I don't think it was so much Ruby inhaling it, as it was her sneezing on it. It seems like powdered Dust is more volatile than Dust crystals.

In order to set off a crystal without directly using it, you have to shoot it, as demonstrated by Torchwick in the series premiere and Ruby in Round One.

Powdered Dust, meanwhile, can easily be set off by disturbing it once it's in the open air, either by sneezing on it (like Ruby) or coating a blade in it and then swinging that blade (like Weiss seems to do with Myrtenaster). Weiss also uses her glyphs to direct powdered Dust, but I'm not sure if her glyphs agitate the Dust or if her glyphs allow her to activate it through Aura (considering WoR: Dust said that Dust can be activated by Aura).
