This research addresses the impact of illicit drug use on labour market outcomes of men in Mexico. We leverage statistical information from three waves of a comparable national survey and make use of the Lewbel’s heteroskedasticity-based instrumental variable strategy to deal with the endogeneity of the drug consumption. Our results suggests that drug consumption has fairly negative effects in the Mexican context: it reduces employment, occupational attainment and formality and raises unemployment of local males. These effects seem larger than those estimated for high-income economies.
