I took a look at that CO paper. It is a great example of just how divorced from scientific reasoning people who do epidemiology are. First, there are tons of occupational studies that look at a lot of people with high CO exposure. You might think that, perhaps, if this phenomenon were true then someone would have noticed it before. Second, just within the bounds of the paper, they do not seem to realize that -- contrary to all that we know -- their results suggestion that serious combustion air pollution is harmless (and beneficial by this one measure), and by extension, smoking must not really be all that bad for you. If having high levels of CO in one's body, and it is caused by burning organic matter (something that is right there in their words, but they somehow forget it), and it does not seem to have bad results, then rural air pollution (from a lack of emission controls and from indoor solid-fuel cooking) is just fine. Gee, I wonder who might like to be able to claim that. Also, so is smoking. And third, the plausibility that oxygen deprivation protects against PD (which is really the only apparent mechanism for the causation they claim) is, well, a bit of a stretch.

I did not read carefully enough to form an opinion about whether this is the result of measurement error and/or confounding (possibly be likelihood of diagnoses across populations), or if there is some kind of survivor bias, or if they just didn't measure smoking well, or if the whole thing was just fraudulent.

I hate the meddling EU and Swedish state with a passion. In another few years, I'll run out of the 72mg nicotine base that I keep in my freezer. Here in Sweden, a 10ml bottle of EU compliant e-juice is the equivalent of £6.78 per bottle. :o
