I haven't finished watching the video yet but apparently they use this "smoke shack" out at Breckenridge as part of the story. I saw a post on Facebook that following this report this shack was destroyed, but I can't confirm that.

We placed hidden cameras inside and discovered people streaming in and out all day, almost every one of them for one reason only: to get high.
Our cameras captured one skier take puff after puff after puff. An Inside Edition producer caught up with him before he took off down the mountain, “You were smoking nonstop up there. Are you safe to ski down the mountain?”
“Absolutely,” said the skier. “I'm 100% safe to ski.”
