"The current research reinforces previous conclusions that SDT [Student Drug Testing] is a relatively ineffective drug-prevention policy (Goldberg et al., 2007; Sznitman, 2013a; Yamaguchi et al., 2003). On the other hand, interventions that improve school climate may have greater efficacy. Indeed, 'whole school' health promotion efforts and interventions that work with students, teachers, and parents to develop positive school staff–student relationships and promote students’ security have been found to reduce substance use (Bond et al., 2004; Fletcher et al., 2008).
"Certainly, schools are important as social and learning environments affecting not only academic achievement but also health behaviors. Young people whose relationships with their fellow students and teachers lack respect are more likely to initiate and escalate use of drugs, as evidenced in this and other studies (Fletcher et al., 2008) and to be subject to other mental health problems (Blum and Libbey, 2004; Catalano et al., 2004; LaRusso et al., 2008). Therefore, the potential consequences of poor school climates for young people’s health are far reaching and deserving of attention."
