More than 40 percent of the Nation's estimated 10.8 million underage current drinkers (persons aged 12 to 20 who drank in the past 30 days) were provided free alcohol by adults 21 or older, according to a nationwide report by the Substance Abuse and Mental Health Services Administration. The study also indicates that 1 in 16 underage drinkers (6.4 percent or 650,000) was given alcoholic beverages by their parents in the past month.  A copy of the study may be downloaded here.
