Full report: Drug Testing in Schools: Evidence, impacts and alternatives. Ann Roche, Ken Pidd, Petra Bywood, Vinita Duraisingam, Tania Steenson, Toby Freeman, Roger Nicholas We attempted to synthesise a diverse array of complex, conflicting and sensitive information in a balanced manner.
Comprehensive coverage of relevant issues 1.available data on drug use by school-aged children and, in particular, high- risk groups 2.evidence of the effectiveness of biometric and psychometric tests 3.evidence on the effectiveness of tests to deter or reduce drugs and any associated potential adverse outcomes 4. 5.cost implications of the implementation of various forms of testing 6.ethical, legal and practical implications of testing school-aged children 7.incorporated the views and perspectives of professionals, parents and community members through a submissions process and an online survey 8.addressed the range of alternative strategies available to tackle drug use among school-aged children and the evidence base of effectiveness.
A Public Health Model The public health model applied in the present review involved: assessing the epidemiology of a targeted problem (i.e. patterns and prevalence of use) identifying risk and protective factors associated with the development of the problem applying interventions known to reduce these risk factors and enhance protective factors that buffer against the effects of risk monitoring the impact of these interventions on the incidence and prevalence of the targeted disease and disorder (Hawkins, Catalano & Arthur, 2002).
Aims/rationale for drug testing Drug testing is sometimes viewed as an appealing strategy to deal with drug use among school-age children as it is assumed to: –deter initiation of drug use and encourage cessation –detect users in order to refer them to treatment/counselling –reduce drug-related harm by improving young people’s physical and psychological wellbeing, reduce truancy and behavioural problems, and improve educational outcomes.
What drug testing does not purport to do provide a measure of intoxication or impairment determine the quantity, frequency or context of drug use distinguish between experimental, occasional or one-off users and those with problematic drug use distinguish between similar metabolites found in over-the-counter or legally prescribed medications and illicit drugs.
1. Approaches to drug detection and screening There are a number of different approaches that can be employed to address the use of drugs in a school environment. These include: 1. biometric measures of drug use (e.g. biological assays of urine, saliva, sweat, hair) 2. psychometric measures of drug use (e.g. self- report survey, questionnaires or interviews) 3. devices for detection of drugs or drug paraphernalia (e.g. sniffer dogs, search of lockers or belongings).
Assumptions underlying drug testing Assumption #1 Criminological theory and the power of surveillance Surveillance is used as a tool for social control. If their behaviour is open to scrutiny, young people will avoid deviant acts (Foucault, 1980). Limitations Surveillance alone is inadequate unless accompanied by: Social consensus about what defines deviant behaviour Drug testing will reduce drug use only if young people believe they will experience stigma or negative consequences of their drug use if discovered. Individuals with pro-drug attitudes and little respect for societal norms are less likely to reduce drug use and may view a positive drug test as status. Capacity to apply negative sanctions or punishment Without a negative sanction (e.g. exclusion, punishment from parents), drug testing is unlikely to deter future use. For example, athletes may view exclusion from competition as undesirable, but schoolchildren may welcome exclusion from classes. Capacity to handle concealment (e.g. masking) Individuals may use masking agents, avoid providing a sample (e.g,. absence from school if they expect to be tested), or switch to less detectable, and potentially more harmful, drugs or alcohol.
Assumptions underlying drug testing cnt. Assumption #2 Early identification and intervention Identification of drug use at an early stage may reduce the likelihood of developing into a drug ‘problem’. Limitations Teenage drug use does not lead inevitably to problematic drug use. While screening is sensible for health issues that predictably lead to deterioration (e.g. cancers), this is not so for teenage drug use. The relevance of early identification applies only to a very small number of students
Assumptions underlying drug testing cnt. Assumption #3 Capacity to bolster resistance to drugs Drug testing programs give students a reason to say ‘No’ when they encounter drug use. Limitations Routes to drug use differ. Not all young people are pressured by their peers to start using drugs. Young people may also select their friends on the basis of similar interests, including drug-using behaviour.
Prevalence of Drug Use Declining Between 1996 and 2005 there was a significant decrease in cannabis use by 12-17 year olds (the most commonly used illicit drug among this age group). (e.g. lifetime use for 12-15 year olds in 1996 28% adn 13% in 2005. Among 16-17 year olds 52% vs 31%).
Effectiveness of tests Sensitivity (>90%) Specificity (>90%) Accuracy (>95%) Standard tests would result in a minimum of 10% false positives
Cost Urine Universal $302Mil Random sample $91mil Targeted groups $47.9mil For cause $11.7mil Saliva Universal $355Mil Random sample $110mil Targeted groups $58mil For cause $15.9mil
Effectiveness in Deterrence Little evidence to support it Eg., Yamaguchi´s study of 323 schools and 94,000 students
Potential Adverse Consequences Breakdown in parent- child and/or school-child relationship stigamisation Increase in school exclusions or truancies Reduced participation in healthy extracurricular activities Diversion to other substances not tested for, or less detectable Unwarranted invasion of privacy Breach of confidentiality False sense of a drug-free environment Lack of developmentally appropriate adolescent treatment/interventions after testing positive School time and resruoces used on drug testing, incl. Opportunity costs Ambiguous role for schools Penalities for drug use imposed on schools
Ethical and Legal Issues Duty of care Right to bodily inviolability Right of the child Drug testing as a deterrence strategy Similarities and difference with Workplaces and workplace testing
Ethical Perspectives Principalist Theory of Ethics Employs values such as: oRespect for persons oJustice oBeneficence Consequentialist Ethics Justifications based on consequences, not principles
1. 4 major motivations underlying the development of drug use problems 1. To escape developmental distress. 2. To self-manage body and spirit. 3. To conform to social norms. 4. To create individual identity.
Drug use problems are not wholly influenced by individual choices. They are also shaped by a range of macro- economic factors, including the economic, social and physical environment. “Trying to shift the whole responsibility on to the user is clearly an inadequate response. This blames the victim, rather than addressing the complexities of the social circumstances that generate drug use. Effective drug policy must therefore be supported by the broad framework of social and economic policy” (Wilkinson and Marmot (2003;p.25).
Alternative, evidence-based roles for schools 1.Support and foster connectedness between school and students 2.Provide targeted early and brief interventions 3.Õffer family strengthening interventions
