Mexican immigration to the U.S. and alcohol and drug use opportunities: Does it make a difference in alcohol and/or drug use?

摘要

BackgroundMexican immigrants in the US do not have increased risk for alcohol use or alcohol use disorders when compared to Mexicans living in Mexico, but they are at higher risk for drug use and drug use disorders. It has been suggested that both availability and social norms are associated with these findings. We aimed to study whether the opportunity for alcohol and drug use, an indirect measure of substance availability, determines differences in first substance use among people of Mexican origin in both the US and Mexico, accounting for gender and age of immigration.
