The Kid PROOF Act of 2023 expands federal grants that help prevent suicide and overdose deaths among children, adolescents, and young adults. The bill amends existing law to allow grant money to be used for suicide prevention services in addition to substance abuse treatment, and broadens the types of organizations eligible to receive funding to include pediatric healthcare providers, children's hospitals, emergency departments, and Indian Health Service programs. New grant money can support parent counseling on overdose and suicide prevention, as well as supplies to help prevent access to lethal means. The bill extends the authorization period for these grants from 2023 through 2028 and requires that at least $2 million per year be allocated to the expanded grant programs, though the total funding amount is not specified in the legislation.
