A 3-year-old North Florida preschooler brought a very special show-and-tell item to school Monday: a couple bags of marijuana.

The Lake City toddler was found with two baggies containing less than 20 grams worth of pot, according to firstcoastnews.com.

When the youngster showed it to another student, the student told a teacher who tipped off Columbia County Sheriff's deputies.

When deputies searched the preschooler's home, no drugs were found. The boy's mother said she had no idea where the pot came from, but the boy is developmentally disabled and rides a bus everyday.

The Department of Children and Families has opened an investigation, but there have been no arrests so far.
