Table 1 describes the combined NLAES/NESARC samples. Subjects ranged from 20 to 44 years old at the time of the NLAES interview, and from 30 to 54 years old at the time of the NESARC interview. 10.3 % of the sample met DSM-IV criteria for past-year alcohol use disorder, 1.5% met criteria for past-year marijuana use disorder, 1.7% for other illegal drug use disorders, and 11.3% met DSM-IV criteria for any past-year alcohol or other substance use disorder. 51.8% of the full sample and 78.2% of the age-restricted sample would have been legally allowed to purchase alcohol before the age of 21.
