Editorial: Inconclusive (or "Elusive"): Concordance Between Substance Use Self-report and Toxicology for Diverse Youth Populations.

ABSTRACT

Adolescent substance use is an important public health issue, with 15% of eighth graders (ages 13-14) reporting past-year cannabis use, 26% reporting alcohol use, and 23% reporting vaping nicotine in recent national surveys.1 Among youth and young adults in need of mental health services, co-occurring substance misuse is a topic of particular importance. This is particularly evident in special populations, such as youth in juvenile detention, youth living in rural communities, and youth in residential or foster care. Accurate drug use identification is necessary to determine substance use needs and sequelae in youth. Ideally, this is accomplished through a combination of self-report and toxicological biospecimen analysis, such as the use of hair toxicology. Yet, the consistency between self-reported substance use and robust toxicological analysis is understudied and has not been researched in large, diverse samples of youth. This has implications for both public health research and clinical practice. Of particular importance for research on health disparities in substance abuse problems and treatment is the likely possibility that reporting validity often varies by race/ethnicity and by other important subgroupings.
