalin (methylphenidate), which are prescribed for Attention Deficit Hyperactivity Disorder (ADHD). These drugs increase alertness, attention, and energy the same way cocaine does—by boosting the amount of the neurotransmitter dopamine.
Even though these drugs are legal, they’re quite dangerous if not used properly. Taking high doses can cause irregular heartbeat, heart failure, or seizures. High doses of these stimulants can lead to hostility or feelings of paranoia. So, rather than popping pills, it’s a lot safer—and smarter—to boost your grades the old-school way: by studying.
