Arizona has overtaken West Virginia as the state with the highest drug death rate in the contiguous U.S., marking the first time since the prescription opioid epidemic began that West Virginia has lost the distinction. The shift has been fueled in part by Arizona’s transition from counterfeit fentanyl pills to powdered fentanyl, alongside extreme heat, widespread methamphetamine use and homelessness, according to a July 15 report from The New York Times.
Here are six things to know:
- Arizona’s drug death rate overtook West Virginia’s in 2025. It’s the first time since the late-1990s opioid epidemic that’s happened, according to a Times analysis of provisional CDC mortality data. New Mexico also saw a sharp increase, and the two Southwestern states posted the largest jumps in drug death rates in the contiguous U.S. Arizona recorded 43.5 drug deaths per 100,000 people in 2025, nearly double the U.S. rate of 22.1 per 100,000.
- Powdered fentanyl has replaced counterfeit fentanyl pills across much of Arizona. Harm reduction workers, researchers and individuals who use drugs said counterfeit “blues,” made to look like 30-milligram oxycodone tablets but contain fentanyl, have largely disappeared from the illicit market over the past two years. Users instead report widespread availability of powdered fentanyl, which is stronger and more difficult to dose safely because of its inconsistent potency.
- Extreme heat is worsening overdose deaths. A Times analysis of Maricopa County medical examiner data found drug deaths increased by 40% when Phoenix temperatures exceeded 110 degrees. On days reaching 115 degrees, daily drug deaths nearly doubled. Healthcare providers said heat can intensify the effects of both opioids and stimulants.
- Methamphetamine is amplifying the crisis. Researchers estimate 80% to 90% of fentanyl users in the region also use methamphetamine. Clinicians said many people use meth to counter fentanyl’s sedative effects, while the combination of stimulants, opioids and extreme heat significantly increases the risk of fatal overdoses and heat-related illness.
- Homelessness and disruptions to outreach have increased risks. Public health advocates said the dismantling of homeless encampments and new restrictions on providing medical services in city parks have made it more difficult for outreach workers to connect with vulnerable populations and have disrupted established drug supply networks, pushing some users toward unfamiliar sources.
- Early 2026 data offer cautious signs of improvement. Reports of nonfatal overdoses in Phoenix were 17% lower through June than during the same period last year, and preliminary Maricopa County data show drug deaths trending lower. However, officials cautioned that overdose investigations often take months to complete, making it too early to determine whether the decline will continue.
