PMH member Joanna Almeida published a study on differences in risk of substance use by generation and time in the US, in a special issue of Social Science & Medicine on Place, Migration and Health. The study examined adolescent alcohol, tobacco and marijuana use by generation/time in US among public high school students in Boston, MA. Dr. Almeida and her co-authors found that the prevalence of each substance use was lowest among immigrants who had been in the US <4 years, relative to 3rd generation, US-born youth. The authors suggest that while immigrant youth have a lower risk of alcohol, tobacco and marijuana use relative to their US-born counterparts, the protective effect of foreign nativity on alcohol use erodes much more quickly than for tobacco or marijuana. In addition, the effects of generation and time in US on substance use differed by gender and the particular substance in question.
