A fourth grader was arrested after selling marijuana to three schoolmates at a Colorado elementary school.

According to an Associated Press story, the boy, a 10-year-old student at Monfort Elementary School in Greeley, Colorado, was busted for selling a small amount of edible marijuana to three other fourth graders.

“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.

Gates told the AP Wednesday that the students involved, three 10-year-old boys and a 10-year-old girl, faced tough discipline but not suspension or expulsion. One of the children tried a small amount of the edible marijuana.

According to the story, the marijuana the boy sold was legally purchased by his grandparents. As of Jan. 1, adults 21 and older have been able to buy recreational marijuana legally in Colorado.
