There's some people who with the right filters (SteriFilts, which were invented to shoot pills, which comes with injection kits at exchanges) does the trick for all kinds of morphine Kadians, Avinzas, M-Eslons which are beads in a gelcap, can be put in a mortar and pestle and you crush those beads and they turn into a cocaine-like powder) who know how to enjoy morphine IV. MS IR's have to be filtered extremely well, they have a lot of shit in them. If you are from the polite (goddamn any of you who keep saying this, we're just normal people, unlike a lot of places in the US lol) north, Statex named Morphine IR's are just like Dilaudid (brand name) with only 2 harmless easy to filter away fillers. I don't know if Statex is available anywhere else, but they got 25mg IR and 50mg IR. The 50mg IR Statex would change your opinion of morphine if IV'd.
If you want to get high with those which are beads in a gelcap without shooting up, just crush the powder put in a drink, or scraped back into the empty gelcap. Surely 200mg of IR morphine will hit you like a brick even orally, it's very different when eating large IR doses as compared to an equivalent XR dose. Also, some generic ms-contin like pills actually don't gel like the brand-name. But yeah, saline will do the trick.
I know when I had just a medium tolerance, eating a 200mg generic ms-contin red rectangles of awesomeness, they would be amazing as a background opiate while I was eating a little oxycodone IR (20mg). Any more and I would have played with fire, then.
Also, never snort morphine, it's got even less bioavailability that way than orally. I think they were shooting you with 15-20mg of morphine, I don't know why you were there, which is the standard dose if someone is at the hospital for a few days needing IV morphine/hydromorph/demerol/pentazocine (the last 2, they use mostly with people allergic to morphine, although I find 200mg of Demerol IV'd is heavenly, same with Pentazocine (Talwin). If from the US and you ever, in the unlikely, find yourself some Talwin pills, do not shoot up, the american Talwins have naloxone in them, because of how much better it is IV'd than eating the 50mg pill or 2. Morphine in the correct dose for you, which you seemingly never had is better than hydromorphone (which is opi-crack that led me to the ORT-wagon), because it works 4-6 hours of solid nodding. Hydromorphone is all rush (which is amazing, out of this world, amongst the best thing in the world, I wish we Oxymorphone marketed here, we only can have them through a compounding pharmacy, and they're going to make you Opana XR/SR/XL whatever the long duration ones are, but if I could get my hands on just a single 10mg IR oxymorphone, I'm sure I would love it, rush is apparently like hydromorph and stronger than heroin when IV'd and lasts 4 hours at least too. With hydromorph, it's rush, then 20-30 minutes of feeling okay, then you fiend for another hit. Making larger hits does not change anything, the most hydromorph I shot at once was 14mg and it didn't have a better rush than 8mg and didn't last longer than 20 minutes also.
That's why I wish our goddamn HydromorphContins 30mg (highest dosage) would not be so expensive, insurance or street, because, when I was a chipper and the guy didn't have oxy in any form, I took some of whatever he had, and then there was no SteriFilts, only microns and they cost a lot (bulk buying obligation most of the time, Sterifilt is marginally not as good), so I just ate 2x30mg HM Contins.
Holy shit is continuous hydromorphone amazing, they're 12 hour deals, and, yeah, I laugh at the 3mg, 4.5mg, 6mg, 9mg, and even the 12mg (unless one has many), anything under 12mg and people expect you to feel some pain relief only even from a 6mg hydromorphcontin is out of their minds). I never saw those lower than 6mg but those dosages must be reserved for kids with cancer. Anyway, you tell the average canadian junky that you ATE a hydromorphcontin, you committed sacrilege, that's like 6.5 rushes in there! (in a 30mg one, same principle as the Kadians, m-eslons etc.) This female cousin of mine who lives way south in Ontario since 5-6 years, has obtained 10mg Opanas IR, likely brought in to Windsor from Detroit, she's got fibromyalgia with a script for methadone pills for pain (2x10mg a day) but sometimes that's not enough. She said she wished she had dilaudid because she wanted to put in IR morphine powder with hydromorph and oxymorph in the same rig. She did it with 150mg morphine and 2 opana IR's and said it was like being "reborn", where tolerance withdrawal didn't exist anymore.
That's why I find doctors, like my GP, who believe and put to practice opiate rotation is doing the smart thing. Said cousin before methadone was switching from 4 different kind of opiates depending on the month, oxycontin 40's, Dilaudid 8mg, Demerol 50mg and Kadian 130mg, rotating and she never shot up then. She has problems doing it to herself these days so much her rheumatoid arthritis + arthrosis in multiple joints of the body + the fibromyalgia. But she got tired of it, she wanted something that worked all day and not have to think about it, she's also got to take cholesterol pills, Lyrica, amytriptyline, nortryptiline, 81mg aspirin, you get the picture.
If I ever really got the urge just grabbed my cash and scored the bad stuff.
