Gov. John Hickenlooper also signed a bill Wednesday to eventually limit marijuana in its concentrated form. The bills were signed at the Children's Hospital in Aurora, where doctors say they've treated nine children this year who accidentally ate marijuana edibles. Last year, there were a total of eight cases.

The new law on edibles calls for state regulators to look at what rules should be in place to make marijuana edibles clearly identifiable and possible changes to dosing. Rules are due by January 2016.

The other law is aimed at setting possession limits for concentrated marijuana, which yields far more servings than in its plant form.
