  – Two Colorado fourth graders were busted for selling marijuana at their elementary school, prompting officials today to urge adults to keep their weed locked away from kids. School officials said a 10-year-old fourth grade boy brought a small quantity of leafy marijuana to Monfort Elementary School in Greeley, Colorado, on Monday. “He sold it to three other fourth graders on the school playground, which resulted in a profit to the young man of $11,” John Gates, director of safety and security for the Greeley-Evans School District, told ABC News. The next day, Gates said one of the three young buyers brought a marijuana edible to school and gave it to the boy who sold the pot on Monday. That boy took a bite, but did not suffer any ill effects, Gates said. Both boys apparently got the weed from relatives, according to Gates. More
