IDYLLWILD, Calif. (AP) — Authorities in Southern California say a 51-year-old woman has been arrested on child-endangerment charges after her 2-year-old granddaughter drank tea with methamphetamine in it.

Riverside County sheriff’s Sgt. Craig McDonald says the toddler’s mother called authorities Monday morning saying the child had not slept and was talking rapidly, scratching, and couldn’t sit still.

The girl was taken to a hospital, where it was determined she had meth in her system.

McDonald says investigators found that the grandmother, Cynthia Watson, made a cup of tea the night before and put meth in it “to get herself high.” The girl apparently drank it when the cup was unattended.

Watson, who was visiting from Oregon, was held on $35,000 bail. She’s expected in court Wednesday. It wasn’t immediately known if she has a lawyer.

The toddler is expected to make a full recovery.
