Colorado schools would be required to allow medical marijuana use under a bill nearing its final vote in the state Legislature.

The bill won unanimous approval Monday in the state Senate. It expands a 2015 law to allow schools to permit non-smokeable marijuana medicines at school, as long as the school districts agree and the drug is administered by a parent or adult caregiver.

No school district has agreed to allow pot, however. This year's bill makes it a requirement.

The bill has already passed the House. One more formal Senate vote is required before the measure heads to the governor's desk.

Colorado would be the second state after New Jersey to require schools to accommodate medical pot.
