Antecedentes y Objetivos Aunque existe una abundante cantidad de datos sobre el consumo de alcohol a nivel de población en países de altos ingresos, el panorama en África subsahariana ha sido mucho menos explorado. La falta de investigaciones exhaustivas en esta región limita la comprensión de los patrones de consumo de alcohol, así como de los trastornos asociados, lo que dificulta la implementación de políticas de salud pública efectivas.

There is also a concern that the initiation of tobacco smoking may increase the risk of using cannabis, given the common method of administration and the frequent co-use of these two substances among youth [3].
