Yeah I agree if you've properly filtered there should NOT be enough particles in the syrimge to clog it. I think it's in anyones best interest to have very clear shots... Sometimes I'll let one a bit foggy pass, but not if I can actually see any particles. If that happens you should really shoot the mixture into a clean spoon and refilter/redraw. Yes, it's a pain, but a clear shot is a guilt-free shot
Remember, those particles are going to get clogged up in your heart, best to take the time to keep them to a minimum. If you have to shake the syringe like a snow globe to keep it from getting clogged then you do NOT have a properly filtered shot.
Anyway, I take a lot of care to properly prepare shots, so I felt the risk of bacteria growing in a "pre-made" shot was low enough to risk it.
I ended up compromising and making an extra batch at night in my bedroom, so I used my pre-mades within 24 hours, not 48. I felt reasonably safe with that.
I know we're all better safe than sorry, but really, can anyone tell me that a well-prepared (i.e. clean) shot of dilaudid that has sat in a fridge for 24 hours actually poses a risk worth worrying about?
I know the chances of bacteria leading to infection or cotton fever aren't zero, but I think all of us are sometimes in positions where we have to deal with risk - its just a matter of educating ourselves to minimize the risk to the point where it's minimal.
