Theories abound to do with reasons why, but a study of men with osteoarthritis showed them at knee pain levels of 60% after smoking versus 45% without.
One theory is that people are more of a pain when they smoke — as in, their pain threshold is lower.
Most of the others relate to increased stress & poison levels in the smokers.
Whatever the cause and connection, the scientists are excited because smoking is, as they term it, a “modifiable risk factor.” Stop smoking, and perhaps the joints will benefit.
They also found that cutting back & using nicotine replacements enabled many of their subjects to kick the habit.
This contrasts with US findings, which say that quitting has to be done abruptly.
