Written for opiophile, but decided I'd post it here as well
Introduction & Context
I recently attended a pill injection workshop in Australia, among the people at this workshop, there was a man called Dr. Bruno Raimondo, him and his team are running research into opioid pills such as OxyContin, MSContin and Subutex and the effectiveness of filtering. In the morphine forum I already summarized a document he did, I managed to obtain a
copy of the slides he used at the presentation, although he has not released the formal version (which I will link to when he has) of the research, the slides he has emailed me are sufficient for the information people need to know.
Too long didn't read:
Don't heat pills, 2-3ml of water soaking your finely powdered pill, with a 1ml rinse through your filter (SHOULD be using a wheel filter) will give you the best results. Wheel filters are necessity they don't retain any drug (95-99% is let through, cotton filters let through less). Expect health problems down the road if you shoot cotton filtered pills.
Harms of pill injection
Injecting pills (or anything) can result in contaminants entering your body such as insoluble particles or bacteria and fungi. These things can irritate and inflame tissue and veins, cause infections in skin/muscle (granuloma, abscess). They can also result in local and systemic infection from the bacteria/fungi.
Insoluble and undissolved particles can cause microcirculation capillaries (5-10um) to become blocked, they clog up in the heart and lungs. Granulomas in the lungs are caused by inflammation which leads to scar tissue (fibrosis). Congmomerate masses lead to restrictive lung disease and pulmonary hypertension. The particles also reach other organs (liver, kidney etc).
Key particles in pills (OxyContin, MSContin, Subutex)
Other insoluble particles included are:
Magnesium stearate (5-30um)
Titanium dioxide (100um clumps) (ms, oxy)
Other particles that change form in heat are:
Stearyl alcohol MP is 59*C (ms, oxy)
Eudragit RS 30D clumps at >30*C (oxy)
All these particles cause problems in your heart, lungs and other organs, the chemicals that change form in heart are the reasons why pills should NOT be heated, and you will soon find out there is no advantage to heating.
Why pills shouldn't be heated
As you can see, of these images under a microscope, heating pill solutions cause enourmous particles to dissolve in the mix. These particles will pass through the filter (wheel or cotton) and recongeal, precipitating out in your filtered mix or veins.
Ok so I shouldn't heat, what about Rollie cigarette filter filtering (or cotton).
For comparison: MSContin rollies reduce particles >5um by 60%.
What about the drug retained?
For subutex 97% of the drug is returned in this process.
Drug is not retained in the filter after this, even if the filter is wet.
.
Wheel filters (and why they rock!)
Here is the solution of two pills under a microscope before and after wheel filtering
But how many particles are removed by the wheel filters?
But what about drug recovery
For subutex drug recovery is 99%
*Note: One of the researches reminded me to say that when they first did these tests, their technique with wheel filters was poor, and that morphine recovery is more like 95-99%
So as you can see, using wheel filters removes all the particles that cause harm (basically), with a rinse of water after first filter, you can retain 95-99% of the drug (better then a cotton/rollie filter) while removing 99% of the particles that cause harm, and heating is generally a bad idea that does NOT help at all, and does more harm then good.
Note: Hand rolled cigarette filters filter to about 50um.
Another document for the national drug safety council, which focused mainly on morphine and wheel filters, also contains a lot of information. It is located
here.
I also posted this in Australian drug discussion but was told to also post it here.
had to pull out half way thru cuz of the burning pain.... No miss but now hand is slightly swollen, skin feels stiff almost, and is red and blotchy, almost welt looking blotches. My face instantly flushed but that subsided. Now my hand is throbbing! Any advice on how to treat it/ how serious this is , would be so greatly appreciated
