A pilot study in Mexico is showing promising results for measuring the frequency and type of drugs being used across the country by measuring metabolites in wastewater.
Researchers from Mexico’s National Institute of Public Health (Instituto Nacional de Salud Pública — INSP) took samples of metabolites — leftover traces of drugs that end up in human waste — across 13 cities, especially in the sewage systems of addiction treatment centers, prisons and high schools.
And guess what? Mexico came up dirty.
What a surprise.
