We detected extensive underreporting of ketamine use with prevalence of use nearly tripling when considering both self-report and detection in hair samples. Intentional underreporting of drug use is common, but underreporting in this population is higher than expected considering self-reported use of synthetic drugs was common. Since it is unlikely that a participant would report use of drugs such as ecstasy and intentionally underreport ketamine use, we believe many cases of positive detection may be due to unknown exposure through use of adulterated drugs.
