NICOTINE

Lots of those who claim that smoking can harm health, of course supported by intensive research with maximum results.
But below I will write some positive effects of nicotine (sorry I've forgotten the source):

1. Smoking Reduces Risk of Parkinson's
Considerable evidence suggests that smoking against Parkinson's disease. A recent study adds strong evidence that reported previously that smoking can protect people from Parkinson's disease. In particular, new research shows a temporal relationship between smoking and reduced risk of Parkinson's disease. That is, the protective effect against Parkinson decreases after smokers stop smoking.

2. Smokers are more powerful and faster recovery from heart attacks and strokes
Another major study showing the benefits of smoking, the benefits of restenosis or narrowing of blood vessels that cause the blood flow becomes restricted, such as blood vessels to the heart (cardiovascular disease) or to the brain (stroke) Smokers have a better chance of survival and a longer recovery fast.

3. Smoking reduces the risk of gum disease is severe shrinkage
It used to be mentioned that tobacco is the root of all problems of the teeth and mouth disease. Whereas one study suggests that smokers actually had a lower risk of gum disease.

4. Smoking prevent asthma and other allergic diseases
A study of two generations of Swedish residents demonstrated in the analysis of multiple variations, some children of mothers who smoked at least 15 cigarettes a day tended to have lower odds for suffering from allergic rhino-conjunctivitis, allergic asthma, atopic eczema and food allergy, compared with children children of mothers who never smoked. The children of fathers who smoked at least 15 cigarettes a day had the same tendency.

5. Nicotine kills germs that cause tuberculosis (TB)
Nicotine may one day be an alternative that surprising as the hard-TB drug treatment, says a researcher from the University of Central Florida (UCF). These compounds stop the growth of TB germs in a laboratory test, even when used in small quantities only, said Saleh Naser, an associate professor of microbiology and molecular biology at UCF. Most scientists agree that nicotine is a substance that causes people to become addicted to cigarettes.

6. Smoking is a rare skin cancer prevention
A researcher at the National Cancer Institute found that smoking can prevent the development of skin cancer that afflicts mainly the elderly in the Mediterranean region of Southern Italy, Greece and Israel.

7. Smoking reduces the risk of breast cancer
A new study in the journal of the National Cancer Institute (May 20, 1998) reported that a specific gene mutation carriers (who tend as a carrier of breast cancer), who smoked for more than 4 pack years (ie, the number of packs per day multiplied by the number of years of smoking duration ) was statistically significantly decreased by 54 percent in breast cancer incidence when compared with carriers who never smoked. One of the strengths of this study is that the reduction in the incidence of exceeding the threshold of 50 percent.

8. Nitric Oxide in reducing nicotine colitis
Nicotine reduces circular muscle activity, particularly through the release of nitric oxide, in the case of ulcerative colitis (UC) or intestinal inflammation. These findings may explain some of the therapeutic benefits of nicotine (and smoking) to the UC and could explain the dysfunction of colonic propulsion in active disease.

9. Effects of transdermal nicotine on cognitive performance (thinking) people with Down Syndrome
A study on the effects of nicotine-agonist stimulation with 5 mg of skin tissue implants, compared with placebo (drug control), on cognitive performance in five adults with the disorder. Improvements possibly related to attention and information processing seen in Down syndrome patients compared with healthy controls.
Down syndrome is a disease caused by abnormalities in chromosome 21 at band Q22 SLC5A3 gene, which can be recognized by looking at a fairly typical clinical manifestations. Disorder which affects the physical growth and mental retardation of children was first recognized in 1866 by Dr. John Longdon Down.

10. Smoking is good for pregnant women to prevent hypertension in pregnancy and maternal-child transmission of Helicobacter pylori infection

3. Consumption of white soda
4. Eat fruits that contain antioxidants such as grapes, tomatoes, strawberries and others.
