I think there has to be open communication. There have to be harm reduction conversations, rather than vilifying harm reduction as a bad thing. Harm reduction doesn't make people use more drugs; it just makes them educated about how to protect themselves.
Another big thing for youth would probably be drug checking.
Have open, educational conversations with parents so they understand that kids will use drugs. There's no way we're going to stop that from happening, so we need to have an educated approach for both parents and youth in order to understand how to best protect them if they're going to use substances of any kind.
