Researchers are closing in on a non-addictive opiod-based pain-killer with limited side effects:
[...] [An] international team [has] captured the crystal structure of the kappa opioid receptor—critical for providing pain relief—in action on the surface of human brain cells. The researchers also made another important discovery: a new opioid-based compound that, unlike current opioids, activates only the kappa opioid receptor, raising hopes that they may develop a painkiller that has no risk of addiction and, therefore, none of the devastating consequences and side effects that accompany it.
The findings were published Jan. 4 in the journal Cell.
[...] Currently, most opioids bind to several opioid receptors on the membrane of brain cells, which has its share of drawbacks. They alleviate pain but cause a range of side effects, from nausea to numbness, constipation, anxiety, severe dependency, hallucinations and even death by respiratory depression.
In this study, the computer models revealed the formulations that would create the strongest bond between the ligand and the kappa opioid receptor without affecting other receptors.
Katritch said the latest research may pave the way for a major drug breakthrough.
"We have already found the structure of the inactive kappa opioid receptor highly useful for discovering potential candidates for a new painkiller," Katritch said. "Now with the structure of the active receptor, we have a template for designing new types of pain medications that have no disruptive side effects for patients and would reduce the burden that opioid addiction has placed on society."

Having known several people who got addicted to painkillers after receiving prescriptions for oxycodone or similar compounds from their doctors, this can't happen soon enough.

You're confusing dependency and physical addiction. I became dependent on the pain relief, that's a psychological thing. But my body became addicted, dependent in a very physical way. Enough became not enough. Efficacy diminished. You crave more, physically. And then, trying to come off of them, that causes pain in its own way.
I didn't go to the street for more. I said I'm not living my life that way, and I stopped. I deal with the pain in other ways. If one way was a non-addictive opioid I'd give it a try. Addictive, physically? No way. Not unless I get cancer or have major surgery. And then with caution.
Round about way to my point which is this: there are multiple facets to dependency.

Good point, but this is what I wonder: is it the pill that is addictive, or the addict that is prone to addiction to the pill? Clearly, opioids do bring on physical addiction, and I could tell from that taste of cocaine I had in college that it was too good to tempt fate by using on a regular basis, but... how will they classify a painkiller as not-addicting? What portion of the population needs to be able to put it down, and after how long using?
I had a bad injury a few years back, then some stitches that didn't dissolve (extra fun, 'cause the non-dissolvers pull out clean and easy, but a partially dissolved stitch is like pulling out an embedded part of you...) I was getting by fine without the painkillers, so I didn't take them, but after that day in therapy when they pulled one dissolved stitch (with like 5 to go) and stopped because the pain was about a 973 on a scale of 1 to 10, I figured I'd get smart and take my painkillers to peak at the next session. Sure enough, the oxy or whatever they gave me blocked the pain, they pulled about 3 of the stitches and I didn't feel any pain, but I had broken out in heavy cold sweats, turned grey and was about to pass out from the "c-fiber" pain messages that weren't being blocked. Still, 3 stitch removing sessions were better than 6.
I'm lucky that I mostly only deal with what I would call chronic discomfort... if anybody experiences that fingernail ripping off pain on a chronic basis, man - I just can't imagine, but I can imagine how anything that could block that would be an indispensable part of life.

Chronic pain is not cool. It's hard to live with and it adds to depression, if not causes it. For me, the answer was to do nothing that stressed my back. The odds on surgery were too low to take the risk. So, I just changed my lifestyle. That helped but something as simple as washing dishes can be quite the pain.

On the other hand, most people do not have chronic pain. They have incident pain, related to an injury or surgery.
People heal and get past most incident pain, usually in 3 to 4 weeks for everything except burns.
Any Opioid replacement that won't addict you in that amount if time would be a godsend.
Chronic pain should probably be addressed surgically rather than chemically. If a nerve is going to do nothing
but trigger pain forever, then shut that thing off and live with the dangers of that.
No, you are mistaken. I've always had this sig.
