I agree with the above --- don't snort the percocet, you're literally wasting some of the drug because it's a lot of powder, and there's no way of knowing if that measly few mgs of goodness is such a large pill will even get absorbed. APAP is very bad for your liver, so looking into a CWE when using small dose pills with that much APAP (this needing to take several of them) is a good idea, it's really easy too. If not, I'd say if you're feeling nauseous, don't eat the last one. The few mgs you blew didn't get absorbed the way what you swallowed did...save it for another time. I hate puking, even when it's from opiates.
