ELI5: What's happening when actors in movies and TV shows are snorting lines of cocaine?

It looks like they're legitimately snorting something, obviously it's not real drugs, but is snorting anything safe? Are they actually snorting anything at all? Is snorting even the word we use anymore?

Its typically lactose powder, or vitamin b powder for those who are lactose intolerant. These powders are harmless even if snorted. If they are snorting a lot of "coke" the straw is typically coated on the inside with vaseline, which will cause most of the powder to stick to the straw, instead of going into the actors nose.
