Secondhand Smoke, Firsthand Ignorance

As the smoking ban marches on here in Charleston, South Carolina, as have similar bans across the country, anti-smoking activists have been able to implement such legislation by claiming they have science on their side. By convincing a significant portion of the population that secondhand smoke is not merely annoying, but a serious health risk, anti-smoking activists have been victorious, while business owners have been forced to bear the cost of lost rights and revenue. This is a shame, because gutting the primary argument of smoking ban proponents from the get-go - the health argument - might have produced an entirely different outcome.

Nicotine Lessens Symptoms Of Depression In Nonsmokers

Nicotine may improve the symptoms of depression in people who do not smoke, Duke University Medical Center scientists have discovered.

Nicotine Found To Protect Against Parkinson's-like Brain Damage

New research suggests that nicotine treatment protects against the same type of brain damage that occurs in Parkinson's disease. The research was conducted in laboratory animals treated with MPTP, an agent that produces a gradual loss of brain function characteristic of Parkinson's. Experimental animals receiving chronic administration of nicotine over a period of six months had 25 percent less damage from the MPTP treatment than those not receiving nicotine.

Nicotine helps Alzheimer's and Parkinson's Patients

Nicotine is a widely seen drug found in tobacco products. It is usually associated with the negative effects of smoking, including the addiction and cravings. However, nicotine can be helpful for people with pathological disease states such as Alzheimer's disease, Parkinson's disease, attention deficit/hyperactivity disorder and schizophrenia. A recent study done here at UVM investigated the cognitive improvements of three groups: smokers, normal volunteers, and contrasts those with trials of nicotinic stimulation in pathological disease states. Chemical receptors for nicotine are found all throughout the central nervous system, and stimulating parts of the brain with nicotinic acid have shown to be vital to memory function. Nicotinic acid is a B vitamin found in yeast, liver, eggs, and other foods and is also known as niacin, or vitamin B3.

Nicotine Benefits

Researchers have long been aware that fewer smokers get Alzheimer's and Parkinson's diseases than non-smokers. Up to April l992, of the 17 studies on Alzheimer's and smoking which had been published in peer-reviewed journals, 13 reported a reduced risk for smokers and only four found no difference between smokers and non-smokers. Similar findings have been published on the effect of smoking and Parkinson's disease.

Mechanism of nicotine's learning effects explored

While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory - a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder.

A key problem in designing such drugs has been that little was known about the detailed mechanism by which nicotine exerts its learning-enhancing effects.

Now, researchers have discovered important details of how nicotine adjusts the signaling properties of neuronal wiring to enhance memory. Such signaling properties include the strength of the connections by which one neuron triggers another. Huibert Mansvelder and colleagues reported their findings in the April 5, 2007, issue of the journal Neuron, published by Cell Press.

Has California's Anti-Smoking Campaign Reduced Lung Cancer Rates?

California authorities have recently claimed that, as a result of their anti-smoking campaigns, there has been a marked reduction in lung cancer death rates (LCDRs) in California. No doubt, there has been a reduction, but I suggest that it's entirely unrelated to smoking!

Cannabis joints damage lungs more than tobacco - study

A single cannabis joint may cause as much damage to the lungs as five chain-smoked cigarettes, research has found. Medical examinations of cannabis and cigarette smokers found the drug increased specific lung problems, including obstructed airways and hyperinflation, a condition where too much air remains in the lungs when a person exhales.

Comment: What is happening? Is this yet another way of distracting away from the 3 million chemicals that we are exposed to in our modern living by blaming lung diseases on smoking tobacco and this time on smoking cannabis?

Nothing to do with the air pollution or the toxic environment in which we live. And not to mention pesticides, herbicides and other toxins in our often lifeless food.

It is so nice and convenient when it can all be reduced down to one thing and especially when the authorities can lay the blame 100% on the individual.

Parkinson's Disease: Nicotine Could Help; Pesticides Harm

The Parkinson's Institute recently announced new findings concerning the role of environmental factors in the development of Parkinson's disease.

Highlights of the research include:

The role of pesticides (eg. Paraquat and Dieldrin) as potential risk factors for Parkinson's disease, a role suggested by both epidemiological statistics and laboratory evidence.

The threat of toxic agents to damage neurons by causing the accumulation of harmful proteins.

Intraneuronal protein aggregates as markers of Parkinson's pathology, based on work carried out at The Parkinson's Institute indicating that these aggregates could be formed as a consequence of toxic exposure.

The importance of targeting a specific protein, alpha-synuclein, in order to achieve neuroprotection in Parkinson's
The role of inflammation in the development of Parkinson's disease and the possibility that anti-inflammatory drugs could be beneficial to patients.

The possibility that nicotine may act as a neuroprotective agent.

Researchers Light Up for Nicotine, the Wonder Drug

Smoking may be bad for you, but researchers and biotech companies are quietly developing pharmaceuticals that are decidedly good for brains, bowels, blood vessels and even immune systems -- and they're inspired by tobacco's deadly active ingredient: nicotine.
