"In February, the Australian Bureau of Statistics published national health survey taken in 1989-90. To much surprise, it revealed that, generally, the health of smokers is better than that of many former or non-smokers. Unsurprisingly, the worst sufferers from hypertension caused by stress were the ex-smokers (16.1 per cent) and the "never smoked" (13.4 per cent); the steady smokers registered 7.4 per cent.
It is well known that smoking, particularly at work, relieves stress, and to outlaw it increases demands on hospital beds. Even the US Surgeon General, in 1964, recognised that Parkinson's disease (a degenerative disorder ofthe nervous system) occurred at around half the rate among smokers. In the International Journal of Epidemiology, in 1991, a review of 11 studies showed that non-smokers suffered 50 per cent more Alzheimer's disease than smokers. And researchers at Erasmus University Medical School, Rotterdam, found that more non-smokers had early-onset dementia than smokers.
In The Times last September, Dr. James Le Fanu wrote: "Smokers have a 50 per cent reduced risk of developing Alzheimer's and the more smoked, the greater the protection." The New England Journal of Medicine.in 1985, reported that endometrial cancer of the womb occurs at around 50 per cent the rate among smokers as non-smokers. Colon cancer and ulcerative colitis also seem to be about 30 and 50 per cent respectively less frequent among smokers according to articles in the Journal of the American Medical Association and in the New England Journal of Medicine, in 1981 and 1983. The American government's first Health and Nutrition Examination Survey has found that osteoarthntis is five times less likely to occur among heavy smokers than non-smokers."

"A statistically significant inverse relation between smoking and Alzheimer's disease was observed at all levels of analysis, with a trend towards decreasing risk with increasing consumption (p=0.0003). A propensity towards a stronger inverse relation was observed among patients with a positive family history of dementia."

"A negative trend for smoking was observed when comparing patients with Alzheimer's disease and controls: the risk of Alzheimer's disease decreased as the number of cigarettes smoked daily increased. After exclusion of patients and controls with a history of atherosclerotic cardiovascular disease, the relative risks of Alzheimer's disease for smoking 1-10, 11-20, and more than 20 cigarettes daily were 0.81 (0.44 to 1.49), 0.67 (0.34 to 1.32), and 0.26 (0.11 to 0.61), respectively. A similar trend was observed when comparing patients and controls for the number of pack years they had smoked. The relative risk of Alzheimer's disease was 0.38 (0.13 to 1.10) for those who had smoked for 1-10 pack years, 0.29 (0.08 to 0.98) for 11-30 pack years, and 0.22 (0.06 to 0.77) for more than 30 pack years.

Ulceratieve colitis
"Twelve of 31 patients treated and 3 of the 33 patients given placebo showed improvement ( in stool frequency, rectal bleeding, etc.) which indicates that smoking does appear to help reduce symptoms in some of the patients with ulcerative Colitis."
Annals Of Internal Medicine, March 1, 1997
[..]
The relative risk of ulcerative colitis among current cigarette smokers as compared with nonsmokers was 0.6 (95 percent confidence interval, 0.4 to 1.0); however, among former cigarette smokers it was 2.0 (95 percent confidence interval, 1.1 to 3.7). These values remained after adjustment for socioeconomic factors and for coffee and alcohol consumption.

- Smoking improves human information precessing.
- Higher nicotine cigarettes produce greater improvements [in information processing] than low-nicotine cigarettes.
- Nicotine tablets produce similar effects.
- Nicotine can reverse the detrimental effects of scopolamine on performance
- Smoking effects are accompanied by increases in EEG arousal and decreases in the latency of the late positive component of the evoked potential."
