Well my friend, I've been using both formulations of the drug for years, mainly subutex nowadays though. I find quite the contrary, however I have lately noticed that if the intravenous dose of suboxone is kept to less than 1.5mgs, I do get some sort of 'high' from it. After that the naloxone ratio is too high for me to enjoy it. However, I would NOT recommend injecting suboxone ever, it's gross and dangerous. Subutex is better but should still be micron filtered, as everyone on this forum will now tell you. Also, everyone is going to tell you that there is no difference whatsoever in the effects of the two formulations, no matter what r.o.a. is used. The reason for this, you can find if do a little research but simply put, naloxone is only in those pills for political reasons. Even addicted users can bang up a stop sign without getting thrown into w/ds if they don't take it with other opiates in their systems.
So basically, when I shoot tex I get a great opiate type high from it. I do this several times a day. However, when I shoot suboxone, personally, I do not get much out of it. I usually take them some other way because it's not worth it to me. My theory is naloxone temporarily competing with buprenorphine at receptor sites, but again that's just my personal theory.
