A mom in the South Valley is under arrest.
The Terra Bella was taken into custody after her 1-year-old child tested positive for pot.
23-year-old Nikki Ray took her baby to the hospital for a fever but tests showed large amounts of THC in the child's system. THC is the main chemical in marijuana.
Deputies say Ray is a medical marijuana user and often smokes it around her one and three-year-old children.
Her children are now with Child Protective Services.
