Marijuana: Could city council ban smoking near schools even on private property?

In addition to voting on a proposed plastic bag-fee bill at a meeting tonight, members of Denver City Council will also take on an amendment that would allow people to smoke marijuana on their front porches, thereby formalizing an unlikely reversal of a rule that would have banned it. One key councilwoman doesn't expect another flip-flop this evening, but she points to other new proposals on the agenda, including one that could make smoking near schools illegal even on private property. And that's not all.
