I saw Vanessa Hudgens on Leno a few nights back & she said in the scene, they were snorting B vitamins & running around the set, so yes there is def some snorting going on in the movie.
So I saw this last night, had to go in bross faded. It was... something lol. His take on the MTV generation. Franco is full of shit saying he wasn't portraying RiFF RAFF, his mannerisms & way of speaking was on point. Probably would have been better if it was Reezy tbh. Didn't really like the ending & it's pretty short but it was worth seeing.
