No SWIM here. Just say its you. I'm not a moderator or anything, just thought I would let you know, seeing as it is your first post, and you probably had no idea, it even mattered.. Anyways, to answer your question.. Just don't... It will not lead anywhere good, minus the rush you get.. I have mixed just about every IVable opioid/opiate, including hydromorph with coke and speedballed, many different times and many different ways both smoking and shooting shit.. crack and coke powder... H, oxy, opana, HM, and morphine.. have mixed them all together at different times one time or another... and yeah, HM+coke is one of the best IV rushes I have ever experienced. IT is extremely dangerous though, as keeping pointed out above, and I wouldn't get started with this as you will like it, and you will want to do it again.. more than likely! If you enjoy hydromorph on its own and cocaine on its own, not sure if you IV or not? But if not, definitely do not start.. Speedballing snuck up on me, and became the most hellish addiction (besides benzo addiction, and running out in benzo WD. that's the worst.. and I have heard 'done is too..)I ever really had to get past. Well I'm on subs now, have been for years.. and I feel a lot better, consistently.. I was so over having to go find both blow and opis every single day, and spending ever last penny on it, every single day.. when I made 100s of dollars in tips everyday serving at a resturaunt. NOT WORTH IT! IF you must, be extremely careful.. don't say no one warned you about how dangerous and addicting this is though! It is a sick rush, I cannot deny that.. but that's all.. after that rush, that lasts maybe 3-5mins if your lucky.. its all down hill, and the high fades fast... then you want more and more, and will proabably feel like doing whatever it is you need to just to get more HM and blow... trust me, not a nice addiction.
