Colorado health authorities suggested banning many forms of edible marijuana, including brownies and cookies, then dropped the suggestion after it went public Monday, The Associated Press reported. The Colorado Department of Public Health and Environmentโs proposal sparked marijuana industry outrage and legal concerns from a regulatory workgroup that met Monday to review the agency's suggestion. "If the horse wasn't already out of the barn, I think that would be a nice proposal for us to put on the table," said the department's deputy executive director.
