DARE effectively prevents youth drug use.

In September 1983, the Los Angeles Police Department and the Los Angeles Unified School District launched Drug Abuse Resistance Education, DARE, a school-based anti-drug program that would become one of the most recognizable prevention efforts in the United States. Uniformed police officers entered fifth- and sixth-grade classrooms to teach children how to identify drugs, resist peer pressure, and make healthy choices. The idea was simple and politically powerful: if children were warned early enough, given facts about drugs, and taught refusal skills, they would be less likely to use drugs later.

The program spread with remarkable speed. By 1987, DARE was already operating in thousands of school districts nationwide. Nancy Reagan's "Just Say No" campaign gave it a ready-made slogan, President Reagan praised it, Congress steered federal law-enforcement money toward drug education, principals liked having officers in schools, and local police departments gained positive publicity. By the 1990s, DARE had reached millions of students and became a symbol of the broader belief that classroom drug education could prevent adolescent drug use.

The problem was that DARE became nationally entrenched before anyone had shown that it worked. Beginning in the late 1980s and early 1990s, researchers started applying controlled evaluations and longitudinal follow-up to the program. A 1991 study by Dennis Rosenbaum and colleagues found that students who completed DARE knew more about drugs, but two years later they showed no difference in actual drug use compared with similar students who had not taken the program. Knowledge had increased, behavior had not.

The most influential early synthesis came in 1994, when Susan Ennett and colleagues published a meta-analysis in the American Journal of Public Health examining eight methodologically rigorous evaluations of DARE. The weighted mean effect size for drug use outcomes was 0.06, essentially indistinguishable from zero. In other words, the program's measurable effect on whether students used drugs was so small as to be statistically insignificant. Ennett also noted that more interactive prevention programs, especially those involving peer practice and active skill-building rather than adult lecture, performed several times better, though even those effects were modest.

Long-term follow-up studies reinforced the same conclusion. Whatever small short-term changes DARE may have produced in attitudes or knowledge did not persist in a meaningful way into later adolescence. Students who had gone through DARE were, by high school, no more likely to abstain from drugs than comparable students who had not.

Federal reviews eventually caught up with the academic literature. In 2003, the U.S. Government Accountability Office reviewed long-term studies and concluded that DARE had no statistically significant effect on illicit drug use. Around the same period, the U.S. Surgeon General's office identified DARE as ineffective, and the program's reputation as an evidence-based intervention declined sharply among researchers and public health specialists.

Yet the program did not disappear when the evidence turned against it. DARE had become more than a curriculum: it was a civic ritual, a reassurance to parents, a public-relations asset for police departments, and a politically safe way for elected officials to claim they were fighting drugs. That symbolic value helped insulate it from negative findings long after the scientific consensus had formed. Several states and districts reduced or dropped the program, but many continued using it for years.

DARE later revised its curriculum in 2009, moving away from the classic lecture-heavy model toward a more interactive approach developed with academic input. Evaluations of the newer version were somewhat more favorable than those of the original program. But the central historical lesson remained unchanged: the classic DARE model, despite enormous popularity and institutional support, did not significantly reduce youth drug use. It became one of the clearest examples in modern education and public policy of a beloved preventive program achieving cultural success without demonstrating behavioral effectiveness.
