The nervous system is the control system and the network of communication for the body. All of our thoughts, and behavior can be traced to the activity of a neuron. A typical neuron has three important parts: first a cell body, second dendrites and last an axon. All three parts are important for our daily functions. Drugs however such as Alprazolam, also known as Xanax, can alter these actions and have short and long term effects that aren't always the best feeling. The nervous system is made up of nerves, the spinal cord and the brain. The nerves control everything we do; they carry messages that tell us to move, to breathe, to feel and to think. Nerves run to the muscles, organs, heart, lungs, blood vessels, brain-even to our teeth and skin. Neurons are the specialized cells that conduct impulses through the nervous system. There are about 100 billion neurons in just the brain. A neuron has three parts that make it up, a cell body, which carries metabolic functions, dendrites being branched fibers which are the primary receivers of the impulses from other neurons, and axons that are slender tail like extensions that are the transmitting end that sprouts into many braches each ending in an axon terminal.
Xanax is a central nervous system depressant. This means it slows brain activity. Xanax works specifically by increasing GABA (Gamma-aminobutyric acid) activity, curbing the brain’s “excitability” and allowing the brain to restore its natural balance. Although different classes of central nervous system depressants work in unique ways, ultimately it is their ability to increase GABA activity that produces a drowsy or calming effect.
When taken as prescribed, the short-term effects of Xanax are beneficial to many individuals. It has the potential to reduce the physical tension, restlessness, and feelings…...

Heroin Abuse: Reaching the Suburban Youth

...Heroin Abuse: Reaching to the Suburban Youth The best driving force to get informed and motivated about a certain topic is a personal experience and my motivation came when one of my best friends passed away from a heroin overdose. Almost exactly a year ago, this friend of mine passed away from a heroin overdose and none of his close friends or family even knew the problem had escalated so greatly. It had all started with a pill addiction to xanax that slowly grew more severe but with a few interventions and a couple of trips to rehab, most of us thought that he was doing well and had kicked the habit. Little did we know that he had kicked the xanax habit only to graduate to something as intense as heroin. The frightening thing about this drug is that my friend was a small, upper class, Jewish boy from the suburbs of St. Louis and would not typically be the image you think of when a person might think of a heroin addict. He was the furthest thing from an underprivileged, poor, inner city adult. But addict hew was, and it is still somewhat of a mystery to those who were closest to him as to how he was able to access his drugs. For every person that believes they know the true meaning of the word “addiction,” there is another person right beside them to argue a different point of view. In this day and age, one would think that doctors or scientists or psychologists would have narrowed it down to a universal description but this is not the case. There are many......

Anxiety in My Life

...do that will help me avoid an anxiety attack. One thing that helps with my anxiety is eating on a regular schedule. If I can keep my blood sugar fairly level I can avoid getting into an anxious mode. When I do begin to get anxious I can sometimes stop the anxiety by going somewhere by myself for a few minutes. At work, I have to go to the bathroom for a few minutes to get some alone time. I do some deep, slow breathing and close my eyes and meditate. I call it talking myself out of a panic attack, and it works. I have tried taking medication for my anxiety, but I do not like the way it makes me feel. The doctor has prescribed anti-depressants like Zoloft and Paxil, and anti-anxiety medication like Xanax. I do not like the side effects of the anti-depressants. The Xanax does work well to calm me if I have a panic attack, but it can be addictive. I have tried various natural remedies, like vitamins, herbs and amino acids. I take B complex vitamin every day, along with extra B 6. The B vitamins have helped me as much as anything. I also have tried St. John’s Wort, but I do not seem to notice a difference when I take it. I have tried various different amino acids; the ones that I seem to help are GABA, L-Glutamine and L-Theanine. I took a test that reported what vitamins, minerals and amino acids I was deficient in. I have concentrated on the ones that help with stress and anxiety. I have been to counseling, but it does not seem to help me, in fact it seems to......

...as an anesthetic.” According to the website of Illegal Drugs, “Cocaine comes from the leaves of a cocoa plant which grows in South America and transformed into a white powder.” This particular drug can be addictive because it causes the blood vessels in the body to become narrow, constricting the flow of blood. Prescription drugs can be taken for different reasons, but can also be addictive if not taken properly.

