Lawmakers held off on a directive to implement new restrictions on marijuana edibles in Colorado, but will study the issue to consider legislation next year. Legislators are also advancing a measure to limit pot in its concentrated form. A Senate committee unanimously approved a bill yesterday calling for a study on what rules there should be on how edibles look to prevent accidental ingestions. The bill was amended from its original form, which would’ve directed state regulators to broaden a ban on certain types of edibles to include products that mimic other foods or candies. The study is supposed to yield recommendations in November. Another bill advanced by the committee seeks possession limits on concentrated forms of marijuana such as hash oil. Both bills still face full votes in the Senate.
