Synthetic opioids like fentanyl accounted for around 3,000 deaths in 2013—by 2018, they accounted for over 30,000.1 Fentanyl is approximately 100 times more potent than morphine, 50 times more potent than heroin. Breathing can stop after use of just two milligrams of fentanyl. That’s about as much as trace amounts of table salt. “Ten years ago,” write the authors of a recent RAND report on the future of fentanyl, “few would have predicted that illicitly manufactured synthetic opioids from overseas would sweep through parts of Appalachia, New England, and the Midwest.” Drug epidemics and outbreaks can be surprising, taking unexpected forms at unpredictable moments in uncharacteristic patterns. But the fentanyl crisis is different. It isn’t just distressingly surprising or one more deadly drug epidemic in a grueling, tragic history of new contagions. Its magnitude, intensity, and sharp variations dwarf previous epidemics with which experts and officials are familiar, and its challenges for public health are novel and, so far, unmanageable. The recent RAND report is a comprehensive overview of the fentanyl crisis’s origins, present status, and, most disturbingly, future.

What is TMS and can it help treat withdrawal, addiction, and patients with SUDs like it can treat depression and OCD?
In April, The Atlantic published a piece about a young woman who became a viral internet sensation after she was photographed wearing a futuristic-looking hat or device on her head.1 Some online commentators dubbed the large, grey headwear, connected by a strap under the chin, “the depression helmet.” What the commentators did not understand is that such devices are part of a safe, effective, FDA-approved treatment for depression: transcranial magnetic stimulation, or TMS. At the University of Florida, in 2008, I was part of a team that purchased one of the first TMS machines sold after FDA approval. We bought other machines and did TMS research as well. Since that time, the technique has been used successfully to treat depression around the world. It was also approved in 2013 for the treatment of pain associated with certain migraine headaches, and more recently approved for the treatment of Obsessive-Compulsive Disease.2
At least 100 randomized clinical trials have been completed in an attempt to find a MAT which might treat cocaine use disorder, employing over 50 chemical compound medications. With very little progress made from early work3, none have been shown to be particularly useful4, until the current day and TMS. Treatment must reverse more than acute or even chronic dopamine neuron effects of cocaine. The TMS research group at the National Institute of Drug Abuse (NIDA) in Baltimore works on TMS research, dopamine plasticity, cocaine and SUD-related dopamine changes. TMS offers us a chance to intervene against cocaine and other substance’s ability to change the firing rates and key brain circuits that ultimately reduce dopamine release. The TMS research group is working to define how SUDs change the brain, intrinsic and synaptic plasticity control dopamine neurons, and what might be done to return the brain to pre-drug functionality.5
NIDA TMS researchers were featured in a cover story on the science of addiction in National Geographic.6 This article describes how a psychiatrist in Italy, who has treated addiction for 30 years, became interested in TMS and began using it for treatment. It also details the successful use of traditional TMS treatment on a chronic relapsing patient, treated as if he had a naturally occurring depression. The psychiatrist, patient, and NIDA researchers are all interviewed for the story. TMS is not shock therapy; it delivers electromagnetic pulses to the brain in dopamine rich areas, resulting in painless, rapid magnetic pulses delivered through a pad or cap or hat. It is called non-invasive, and clearly has the ability to use magnetic stimulation to drive the brain’s circuitry with electric currents. TMS can increase and decrease cortical excitability, through high and low frequency wave generation. Scientists are very excited about this as TMS may help rebuild neural connections, or possibly regenerate dopamine systems damaged by substance use. The psychiatrist featured in the National Geographic article, Luigi Gallimberti, MD, has subsequently used TMS to treat other addictions.
Medication assisted therapies are approved and used for detoxification, maintenance, and relapse prevention. Unfortunately, these do not address many of the changes produced by cocaine and other drugs. Even patients following these treatment plans and taking medications often feel a lack of energy, diminished pleasure, and declining enthusiasm, and drop out of treatment. TMS might not help people to stop using drugs, but it could be beneficial in helping with addiction and post-addiction related depression and anhedonia.7 TMS researchers have become part of a promising frontier for combating craving, addiction, relapse, and co-occurring depression. Greeting with laughter images of TMS devices, caps, and hats is a perfectly unhelpful reaction in the middle of a major opioid crisis.
FDA approval for treating depression through TMS piqued interest in applying the technique to substance use disorders, since depression is often a major part of SUDs, and a cause of relapses and overdoses, as a recent consensus review on the current state of non-invasive brain stimulation science pointed out. Neuroscience research has helped establish connections between substance-using behavior and particular neural circuits, which prompted additional interest in using TMS and related techniques to treat substance use disorders. TMS is no longer an experiment. With time, SUD researchers have compiled more studies on non-invasive brain stimulation, symptoms, and outcomes, leading to new reviews on relative effectiveness and future development prospects.

It is important to understand how substances, including prescribed medications, can interact with each other and other substances. Mixing medications-- whether the medication is prescribed by a doctor, available over-the-counter, or otherwise-- can be dangerous both in the long and the short-term. Make sure to consult with your prescribing doctor when you have any questions about what medications you are taking and how they may interact with other substances you may be using. It is also important to know what your medications are being prescribed to treat, and to be honest when your doctor ask what medications or supplements you are taking so they can better understand what may interact negatively with each other.
It is important to note that mixing 2 or more substances significantly increases the risk of dangerous or fatal effects. For example, a study done in Florida found that over 90% of opioid overdose deaths in the state included other, non-opioid drugs with an average of 2–3 drugs other than the opioids found at autopsy.

The physiological cravings that accompany addiction, along with memory cues and environment triggers specific to each patient can cause a recurrence of use or relapse. As such, effective treatment needs to address a person’s behavioral health and help them learn how to cope with stress and environmental triggers.
