| The possible advantages of smoking:
In spite of the huge volumes of accumulated evidence about the hazards of smoking, scientific studies exist which talk about the benefits of smoking. Ulcerative colitis is observed in nonsmokers by two times more than in smokers. The Nicotine of tobacco smoke possesses anti-inflammatory properties. Data is available that nicotine, due to its action on the balance of mediators acetylcholine and dopamine in the CNS, reduces the probability of Parkinson and Alzheimer diseases, however, scientific research works are carried out with diametrically opposite conclusions. Data is available, which says that smoking reduces the risk of growth of endometrial cancer (in connection with proved anti estrogen action of nicotine), but these studies are challenged.
Frustration has turned a Chinese chimpanzee from a mild-mannered simian into a problem primate who smokes cigarettes and spits at visitors, the Xinhua news agency says.
"The chimp is spitting at tourists and smoking," Xinhua quoted a boy visiting the zoo. "Just now a tourist threw a cigarette just outside the cage, she tried to get the cigarette butt with a stick."
