Three 3rd graders at Sonora Elementary School in Tuolumne County were caught last week smoking marijuana in a bathroom.
The students were discovered by another student, who reported the incident to administrators.
Sonora Police Chief Mark Stinson said the the two 8-year-olds and 9-year-old are too young to face criminal charges. He said on Wednesday police were looking into whether someone supplied the drug to the kids. Stinson also said it's possible parents could be charged with contributing to the delinquency of a minor, if they're considered responsible or careless.
Among those most surprised about the incident is drug prevention teacher Sarah Sommarstrom, who usually deals with 7th and 8th graders.
"I don't even know how to begin talking with 3rd graders about the use of drugs and alcohol," Sommarstrom said.
School officials declined to offer any information on what happens next with the children, calling it a "disciplinary issue."
Sommarstrom couldn't help but point the finger at the parents of the children.
"Have to think the parents. Where are the parents in their lives, are the kids going home alone after school and for how long, and are the parents using?" she asked.
Stinson said they were the youngest pot smokers he had encountered in his 33 years in law enforcement.
