OK, back on-topic..... The OP asked about and got answers for the basic question; will pot smoking be allowed in CO state & national parks / campgrounds / RV parks. The answer really has not changed before or after the change in laws in CO ... Pot smoking (and open alcohol consumption) is not allowed. You cannot consume in public. I think most users and non-users would agree that this is for the benefit of the public in general. We don't need to see people walking around drinking or smoking/vaporizing weed, especially when packed in to a contained environment like many campgrounds tend to be.
Now, I will tell you that if you have spent any time at all in campgrounds, both in CO and all other states, you have been camping next to people that consumed pot ... probably without you even noticing. Sure, some of you have/will smell the odor of people burning the weed... but in most circumstances, you have not and will not detect your fellow campers that choose to consume. Especially with the increased use of vaporizers.
My personal beliefs aside, public consumption has not been and will continue to not be a problem. Especially in most campgrounds. As far as the actions of fellow campers that are stoned, drunk, both, neither...most of the behavioral issues will come from alcohol. Yes many people will consume both alcohol and pot at the same time, which does pose some issues, but the real problem is with the drunks. They are the overly loud ones. The ones that are baked just sit around the firepit staring into the fire. They will also be the first to jump up and help you if you need help... IMHO
