After having established that smoking has a protective effect against Parkinson’s disease in men, there is always the possibility that women may yet confirm that smoking is an absolute evil that is absolutely no good for your health. Too bad for the ideologues, it didn't pan out, results suggested smoking protects women from Parkinson’s as well.
"In women, the age-adjusted rate ratios (95% confidence intervals) for Parkinson's disease relative to never-smokers were 0.7 (0.5, 1.0) for past smokers, and 0.4 (0.2, 0.7) for current smokers. In men, the age-adjusted rate ratios for Parkinson's disease relative to never-smokers were 0.5 (0.4, 0.7) for past smokers, and 0.3 (0.1, 0.8) for current smokers.
In both cohorts, the strength of the association decreased with time since quitting (among past smokers), increased with number of cigarettes per day (among current smokers), and increased with pack-years of smoking. These prospective findings confirm that an inverse association between smoking and the incidence of Parkinson's disease exists in both men and women."
If antitobacco weren't a religion, Big Pharma would get in on the tobacco trade, heavy on the TV ads: “Smoke every which way to keep Parkinson's at bay!” or "Nine out of ten doctors say: 'Never quit!' ". Of course such prescriptions would include a dose of pleasure and Healthists will never recommend that!
