 GREELEY, Colo. (CBS4) – A school in Greeley is asking parents to be more vigilant after a 10-year-old boy admitted to selling marijuana to other students on the playground and another student came to school with a marijuana edible candy bar. 
  
 Both incidents happened in one week. 
  
 School officials are now asking parents to pay attention to where they are keeping their recreational marijuana after the fourth graders brought the items to Monfort Elementary School in Greeley. 
  
 John Gates, director of safety for Weld County School District 6, said there were four students involved — three boys and a girl. The students were all 10. 
  
 Gates said the students faced tough discipline but not suspension or expulsion but would not provide specific details on their punishment. 
  
 One boy admitted to taking a small bite of the candy bar but he didn’t get sick, and a medical exam showed he didn’t suffer any harmful side effects. 
  
 Gates said the boys told them they got the pot from home. That marijuana appears to have been legally purchased by adults. The grandparents in two families apparently made the purchases. No charges are expected to be filed. 
  
 On Monday a student who was not involved told school officials about the pot selling on the playground and the next day a student tried to trade an edible for some of the student’s marijuana. 
  
 “It was the simple fact that we had adults that didn’t secure their marijuana,” Gates said of the grandparents, urging adults to take care with the drug. “That sure is concerning because this would have never happened had the marijuana not been so accessible to two 10-year-old boys.” 
  
 Monfort Elementary School principal Jennifer Sheldon sent home a letter to parents on Tuesday stating that even though it’s easier for adults to get marijuana, children potentially have greater access. 
  
 A portion of that letter reads: “We urge all parents, grandparents and anyone who cares for children to treat marijuana as you would prescription drugs, alcohol or even firearms. This drug is potentially lethal to children, and should always be kept under lock and key, away from young people.”

 DENVER - 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. 
  
 "Both of these kids took the marijuana without the consent of their grandparents," said Gates. 
  
 Gates said the four students involved will be suspended for a "significant" number of days, but declined to say exactly how long the punishment would be. Initially police were called, but officials have determined the incident will not he handled as a criminal matter, he said. 
  
 "We hope to send a good message here without ruining anybody's lives. The message we really want to get out here to the adults is, 'for crying out loud, secure it,'" Gates said. 
  
 Adults 21 and older have been able to buy recreational marijuana legally in Colorado since Jan. 1. 
  
 In a letter sent home to parents, Monfort Elementary School Principal Jennifer Sheldon said no student was injured. 
  
 "We know that many adults have greater access to marijuana since the change in the drug's legal status in Colorado," Sheldon wrote. "We urge all parents, grandparents and anyone who cares for children to treat marijuana as you would prescription drugs, alcohol or even firearms. This drug is potentially lethal to children, and should always be kept under lock and key, away from young people." 
  
 The side effects of edible marijuana - which can be far more potent than smoking a joint - have been raising new concerns after two recent deaths in Colorado. In one, a 19-year old college student died when he jumped off a hotel balcony after eating a marijuana-laced cookie. In the second, Richard Kirk, 47, was charged with shooting and killing his wife while she called 9-1-1, telling police her husband had consumed pot-infused candy. 
  
 Colorado's legislature is currently considering new safety regulations for marijuana edibles, including bills requiring stronger warning labels and lowering the amount of THC permitted in food.

A pair of enterprising fourth-graders in Colorado got caught dealing marijuana pilfered from home at their elementary school, reports ABC News. Officials at the school in Greeley originally got police involved, but they've decided to handle it internally with suspensions and with a message to grown-ups: "For crying out loud, secure it," asks the school district's security chief. Authorities say one boy stole (legally bought) marijuana from his grandparents and sold it to three young buyers at his school, netting himself $11 in the process. The next day, one of those buyers brought in a marijuana candy bar and tried to swap it for some of the leafy stuff, reports CBS Local. "It was the simple fact that we had adults that didn’t secure their marijuana," says the school official. "That sure is concerning because this would have never happened had the marijuana not been so accessible to two 10-year-old boys." The two other buyers, also 10, face suspensions, too.
