While smoking may be one of the worst things you can do for your health, certain benefits of nicotine are being proven by new research. Parkinson's disease, an affliction primarily of the middle-aged to elderly, may turn out to be one condition to which nicotine shows great promise.
Nicotine's primary impact upon the symptoms of Parkinson's disease seems to be the effect of its relationship to dopamine release. Dopamine is a neurotransmitter partially related to the experience of pleasure, released upon the consumption of marginally or explicitly euphoric substances such as alcohol, nicotine, caffeine and most illicit drugs. In addition to producing euphoria when released in excess, however, dopamine also is related to muscle control, which is why its notable lack is so visibly evident in sufferers of Parkinson's disease. The tell-tale shake is the result of too little dopamine, a condition treated presently by a medicine known as L-dopa, which metabolizes to dopamine in the brain.
To be most clear, however, nicotine has not yet been thoroughly tested as a treatment for Parkinson's, either. In fact, the benefits of the drug are mostly based upon correlational study, rate of Parkinson's contraction as compared to smoker-nonsmoker status or amount of tobacco smoked. Some studies indicate that this result may in fact be related to a somewhat deterministic concept of personality, rather than unconscious self-medication.
You see, because Parkinson's disease is symptomized by an inability to produce the proper amounts of dopamine, there is some speculation that this inability exists in those likely to contract the disease long before the appearance of symptoms, but to a lesser degree. This would provide those "marked" as future Parkinson's sufferers with a greater physiological appreciation of these pleasure-inducing substances, making them less likely to incorporate them into habit or to consume them to the point of addiction.
While this study's distrust of correlational observation is commendable, there is some extreme biological determinism at hand. The same principles that lead us to believe our actions are not dictated so much by our genetics as by our genetics' interplay with our environment would have some amount of disdain for this deterministic approach to Parkinson's disease.
While nicotine may prove to be a possible treatment for Parkinson's, physicians will clearly not recommend its administration in smoked or chewed form. The chemicals peripheral to nicotine found in tobacco are much more dangerous than the drug itself, and are the leading causes of the numerous forms of cancer associated with the smoking and chewing of tobacco.
Somewhat ironically, a drug that is now prescribed for Parkinson's patients may in fact be used in time to treat smoking. Eldepryl supposedly causes the brain to release increased levels of dopamine, as well. This neurotransmitter is also what's missing when cravings hit, research says, and its lack is what causes the intense absence of well-being noted in those undergoing cravings associated with nicotine withdrawal. |
