Contamination of Young Children Hair During Acute Cannabis Intoxication

Hair analysis in pediatric cannabis intoxication is limited by possible sudoral self-contamination, especially in young children due to hair porosity. However, adult studies show no THC-COOH in sweat, challenging this hypothesis. THC-COOH presence in sweat has to this day never been studied in young children. Its absence would help assess the reliability of hair testing for prior exposure. Thus, our main objective is to describe whether THC-COOH can be detected in sweat following cannabis intoxication using gold standard techniques.
