How can nicotine be good for health??

[Khushboo]

By now the health hazards of smoking and tobacco use are well known. Smoking is the chief preventable cause of death all over the world and a major contributor to many types of cancer, heart disease and other serious or potentially fatal conditions. Cigarettes are also expensive, addictive and they leave a bad odour. However, medical researchers have begun to shown interest in one of the most reviled components of cigarettes --nicotine. And they're interested in this potent, powerfully addictive substance for its health benefits.

Over the past decade, new research has taught us more about how nicotine affects the brain and the body. Some of it is good news -- for example, a lower incidence of Alzheimer's disease in smokers. Research has pointed to a compound called acetylcholine as the reason. Nicotine is structurally similar to acetylcholine, a naturally-occurring compound that serves as a neurotransmitter. In one study, a group of Alzheimer's patients were given nicotine patches and they maintained their cognitive abilities longer and even recovered lost cognitive function. A follow-up study indicated that nicotine may also boost cognitive abilities in elderly people who aren't suffering from Alzheimer's but who are experiencing the typical mental decline associated with old age.

Contrary to popular opinion, the study showed that nicotine actually boosts the growth of new blood vessels. The discovery may lead to new treatments for diabetes. Many people with severe diabetes experience poor circulation, which can lead to gangrene and ultimately, limb amputation.

While no nicotine-derived drugs are available yet, many are in the development or testing phases. The variety of conditions being studied reflects the excitement felt in the scientific community for the potential of nicotine: anxiety, depression, Alzheimer's, Tourette Syndrome, ADHD, Parkinson's disease, diabetes and schizophrenia.

These studies point to potentially positive aspects of nicotine, but what can we do with this information? Surely people shouldn't start smoking for their health. In one form, they're highly dangerous substances; in another, they're vital, even life-saving, medical treatments.

............but nicotine is a potent vasoconstrictor, so smoking should be strictly quitted after the limb reconstruction surgery,otherwise ischeamic necrosis ,due to vasoconstruction, is inevitable.

The studies are still going on this, so nicotine derived drugs are not available till yet but the researchers committee has published this report.

Lets see what happens next when this drug will be available in the market and whether it will be effective or not???

ahem..
isn't most of the pathologies tht are related to smoking due to the other ingredients like tar... instead of by nico...
i mean nico is the reason for the psychological feelings but tar, which i think is added so that the cigs burn well, is responsible for the pathologies.

enlighten me.

When a person inhales cigarette smoke, the nicotine in the smoke is rapidly absorbed into the blood and starts affecting the brain within 7 seconds. In the brain, nicotine activates the same reward system as do other drugs of abuse such as cocaine or amphetamine, although to a lesser degree. Nicotine's action on this reward system is believed to be responsible for drug-induced feelings of pleasure and, over time, addiction. Nicotine also has the effect of increasing alertn

Nicotine's action on this reward system is believed to be responsible for drug-induced feelings of pleasure and, over time, addiction. Nicotine also has the effect of increasing alertness and enhancing mental performance. In the cardiovascular system, nicotine increases heart rate and blood pressure and restricts blood flow to the heart muscle. The drug stimulates the release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the "kick" from nicotine. It also promotes the release of the hormone beta-endorphin, which inhibits pain.
People addicted to nicotine experience withdrawal when they stop smoking. This withdrawal involves symptoms such as anger, anxiety, depressed mood, difficulty concentrating, increased appetite, and craving for nicotine. Most of these symptoms subside within 3 to 4 weeks, except for the craving and hunger, which may persist for months.
