If you have 30mg Oxy IR’s and looking to IV something go with those. These are easy to do with just cold water and a cotton filter.
I have never tried the crisping method with the morphs, but I would stay away from it as I personally do not think it works and is not worth the risk without a micron filter.
For the MS Contin, crush the pill to a fine powder, heat about 150 units of water in spoon to a rolling boil, dump in powder and stir quickly, add a little more heat, drop in cotton and suck up quickly. Let the solution cool completely and then re filter with a micron filter.
That’s the best I can tell you but again with the brand you have it does not work very well and I have never had much success.
Just stick with the oxys.
I'd agree with this post from personal experience.
I've IV'd pretty much every brand of MS Contin available in the US with varying degrees of success.
The method posted in the quote above works, though I don't stir after dumping in the powder.
I also after sucking up the solution, do a second cook with another 150 units that I put into a 2nd needle.
I then micron filter both the solutions & end up with 2 - 3 micron filtered shots.
2 - 3 shots using 1ml insulin syringes that is.
If I have the proper points for my luer locks I'll just use a 3ml rig & a 31 tip to do it all at once.
It really just depends on tolerance, as IIRC Morphine is soluble at 65mg per ML.
Thus depending on the amount of Morphine involved the amount of water needed & the size of the resulting shot would vary.
As stated by the above poster, be sure to let the solution cool completely before micron filtering.
If you do not cool the solution completely, even with a micron it seems you end up with a slightly "foamy" solution.
So be sure to cool the solution before micron filtering.
I've had decent success with this method but it is slightly hit or miss.
As sometimes the filter does seem to clog or some particulates seem to get through.
In which case I usually just micron filter a second time with another filter.
Again though as the above poster mentioned 30mg IR Oxycodone's are easier to IV.
I myself just crush, backload in a 3ml Luer Lock, suck up water, shake, attach micron, filter & have at it.
Relatively easy compared to working with ER Morphine.
Hope the above information helps you & also helps to confirm the above post.
