The Intertwined Crises: Addressing Polysubstance Use and Fentanyl in New England

Posted on September 2, 2025 by Facility Staff

For years, fentanyl has cast a long, dark shadow over New England, devastating communities and claiming countless lives. Its extreme potency has fundamentally reshaped the landscape of addiction. Yet, the crisis has evolved, becoming even more complex and insidious. We’re now facing not just a fentanyl crisis, but an intertwined challenge: polysubstance use, where fentanyl is dangerously mixed with other powerful drugs.

At Serenity at Summit New England, located in Haverhill, MA, we are on the front lines, witnessing these shifts firsthand. We believe that understanding these emerging dangers is crucial for our community, for families, and for anyone seeking or providing help. This isn’t just a clinical update; it’s a vital conversation about protecting lives and adapting our strategies to face the next wave of challenges.

The Evolving Overdose Crisis in Massachusetts

Massachusetts has been profoundly impacted by the opioid epidemic, and while there have been some shifts in the data, the severity of the crisis remains undeniable. The numbers paint a stark picture of the challenges we face.

In 2023, over 2,300 lives were tragically lost to overdose in Massachusetts. What’s particularly alarming is the pervasive presence of fentanyl in these fatalities, with approximately 90% of all overdose deaths involving this potent synthetic opioid. This indicates that fentanyl continues to be the primary driver of overdose mortality in our state, underscoring its relentless grip on communities.

Beyond fentanyl’s singular impact, we are witnessing a concerning rise of “polysubstance” overdoses. This refers to overdoses involving multiple substances, often unknowingly consumed together. It’s increasingly common to find fentanyl mixed with other dangerous drugs like xylazine (“tranq”), benzodiazepines (such as Xanax or Klonopin), and alcohol. This dangerous cocktail creates a highly unpredictable and lethal scenario, making overdose prevention and response more complex than ever before. The combination of these substances significantly increases the risk of respiratory depression and complicates life-saving interventions.

What Is Polysubstance Use?

Polysubstance use refers to the consumption of more than one drug, either at the same time or sequentially. It’s a critical factor in the escalating overdose crisis, particularly in New England.

This mixing of drugs can be either intentional or unintentional. Intentional polysubstance use might occur when individuals combine drugs to enhance effects, mitigate side effects of one drug, or manage withdrawal symptoms. 

However, a growing and far more dangerous trend is the unintentional mixing of drugs. This often happens when illicit substances are adulterated or “laced” with other powerful compounds, such as fentanyl or xylazine, without the user’s knowledge. For example, a user might believe they are taking cocaine or a prescription pill, only to unknowingly consume a lethal dose of fentanyl.

Polysubstance use is often tied to deeper underlying issues. It can be a coping mechanism for individuals struggling with chronic pain management, where they combine substances to find relief. More frequently, it’s a way of self-medicating untreated mental health symptoms like severe anxiety, depression, or the lingering effects of trauma.

When mental health conditions go unaddressed, individuals may turn to multiple substances in a desperate attempt to numb emotional pain or regulate overwhelming feelings, creating a dangerous cycle that requires integrated treatment.

Why This Combination Is So Deadly

The combination of fentanyl with other substances creates a particularly lethal scenario, making overdose prevention and intervention incredibly challenging for first responders and clinicians.

One of the most critical dangers is that overdose reversal drugs may not be fully effective. Naloxone (Narcan), a life-saving medication, is designed to reverse opioid overdoses. However, when non-opioid substances like xylazine are present in the drug supply, naloxone may not be able to reverse the effects of the non-opioid component. While naloxone should always be administered in a suspected opioid overdose, the presence of these adulterants means individuals may still experience severe respiratory depression or other life-threatening effects, requiring immediate medical attention beyond naloxone administration.

The mixing of substances also leads to significantly increased respiratory depression and overdose risk. Fentanyl itself is a powerful respiratory depressant. When combined with other central nervous system depressants like benzodiazepines or alcohol, the risk of slowed or stopped breathing becomes exponentially higher. This synergistic effect can quickly lead to fatal overdose.

Furthermore, the difficulty in knowing what you’re taking is a pervasive and deadly problem. The illicit drug market is flooded with pressed pills mimicking legitimate prescription medications (like Percocet, Xanax, or Adderall) that often contain lethal doses of fentanyl or other synthetic drugs. Users are unaware they are consuming a potentially fatal cocktail. This deception, coupled with the unpredictable nature of adulterants, means every dose carries an unknown and often extreme risk.

The Need for Integrated Treatment

Given the complex and dangerous nature of polysubstance use and fentanyl’s pervasive presence, a truly integrated treatment approach is no longer optional—it’s essential for effective and lasting recovery.

Integrated treatment means addressing all aspects of an individual’s health simultaneously, rather than in silos. This includes:

  • Dual Diagnosis Care for Trauma, Depression, and Anxiety: Many individuals engaging in polysubstance use are doing so to cope with untreated mental health conditions or unresolved trauma. Integrated care provides simultaneous treatment for these co-occurring disorders, recognizing their interconnectedness. Therapies like EMDR and trauma-focused CBT are crucial for healing the underlying pain that drives substance use.
  • Medical Detox Capable of Managing Multiple Withdrawal Risks: The withdrawal process from multiple substances can be complex and dangerous, involving varied and severe symptoms. A specialized medical detox program is essential to safely manage the withdrawal risks associated with different drug classes (e.g., opioids, benzodiazepines, alcohol) under 24/7 medical supervision. This ensures physical stability before therapeutic work begins.
  • Residential Stabilization with Step-Down Options: For many, particularly those with severe polysubstance dependence or complex co-occurring disorders, residential stabilization offers a crucial period of intensive, structured care away from triggers. This is followed by seamless step-down options like Partial Hospitalization Programs (PHP) and Intensive Outpatient Programs (IOP), allowing individuals to gradually reintegrate into daily life with continued robust support. This continuum ensures comprehensive, ongoing care tailored to evolving needs.
