Looking for a Caregiver Involved With Teenage Drug Abuse for a Quick Telephone Interview?

The title explains it all.
I know there are a lot of numbers you can call to get help with drug abuse, but I’m just looking for info. This is for a school project, and so far I haven’t been able to contact anyone who simply gives out information on what they do to help prevent teenage drug abuse.

I’m looking for a phone number to call preferably.
