Genetic And Environmental Causes Of Addiction

The concept that drugs abuse and being more likely to inherit the likelyhood of being addicted has always intrigued me. It intrigues me because it makes sense. Why is it that people pick up smoking cigarettes after the first time? Or people of Native American descent are more likely than most ethnic groups to be alcoholics? There is the whole concept of nature v. Nurture. Our surrounding pre-determine our likelylihood of becoming addicted based on if one of our parents drank. But what if it's more than that? What if what we are inheriting is not the behavior immersed around us, although that does play a factor, but the genetics behind the initial addiction?

Psychology is a developing science which studies the mental functions, processes, and behaviors of an individual. In the science of psychology, many debates arise; nature vs. nurture is one of the most popular ones. These psychological debates are followed by research, backing up either nature or nurture or both. Nature suggest heredity impacts human psychological development; nurture suggests the environment impacts our psychological development. Addiction plays a large role in nature vs. nurture. Addiction is defined as a person being attached to a certain activity or item; an addict is one who has a dependency on particular substances or activity. There are many debates on whether addiction is caused by genes or the environment. Many researchers believe if they had the answer of addiction being a genetic condition or an environmental factor, they would be able to resolve the problem of addicts, or so they believe.

According to the American Society of Addiction Medicine, genetics account for over fifty percent of addiction disorders. Elders having a past with drugs, the addict

Addiction is thought of a biological nature that is past through genetics according to the biological theory as explained in P2. A contrasting theory of the biological theory would be the classical and operant conditioning theory, this was made by Pavlov. The basis of conditioning theories is that addiction is the end result of the reinforcement of drug use. The drug acts as a reinforcer and gains control over the user’s behavior. In contrast to the biological models of the exposure theories, these conditioning models suggest that anyone can show addictive behavior if they are given reinforcements, regardless of their genetics. The advantage of this

There are many models and theories which attempt to explain the causes of substance misuse and dependence. They range from those which highlight the importance of genetic and biological factors to those which stress social and psychological factors and those which may consider the ‘blame’ to be that of the dependent individual (Rassool 2009).

“The statistical associations between genetic factors and alcohol abuse are very strong” (McNeece & DiNitto, 2012). However, there is still much debate over the validity of genetics as a definite cause for addiction. Perhaps, the reason for this is because the number of children of alcoholics that go on to become alcoholics is still small. Additionally, genetic predisposition cannot explain the number of cases of alcoholics that did not come from alcoholic parents or families. In fact, addiction can be so prominent, that it remains even after the drug use has ended (McNeece & DiNitto, 2012). Therefore, the biological theory should not be ruled as it is based on what takes place in the body. There is no other theory that can explain how a person could still have addiction symptoms when the substance is absent from their system. Predisposition implies that there is a mutation or malfunction in the body that appears to cause a craving or susceptibility to becoming addicted to a substance.

Although the collection of findings from several types of genetically informative research designs does provide compelling evidence for the influence of genetics and heritability on the risk for addiction, they do

Chemical addiction has been impacted by both genetic and environmental risk factors (Eitan, Jaradat, Hulse, Tay, 2012). To make a better understanding of the process leading to addiction, one must determine genetic factors (Eitan et al., 2012). Chemical addiction is the result of the interaction of many genes related to the central nervous system (Eitan et al., 2012). According to Kovac, chemical addiction is viewed as a matter of collaboration of the environment, society, neurological and chemical mechanisms simultaneously working together in order to form behaviors extremely resistant to change.

Biology and genetics influence substance abuse and addiction. According to Prescott, Madden, and Stallings, (2006), a number of obstacles confront researchers considering genetic influences on substance-related behavior. Preliminary there is a significant discrepancy across civilizations and archival periods in the prevalence and classifications of substance use (i.e., cocaine, alcohol, tobacco, cocaine, or heroin). A person’s biology is a determination in the addiction of risk. For example, Prescott, Madden, and Stallings (2006) assert many studies indicate increased rates of alcoholism among adopted males; although he is not influenced by his own biological parents (p. 475; see Cadoret et al. 1985; see Cloninger et al. 1981). It has been suggested that twins (e.g., adults) are most likely to inherit smoking dependence. Various studies throughout countries study variables (e.g., age and gender) according to Prescott, Madden, and Stallings (2006).

79). Overall, this is a problem, because there continues to be a lack of the public endorsement and support of those seeking treatment regardless of the addiction. Individuals suffer with addictive behaviors for many reasons that include genetic factors. These things are uncontrollable and are harder to be prevented. Inaba and Cohen (2014) stated, “One of the genes that signals a susceptibility to compulsive overreaction” (p. 7.47). The new definition of addiction non/substance and behavior is now based on the psychoactive drugs and certain behaviors that produce the surge of dopamine in the midbrain are biological substrate for addictive behavior (Smith, 2012). Overall, it is important to include all addictive behaviors and substance abuse when diagnosing individuals. It is more important to treat all conditions or addictions than it is to assume that it is not as an important or one is more problematic than one or the

In order to fully understand addiction, one must examine the pathways and circuits in the brain as well as the genetic attributions that form this type of behavior. It is important to note that addiction has various forms such as with substances (alcohol, tobacco, drugs) and behavioral addictions (food, sex, shopping). With the forms listed and the many other types of addiction that are out there, they all contribute to alterations in brain structure and function. This article focuses on a particular addiction- cocaine addiction- and how it impacts gene expression and neuronal function. Like other substances of abuse, cocaine users have behaviors that cause them to compulsively take the drug with a loss of control in amount. Even with

The disease model: This theory states that an individual who abuses drugs requires medical treatment rather than moral punishment or exhortation. This theory also justifies spending money to research substance abuse in the same way that money is spent to research other diseases. However, usually the term disease is reserved for a state in which we can identify an abnormal biochemical or physical condition. No abnormal biochemical or physical condition has been found in the case of substance addiction, although mounting evidence suggests that some individuals are genetically predisposed to addiction more so than others. Nevertheless, this theory continues to appeal to researchers, and an intensive effort is always being made to identify the physiological “switch” that establishes addiction after exposure to a drug (Lee, 2010).

They assume addicts lack moral principles or self-discipline and that they can quit by simply deciding to. The reality is, people who have struggled with substance abuse have often found it extremely difficult to quit due to the physical and/or mental addiction. Drug have the ability to change the brain patterns and cause health complications, making things harder in the long-term and may determine life or death. Fortunately, because of more research, there are more ways to back out of an addiction and seek help through an enduring and extensive treatment. Factors that affect the likelihood and speed of developing an addiction are environmental and individual factors, including genetics and

When a mother brings her young son along with her to a methadone clinic for her daily dose, each nurse and staff members looks upon the little boy with worry. Is this child in risk of falling into the same patterns simply because his mother will find it difficult to teach him differently? Or, is he predisposed to drug dependence due to his own DNA? While drug dependency has not yet been reduced to a few "undesirable" genes in the human genome, most, if not all, scientists will agree that the risk of drug dependence is largely heritable. Why does drug dependency depend on genetics, and are there environmental factors as well?

When someone says, “You get that laugh or that smile from your father or your mother.” You don’t always believe them, but in some studies today it is said that if your parents or anyone in your family has a history of a drug addiction those traits in their genes have a decent chance of being passed down to the children causing problems for them later in life. According to the Drugs and Addiction article in the 2009 Addiction Journal, “Family, twin and adoption studies suggest that the heritability of substance use disorders is moderate to
