I'm not in Colorado but I saw one of the downsides the other day which is the manufacture of items like candy bars with multiple serving sizes of THC in the one bar. People aren't paying much attention to the serving sizes and there appears to be no restrictions in place yet on how much can be in a given food item. I'm in favor of legalization but there may need to be some more restrictions in place on how much THC could be included in any one item.
