Gov. John Hickenlooper also signed a bill Wednesday to eventually set limits on marijuana possession in its concentrated form, which yields far more servings than identical amounts in its plant form.
The bills were signed at the Children's Hospital in Aurora, where doctors say they've seen an increase in accidental ingestions of marijuana products. Last year, there were a total of eight children treated for eating marijuana, compared to nine children so far this year, said Dr. Michael DiStefano, medical director of the emergency department at the hospital.
The new law on edibles calls for the Colorado Department of Revenue to convene a group of stakeholders by Aug. 1 to look at what rules should be in place to make marijuana edibles clearly identifiable, as well as possible changes to dosing amounts. Rules are due by Jan. 1, 2016.
