A new Colorado law on medical marijuana use at public schools is getting a second look in the legislature because no school districts are allowing it, even though the law says they can.  

The bill, up for its first vote in a state house committee Monday, would make Colorado the second state to require public school nurses or caregivers to administer cannabis-based oils or allow students to wear cannabis patches.   

The law does not allow the use of smoked marijuana on a school campus.

While the state Department of Education is neutral, some school officials oppose the marijuana requirement, saying it could endanger federal school funding.
