Urinary and salivary cotinine quantify individual tobacco exposure, but no analogous, objective metric exists at the community level. Wastewater-based epidemiology (WBE) has transformed surveillance of infectious diseases and illicit drug use; whether the same approach can yield a community-level signal of CVD risk is unknown.
