Immigration may influence alcohol consumption and its consequences in at least two ways. The first theory suggests that immigrants encounter difficulties and hardships as they transition into a new society and culture (Berry 1997). Hardships include the stress of experiencing new environments and cultures; living in poor neighborhoods; finding good, secure jobs in safe work environments; encountering few opportunities to enhance income or wealth; and engaging with fewer and smaller social networks that may otherwise offer instrumental and emotional support. It also is possible that immigrants may not become fully integrated into American society because of experiences with discrimination and obstacles in social mobility (Unger et al. 2014). Because these factors are associated with alcohol consumption and problems, immigrants may consume more alcohol (Unger et al. 2014). As they become settled in the new society, this consumption pattern decreases (Bui 2012). A second hypothesis posits that alcohol consumption increases the longer immigrants live in a new location (Lee et al. 2013). Over time, immigrants may learn the behaviors and adapt the lifestyles often associated with alcohol consumption in American society (i.e. experience acculturation) (Caetano 1987; Vaeth et al. 2012).
