May 22, 2026, update: We publicly shared this resource on April 20, 2026. Since that time, we have welcomed and received feedback from our drug checking colleagues, as well as from some of the technology developers. We anticipate receiving additional feedback over the coming weeks.
Our team will carefully review all comments and, where appropriate, incorporate refinements that help clarify our work and improve the presentation of our findings for community drug checking service providers. An updated version of this resource will then be circulated, with any revisions clearly identified and summarized.
If you have any questions, comments, or feedback about this resource or our program, please contact hello@drugchecking.community.
