This has been an issue for a long time now and it's about time we consolidated all of our information into one thread. As I find them (there are many), I'll add links to other relevant threads on this topic, and if you feel you have something to add, please do so we can put something together and save some people from themselves! 
I'm copying and pasting what I wrote in the beginners guide to heroin. This is written for BTH but applies to all pharmaceutical opiates, however the "cut" is referring to the inactive ingredients added to commonly abused prescription opioids such as oxycodone (OxyContin, Roxicodone, OxyNorm, Oxy IR, etc), hydromorphone (Dilaudid, Exalgo, HydromorphContin), oxymorphone (Opana, Numorphan, Numorphone), Methadone (Methadose), Morphine (Morphine, MSContin, Roxanol, MS IR, Kadian, Avinza) and various others.
NONE OF THESE SHOULD BE HEATED WHEN PREPARING FOR PARENTERAL INJECTION.
Black Tar Heroin:
According to the experience of many, and the science that back's it up, under most circumstances in the USA you do not heat heroin. Especially not powder heroin, but not tar either.
The reason you don't ever apply heat is, when you do apply heat tar, you introduce all the contaminates, cuts, and probably degrade the active ingredient a little bit while allowing all the precipitate matter to join the solution. YOU ARE SUPPOSED TO BE LEFT WITH VISIBLE "TAR" IN YOUR SPOON, ALL THE HEROIN HAS GONE INTO THE WATER. THE VISIBLE "TAR" IS INACTIVE INGREDIENT, LIKELY THE SUBSTANCE THAT YOUR HEROIN HAS BEEN CUT WITH. This is only difference between a hot shot and cold shot of heroin, hot shots DO NOT get you higher.
Don't be fooled by what you see, your eyes cannot see milligrams, but all the heroin has all gone into the cold water. Many people's eyes play tricks on them when they heat the solution and no longer cannot see the particulate matter, but it's is still there, but melted in with solution.
When you run a solution that was heated/cooked and not allowed to completely cool down in time, when you run it through the filter, the adulterants/contaminates/inactive ingredients slip right through the filter and into your syringe. Even though it may look clear to you, it is almost as dangerous as IVing without a filter, since the filter couldn't effectively filter out the particulate matter from the cooked/hot solution of heroin/water/melted cut.
Another common myth is that cooking your shots kills all bacteria eliminating risk of bacterial infection. This is false because bacteria thrive in wet, warm/hot environments, and if you actually applied enough heat to kill all bacteria, you would have degraded the active ingredient, heroin, significantly. So another reason to do cold shots: No added degradation of heroin. To minimize risk of bacterial infection, practice proper injection technique, absolutely EVERYTHING that comes in contact with the drug, your solution, your rigs, etc, must be sterile. When mashing the heroin with a plunger in cold water in your cooker or spoon, be EXTRA sure that you've sterilized the plunger, and have washed your hands with isopropyl alcohol, or even better use non-latex gloves. There are more germs on your fingers than most other parts of your body so it is VITAL that you maintain a sterile environment every step of the preparation and injection procedure.
--------------------------------------------------------------------------------------------------------------------------------
With pharmaceuticals it's important to remember that when you're prepping a shot of, for example, oxymorphone IR, there is up to 10mg of active ingredient hidden amongst hundreds to thousands of milligrams of inactive ingredients, and it's important to filter out as much of this as you can, using clean water.
See the inactive ingredients in medications and Pill-Mass Ratios (take note that it's from 2010 and new formulation pills may not be accurate, so if you have the means to contribute to this thread please do)

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.
