You’re reading this wrong. Minors have a right to consent to mental health services on their own. The law doesn’t prevent parents from seeking mental health services for their children. Parents are allowed to be involved in the mental health treatment of their children, but “medical records” are confidential, even from parents. This might be a good thing, considering some parents are abusive, and the patient needs to trust the therapist enough to talk to them honestly.
Drug/alcohol treatment — minors don’t have a right to refuse if parents consent. However, confidentiality laws still apply. This is a good thing, see above.
This law also protects minors and allows them to get birth control, have abortions, get STD/HIV testing, get STD treatment, get prenatal care, all without a parental unit’s consent. Again, a good thing considering how hateful and abusive some so-called religious/conservative parents can be.
Read the link before whining so much. I bet you don’t listen to your kids either.
