GREELEY, Colo. -

After fourth graders were caught dealing pot at their northern Colorado school, the principal sent home notes asking parents to take care with the marijuana that adults have been able to buy legally in the state since January.

In the letter sent home Tuesday that KDVR posted on its Web site, Jennifer Sheldon of Greeley's Monfort elementary cautioned that because it's easier for adults to get marijuana, children potentially have greater access. She says the drug should be kept locked away.
    
Theresa Myers of Weld County School District 6 says a 4th grader sold loose leaf marijuana to several students Monday. The next day, another offered to trade an edible marijuana item for some of the loose leaf pot.  The district says disciplinary action has been taken.
