Alcohol intake is a habit that is commonly seen in our world today as a normal practice by both adults and youths. It is also an intricate characteristic and serious alcohol use raises the exposure to alcohol use disorders. Drinking must be done within the recommended highest safe limits that have been set so that men do not take beyond 14 bottles each week and women do not take half of these drinks each work (Dick, Barr, Guy, Nasim, & Scott, 2017) . Failure to adhere to this standard can cause them to acquire alcohol-linked damages. The damages from extreme alcohol use comprise a higher risk of many health circumstances such as liver, cardiovascular and communicable diseases, cancer and neuropsychiatric illnesses. This paper is going to examine alcoholism and the genetic relation between alcoholism and addiction in African Americans as well as compare and contrast it with the case in the United States.
Several scholars have the perspective that an individual’s genetic composition relates to their environment to create his or her ultimate vulnerability to alcoholism. Additionally, ethnic disparities in freedom of alcohol usage and abuse correlate to disparities in the genes that code for specific enzymes that synthesize alcohol in the body. Mitochondrial aldehyde dehydrogenase (ALDH) and Alcohol dehydrogenase (ADH) are enzymes greatly engaged in alcohol breakdown (Ray, Mackillop, & Monti, 2010) . ADH2*3 allele, which is a variant of the gene is common in Americans with African roots and specific Native American communities.

Unique Problems that Apply to Alcoholism and Addiction in African Americans
It has been determined that alcoholism is genetic in some way. However, there is only partial information on what can be inherited, and there is no documentation on specific genes that could be included. Disparities in alcohol-metabolizing enzymes, as well as the genes that replicate them, are the best-comprehended elements that affect drinking behavior and the susceptibility to alcoholism. Alcohol is broken down majorly in the liver when two enzymes are involved simultaneously. ADH turns alcohol to ADH that consequently turns acetaldehyde to acetate. Tissues around the liver then synthesize acetate further (Agrawal, Hinrichs, Dunn, Bertelsen, Dick, Saccone, & Edenberg, 2008) . People with the gene mutation that translate to ALDH2 alternatively gather acetaldehyde within the blood cells as well as tissues after taking alcohol. Such people undergo a more vigorous reaction to taking alcohol that could include facial reddening, headaches, tremors, faintness, and vomiting. Significantly, few people in the world have two defective ALDH2 alleles (ultimately heightening their reaction to alcohol) have promoted alcoholism.
This present investigation goes beyond investigation to the ADH2*3 allele. Such a gene codes for a kind of ADH enzyme that may produce more effective or speedier alcohol breakdown (Dick et al., 2017). In the previous times, it has been determined that Africa American women that possess this gene are highly exposed to having children that have birth flaws because of alcohol utilization during pregnancy. In fact, the results of this scholar demonstrated that ADH2*3 that is linked with a negative family history of how Alcohol began (Edenberg & Foroud, 2013) . These results indicate that in this category of young African American adults that were considered for this study may be linked with a reduced exposure to being an alcoholic.
A positive family history as far as alcoholism is concerned is among the most significant and coherent indicators of an individual’s susceptibility for acquiring alcoholic disorder. People with a history of alcoholism in the family have a higher chance of demonstrating alcoholism in due time, (Ray, Mackillop, & Monti, 2010) . Therefore, a biological relative, for instance, a father or sibling that is taking a lot of alcohol as a lifestyle heightens the chances of the individual in promoting his ability to contract the disease. nonetheless, in the same way, all the genetic diseases are contracted or transferred, not all children or relatives are vulnerable to the genes that cause alcoholism, and everyone lives in various environments predisposes them further to the risk of being alcoholic (Dick et al., 2017) . The engagement between genetic disposition as well as environmental factors constantly motivate scholars to do more investigation on the matter.
