Fatal Overdose Data

MCDPH tracks fatal overdoses using two data sources. The fatal overdose charts below rely on these two data sources, which are indicated in each chart: 

  1. Vital statistics data using death certificates for Maricopa County residents. 
  2. Deaths in Maricopa County which are potentially due to unnatural causes are investigated by the Maricopa County Office of the Medical Examiner (OME) and postmortem examinations and laboratory testing is performed. MCDPH uses OME toxicology data for monitoring drug-related deaths that occurred within Maricopa County.

Please note that that any fatal overdose statistics using 2022 toxicology data from the OME are still provisional. Data are subject to change once finalized.

July is typically the hottest month in Maricopa County. Because stimulants such as cocaine and methamphetamines can induce hyperthermia (i.e., overheating), we have been seeing an increase in fatal overdoses during the month of July.

Suicide Data

Suicide Death Data by Mechanism

Firearms were used in most suicide deaths between 2018-2022. However, the mechanism of suicide death can vary by population demographic. Youth suicides, for example, have a higher proportion of deaths by hanging compared to adults. And although firearms are the most common suicide mechanism for both men and women, poisonings are more common among women.

Nonfatal Overdose Report

In March 2021, MCDPH began case investigations of suspected nonfatal opioid overdoses reported by Maricopa County hospital facilities.  Staff attempt telephone interviews with a sample of case-patients to better interpret the findings and to specifically help inform overdose prevention interventions for people who use drugs.

Among approximately 300 case-patients interviewed during the period from 9/1/21through 8/31/22, more than 55% (179 individuals) self-reported recreational drug use. View report findings.
