Blood ethanol concentrations were significantly higher for periadolescent rats. Following three weeks of consuming an ethanol-containing liquid diet, Long-Evans and Sprague-Dawley rats which began diet consumption as preadolescents at postnatal age 25–28 days (P25–28) or as adults (P75 or greater) were sacrificed, and blood ethanol concentration (BEC) was determined in trunk blood and presented as mean ± SEM. *For each strain, there was a highly significant difference in BEC between the periadolescent rats and adults (P = 0.003).