There are variables that are significant triggers of alcoholism as they affect individuals psychosocially. These include religion, family unity, having a job, as well as positive peer impacts. These are categorized under protect elements. The opposite of these factors such as no religious standing, weak family ties or non-supportive parents, joblessness and negative peer pressure highly expose people to alcoholism. Such factors such as genes can be different slightly as it regards to ethnic backgrounds (Agrawal et al., 2008) . For example, acculturation pressure is considered to affect drinking in Hispanic second-generation teenagers and not African Americans. Among African Americans, religion is one fundamental element. Nonetheless, much evidence has confirmed that it is more just faking religion, but instead, being committed to these religious services that influence someone’s overall perception of alcohol (Mbarek, Milaneschi, Fedko, Hottenga, de Moor, Jansen, & Penninx, 2015) . Religious conventions are aggressive at encouraging people to abstain from taking alcohol, which makes people be destructive instead of contributing to their families and society (Samochowiec et al., 2008) . Therefore, keeping away from variables that trigger the African-Americans to have the tendency to be addicted to alcohol should be highly avoided.
Since alcohol synthesis in the body can substantially affect drinking pattern and the susceptible of people to alcoholism, it is significant to recognize the influence of genetic elements on metabolic processes that occur on the alcohol. Various genes, each of which may exist in varying situations, prearrange the various ADH and ALDH forms (Ray, Mackillop, & Monti, 2010). Scholars have determined variations through ethnic groups in the rates with which every person’s genes or gene variations happen. More studies are urged in the future to make a comparison between the presence of high-metabolism of ADH2*3 allele between African American alcohols as well as those that do not take alcohol at all (Edenberg & Foroud, 2013) . It can be forecasted that the rate of ADH2*3 will be reduced in the alcoholics than in those that do not take alcohol.
Several studies on genetic relationship have confirmed a pharmacogenetic impact of missense variations in genes in the alcohol breakdown path. This is particularly true for alcohol dehydrogenase 1B (ADHIB) and ALDH2 that affects lifetime recommendations and actions like the vulnerability of the offspring to alcohol dependence. Even though these variations play a significant role in defining individual stages of alcohol abuse, they elaborate that a small percentage of the genetic influence on alcohol use. The findings of Edenberg and Foroud (2013) suggest that there are particular genetic factors that could be explored in large or ethnically different populations, utilizing genotyping avenues to enhance genome-wide exposure. To deal with this aspect, Agrawal and other researchers (2008) came up with a genome-wide study on alcohol communication among African American population. It has been formally recognized that such studies present efficient and productive results by the researchers consider questionnaire data that are in large cohorts that enables them to elucidate the genetic foundation of alcohol-related elements.
A study done on mothers and children of African American origin reveal that existence of the ADH1B*3 allele in mothers may bring down vulnerability infant impairment induced by alcohol. Agrawal and other scholars (2008) suggested that among African-American women that took averagely one drink each day, those that have ADH1B*3 were less exposed than those that did not have the allele so that their infants could not easily contract elements of fetal alcohol spectrum disorder (Ray, Mackillop, & Monti, 2010) . The outcomes suggest that intensified alcohol removal frequency in individuals with the ADH1B*3 allele has a protecting influence against alcohol-motivated development changes, indicating that, for a shorter moment, the infant is likely to be affected by any alcohol that the mother had taken.
In other studies that involved 246 African-American mother-infant duos, assessing the mothers ADH1B standing and alcohol consumption during the moment they are pregnant as well as how the infants are doing on tests of their mental development when they are one year of age (Samochowiec et al., 2008; Ray, Mackillop, & Monti, 2010) . The study determined that African-American women with the ADH1B*3 allele were less susceptible to bearing infants that had alcohol-associated birth defects than women that did not possess the allele. The study confirms that ADH1B*3 allele may be linked with more effective alcohol metabolism even at extreme blood alcohol rates (Agrawal et al., 2008) . Furthermore, the research suggested that these findings supported the hypothesis that alcohol instead of acetaldehyde induced fetal defects. Consequently, these findings also support that a particular genetic disposition (that is existence or absence of the ADH1B*3 allele) affects the vulnerability to alcohol-associated defects. Therefore, African Americans pregnant women should just seize from taking alcohols even after their delivery, as that affects the infants directly.
