Fatal drug overdoses among youth aged 15 to 24 in the United States involving synthetic opioids alone—not mixed with other substances—soared by 168 percent over the five-year period from 2018 to 2022, a new study shows. , the work also found that youth overdose rates and drug combinations varied significantly across age, sex and race/ethnicity.

Led by ������� Grossman School of Medicine, the new study is the first, say investigators, to identify which specific combinations of drugs drove synthetic opioid-involved fatal overdoses among young people across sociodemographic groups over time.

Overdoses that involved synthetic opioids alone—predominantly fentanyl—had the highest rates of fatalities when compared to overdoses involving other drug combinations examined by the researchers. This was regardless of age, sex and race/ethnicity.

“Before we looked at the data, we thought we would find that the majority of fatal youth overdoses involved fentanyl combined with other substances, such as prescription opioids or cocaine,” said , assistant professor in the and senior author of the study. “Instead, we found the opposite—that most deaths were caused by fentanyl alone. Our analysis sheds light on the changing nature and risks of the drug supply and how they impact key demographic groups. Some may think they are taking one substance but are actually exposed to another.”

According to Dr. Krawczyk, who is also associate director of the Center for Opioid Epidemiology and Policy at ������� Langone, their findings underscore the need to tailor overdose prevention strategies that include harm reduction services specifically to youth to prevent death and suffering among this under-studied population.

How the Study Was Conducted

Analyzing data from the National Center for Health Statistics, the researchers characterized trends in overdose death involving synthetic opioids (predominantly fentanyl) alone, as well as in combination with five other drugs that are common (benzodiazepines, heroin, prescription opioids, cocaine, and other stimulants) among youth aged 15 to 24 across age, sex and race/ethnicity over five years, from 2018 to 2022.

The investigators found that during the study period, overdoses involving synthetic opioids alone increased by 168 percent—the highest rates of fatalities compared to those that included a combination of the examined drugs, regardless of age, sex and race/ethnicity.

After deaths due to synthetic opioids/fentanyl alone, the next highest rates of fatal overdoses involved fentanyl combined with cocaine or another stimulant; however, rates differed by age, sex, race/ethnicity and over time. In 2018, White non-Hispanic youth had the highest rates of overdoses involving synthetic opioids/fentanyl alone. By 2022, rates of overdose deaths involving only fentanyl among Black American, American Indian and Alaska Native, and Hispanic youth exceeded White non-Hispanic youth. When it came to the impact of sex and age, fatal overdoses across all groups were highest among males, as well as all youth aged 20 to 24.

According to the research team, understanding the landscape of overdose patterns provides needed context in terms of how to best inform specific public health interventions that can prevent more deaths.

Megan Miller, a research coordinator at the and lead author of the study, emphasized that “there are a variety of ways to engage youth and reduce their risk of overdose. Schools, places of employment, homeless shelters, child welfare services, and juvenile justice settings are all possible touchpoints to offer education and harm reduction tools such as naloxone and fentanyl test strips. Our findings highlight the need to tailor these strategies to different youth groups based on the types of drugs they are using to help prevent further overdose deaths.”

Limitations to the study findings, according to the investigators, include possible misclassification in mortality coding practices, as well as limited sociodemographic information. For example, youth who identify as LGBTQ+ tend to have a higher risk of overdose, yet that information was not available. Due to small sample sizes, the data did not examine youth who may identify as more than one race or ethnicity.
