Illicit Fentanyl-Related Fatalities in Florida: Toxicological Findings

Area of Science:

• Forensic Toxicology
• Public Health
• Opioid Abuse

Background:

• Fentanyl, a potent opioid, shares abuse liability with heroin and prescription opioids.
• A significant increase in fentanyl-related fatalities has been observed nationally.
• The University of Florida Forensic Toxicology Laboratory noted a rise in fentanyl deaths starting mid-2014.

Purpose of the Study:

• To evaluate toxicological findings, demographics, and circumstances of fentanyl-related postmortem cases.
• To analyze cases submitted for toxicological analysis between July 2014 and January 2015.
• To identify trends in fentanyl abuse and fatalities in specific Florida regions.

Main Methods:

• Analysis of 143 postmortem cases tested for fentanyl using gas chromatography-mass spectrometry.
• Determination of fentanyl concentrations with limits of detection (LOD) at 0.62 ng/mL and quantification (LOQ) at 2.5 ng/mL.
• Examination of case origins, decedent demographics, and co-occurring drug findings.

Main Results:

• Quantifiable fentanyl was detected in 50% (n=66) of cases, with concentrations ranging from 2.5 to 68 ng/mL (median: 9.8 ng/mL).
• 85% of cases indicated possible drug abuse, most frequently involving heroin; concurrent use of other opioids and benzodiazepines was common.
• In District 12, 57 out of 59 deaths were attributed to accidental drug intoxication involving fentanyl; decedents were predominantly White males, median age 35, with no fentanyl prescription.

Conclusions:

• The rise in fentanyl-related deaths represents a critical public health concern.
• Findings underscore the urgent need for enhanced prevention and treatment strategies for opioid abuse.
• The study highlights the significant role of fentanyl in recent drug intoxication fatalities in Florida.
