A 26-year follow-up study of 8,006 men enrolled in the Honolulu Heart Program examines the effect of cigarette smoking on the risk of developing idiopathic Parkinson's disease, and observes:

"Men who had smoked cigarettes at any time prior to study enrollment in 1965 had a reduced risk of developing idiopathic Parkinson's disease (relative risk = 0.39). Examination of smoking by pack-years revealed an apparent dose-response effect on the risk of idiopathic Parkinson's disease, but not on the age of onset. Coffee drinking was also associated with reduced risk, apparently because of its association with cigarette smoking."

The abstract pays the mandatory ideological lip service to the antismoking religion by indicating, implicitly (and in the assumption, we may add, that these findings and those on other diseases are not junk science) that it is better to die of Parkinson's disease than of lung cancer (!):

"Although the detrimental health effects of cigarette smoking would far outweigh any possible protective effect for smoking and Parkinson's disease…"

Once the “smoking-is-bad-for-you” antismoking bit has been recited (probably essential to get published), and after you have been advised by the "experts" of "public health" on what kind of death you must choose, we finally get to the conclusions:

"...the association of smoking with apparent protection may contribute to understanding the underlying pathogenetic mechanisms."

... Just by the way, but the message must still be, smoking is entirely evil.
