What's in the US drug supply?

This app is in beta testing and lists which substances we have detected in street drugs at the UNC Street Drug Analysis Lab. It also tells you which other substances were found along with a given substance. We list which states the substance has been detected to provide a broad sense of distribution.

🏷️ Two things of Note: We get more more samples from NC, WA, NY, CA, and MI than other states. Geographic data below should not be construed as prevalence. And people may preferentially send us samples because they caused unusual reactions. There is no possible data source on street drugs that is fully generalizable. Got it? Okay!

Example Samples

View up to 5 random samples containing the selected substance. Substances may have been detected in primary or trace abundance.

Methods

We obtain drug samples from 140+ harm reduction programs, clinics, hospitals, EMS, health departments, and drug user unions in 35 US states, covering about 200 counties. Samples are donated voluntarily, and collected anonymously. Mailed-in samples are analyzed using exactive (high resolution) GCMS, with untargeted search, and pure standard verification of identified substances. See laboratory methods and codebook and GitHub repo for code and dataset, and further details.
