232.107  Parent visitation.
  If a child is removed from the child’s home in accordance with an order entered under this division based upon evidence indicating the presence of an illegal drug in the child’s body, unless the court finds that substantial evidence exists to believe that reasonable visitation or supervised visitation would cause an imminent risk to the child’s life or health, the order shall allow the child’s parent reasonable visitation or supervised visitation with the child.
