Drug Trends in the Teenage Postmortem Population From 2017 to 2021.

Abstract: The teenage population is highly vulnerable to drug exposure, use, and misuse due to the physical and emotional development that occurs at those ages. Social influences, like the isolation experienced during the COVID-19 pandemic and social media, can exacerbate this vulnerability. To better understand the potential impact of these influences on teenage drug use, postmortem results reported by a large reference laboratory from 2017 to 2021 corresponding to the teenage population were evaluated for various drugs of misuse. These data revealed a marked increase (385%) in reported fentanyl cases and a 13% increase in positivity rate. Methamphetamine- and cocaine-positive cases also increased 126% and 54%, with a net percent positivity of +0.6% and -0.5%, respectively. Conversely, heroin showed a consistent decline in reported cases (67%) and a net decrease of 1.0% in positivity rate. In addition to commonly misused drugs, trends for other substances that are prevalent in social media and therefore may disproportionally impact teens, MDMA/MDA, mitragynine, and diphenhydramine, were also assessed. A discussion of drug-related social media trends is presented to provide additional context for the data and trends reported herein, ultimately creating a framework through which social influences on teenage drug use can be better understood.
