A Jacksonville, Arkansas, toddler is among the youngsters affected by the recalled toy Aqua Dots--which has ben found to contain a chemical that turns into a powerful "date rape" drug when eaten. Twenty-month-old Jack Esses is home from the hospital. But while he was at Arkansas Children's Hospital, his mother says the boy was slipping in and out of consciousness and she was afraid her son would die.

The boy had played with Aqua Dots, which had been given to his sister.

Jack's mother Shelby Esses, who lives with her husband Jonathan and their three children at Little Rock Air Force Base in Jacksonville. She says her son started stumbling and throwing up Aqua Dots after playing with his sister the day before Halloween.

Esses says she believed the Aqua Dots had something to do with the illness.

Jack started losing consciousness on the way to the hospital October 30th, and would gain consciousness to vomit. Dr. Matt Jaeger of Arkansas Children's Hospital treated Jacob and said he was very worried when he saw him. The hospital started tests and did a head scan. But within hours, the crisis was over.

Jaeger says the boy recovered so quickly, Jack could be discharged.

Jaeger said Shelby Esses did the investigative work that led to the cause of her son's illness. She tracked down the components of the toy and provided them to the hospital lab, which later identified the chemical. Shelby Esses got the news in a hospital e-mail Wednesday, the same day Aqua Dots were recalled.

Scientists say a chemical coating on the beads, when ingested, metabolizes into the so-called date rape drug gamma hydroxy butyrate. When eaten, the compound--made from common and easily available ingredients--can induce unconsciousness, seizures, drowsiness, coma and death.

Retailer Toys "R" Us Inc. said it issued a "stop sale" on Aqua Dots product line on Tuesday in its North American stores and on its Web site after it learned of the news.
