With no opiate
tolerance half of a 10mg is too much. Start with snorting
a 1/4, you can always do more but not less. You won't have to worry about the asthma like symptoms these Roxane oxymorphone
can cause with just a single use. Unless of course you already have asthma.
2.5mg of oxymorphone snorted = 20mg of oral oxycodone
