Hi what can i do if cps is demanding a drug test from me, all because the school principle at my 16 yr old daughters school was concerned about her bad grades and the crowd she hangs with and thought it may be an issue at home. I am a good mother and care for my daughter the best i can, she is rebelling a bit which i believe to b normal. I dont get why i should have to do anything cps demands of me. What can i do?
