I wonder if they do that just so it's easier to see what's going on. Lotta dumb people watch TV and they need things spelled out for them. (though if you think about it, you could mime shooting up with a stick and most people would get what you're trying to convey)

Worse was before they went to Livia's wake, Furio, Chris and Ade are snorting blow and hitting a bong.....clearly no one in that room had used a bong before. Ha.
