The Effects Of Excessive Alcohol Use On Substance Abuse

Good Essays
Alcohol may seem to be very innocent to people and a way to socialize with others even though that at times can be true it can also be very harmful and in some cases dangerous. Studies show that impulsivity has long been considered a risk factor for harmful alcohol use. Advances in neurocognitive models of impulse control have allowed substance abuse researchers to understand how dysfunction of specific cognitive mechanisms underlying behavioral control can contribute to substance use (Fillmore, 2003; Jentsch & Taylor, 1999;Lyvers,2000). Intoxicated drinkers may find their ability to inhibit behavioral impulses compromised to a greater extent than their ability to activate responses (Fillmore, 2003). As a result, as drinkers consume alcohol and become more intoxicated, they become less able to inhibit further alcohol consumption. For example, one study (Turrisi, Wiersma & Hughes, 2000) found that positive expectancies were associated with a higher advantage to experience blackouts, hangovers, and fights, even when drinking was statistically controlled for. From personal experience I have family and friends who after having consumed alcohol would get very aggressive and sometimes violent. With regard to negative alcohol expectancies, Borders, Barn- well, and Earleywine (2007) found that individuals expecting alcohol to increase aggression were more likely to report aggressive acts and hostile feelings after drinking, independent of the amount of alcohol consumed.

    When someone is already depressed, it can be very easy to fall into the destructive cycle of alcoholism. Additionally alcohol can also cause mental disorders. “Frequently either the perpetrator, the victim or both have been using alcohol heavily. According to the National Woman Abuse Prevention Project, some abusers rely on substance use (and abuse) as an excuse for becoming violent” (“Excessive Alcohol”). It is easy to understand how alcohol can cause people to make decisions that are not “their choice”.…

    The brain is still developing at younger ages and may cause damage to itself as well as neurocognitive deficits and other physical symptoms (Zeigler et al., 2005) Not only does binge drinking during development harm the brain more than older age groups, but is also hinders the ability to store and develop memory. This sort of trauma can be inflicted among adults as well, but children with developing brains are more susceptible to this sort of damage (Zeigler et al., 2005). Many valid theories attempt to answer why the underage are drinking more at younger ages, but by removing the sinful stigma of consumption, drinking rates may lower significantly at all illegal ages. Michael O. Leavitt, in a message from the U.S. Department of Health and Human Services, best summarized the growing problem present day’s society faces: “Learned early, the lessons of good health will last a lifetime.…

    While alcohol may allow for a temporary relief from anxiety, depression, and overwhelming feelings and stressful situation, it is not a smart choice in the greater capacity of mental health. Alcohol consumption causes the user to lose the ability to exercise smart decisions. Even when a person is not under the influence of alcohol, it still weakens their ability to use common sense in some instance due to the long-term effect of alcohol consumption, therefore affecting their mental power and ability to act within due bounds. Drinking alcohol overhauls brain processes such as memories and acquiring distinct information (Viner). When the brain loses the ability to focus on positive astute of personal references, less personal bounds are put in place instead.…

    When this becomes an ongoing problem, and the person is drinking excessively over an extensive period of time, people may finally start to take the behavior more seriously and see the problem with it. Without the excessive behavior though, alcohol is the most widely socially acceptable substance for someone to use to self-medicate. It interacts with the neurons in the brain involving the neurotransmitters GABA and Glutamate. GABA acts an inhibitor to neurons firing when it binds with its receptor and Glutamate acts as an excitatory neurotransmitter. Alcohol is an enhancer in that it makes GABA more of an inhibitor than it already is and blocks glutamate from binding and creating an excitatory response in the neuron.…

    They think it will solve the problem of underage drinking. It will actually do quite the opposite. The U.S.A should not lower the minimum drinking age because it poses too many dangers for youth. The danger of youth drinking can affect many areas of the brain and could put other in danger other than the participant. Megan McMurry, a clinical psychology intern at UBA notes, “Drinking alcohol in excess is dangerous and can quite easily lead to death.” Binge drinking, which is when a person drinks five or six…

    Being addicted to the consumption of alcohol liquor is known as alcoholism. Alcoholism is classified as both a mental and physical disease. Abusing the substance is self-determinant at first but over time becomes a habit, causing the person to lose control of how much to consume, thus becoming an alcoholic. Even though the cause of alcoholism is still unknown, it is known that dependency happens when you drink so much that chemical changes in the brain occur. These chemical changes in the brain increase the pleasurable feelings you get when you drink alcohol, which makes you want to drink more and more.…
