My question involves juvenile law in the State of: Arkansas

Can a minor be screened for drugs without the consent of the parents? Also, if a minor is found in possession of drugs at the hospital and then the drugs are transferred to the police, can there be charges brought against the minor? What if the minor swears he/she cannot remember having drugs on him/her or even doing the drug? Are there foods that can result in false positives for certain drugs? I know a person who eats food with poppyseeds can test positive for opium.
