Nicotine and Dementia - Cigar anyone?

"A woman is an occasional pleasure but a cigar
is always a smoke.” - Groucho Marx 


I smoke a cigar now and then. Occasionally, some ill-informed non-smoking do-gooder tries to explain, usually at great length, just how bad smoking is for my health. I wait patiently as I enjoy the unparalleled pleasures of my cigar, and when they eventually finish, sure that they have convinced me, I reply, "I will die from complications of dementia long before any possible result of cigar smoking. In addition, nicotine in the form of my cigar serves to alleviate my symptoms, and is in effect a treatment for my disease. Want another drink?" 

...and for those really annoying people who need proof:

Nicotine clues for dementia treatment

14. July 2008 15:35

A team of London scientists have found clues for the potentially therapeutic benefits of nicotine on learning, memory and attention while minimising the risk of addiction. The research announced in Geneva Monday will assist the search for new drugs for dementia.

"Nicotine, like many other drugs, has multiple effects some of which are harmful whereas others may be beneficial," said Professor Ian Stolerman from the Institute of Psychiatry, King's College London. Previous research has revealed these cognitive effects in humans and in laboratory animals. "They are small effects and," he warned, "for healthy people they do not outweigh the harmful effects." The pharmaceutical industry has striven to discover nicotine-like substances for conditions such as Alzheimer's disease. Nicotine itself is difficult to administer by conventional means. The differences between doses that produce cognitive and toxic effects are small and, most significantly, there is also high risk of addiction. The balance, however, between costs and benefits is much more favourable for people with serious illnesses such as dementia. Speaking at Europe's biggest neuroscience conference, Professor Stolerman explained that newer substances are based upon the chemical structure of the nicotine molecule. Research in rats has shown a nicotine-induced improvement in sustained attention to visual stimuli. The King's College team studied the underlying mechanisms that produced this change and have helped to identify the roles of nicotinic receptors - the proteins on cells that respond to nicotine - as well as the involvement of several chemicals in the brain, including dopamine, noradrenaline, glutamate and serotonin. "We found several similarities and only small differences between the cognitive mechanisms and those involved in the addictive effects of nicotine," said Professor Stolerman. "The cognitive 'boost' that many smokers experience from nicotine probably contributes to the reason people smoke cigarettes, so it may not be possible to totally prevent addiction. Nevertheless, the potential for abuse of a medicine based on a pure nicotine-like substance is likely to be very small." The new knowledge about mechanisms of nicotine action may speed the discovery of agents that are more effective as cognitive enhancers than nicotine itself, with longer-lasting effects. "This is a promising stage in the years of research that have endeavoured to separate the beneficial from the harmful effects of nicotine," Professor Stolerman concluded. 

But, more importantly, a beautiful woman recently remarked over a glass of fine apple wine how she loved the smell of my cigar, and in spite of anything Groucho may have thought, that alone would be reason enough to smoke one now and then. 

So my advice is,  if you don't smoke, don't start, but if you have dementia, who gives a shit?
