Nicotine: The Saint and The Devil
Nicotine is one of the many drugs
that has a high dependence on the addiction and reliance of its users. Analogous
to a countless number of drugs, the affects of Nicotine can both help to
deteriorate and, surprisingly in this case, protect one’s health. Although the
involvement of Nicotine with a myriad of illnesses that smoking tobacco and
cigarettes usher, there is no denying its influence in the brain, specifically
in the exclusive nicotinic receptors and reward system. Cigarette smoking still
remains as the centerpiece of anti-drug agencies. With the dependence on the
world-spread drug continuing steadily, researchers remain steadfast in their
search for the positive and negatives effects on the brain that the drug
entails.
The association of Nicotine with
one of the larger leading causes of death validates its complexity and ability
to stimulate the user’s mind. Research conducted by Dr. Paul Newhouse of
Vanderbilt University’s Center for Cognitive Medicine sets out to prove that
Nicotine has many beneficial aspects as well. Previous research already
concludes that Nicotine is coupled with the area involved with acetylcholine, used
for retention and cognitive intellect. Dr. Paul tested patients with Mild
Cognitive Impairment (MCI), which is a common antecedent of Alzheimer’s
Disease. Collecting data from 74 non-smoking adults that suffer from MCI, half
were given Nicotine patches to be used daily and the other half placebo
patches. After roughly half a calendar year, the data collected showed
substantial increases in memory development and alertness with those that used
the Nicotine patches. Perhaps one of the possibly surprising outcomes was the
lack of withdrawal or dangerous side effects in the users. Nicotine can be safe
drug, and is administered over the counter. Providing Nicotine treatment for
disorders like schizophrenia, down syndrome, Alzheimer’s disease is a
developing field, and it seems that the drug itself works at its highest
capacity when there are already preexisting complications. It has often been
assumed that people that suffer from health issues can self-prescribe his or
herself with smoking to allow their mind to function properly. It is true that
the population that suffers from Parkinson’s or Alzheimer’s is historically
more dense with smokers. This leads one to wonder if said patients can
attribute their addiction to this increase in capability or for other reasons
like repeated reward.
Many times, addiction is offset by
a reward of some sort. If one is harming themselves during this process, it can
be assumed that that reward is thought to be in his or her better interest
moving forward. This Is due, in part, to the compensation factors that are
associated with the drug. If heroin users didn’t experience a spontaneous
stream of euphoria, the ability to refuse it should be much easier. In
“Nicotine Potentiation of Excitatory Inputs to Ventral Tegmental Area Dopamine
Neurons”, Dr. Dan McGehee tackles the exact areas that nicotine confronts in
the brain. Subjecting a section of rat Vetral Tegmental Area (VTA) cells to the
smoke of a cigarette, testing the response of neurons associated with
neurotransmitter dopamine. Similar effects are seen in cocaine and other
various amphetamine. Nicotine stimulates these reward-based neurons in the nucleus
accumbens, rewarding the user with a rush much smaller in magnitude to that of
heroine. Even so, the incredibly small euphoria of Nicotine may not play the
largest role in the addiction though. Often times, the process and action of
smoking coupled with the activities associated with it are what illicit this
craving. A user can tell you first-hand of his or her routine of fetching their
pack, going outside, taking their cigarette and finally receiving that mental
break. Nicotine is a complex drug, and its ability to enhance the user for a
long period of time with such little amounts makes it highly usable. As Dr.
McGehee puts it, “It would be difficult to design a better drug to promote
addiction”.
As research continues to be
published on the many positive effects of Nicotine, it is only natural for one
to question its part in the addiction to smoking. For those that already suffer
from a shortcoming such as Parkinson’s, Alzheimer’s Disease, or Schizophrenia,
it can work to improve long-lasting damage in memory and learning. What makes
it highly dangerous is its ability to trigger the excitation of dopamine
neurons, allowing the user to experience a low-grade rush long-lasting
neurotransmitter effects. Even with the general decrease in cigarette smoking
across the world, the several ways one can be drawn to Nicotine allows it to
join an exclusive club of drugs that are done and abused almost in ubiquity. Depending
on the user’s physical and mental state, Nicotine has a variety of neurological
effects that seemingly ease the consumer’s mind. Even with its positive
effects, the orchestrated release of dopamine, also in cocaine, can work
against the mind in many ways in the long-term. Although the addiction of this
infamous drug can be attributed to all of the affects above, there are many
factors outside of the Nicotine itself that draw somebody back to their next
dosage. Whether it is the desire for your next little rush or the longing for
an allotment of time where your brain can function more properly, Nicotine provides
the user with a luxury car with minimal gas.
