I tried to search in the bupe mega thread and was having problems trying to find an exact answer to this question. I have read on here that IV'ing bupe will make its effects a little shorter but I was wondering if snorting it will decrease the amount of time required to feel opiates again? Reason i am asking is because last night feb 8th i snorted 4mg of subutex (bupe) at 11pm and i had snorted a 8mg subutex at about 2pm the same day. I have an opana 40mg burnin a whole n my pocket as i type this and i was planning on snorting this opana about 40 hrs after my last bupe dose which would be about 3pm tomorrow (feb 10th). prior to feb 8th when i snorted 16mg of bupe by the end of the day, i had only taken like 2 mg of subutex the entire day before (feb 7th). I weigh 130 pounds im 6'0 tall very very high metabolism and normally a 40mg opana would get me nodding my ass off. So i guess what i am asking is will this 40mg of opana snorted 40 hrs after an insulffated bupe dose of 8mg get me high? or should i wait till a full 48 hrs or even longer? any input is greatly appreciated.
