Wastewater-based epidemiology (WBE) has become a very useful tool to monitor a
population’s drug consumption or exposure to environmental and food contaminants. In this
work, WBE has been applied to estimate tobacco consumption in seven Spanish regions. To
this end, 24 h composite wastewater samples were taken daily for one week in 17 wastewater
treatment plants, covering altogether a population of ca. 6 million inhabitants. The samples
were treated by enzymatic deconjugation and the wastewater content of two human-specific
nicotine metabolites (namely, cotinine and trans-3′-hydroxycotinine) was measured to
estimate the daily consumption of nicotine. The population-weighted average nicotine
consumption in the seven analyzed regions was 2.2 g/(day∙1000 inh.), without any daily
pattern. This average estimated nicotine consumption value agreed with the value derived
from official tobacco sales data. Differences in consumption among the seven studied regions
were found, being Galicia, the region with the lowest rate, and the Basque Country and
Catalonia those with the highest rates. However, no conclusive correlation was found
between those values and the prevalence data taken from two different national surveys, nor
sociodemographic and health data. This study demonstrates that this tool can complement
other indicators in order to accurately assess tobacco consumption rates at regional and
national levels and provides the most extensive application of the approach in the Spanish
territory. [-]
