Lots of good info here - just wanted to add that I do believe Dilaudid has talc indirectly -- it contains magnesium stearate, that when mixed with water will form talc carbonates.
I believe you are actually correct with this and it's one of the reasons why I consistently use .20um micron filters when shooting Dilaudid's. Not to mention the sheer number I get a month would be foolish not to try and do it the healthiest way possible. I mean I don't IV all 6X 4mg's a day but lately my pain level has been horrid and I've definitely IV'd a lot more then i'm used to IV'ing so i've stocked up on .20uma nd .45um micron filters for health reasons.
Plus I have a consistent source for them even in small quantities and they are VERY affordable. (#5) .20um micron filters will only run $10 plus a smalls hipping fee and you'll have them in 2 days from the reliable source I use. As the moderator Captain Heroin had said to the OP. Or even ANYONE else. Simply PM me and i'll get you into contact with a personal contact of mine who deals with shipping these micron filters everyday and will get you everything you need. For less than $20 I can have (#5) micron fitlers in any size you want, with (#5) luer lock syringes that fit them, & shipping to your house in 2 days with your payment guaranteed with insurance through PayPal.
I make nothing off of this and my contact makes a very small amount, we both do it for the sake of harm reduction and the community. We both believe in educating people and making unhealthy practices, like IV'ing pills. As healthy as possible. Nothings worse then doing a bunch of un-changeable damage to your body that doesn't even show up or cause problems till long after you've ceased the dangerous practice. Problems from IV'ing pills without proper filtration are scary because they can show up LONG after you've quit doing them. Talc in your lungs can sit there for years. Anyone looking for micron filters though, PM me and I can give you an e-mail address for a very compassionate legit fellow who can take care of you even if you only have $10 for them. I know 95% of the sites you can buy them from online simply don;t have any quantity that costs less then $75-$100 which someone who is only going to do this once in awhile probably doesn't want to spend. I know I didn't.

As far as Dilaudid though, it is one of the much safer pills you can IV even if you only have cotton filters laying around. Much Much safer than OC's. Shooting an OC with just cotton filters is a sure fire way to get all kinds of other ingredients floating around in your circulatory system that don't need to be there & aren't going to dissolve or filter out on it's own. If you MUST use just cotton the best thing you can do is filter 3 times and do it this way. Filter once regular in the spoon just like you would anything (ex: heroin) then take an extra syringe and pull the plunger out. Pack this syringe about half an inch full of cotton from qtips. I mean pack them in there good and hard. Now take the syringe full of liquid you drew up already and back load it into the syringe you packed full of cotton. Put the plunger back in now and force the liquid to be pushed through the packed cotton you put in the syringe.
There should be some resistance and you should be having to give it a decent amount of pressure to push the liquid through the cotton you packed in the syringe. This collects a lot of the crap you don't get from just drawing through a cotton. As your pushing this liquid through the syringe packed full of cotton be collecting the liquid coming out into a total clean new spoon. Now drop a cotton into this liquid and draw it up into the syringe your going to shoot with. Now this liquids been drawn through a cotton, pushed through a syringe packed HARD full of cotton, and then drawn through a cotton again. This form of triple filtering i've found to give the closest to a crystal clear solution i've ever been able to get without using a micron filter. This is my ghetto triple filter method that i;ve found to be good for Dilaudid if you don;t have a micron filter. It leaves clear liquid not cloudy at all.

All in all just be safe IV'ing pills. A lot can go wrong, a lot of health problems can rise from it later, & do yourself a favor if it's your DOC or something you do a lot. Get some micron filters. PM me and i'll set you up with someone. Whats $10 and 2 days waiting if it saves your lung, your arm, your heart, etc. I'm not preaching at all, and i'm not making a dime off of this. I'm just trying to help my bluelight brethren out.
Also to the OP. NO MORE DILAUDID COLDSHAKES. Please

If you have any questions you can always PM them to me. I'm not only an addict, and not only a chronic pain patient. I'm also an RN and I like to help people. It's my job. Most ER RN's wouldn't give you IV advice or help you locate filters, but im not like most. I'd rather educate people on how to avoid medical issues then have to lecture them about it later on why it was dumb. Im all about prevention.
I love bluelight and will do anything I can to give back to it for everything it's given me over the last 6+ years of my life.
