The recent upswing in both licit and illicit drug use by adolescents in Nova Scotia, documented in this issue by Drs. Christiane Poulin and David Elliott, is justifiable cause for concern. Of the students surveyed on their drug use in the preceding 12 months, 37% had used no alcohol or other drugs, 22% had used all of alcohol, tobacco and cannabis, 27% had experienced at least 1 alcohol-related problem and 6% had experienced at least 1 other drug-related problem. These findings, along with the results of other research,' demonstrate the need to minimize the risks of nonmedical drug use by adolescents. They also raise questions about the role of school-based drug education. Why aren't current programs more effective? What alternative strategies might be deployed? Would programs based on the principles of harm reduction be more effective, as Poulin and Elliot suggest?
Harm-reduction interventions focus on mitigating the harmful consequences of substance use rather than on eliminating such use altogether. Implicitly and explicitly, they accept the existence of a range of drug use patterns along a continuum of risk. Consensus has emerged with respect to the following premises of harm reduction: (2)
• nonmedical use of psychoactive drugs is endemic in modern societies,
• nonme`dical drug use produces varying degrees of social and personal harm,
• policies and programs to reduce harm must be judged by their impact, not
• the health of drug users and the community is best served by an approach that
integrates rather than isolates the drug user,
• the complex relation between drug use and harmful outcomes necessitates
Although harm reduction has gained credibility in specific areas (e.g., needle exchange programs) it is still controversial when applied to drug education. A number of educators have articulated a framework for a harm-reduction approach to drug education.3 4 Their point of departure is to accept the principles of harm reduction and apply them pragmatically, offering education about drug rather than against drugs. The goal is to provide accurate and credible information that will promote responsible behaviour. This approach acknowledges the appeal of drug use from the young person's perspective as well as its potential medical, social and legal consequences. It is rooted in an appreciation of adolescent psychological development in which curiosity, a willingness to experiment and the definition of personal boundaries come into play. Thus, the more general educational aim of developing the young person's capacity for autonomous decision-making is extended to the issue of drug use.
Traditional programs attempt to prevent drug use by emphasizing its negative aspects. They present non-use as normative and equate use with abuse. The effectiveness of such programs has not been demonstrated. DARE (I)rug Abuse Resistance Education), a police-delivered program widely used in the US and Canada, has been tracked and evaluated by several investigators, all of whom have concluded that it has no long-term effect on behaviour.4 5 A comprehensive literature review of school-based programs reached similar conclusions about the effectiveness of the conventional approach.6 The recent upswings in adolescent drug use are further evidence of failure.
Some researchers have suggested that school-based prevention programs cannot be effective because they are inconsistent with the messages that adolescents receive from the larger social environment. Some have concluded that it is unrealistic to expect these programs to prevent or change adolescent drug use and have proposed more realistic goals, such as promoting safer use, delaying use, preventing the escalation of use and encouraging users to take responsibility for themselves and others.
Some critics of drug education geared solely to prevention have suggested that it may actually be harmful.7 8 First, they argue that an emphasis on abstinence as the norm isolates and stigmatizes young people who are using drugs and may reinforce other forms of deviance. Second, they argue that those who are experiencing problems may be deterred from seeking help.9 Third, they assert that it is questionable whether anti-drug programs equip young people for life in the real world, where even those who do not use drugs may need to assist and understand people who do. Fourth, they argue that drug education programs can undermine the authority of classroom teachers by relying on police officers, former addicts and sports figures to recount sensational stories of drug abuse.
Critics of the harm-reduction approach warn that it may increase drug use by portraying its attractions and making it seem acceptable or even expected. They argue that the risks are too great to experiment with such programs without evidence of their efficacy and that, at most, harm reduction may be appropriate for young people who are already heavily involved in drugs 10. Some argue that anything but a strict abstinence message may be viewed a surrender in the war on drugs. Such a view is epitomized in the statement by Robert Dupont, White House drug "czar" under US presidents Ford, Nixon and Carter, that teenagers "need to know that drug use is unacceptable and will be punished, . . . including [the use of] alcohol and tobacco" 11. This approach is also reflected in the remark by Barry McCaffrey, director of the US Offfice of National Drug Control Policy, that the administration's stand against the medical use of marijuana is intended to "[protect] the scientific process and youth."'2
While the dust swirls over the ideological debate as to who should control what is taught in our schools, Poulin and Elliot are correct to ask whether the time has come to change our reliance on prevention-based drug education. The proponents of harm reduction argue that the prevailing absolutist perspective ignores reality. The wide availability of licit and illicit drugs is a fact of modern life that has not been altered by devoting vast amounts of money to law enforcement. Many adolescents will not try drugs, many will experiment without adverse effects and some will use drugs in amounts or situations that lead to serious harm. We must seriously consider introducing new health- and safety-oriented programs that have the potential to reduce these harms. Society does adolescents a disservice by not equipping them for the challenges of-a world in which legal and illegal drugs are omnipresent.
Of course, the harm-reduction approach to drug education cannot be systematically evaluated until pilot projects are in place. The priority should be to fund and implement such efforts, building on existing groundwork. Educators who favour the harm-reduction approach have already developed core materials and a framework for curriculum development.34 The aims of any program must be clearly stated, realistic and measurable, and the ultimate test must be that of effectiveness. There will be more than 1 way to measure success in reducing harm, and to do so objectively will be essential. Despite the dismal record of conventional programs in preventing drug use, few have been assessed in terms of their ability to reduce harmful outcomes. Among the array of programs that have been tried, it may be possible to identify particular features that show more promise for harm reduction than for outright prevention, as well as characteristics that may actually promote harm.13
Prevalence rates should not be ignored as an indicator of harm reduction, but they must be kept in perspective. An upswing or downturn in use tells us nothing about patterns of harmful use; more significant indicators are rates of heavy use and of polydrug use.
There is no reason to suppose that a well-integrated curriculum, rooted in an understanding of psychosocial development, cannot be effective in supporting choices to refuse or delay the use of drugs. Moreover, public acceptance of the harm-reduction approach will require that non-use be included as 1 of several viable goals.
Finally, we should remember that another approach to prevention is widely applied in Canada, namely, the criminal prosecution of drug users. Despite the lack
of evidence of any deterrent effect, the current law threatens the 1 in 4 adolescents who try cannabis with criminal records and potential imprisonment. This threat is not hollow: several thousand young people are charged annually.l4 In trying to prevent or reduce the harm of adolescent drug use we must consider the difficulty of reconciling the punitive policies of our criminal justice system with the aims of educational programs that are concerned with the wellbeing of youth.
Effective strategies do not emerge in isolation, but blend health services, education and law enforcement to a common purpose. The evolving harm-reduction model can provide a pragmatic and flexible response to the problem of adolescent drug use.15 It is time for harm-reduction education programs to be given the opportunity to demonstrate this.
