I know that anecdotes <> evidence, but last week while in line for Hive there was a group of 5 people behind us in EP line.  2 couldn't stand and kept falling over, frequently into us.  My wife and I both said something out loud to them, sometimes within earshot of a TM.  They were laughing about how much pregaming they'd done with everclear.  Now mind this is still early in the night, like around 7ish.  At one point, I ducked out of line to "tie my shoes" and let them get a few people ahead of us so they wouldn't ruin our run through the house. 
TBF, I think they were removed at the end of the house.  I didn't see if they had done anything while in the house (fallen over, touched something, etc.) but at the end, a TM kinda stepped in front of a few people in front of us and pulled the black curtain aside as if to hide something, and I didn't see them on the long walk back to the house entrance.
