So, when actors make like they're snorting up lines of cocaine, do they actually inhale whatever powder is standing in for the coke? That really can't be good for their brains and internal chemistry, even if it's something like Sweet 'n' Low or flour or whatever. And it really looks like they're snorting up whatever that powder is, so either they're doing a hell of a job with the special effects, or they're actually inhaling it.
