Changing laws about a 14 teen year old child having to sign for mental health treatment

Minor children of the age 14 teen and older have the right to make decisions about their mental health treatment and if the child does not want to get such treatment you as the parent cannot force them to receive it. I understand that children need to start making some decisions at some point in time when it comes to their health us as parents need to keep our children safe. Most people that have a mental health issue do not know that they have such an issue and if you add drugs into the factor then they really can't make a reasonable decision on their mental health. My son is 16 teen years old, about the age of 14 teen he started to get into trouble with the law and was doing drugs here and there. I tried to get my son the help that he needed but because he was 14 teen I could not.
