Local police say the Driver Elementary student showed the pot to his teacher and explained that he stole it from his dad's truck to help him kick the habit.
The kid's mother was called to the school and heard the explanation as well.
The student has been suspended pending his expulsion hearing, which has been set for next Friday. Extenuating circumstances will be considered, according to a school spokesperson.
"Policy is policy, but I do think they need to check into the situation more," former teacher Jonathan Lewis told NewsChannel 3. "I mean who knows what the child's homelife is like and what kind of exposure they're getting besides drugs."