Alcoholism and Addiction in African Americans and the entire U.S Population
The US Census Bureau indicated that as of July 1, 2017, about 13 percent of the Americans are African America (Kohnke, 2008). The Africa Americans are seriously struggling with alcohol consumption and other substance abuse at a higher rate than any other ethnic community in the USA. Extreme alcohol intake is also an avoidable risk factor for several injuries as well as accidents. In sum, extreme intake of alcohol led to about 3.3 million deaths that occur yearly globally (or 5.9 percent of all deaths) as well as 9.8 percent of all fatalities in the United States (Edenberg & Foroud, 2013) .
About 43.5 percent of African American adults that are 12 years and more, that currently hooked to alcohol consumption as at 2013. 7.4 percent were really thrashed with alcohol addiction. Twenty percent of the African Americans are indulging in binge drinking according to the 2014 national survey, which is slightly below the national average of 24 percent (Edenberg & Foroud, 2013). A few African American teenagers record underage alcohol consumption than the nation average. In 2014, about 8.5 percent of African American youths between the ages 12 and 21 indicated drinking alcohol in the previous month related to a national average of 13.7 at that time.
Many kinds of ADH are founded on their structural resemblances and can be characterized into several other classes. There is a class I ADH enzymes, for instance, that comprise ADH1A, ADH1B, and ADH1C that are recognized to be the most significant as far as alcohol metabolism in people is concerned. The genes encoding the first class of ADH enzymes have been called ADH1A, ADH1B, and ADH1C (Ray, Mackillop, & Monti, 2010) . For a number of these genes, many other alleles have been uncovered, especially for the ADH1B gene. For the gene, three major alleles exist namely ADH1A*1, ADH1B*2 and ADH1C*3 that are very critical in influencing many changes in alcohol synthesis. The ADH1B*3 allele is present in about 15 to 25 percent of African Americans (Mbarek et al., 2015) . In another study of 98 African Americans, 32 percent had at least one ADH1B*3 allele and 2 percent had two ADH1B*3 alleles (Dick et al., 2017).
The occurrence of the alleles depends on different ethnic backgrounds to which people belong. ADH1B*1, for instance, is the most renowned allele and is found in different frequencies in all people in the United States (Dick et al., 2017). The ADH1B*2 allele exists in many of Far East Asians and a few Caucasians, Jewish people, as well as among African Americans in the USA. Lastly, ADH1B*3 has also been determined among the people of African background and certain groups of Native Americans (Samochowiec et al., 2008) .
Best Treatment Practices for Specific Issues Relevant to African American s
African Americans with at least one ADH1B*3 allele were importantly less vulnerable to possessing a family history of abuse of alcohol than those that did not possess the allele. Since the family history of using alcohol was one the most proper indicators of alcohol abuse and reliance, the researchers determined that the ADH1B*3 allele may be linked with a reduced risk for alcohol use (Agrawal et al., 2008) . This determination is backed up by other fresh studies that also concluded that ADH1B*3 allele was importantly linked with a lesser vulnerability for alcohol dependence among African American population. Therefore, a lot of research has been done to trace the presence of the ADH1B*3 allele in the African American community and maximize it as it helps in the breakdown of alcohol consumed in their bodies. From this, a remedy can be through family support, in cases where some members are free from alcoholism. The support is needed especially during withdrawal from alcoholism. Most of African American families believe in the power of family, which has been a solution to most problems over a long time.
