Pain is so complex and weird that the role of smoking often gets lost in the mess of possibilities — two chaotic phenomena interacting, like storm fronts colliding. And that’s exactly why smoking is relevant to pain: smoking tobacco affects practically everything, and practically everything affects chronic pain, and so there’s bound to be overlap. And there is. Smoking is a major risk factor for chronic pain.123
Ironically, nicotine is also a pain-killer — but that short term effect is overwhelmed by the long term impact on pain.4
“Smoking was established long ago as a strong predictor of failure of pain treatment,” writes Dr. Tim Taylor, a chronic pain specialist. “Smokers are so difficult to treat that I will not accept smokers as patients.”
Smokers often assume that they’re mostly just hurting their lungs and risking cancer, but that is just the tip of the iceberg. Smoking compromises so many aspects of health — nearly all of them, really — that quitting is a vital pre-requisite for beating pain.
Doctors and smoking advice
Doctors are often maligned for not caring about “prevention”, and yet discovering the health risks of smoking is one of the clearest triumphs of scientific medicine, among so many others in the last two hundred years. In fact, probably nowhere else in medicine is it more obvious that doctors do care about prevention. Certainly my doctor cares.67
Ironically, it is often the accusers who ignore the clinical importance of factors like smoking in chronic pain, because they are preoccupied with their own pet theories about what causes pain …
Missing the smoking forest in the biomechanical trees
Many therapists (and patients too) often miss the forest for the trees. This forest represents an extremely important clinical consideration: smoking. The trees are the biomechanical explanations for pain that so many people get obsessed with: specific, “exciting,” and therapizable biomechanical causes of pain like crooked, asymmetrical, and degenerated anatomy. focusing on things like this is strong theme in the manual therapies like massage and chiropractic — but not a very good one. These sorts of explanations for chronic pain leave much to be desired.8
And they may be an unfortunate distraction from more basic and powerful explanations for pain. Like smoking.
Smoking is one of those big picture medical factors in pain — like insomnia, stress, or nutritional deficiencies — that can be the main reason an otherwise minor pain problem is so stubborn. It might be the reason a little biomechanical glitch hurts in the first place, instead of being painless like it is in other people.
One excellent example: smoking is clearly associated with shoulder pain and injuries (like rotator cuff tears).9 Think about that: smoking makes people tear their shoulder muscles more. That’s hardly the kind of vulnerability people expect from smoking. It’s also very likely that it’s a risk factor for frozen shoulder.
Smoking and breathing
Biomechanics may often overemphasized, while smoking is neglected as a consideration, but there is one scenario in which they may both be involved:
In addition to the many harmful effects on physiology, wheezing smokers may also painfully exhaust accessory breathing muscles in the neck, like the scalenes … which might cause more upper body pain than you’d ever guess (via the mechanism of “referred pain,” which the scalenes are unusually “good” at). This is just my own pet biomechanical theory of pain, but it’s reasonable: I explain it in much more detail in The Respiration Connection: How dysfunctional breathing might be a root cause of a variety of common upper body pain problems and injuries.
Smoking tobacco causes pain, and smoking marijuana probably relieves it. There are of course health risks associated with inhaling any kind of smoke, but certainly marijuana in moderation is pharmacologically safe.10 And, where legal, there are other good delivery mechanisms: edibles and vapourizing, most notably.
The efficacy of marijuana for pain is controversial — what about marijuana isn’t controversial? — but clearly there is a strong case to be made for it.

Over 3000 women who took comprehensive lifestyle and medical history questionnaires in 1976. A quarter century later, 136 of them reported a diagnosis of fibromyalgia. Their medical history was examined in more detail to look for correlations between fibromyalgia and diseases, lifestyle factors, and health behaviors. “Smoking as well as prevalent allergies, and a history of hyperemesis gravidarum [morning sickness, but much worse], seem to predict development of FM in women during 25 years of follow-up.” No correlation was found with the number of surgeries, ulcers, or medication usage.

This study added to the pile of evidence that smoking is “associated with low back pain, intervertebral disc disease” along with many other medical complications. Their conclusion, after studying the records of more than 5000 patients with “axial or radicular pain from a spinal disorder,” was that there is a “need for smoking cessation programs for patients with a painful spinal disorder.” Very likely both neck and back, of course.BACK TO TEXT

This is a common complaint we hear from alternative medicine advocates, especially from naturopaths. It is so wrong it hardly deserves an answer.

- “Structuralism” is the excessive focus on causes of pain like crookedness and biomechanical problems. It’s an old and inadequate view of how pain works, but it persists because it offers comforting, marketable simplicity that is the mainstay of entire styles of therapy.

Smoking is strongly linked to more shoulder pain and injuries (like rotator cuff tears, and probably frozen shoulder as well), which is weird. This seems to be excellent evidence of two principles:
- There doesn’t seem to be anything that smoking will not make worse.
- Musculoskeletal pain/injury that seems “mechanical” is often more about subtle biological vulnerability.
This review considered thirteen studies of shoulder trouble in about 6000 smokers out of 16,000 patients. The studies showed clear links between smoking and rotator cuff tears: more tears and worse tears, with more degenerative signs later on. That is, the “cuff” of muscles around the shoulder joint is apparently more fragile in smokers. They also found a link with unexplained chronic should pain and dysfunction. One experimental study showed that nicotine made rat shoulder tendons stiffer.

- Ware MA, Wang T, Shapiro S, Collet JP; COMPASS study team. Cannabis for the Management of Pain: Assessment of Safety Study (COMPASS). J Pain. 2015 Dec;16(12):1233–42. PubMed #26385201. ❐
Although we already have many reasons to suspect that cannabis usage is very safe, the more data the better on this topic, and particularly in the context of treating non-cancer pain. The results are good news, and completely consistent with other evidence. Ars Technica:
Almost every news story one reads about the use of cannabis as a medical therapy contains some variation of disclaimer saying ‘more research is needed’ into the longterm safety of medical cannabis use. Now a tiny bit of that ‘more research’ has been published in the Journal of Pain. The headline result was that there was NO INCREASE IN THE NUMBER OF SERIOUS ADVERSE EVENTS in a group that used cannabis for chronic pain when compared to a group that did not.
It’s hard to overstate how significant that kind of safety level is for any medication that helps with pain. Even the mildest over-the-counter analgesics come with serious risks (see How risky are NSAIDS?). Cannabis is not risk free — this study did find evidence of non-serious adverse events — but the total absence of serious adverse events is a big deal.
