Social Anxiety and Alcohol Use

"Alcohol is, by far, the most widely used drug among college students, with 60.8% of students reporting alcohol use in the past month (Substance Abuse & Mental Health Services Administration, 2012). In 2009, 61.5% of college students reported that they had been intoxicated at least once in the past year, with 42.4% reporting that they had been intoxicated in the past 30 days (Johnston, O'Malley, Bachman, & Schulenberg, 2010). Approximately 37 to 44% of college students reported that they binge drank at least once in the past two weeks to month (Hingson, Heeren, Winter, & Wechsler, 2005; Johnston et al., 2010; Wechsler et al., 2002).

"Alcohol use can lead to a wide range of problems (e.g., involvement in risky sexual situations, driving under the influence, hangovers, nausea and vomiting, and aggression). Due to the high levels of alcohol consumption and the contexts in which college students typically consume alcohol (e.g., parties where excessive drinking is the norm), along with no parental oversight and monitoring, this population may be particularly likely to experience alcohol-related problems (ARPs). Of college students who drank at least once per week during their first year of college, 80% experienced more than one ARP during their first year, and 34% reported that they had experienced six or more ARPs during that time (Mallett et al., 2011)."