...soon. Where Adderall acts as a cognitive performance enhancer, Xanax is society’s answer to therapy in a bottle. Xanax belongs to a group of drugs called benzodiazepines. It works by slowing down the movement of chemicals in the brain that may become unbalanced. This results in a reduction in nervous tension such as anxiety, panic disorders, and anxiety caused by depression. Today, Xanax is the most prescribed mental health drug in the country, totaling 46.3 million prescriptions in 2010. While many individuals take Xanax to deal with issues of nervous tension, others are simply abusing this drug and using its chemical properties to achieve an escape from reality. Many think of Xanax as the hors d'oeuvre for the middle-aged housewife’s glass of red wine, however, this drug has become increasingly popular amongst teenagers and young adults. At its most innocent stage of non-prescription use, young people will take this drug as a means of finally getting sleep, particularly after a long day on Adderall or to calm their nerves from increased anxiety. However, more and more, Xanax is used in social settings as a party drug. The National Institute on Drug Abuse released a study stating that “the most dramatic increase in new users of prescription drugs for nonmedical purposes” occurred amongst teens. Xanax not only fits this mold; it has shaped it in recent years. Author David Amsden eloquently explained how Xanax fits in the social setting of today’s young people, “It is......

Other medication effects Being in the trucking industry, my drivers cannot under any circumstances use marijuana because the FEDs have not approved it as a medicine, it is still a controlled substance in their eyes. I have one driver who has anxiety, she has to take pills for it. These particular pills, your body becomes dependent on and you can’t just stop taking it. Your body will have withdrawn symptoms. So why would we want our truckers driving all over the country using pills instead of a natural plant? Truckers are allowed to take Xanax for their anxiety, Xanax is a very addictive pill also, and it also is a very strong pill that causes you to black out, forget things, and just pass out, fall asleep. I tried Xanax for my anxiety and it was not something I could use and function in a normal day. I am not okay with my drivers using pills instead of marijuana. I have another driver who has a bad hip, she is getting a whole hip replacement soon. This driver is not even allowed to use CBD lotion on her hip that does not even get her high.

...It all began right after I checked in for my flight, I walked towards the gates and was about to enter the line. I was ready to go through the security screening and suddenly my anxiety crept up on my out of nowhere; “Are they going to strip-search me?”. My hands began to shake, “I couldn’t risk it.”, I thought to myself. I quickly popped the xanax pill in my mouth that my roommate gave me and got in line. You see, I’m absolutely terrified of flying. Have you ever been through turbulence? It’s no joke! My roommate was aware of my fear of flying, so he kindly offered me a xanax pill to help calm me during the flight. He told me, I would “blackout” and then I would be fine. But suddenly it hit me that maybe I couldn’t take it in through security and that's when the anxiety hit me. As walked closer towards the gate, I couldn’t help but notice all the security guards; were they looking at me? It felt like they were giving me the mean mug and I began to ask myself, “Why are they looking at me?”. Then I began to get paranoid -I forgot to mention that I ate a weed brownie an hour before all this and it was in full-effect. Now I was truly beginning to freak out! I am not sure how I managed to keep it together, but I finally got to front and put my bags on the belt for screening. I walked through the metal detector, but quickly noticed my bags didn’t. The officer told me there was a “red flag” and they needed to go through my bags. My face quickly became as pale as a ghost,......

Generalized Anxiety Disorder

...which is mostly about unimportant things. Also, other symptoms may include shortness of breath, dry mouth, nausea, and muscle tension. More importantly, heart palpitation is a sign to recognize. Neurotransmitters Involved and their Relationship to Signs and Symptoms Since the brain reacts directly to neurotransmitter which is small chemicals inside the body that transmit messages to the brain resulting in many neurotransmitters being related to anxiety disorders. Therefore, according to Dr. Julie Graves (2015), these neurotransmitters include gamma-aminobutyric acid (GABA), serotonin, and Norepinephrine. The neurotransmitter GABA is the target for medications used to alleviate short-term signs of anxiety. Medication such as Valium, Xanax, and Ativan are usually prescribed to intensify the calming effect that GABA has in the brain. Serotonin plays a significant role in anxiety. It is believed that the drug buspirone helps reduce anxiety by increasing serotonin activity in the brain. Therefore, a natural level of serotonin improves a person’s well-being. The last neurotransmitter is Norepinephrine. Norepinephrine is closely related to the drug epinephrine, commonly known as adrenaline. Stress is mostly linked to high adrenalin levels as well as being in the constant state of fear is comparable to anxiety. The Diagnosis To diagnose generalized anxiety disorders a health care provider usually performs a physical exam to check for signs that the stress may be......
