For the first time in years, the United States is recording genuine progress in the war against fentanyl. Provisional CDC data released in May 2026 shows approximately 69,973 drug overdose deaths for the 12 months ending December 2025 — a 13.9% decline compared to the prior year, and a dramatic improvement from the 2022 peak of 108,000 deaths. Expanded naloxone access, faster treatment initiation, harm-reduction programs, and — according to some researchers — reduced drug supply from policy changes affecting precursor chemical manufacturing have all contributed to this national trend.
Arizona is a stark exception. According to a February 2026 analysis by a Maricopa County prosecutor writing in the Arizona Capitol Times, for the 12-month period ending September 2025, Arizona was one of only five states to record an increase in overdose deaths. It had the largest increase of any state. While the country saw a 21% decline in overdose deaths over that period, Arizona recorded a 17% increase. That is not a rounding error or a data artifact. That is a public health crisis moving in the opposite direction from the national trend, in one of the four largest metropolitan areas in the United States.
Maricopa County's Grim Numbers
The epicenter of Arizona's overdose crisis is Maricopa County — home to Phoenix and its suburbs, with a population of approximately 4.7 million people. According to the Maricopa County Fatal Overdose Data Dashboard, fentanyl was involved in 59% of fatal overdoses in 2024, while methamphetamine was involved in 67%. Polysubstance combinations — particularly fentanyl and methamphetamine together — represent the most lethal trend in the county's drug mortality data.
The role of methamphetamine in Arizona's overdose crisis is particularly significant and often overlooked in national reporting. Methamphetamine raises core body temperature and impairs the body's ability to regulate heat — a combination that is uniquely deadly in a desert climate where summer temperatures routinely exceed 110°F. Maricopa County data documents a direct link between methamphetamine use and heat deaths, with the county noting that "methamphetamines are involved in most drug-related heat deaths in Maricopa County." In Phoenix, the convergences of extreme heat, homelessness, and polysubstance addiction create a deadly triplicate threat that other cities simply do not face at the same scale.
The Xylazine Dimension
Compounding the fentanyl crisis is the rising presence of xylazine — a veterinary tranquilizer used to sedate large animals — being added to illicit fentanyl supplies by drug traffickers seeking to prolong the drug's effects and reduce costs. Known on the street as "tranq" or the "zombie drug," xylazine creates distinctive, horrifying necrotic skin wounds at injection sites that do not respond to standard wound care. More critically for emergency responders, xylazine is not an opioid — meaning naloxone (Narcan), the standard overdose reversal agent, does not reverse its sedative effects. A person overdosing on fentanyl-xylazine combination drugs may appear to respond partially to naloxone but remain dangerously sedated.
The DEA Phoenix Field Division launched a mobile drug testing lab in 2024, citing xylazine detection as a major priority. Emergency rooms in Maricopa and Pima counties have reported increasing numbers of patients with unexplained sedation and necrotic wounds — the clinical hallmarks of xylazine exposure. The Arizona Poison and Drug Information Center has issued alerts to health professionals and law enforcement about xylazine-laced fentanyl. The Arizona Attorney General's office has joined a bipartisan coalition of 39 attorneys general seeking federal action to address illicit xylazine, framing it as a public safety emergency.
The Sentencing and Enforcement Debate
The divergence between Arizona's worsening outcomes and the national improvement trend has reignited a debate about the relative roles of enforcement and harm reduction in addressing the overdose crisis. The Maricopa County prosecutor who authored the Arizona Capitol Times analysis called explicitly for "stronger sentencing for traffickers," arguing that the national gains reflect tighter border enforcement and supply disruption that Arizona has not benefited from to the same degree, citing its unique position as a major fentanyl trafficking corridor from Mexico.
Public health advocates push back on this framing, noting that Arizona has simultaneously reduced funding for harm reduction programs and treatment capacity — and that the states making the most progress nationally have generally been those that expanded, rather than restricted, evidence-based interventions, including naloxone distribution, medication-assisted treatment, and syringe service programs. As part of opioid settlement agreements, Arizona is receiving tens of thousands of units of naloxone from Hikma and Amneal Pharmaceuticals in 2026. Whether those resources reach the communities where they are needed most — the homeless encampments and low-income neighborhoods where polysubstance addiction is most prevalent — remains to be seen.
What Phoenix Residents Need to Know
For Phoenix residents, the practical message is this: fentanyl is in virtually every category of illicit drug supply, often without the user's knowledge. Counterfeit pills that look like oxycodone, Xanax, or Adderall are frequently entirely fentanyl. The Maricopa County Substance Use resources page offers information on naloxone distribution, fentanyl test strips, and treatment resources. Fentanyl test strips — which can detect fentanyl in a drug sample before it is consumed — are available and legal in Arizona. Carrying naloxone and knowing how to use it is now, in the words of public health officials, a basic life skill in Maricopa County.
