Nicotine present in tobacco found in cigarettes reduces psychiatric, cognitive, sensory, and physical effects of schizophrenia, and also provides relief of common side effects from antipsychotic drugs.
1. Smoking lowers risk of knee-replacement surgery
After controlling for age, weight and exercise, the researchers were able to explain the slight protective effects of smoking for osteoporosis. It could be that the nicotine in tobacco helps prevent cartilage and joint deterioration.
2. Smoking lowers risk of Parkinson's disease
Numerous studies have identified the uncanny inverse relationship between smoking and Parkinson's disease. Long-term smokers are somehow protected against Parkinson's, and it's not because smokers die of other things earlier.
3. Smoking lowers risk of obesity
Smoking in particular, the nicotine in tobacco smoke is an appetite suppressant. The relationship between smoking and weight control is complex: Nicotine itself acts as both a stimulant and appetite suppressant; and the act of smoking triggers behavior modification that prompts smokers to snack less. Smoking also might make food less tasty for some smokers, further curbing appetite. As an appetite suppressant, nicotine appears to act on a part of the brain called the hypothalamus.
4. Smoking lowers risk of death after some heart attacks
Compared with non- smokers, smokers who have had heart attacks seem to have lower mortality rates and more favorable responses to two kinds of therapy to remove plaque from their arteries: fibrinolytic therapy, which is basically medication; and angioplasty, which removes the plaque by inserting balloons or stents into the arteries.
5. Smoking helps the heart drug clopidogrel work better
Clopidogrel is a drug used to inhibit blood clots for those patients suffering from coronary artery disease and other circulatory diseases leading to strokes and heart attacks. Smoking seems to help clopidogrel do its job better.
