Schools and drug experts are warning parents to beware of "digital drugs" that Mustang High School students blamed for their apparent intoxication.

Three students were sent to the principal's office when they appeared to be high on drugs or alcohol in March, said Mustang School District Superintendent Bonnie Lightfoot. She said the kids explained that they had tried something called "i-dosers."

Young people plug into i-dosers through putting on headphones and downloading music and tones that create a supposed drug-like euphoria.

The technology is designed to combine a tone in each ear to create a binaural beat designed to alter brainwaves. Whether it was kids faking it, the power of suggestion or a high wasn't clear to administrators who investigated the students' claims. Adding to the mystery was the fact that these kids weren't troublemakers. So the worried Lightfoot sent parents a letter warning them to be aware of this new temptation to kids.
