Políticas de etiquetado en los paquetes de cigarrillos: situación actual en América Latina y el Caribe Ernesto M Sebrié Salud políticas públicas Comunicación en salud legislación sanitaria envasado de productos derivados del tabaco etiquetado de productos derivados del tabaco En 2002, Brasil se convirtió en el primer país de la región en implementar etiquetas de advertencias sanitarias con pictogramas en los paquetes de cigarrillos. Desde la adopción del CMCT de la OMS en 2005, otros nueve países adoptaron advertencias con pictogramas y seis más aprobaron legislación cuya implementación está pendiente. El contenido del mensaje y el estilo del pictograma varían entre los países. Diecisiete países prohibieron descriptores de marca y nueve requieren una advertencia cualitativa con información de constituyentes y emisiones. Un importante progreso se ha alcanzado en la región desde 2005. Sin embargo, los países ratificantes del CMCT aún no han implementado todas las recomendaciones de las Directrices del Artículo 11. 2012 artículo científico 0036-3634 https://www.redalyc.org/articulo.oa?id=10623059012 es http://www.redalyc.org/revista.oa?id=106 Salud Pública de México application/pdf Instituto Nacional de Salud Pública Salud Pública de México (México) Num.3 Vol.54
