LOL I sometimes like to put ½ a tspn or less in my coffee when I’m making a fresh pot, I have noticed if you put more it won’t drain too well through the filter, it’s obvious it is a very fine powder so putting that in your mouth and accidentally inhaling at the same time would probably have the same feeling of inhaling large amounts of particles in the air, you cough a lot, and when something goes down the wrong pipe..well it feels like your choking. But unless you inhale enough to stop your airway, uh yeah you won’t die, but you’ll cough enough to feel breathless like your going to.
