First responders treated five students at Goodyear school on Tuesday after the kids had eaten edible marijuana.
Goodyear fire said the children, between the ages of 10 and 11 years old, attend Incito Schools, located near Sarival Avenue and Van Buren Street.
All of the children were treated and evaluated by firefighters before being released to their parents.
No one was transported to the hospital.
Goodyear fire officials on Wednesday said one of the children brought the edibles to school and gave it to four others. Police say the candy came from the house of one of the children, and police believe it was leftover Halloween candy that was laced with THC.
Police say it's impossible to trace where the candy came from, because the candy was collected from trick-or-treating by several kids and all put into the same bowl.
Police say this is a good reminder for parents to inspect candy carefully before letting children eat it. So far no arrests have been made in the case.
