WOODBURY — High school students know it’s coming every year, and many of them roll their eyes when it comes time to listen to another guest speaker talking about substance abuse.

Those in the local community, such as Nonnewaug principal Pam Sordi, find these assemblies useful. She praises the school district’s partnership with Advocates for Substance Abuse Prevention (ASAP), a group that has adjusted its approach to starting awareness campaigns in elementary school. Still, there’s no one-size-fits-all approach to combating youth substance abuse.
