I work with a number of parents within my area, and that's reflective of the coordinators across the nation. They are entitled to access services as long as they're required, just as the other people who are accessing the program are. The nature of what they're seeking support for is individual. Some of them might want to understand possible signs and symptoms, or how they can support their loved one and help them through the recovery process.
I want to reiterate what Kathy said, that the program doesn't turn anyone away. Essentially, whether it's a best buddy or a grandmother or a parent or a sibling, we'll provide support to them, however they may require it.
