Changes in concentrations of Tobacco Specific Nitrosamines in saliva in the general population of Barcelona before and after implementation of tobacco control legislation
Puntos clave
The study aims to assess the impact of tobacco control legislation on salivary concentrations of TSNAs among smokers and those who quit.
Measured salivary concentrations of TSNAs before and after legislation implementation
Compared changes in TSNA levels between continuing smokers and those who quit
Salivary TSNA concentrations declined in individuals who quit smoking
Increased concentrations were observed in continuing smokers
Findings indicate the effectiveness of monitoring TSNAs for legislative impact assessment
Resumen
Concentrations of salivary TSNAs declined in those who quit smoking but increased for continuing smokers. Monitoring TSNAs in saliva is useful for assessing legislative impact.
