No clue what will happen tbh, but if i were you i would just pop them in my mouth and flush em down with some soda, read somewhere that the soda helps it get into you faster, this only maybe true for syrup but not sure :/
I dont see why people feel the need to snort everything, that shit really is bad for your nose. Ohh, and Codeine is converted to morphine by the liver after ingestion. Snorting won't work. Have fun with a fucked up nose tommorow.
