The General Assembly finds and declares that a substantial drug and alcohol trafficking and abuse problem exists in this State among school age children, in schools and on school campuses, parks and playgrounds. It is the purpose of this chapter to support increased efforts by local law enforcement agencies, working in conjunction with school districts and with state and local drug and alcohol prevention agencies, to suppress trafficking, and to prevent drug and alcohol abuse among school-age children in schools and on school campuses, through the development of innovative and model programs jointly undertaken by local law-enforcement agencies and school districts. Further, it is the intent of the General Assembly to establish a program of financial and technical assistance for local law enforcement and school districts, and to formulate a joint policy of pursuing both demand reduction (through education and prevention programs), and supply reduction (through law enforcement).
