San Francisco now holds one of the most sobering distinctions in the country when it comes to opioid addiction.

New federal data shows the city has the second-highest fatal overdose rate of any large jurisdiction in the United States, trailing only Baltimore in a crisis that has proven far harder to reverse on the West Coast than in other parts of the country.

The Opioid Crisis by the Numbers in San Francisco

More than 580 people died of a drug overdose in San Francisco from September 2024 to August 2025, according to data from the U.S. Centers for Disease Control and Prevention.

That translates to 70 deaths per 100,000 residents during that 12-month period, more than three times the national average of 20.

Only Baltimore, one of the most deeply affected cities in the country’s overdose crisis, reported a higher rate, with nearly 110 deaths per 100,000 residents during the same period.

More comprehensive data from the San Francisco medical examiner’s office puts the full-year 2025 death toll at 624, down slightly from 635 in 2024 and the lowest total in five years.

CDC data confirmed that even as the overall number of overdose deaths continues to decline, San Francisco’s rate remains far higher than comparable large cities, with other hard-hit counties improving more quickly.

Why San Francisco Has Not Recovered as Fast as Other Cities

The national overdose picture has improved significantly. Researchers have pointed to several factors driving the broader national decline.

This includes greater awareness of the hyper-potent opioid fentanyl, expanded access to the overdose reversal drug naloxone, and a contraction in fentanyl supply as international enforcement efforts have targeted illicit drug networks.

But San Francisco’s numbers have not improved at the same pace as cities like Philadelphia and Nashville, both of which saw sharp declines over the past two years.

Addiction researcher Brendan Saloner of Brown University has suggested that the fentanyl crisis arrived on the East Coast earlier than on the West Coast, and that the trend of declining deaths is therefore moving westward with a delay.

Saloner also warned that if the Trump administration cuts health care funding, access to treatment in cities like San Francisco could shrink significantly, threatening the progress that has been made.

Fentanyl and Emerging Threats in the Drug Supply

Fentanyl remains the primary driver of overdose deaths in San Francisco. According to SF.gov, fentanyl is a synthetic opioid 50 to 100 times stronger than morphine medication and continues to cause high rates of overdose deaths in San Francisco and cities across the nation.

The threat is now evolving further. San Francisco recorded its first fatal overdose involving medetomidine, a potent animal tranquilizer in the same drug family as xylazine, in a case that mirrors complications already seen in Philadelphia and other East Coast cities.

Xylazine, sometimes called “tranq,” is not an opioid and cannot be reversed by naloxone alone. When mixed with fentanyl, it produces prolonged sedation and can cause severe skin ulcerations at injection sites.

Its growing presence in the supply represents a direct challenge to frontline harm reduction workers and first responders.

Understanding Narcotics and Opioid Addiction

Opioids are a class of drugs that include both prescription pain medications such as oxycodone and hydrocodone and illicit substances such as heroin and illicitly manufactured fentanyl.

They work by binding to receptors in the brain that control pain and reward, producing intense feelings of relief that can quickly develop into physical dependence and narcotic addiction.

Opioid overdose occurs when the drug suppresses the respiratory system to the point where breathing slows or stops entirely.

Without immediate intervention, it can be fatal within minutes. The risk increases dramatically when fentanyl or other synthetic opioids are present, because even a small amount can be lethal.

Harm Reduction and Treatment for Opioid Addiction

Naloxone (Narcan): Naloxone is an FDA-approved medication that can rapidly reverse an opioid overdose. It is available without a prescription at most pharmacies in California and through harm reduction organizations across San Francisco.

Anyone who uses opioids, or lives with someone who does, should have naloxone on hand and know how to use it.

Medication-Assisted Treatment: Evidence-based treatment for opioid addiction includes buprenorphine (Suboxone), methadone, and naltrexone.

These medications reduce cravings, prevent withdrawal, and significantly lower the risk of fatal overdose. They are available through opioid treatment programs (OTPs) and office-based providers throughout San Francisco and the broader Bay Area.

Peer Recovery and NA Meetings: Narcotics Anonymous offers ongoing peer support for people in recovery from opioid addiction and other narcotics.

NA meetings provide community, accountability, and a structured 12-step framework that addresses the behavioral and emotional dimensions of addiction alongside medical treatment.
