OKLAHOMA CITY - A new law allowing drug testing for certain welfare applicants goes into effect on Thursday.

Governor Mary Fallin signed House Bill 2388 into law back in May.

Under the new law, the Department of Human Services is required to screen adults who apply to the "Temporary Assistance for Needy Families" program. Anyone who fails or refuses the drug test will be denied benefits.

Applicants who test positive for illegal drug use and undergo substance abuse treatment can reapply for benefits six months after the date of their denial. Child-only cases and underage parents would be exempt from drug screenings.

The bill also allows for an alternative payee to be named when a parent has been denied benefits.
