I also read that they are studying nicotine now as a possible medication to help alzheimer's patients and parkinson's sufferers as well as helping schizophrenics.
Absolutely correct, HeatherC.
While it is true that nicotine has some negative side-effects, it is not the nicotine that causes the vast majority of health problems associated with smoking. In fact, according to the scientific and medical community, nicotine, without the other 4,000 chemicals in cigarette smoke, has many potential therapeutic and medicinal properties:
Nicotine's mood-altering effects are different by report: in particular it is both a stimulant and a relaxant.[31] First causing a release of glucose from the liver and epinephrine (adrenaline) from the adrenal medulla, it causes stimulation. Users report feelings of relaxation, sharpness, calmness, and alertness.[32] By reducing the appetite and raising the metabolism, some smokers may lose weight as a consequence.[33][34]
When a cigarette is smoked, nicotine-rich blood passes from the lungs to the brain within seven seconds and immediately stimulates the release of many chemical messengers including acetylcholine, norepinephrine, epinephrine, vasopressin, arginine, dopamine, autocrine agents, and beta-endorphin.[35] This release of neurotransmitters and hormones is responsible for most of nicotine's effects. Nicotine appears to enhance concentration[36] and memory due to the increase of acetylcholine. It also appears to enhance alertness due to the increases of acetylcholine and norepinephrine. Arousal is increased by the increase of norepinephrine. Pain is reduced by the increases of acetylcholine and beta-endorphin. Anxiety is reduced by the increase of beta-endorphin. Nicotine also extends the duration of positive effects of dopamine[37] and increases sensitivity in brain reward systems.[38] Most cigarettes (in the smoke inhaled) contain 1 to 3 milligrams of nicotine.[39]

And studies show that nicotine may be an important source of treatment for a variety of illnesses and conditions.

According to the American Academy of Neurology, mild cognitive impairment is a precursor to Alzheimer's disease. It may seem strange that nicotine could have a "good" side, but Paul Newhouse, M.D., from the University of Vermont, says indeed, it does. He says, "Nicotine can improve learning. It can improve attentional performance. It can improve visual performance. It can improve sustained attention over time."
THE PROMISE OF NICOTINE: Researchers like Dr. Newhouse across the country are finding that nicotine may benefit more than just Alzheimer's disease and dementia. They're also finding beneficial effects for people with Parkinson's disease, ADHD, Tourette syndrome and more. In a study on Parkinson's disease, Dr. Newhouse found nicotine improved both cognitive and motor performance. Recent research by Dr. Newhouse's colleagues at UVM suggests there also may be a specific role for nicotinic stimulation for both children and adults with ADHD.

Many people think nicotine causes cancer, or other diseases. But Just the opposite is true, says Dr. Virginia Reichert, Lead investigator for the North Shore-Long Island Jewish Health System in Great Neck, New York. Nicotine does not cause cancer, . . . Its the cigarette smoke that contains carcinogens, neurotoxins and other toxins.
