My 17 year old daughter admitted she's using speed. I'm am ex user, so I already had plenty of suspicions. She lives with her dad, I have no custody. He recreationally uses, and would probably not believe me even if I told him. I do not expect any support from him or anyone from that side of her family, most of them use something, from grandma the nurse who shoots pain pills, to uncle who does speed and pills, to dad who smokes weed, drinks, and gets high sometimes. I cannot afford to pursue custody at this time. I'm considering putting a tracker in her car, finding where she's getting it, them reporting all of them to the cops. Better a juvie record than a prison record, right? Help! I need suggestions!
