More than 1,000 new mothers in Idaho have been placed on a child-abuse registry after their newborns tested positive for THC, according to a new investigation by CBS News and The Marshall Project.
In some cases, mothers said the positive tests resulted from accidental exposure, legal products, or ma*****na use in states where it is legal.
