Can you sniff the reformulated Oxycontin?

You can, but don't expect a whole lot to happen. First of all, percocets are a mix of oxycodone and acetaminophen. Snorting acetaminophen will block the mucous membranes of your nose, preventing most of the oxycodone from getting through. Second of all, even if you filter out the acetaminophen (a tedious process), oxycodone's bioavailability when snorted is half of when it's taken orally, meaning you have to snort almost double of what you would eat orally to feel the same.
