摘要:We estimated the proportion of the nation’s public school districts that have high school grades in which random drug testing is conducted. We collected data in spring 2005 from 1343 drug prevention coordinators in a nationally representative sample of school districts with schools that have high school grades; of these districts, 14% conducted random drug testing. Almost all districts randomly tested athletes, and 65% randomly tested other students engaged in extracurricular activities; 28% randomly tested all students, exceeding the current sanction of the US Supreme Court. Student drug testing on a suspicionless or random basis is currently sanctioned by the Supreme Court for students participating in extracurricular activities 1 , 2 and is supported by the Office of National Drug Control Policy. 3 , 4 Although supporters of the strategy argue that it deters students’ initial use, has beneficial consequences for the early detection and treatment of drug use, and provides students with a rationale to decline use, 3 , 4 the strategy has generated considerable controversy. 5 – 11 The proportion of the nation’s high schools conducting random drug testing is not known. We estimated the national prevalence of random drug testing in public school districts that include high school grades and specified which populations of students were eligible for random drug testing.
