This study reports the findings of a field trial designed to assess th
e extent of alcohol sales to minors in one county in northwest New Jer
sey. Two 19-year-old males were successful in purchasing alcoholic bev
erages in 27 of 46 (58.7 percent) establishments visited. On the follo
wing day, 23 of the establishments that sold the alcohol were visited
again and on this occasion, 18 (78.3 percent) sold alcohol to the mino
r. This study supports the findings from surveys that show that undera
ge drinkers can obtain alcohol with ease. Many community groups are no
w taking action to rectify this situation, and data of the type report
ed in this paper can be used to assess the effectiveness of their acti
ons.
