CHICAGO, Illinois, August 5, 2026 — Chicago and Cook County are seeing fewer people die of opioid overdoses — the numbers have continued improving for three years now. A new report shows a drop in opioid deaths appearing to decrease over time. Cook County reported the nation’s steepest decline in overdose deaths since the 2023 national peak of the crisis, according to Cook County Public Health stats.
The numbers themselves tell the story. There were 1,961 opioid-involved overdose deaths in Cook County in 2022. In 2023, that fell to 1,783. In 2024, that number fell even further to 1,138 total, with 835 murders in Chicago and 279 murders in suburban Cook County. Between 2023 and 2024, Chicago’s overdose mortality rate dropped by an incredible 37.2%, compared with a mere drop of 3.9% in the year before.
More recent city data indicate the decline has not slowed. That 683 deaths in Cook County are a 40% decline from last year and the lowest since mid-2013, Cook County’s medical examiner said — when only 500 victims died in Chicago. The total should rise slightly due to pending toxicology results in 180 more cases.
Fentanyl continues to be the main cause of many fatalities. It was connected to 80 percent of all Cook County responses in 2025, and more than 91.7 percent of Chicago deaths that same year. The increase in naloxone distribution — the antidote to opioid overdoses — as well as a general shift toward harm-reduction strategies, is credited by public health officials with much of the turnaround.
In parts of the West Side the improvement is among the sharpest. In Little Village, North Lawndale, Austin and the Garfield Park and Humboldt Park neighborhoods, there were 311 fatal overdoses last year. Despite being the epicenter of Chicago’s opioid crisis, only 96 were found in those same neighborhoods last year — a nearly 70% drop four years ago.
But not everyone is rejoicing without caveats. Although the numbers are fantastic news, Dr. Dan Lustig, president and CEO of Haymarket Center, the suburbs’ most venerable substance abuse and mental health treatment agency, said he believes the progress is built on shaky ground.
Grants, Lustig said, “is the lifeblood and death blood of this field. “Every little slashing of a grant, it hits us big time.” Haymarket Center, which serves approximately 12,000 clients annually.
Racial inequities also linger even with the overall reduction. In 2024, overdose rates for Black people in Chicago were 2.5 times higher than those of whites and nearly four times greater than that among Hispanic individuals, said the joint report. Cook County Department of Public Health Chief Operating Officer Dr. Kiran Joshi essentially addressed the gap directly.
Racial disparities in overdose mortality rates point to the need for greater outreach, especially in Black communities, Joshi bridged up.
Funding could determine whether the decline persists through 2026 and beyond. Sustaining the investment that got Chicago here now is the key challenge for public health officials, who say federal dollars for prevention and treatment programs are on shaky ground.
Public health officials have touted year-to-year declines in overdose deaths as good news but one that does not end the opioid crisis, in a statement released by public health agencies on Aug. 5, 2026. Health agencies typically assess longer term trends alongside emergency medical visits, toxicology data, naloxone availability and distribution, access to treatment and variation by sex or other demographic characteristics to measure the impact of prevention efforts.
Nonetheless, experts say continued funding for treatment and recovery services as well as community outreach will be critical not only to the maintenance gains seen recently, but also in helping to mitigate the disproportionate toll of opioid-related deaths on certain neighborhoods and population groups.