Metabolism of alcohol is among the biological factors, which affect drinking behaviors, creation of alcohol addiction and alcohol-motivated organ destruction. Edenberg and Foroud (2013) reiterated that oxidative alcohol synthesis relies aldehyde dehydrogenase (ALDH) and alcohol dehydrogenase (ADH). ADH has the function of changing alcohol to extremely harmful metabolite acetaldehyde, which is broken down by ALDH to acetate and ultimately to water and carbon (IV) oxide. For both ADH and ALDH, many determinants are present that vary in their potential to synthesize alcohol and acetaldehyde, respectively (Samochowiec, Kucharska-Mazur, Grzywacz, Pelka-Wysiecka, Mak, Samochowiec, & Bienkowski, 2008). For instance, some ADH variants are specifically active and increasingly synthesize to alcohol and to acetaldehyde gradually. In both of these instances, acetaldehyde will amass after alcohol has been consumed, causing its toxic impacts on the user. For example, it will be resulting in a flushing syndrome that has characteristics like facial flushing, vomit as well as a heightened heartbeat. Such impacts prevent African Americans from alcohol use and thus protecting them from the influence of alcohol abuse.
The framework under which existence of some alleles influences an individual’s drinking habit is uncertain. Nonetheless, research has confirmed that expectations of impacts of consumption of alcohol are linked to drinking practice in teenagers and grownups. Not much is recognized concerning alcohol outlooks in African Americans, but a study by Edenberg and Foroud (2013) determined the link between alcohol-associated expectations and the existence of the ADH1B*3 allele in 68 African Americans. The alcohol related expectations assessed in the study evaluated encouraging personal views, emotions, and practices that are linked to alcohol abuse, like increased sexual involvement, physical and social pleasure, and enhanced assertiveness (Samochowiec et al., 2008) . The scholars resolved that existence of the ADH1B*3 allele may be linked to a less satisfying subjective reaction to alcohol intake, a consequence that has been linked with being secured from alcohol consumption disorder development in other people. The young persons should also be provided with avenues where they can release their aggression as well as find alternative programs where they cannot think of alcohol consumption or involvement in deviant activities. The African American youths resolve to consume alcohol as a peer pressure or the grounds of being idle. Therefore, appropriate programs and activities are significant to keep them at bay from alcohol and substance abuse.
Additionally to the polymorphisms deliberated above, the study has also determined significant connections between the likelihood of alcoholism and specific ALDH (ALDH1 and ALDH2) polymorphisms in African Americans. ALDH1 has been linked to a lot of alcohol addiction, alcohol-related flushing, and alcohol sensitivity (Mbarek et al., 2015) . A study by Edenberg and Foroud in 2013 that dealt with several ethnic groups, including African Americans, identified a low rate of the ALDH1A1*2 allele in many of these groups. However, ADH1A1*3 allele was identified only in African Americans. Furthermore, the outcomes of the study indicated that the ALDH1A1*2 and ALDH1A1*3 alleles may be linked with a lessened risk of alcohol addiction (Samochowiec et al., 2008) . Thus, treatment programs on alcohol abuse is significant to handle those African Americans that have been affect by consumption of the drugs. However, there is no much risks of transferring addiction to the fetus because of the ADH1A1*3 allele that is dominant in their bodies. A unique need should be put in the treatment of African Americans struggling with alcoholism. Most of them should be encouraged to consider religion and in some cases spirituality as a remedy for treatment of alcoholism.
Conclusion
Many ALDH and ADH alleles, in most cases, are majorly or solely associated with African Americans. They happen to give some kind of defense from the susceptibility to alcohol addiction. For instance, the ADH1B*3 allele that has been determined in about 24 percent of African-American people, which amounts to an upper frequency of alcohol breakdown, was linked to a decreased susceptibility of family history of alcohol addiction, less positive reaction to alcohol, as well as protection against alcohol-associated defects. In the same manner, the ADH1A*3 allele that has been found solely in African of American origin also may be linked with a decreased likelihood of alcohol addiction and abuse. Together, the result of this study will enhance our grasp of the relative vulnerabilities of African Americans to alcohol consumption and addiction as well as the health consequences related to these and suggest solutions to them.
