Where to the samples come from?

We obtain drug samples from nearly 200 harm reduction programs, EMS, clinics, hospitals, health departments, and drug user unions from 40+ states across the US. Mailed-in samples are analyzed using GCMS, with untargeted search, and reference (pure) standard comparison. See Laboratory methods and codebook for full details. Samples analyzed as "methamphetamine" are those samples where methamphetamine was detected in primary abundance (e.g., excluding only trace meth); an alternative way to analyze the data would be to use 'expected substance' (e.g., what it was sold as). Sometimes methamphetamine is intentionally and explicitly sold in conjunction with other substances, such as fentanyl, to make pre-mixed speedballs.
