Self-reported substance use by patients arriving at emergency departments with acute recreational drug toxicity matches toxicological analysis best for heroin (86.1% agreement) and cocaine (74.1% agreement). Inhalants, poppers, and magic mushrooms were self-reported but never detected analytically. Immunoassays accurately identified methadone (100% agreement) and cocaine (95.5% agreement) but were less consistent for amphetamines (81.8% agreement). Mass spectrometry confirmed MDMA, amphetamine, methamphetamine, and new psychoactive substances in many cases where immunoassays were negative, and revealed multiple-substance use. Diagnosis of new psychoactive substance use relied primarily on self-report.
