And what Id love to do is eliminate fentanyl deaths in the state of Oklahoma, Hilbert said.As filed, Leos Law gives the Department of Human Services a roadmap for dealing with parents suspected of drug use. In simplest terms, the law would require DHS officials to conduct a thorough investigation, upon a tip of possible drug use. The plan starts with giving parents the option for a drug test. If the parents refuse, the legislation instructs investigators to get a warrant for the drug test. and proceeding from there.It also creates a felony, in state law, for knowingly exposing a child to fentanyl, Hilbert said.SEE FOR YOURSELF >>> Click here to read HB4421Towe made dozens of calls, held several rallies, and advocated for other families grieving drug deaths.
