--> In light of these concerns, Roberts devoted his lengthiest analysis to the government's "important — indeed, perhaps compelling interest" in deterring drug use by students. To this point, the opinion cited statistics illustrating the problems of youth drug abuse. It further noted that part of a school's educational mission is "to educate students about the dangers of illegal drugs and to discourage their use". The District Court also noted "peer pressure is perhaps 'the single most important factor leading school children to take drugs.'" The Court's interpretation of Frederick's banner deemed the banner as a type of peer pressure. Based on these concerns, the opinion concluded that the principal's actions were motivated by a "serious and palpable" danger of drug abuse quite different from the amorphous fears of anti-war sentiment at play in "Tinker".
