I am going to pop in and agree with 99% of what infantannihilator said, sans one bit which I will describe. First off NO.... do not attempt to use any sort of filter with an insulin syringe. This doesn't mean "oh ok well then fuck filtering"... no no no. If this is all of the equipment that you have access to, then DO NOT attempt any form of injection. If you would like to make the oral route more pleasurable then do as follows on an empty stomach: Crush the Dilauded into a fine powder --> mix that powder into a small amount (20mL?) of water --> drink the liquid --> drink some grapefruit juice (although efficacy of this is not well established, it can't hurt) --> wait and enjoy. In my opinion, this is your ONLY OPTION right now. In order to show you just how far off you are from proper injection technique, I will outline it below.
Injecting Water-Soluble Tablets
1. Hydromorphone (Dilaudid) does in fact qualify for this.
2. Using a small beaker that has been sterilized (either by autoclave or 15 minute immersion in 95%+ Ethanol -- Everclear), allow to fully dry, insert powdered tablet material.
3. Using a brand new syringe (insulin is fine), draw up the appropriate amount of Bacteriostatic Injection Solution (BIS, this contains 0.9% Benzyl Alcohol and no bacteria) and place into the beaker. To determine the proper amount use this as a guide.... 1 mL per 8mg. That means that one 8mg Dilauded should be dissolved into 1mL of BIS (if using insulin syringes which are 1/2mL).
4. You now have a cloudy solution that not yet safe to inject. It must still be filtered.
5. You must now use a completely new syringe(not insulin) to draw up your solution out of the beaker. This must then be attached to a 0.2 sized wheel filter and pushed through into yet another sterile beaker.
6. In the new beaker you now have a sterile solution containing 8mg of hydromorphone within 1mL if Bacteriostatic Injection Solution. (It should be crystal clear, if not, you did it wrong.)
7. From this beaker you should now us yet another sterile syringe large enough to suck up all of the solution. Transfer it into a sterile injection solution holding unit. These come in various sizes and will have the small circular rubber spot for inserting sterile syringes. (Fun Fact: nothing except for a brand new, sterile syringe should ever penetrate that little grey rubber spot)
8. Now.... Using a brand new never used insulin syringe, puncture the small grey rubber circle on the container holding your hydromorphone solution. Suck up 45 units into your insulin syringe, leaving 5 units to pull back and insure vein penetration. (Not necessary if subcutaneous)
Note: The "recipe" can be scaled. So you can put 16mg into 2mL etc.... Hydromorphone is actually quite soluble in water, so the number of milligrams per milliliter may be increased. I DO NOT CONDONE DOING ANY OF THIS, but I believe that harm reduction is more important.
*** IF YOU CANNOT DO WHAT IS DESCRIBED ABOVE THEN DO NOT INJECT. PERIOD.*** I cannot stress this enough, it is literally life or death. There are so many infections crawling around today, many of which are highly resistant and prone to causing septicemia, which is a horrible way to die and is quite often seen in IV drug users who have ignored sterile technique. There are plenty of online vendors who will sell you exactly what you need, cheaply. There are no excuses. (and no... the FBI will not break down your door for ordering the proper supplies.)
Oh yeah, as promised, my minor point of dissent with infantannihilator is that Subcutaneous Injection is a perfectly viable route of administration. It lasts longer than IV, presents fewer complications, and is in general a lot harder to screw up. In fact, there is a lot of current research suggesting SC Dilaudid post-op instead of using mepiridine or dilaudid drips. Of course, all of this is highly contingent on sterile technique.
