Drug education programs focusing on information and refusal skills significantly reduce youth drug use.

In September 1983, the Los Angeles Police Department and the Los Angeles Unified School District launched a joint program that would become the most widely adopted drug prevention initiative in American history. DARE, Drug Abuse Resistance Education, placed uniformed police officers in fifth and sixth grade classrooms for seventeen weekly sessions. Officers taught students to identify drugs, resist peer pressure, and build self-esteem. By 1996, DARE operated in 75 percent of American school districts. The surgeon general endorsed it. Congress protected its federal funding. Elementary school hallways filled with red DARE t-shirts and stickers showing a cartoon lion refusing a joint.

The theory behind DARE was intuitive and compelling: young people used drugs because they didn't know the risks and couldn't resist pressure from peers. Provide the information and the refusal skills early enough, and the behavior would change. The delivery mechanism, trusted authority figures in uniform, in classrooms, with parental approval, seemed optimal.

The evidence arrived before the program reached its peak popularity, and it was consistently negative.

In 1994, Susan Ennett and colleagues at the Research Triangle Institute published a meta-analysis in the American Journal of Public Health examining eight prior evaluations of DARE. The findings were blunt: DARE produced a statistically marginal effect on drug use, a weighted mean effect size of 0.06, essentially indistinguishable from zero. A long-term follow-up study tracked students through high school and found the effects had completely vanished. By late adolescence, students who had completed DARE were no more likely to be drug-free than those who hadn't.

Subsequent large-scale evaluations replicated these findings. The United States General Accounting Office reviewed six long-term studies in 2003 and concluded that students who participated in DARE had no statistically significant differences in illicit drug use. The surgeon general classified DARE as an ineffective program. SAMHSA removed it from its list of evidence-based substance abuse programs.

What had gone wrong? The theory of change turned out to be wrong. Drug use in adolescence is driven primarily by social context, family environment, poverty, and mental health, not by information deficits or weak refusal scripting. Knowing that heroin is harmful does not meaningfully change the probability that a teenager in a difficult environment will try it. And the specific format of DARE, lecture-style delivery from authority figures to elementary students, bore little resemblance to the interactive, skills-based programs that actually showed effects in controlled studies.

DARE's survival despite the evidence was political, not scientific. Police departments had invested institutional identity in the program. Parents felt reassured. Elected officials didn't want to be seen defunding drug prevention. Congress inserted protections for DARE funding into federal education budgets even as researchers uniformly concluded the program didn't work. DARE America reportedly spent money trying to prevent distribution of the Research Triangle Institute report.

The organization eventually reformulated its curriculum in 2009, shifting to a more interactive format. But for the better part of two decades, tens of millions of American schoolchildren sat through a program whose ineffectiveness was documented in peer-reviewed literature while it was still expanding, a case study in how political and institutional inertia can insulate an educational intervention from its own evidence base.
