I was talking about it as well. I have experience with both and do not find hm stimulating at all.I was talking about the IV rush that lasts about 30 seconds not the high.
However you describe it, there's a consensus on this forum that IV hydromorphone has a type of rush other opioids dont. Plenty of threads over the Yeats on "which opioid has the best IV rush" and the consensus is always the same usually hydromorohone or oxymorphone
I don't care what the majority feels. I've found people lie about drug use so I don't believe everything I read here.
