Furthermore, this also affects their families as it tends to put relationships at risk due to the behavioral problems posed by those with drug problems. It is important to identify that drug addiction is one of the major factors contributing to job losses as it affects people's performance and their ability to fully perform daily tasks as such individuals lose control of their behaviors. Although the costs associated with purchasing drugs may be high, this does not hinder individuals' access to these drugs, further increasing their consumption. Say no to plagiarism.

Get an original essay An individual's tendency or inability to restrain himself due to access to medications poses a serious threat to one's health and relationships with others. Cases of relapse are often evident that make drug use difficult to manage, which increases the importance of the biological approach to addiction. Even though individuals are aware of the dangers that drugs pose to the human brain, they are unable to adopt the new mechanism to resist such drugs as the brain activity is highly impaired. As a result, the functioning of the therapeutic process is greatly impaired due to the inability of personalities to respond to changes that in a certain sense can influence the functioning of the brain. The main challenge in drug addiction is developing an understanding related to addiction and neurobiology and examining individuals' relationships. This helps ensure that a person's mind is able to respond to the urge to take the drug by creating a resistance in the human brain. The addiction process in relation to biology makes it difficult for the brain to reject the urge to take drugs, especially during the therapeutic process and the need to eliminate cases of relapse. Human BrainThe three parts that are often affected by drug addiction or abuse include the brainstem, the limbic system, and the cortex which has different roles. Brain functions such as sleep, breathing and heart rate are normally regulated by the functioning of the brainstem. On the other hand, decision making, the ability to identify and solve problems, the planning process, thinking, tasting, hearing, touching and even the ability to see are normally managed by the cerebral cortex. The responsible part of the reward system is the limbic system (Kalant, 2010). Therefore, the tendency of individuals to feel satisfied is regulated by this part and this, however, helps the person to ensure that duplication of activities occurs as it helps individuals to survive. As a result, other activities ranging from the ability to interact with others to eating come from the limbic system. However, the system is also susceptible to cases of drug abuse. Furthermore, drug addiction affects the limbic system thus regulating the emotions of individuals. Nerve cells or neurons determine the actions of the human brain as they transmit information from one part to another. Drug Addiction Drug addiction normally affects the brain communication process by altering thefunctioning of neurons in the brain. As a result, the normal communication process is disrupted, making it difficult for a person to respond to the reward system. Furthermore, neurotransmitters are vital in communication and the ability of most drugs to mimic the system helps trigger the communication process even if negative messages are conveyed in this case. Neurotransmitters in the brain (dopamine) can be released in higher qualities especially with increased consumption of drugs which affect the normal switching process as their overall flow is limited. Drug addiction results from contamination of the brain's reward system or the limbic system that controls a person's ability to respond to various activities. The reward system allows a person to access the benefits and risks before engaging in certain activities. As a result of drug addiction, the user is unable to respond to the negative impact that the drug has as the system has the ability to trigger aspects of the feeling of pleasure and consequently motivate people to continue with drug use . Therefore, by changing the brain reward system, the human brain is unable to respond to the urge to take drugs even with the knowledge that such carpets will have a negative impact on people's lives (Caulkins, Reuter, & Coulson, 2011). Constant use of drugs often activates the limbic system which causes the individuals brain system to register that such actions are necessary. The reward system in the human brain helps a person make necessary adjustments as it provides the brain with information that the activities a person engages in are necessary if he or she is to succeed or survive. Therefore, the addiction process creates a scenario where the brain motivates a person to continue using drugs because the brain is unable to identify the risks and benefits of such actions. Since the brain's reward system is also activated by drinks and then food. which helps individuals respond to cases of hunger and thirst, the same process is triggered with the constant use of drugs. Drug addiction alters the brain process by creating a situation where dopamine is produced in excess or creates a situation where it is able to mimic the activities of dopamine. Although aspects such as willpower and good intentions in dealing with addiction are significant, there is always a need to structure another approach in order to prevent scenarios in which the insights that can be achieved could fall in the long run. with the use of the biological basis. Furthermore, addiction alters the human brain which is a biological process (Kalat, 2007). In the initial stage, people often have the idea that drug taking is a social and moral problem, which is true, but in the case of addiction they have less control over their actions. According to Carter and de Lecea (2011) the functioning of the brain is greatly affected by addiction which makes it difficult to reverse those changes which strongly contribute to cases of relapse every time this happens. Therefore, individuals with addiction problems often face an uphill battle to overcome these challenges considering that they are especially prone when exposed to drugs and alcohol. Additionally, there are various elements that can contribute to triggering relapses which may include the type of environment the person is exposed to. The brain controls every aspect of the human body and the ability people have to interact with others, including the relationships they are able to create with their families. Plus, other aspects like bonding, nutrition, and exercisephysical, which contribute most to the health of individuals, are largely affected by the destruction of the brain as a result of the addiction process (Cooper, Bloom, & Roth, 2003). it also helps trigger responses related to its ability to create warnings for individuals and as a result, the ability to use self-control is an important part of its success and this is influenced by the brain's inability to trigger those responses in cases of dependence. The brain process is largely affected by the increase. As a result, the use of drugs and thus the personal mechanism and ability to protect individuals from external influences are greatly hindered. The inability to control one's actions can cause mental health problems, and in some cases, this can be fatal. Brain Process The brain is an integral part of the human brain and largely determines the conduct of individuals. A healthy brain has a protective mechanism that helps provide the necessary guidance to individuals in decision making (Witten et al, 2011). Therefore, it is always necessary to ensure that the brain process is working in the right way to help ensure that people's decision making is not influenced and at the same time control individual emotions, which is vital to safeguard relationships. Parts of the brain such as the prefrontal cortex act as protection for individuals and its condition is vital for individuals' behavior and avoiding substances such as drugs and alcohol. People are often aware of the repercussions associated with taking medications, but it is the functioning of their brains that determines whether they are able to respond to such changes (Kandel, Schwartz, & Jessell, 2000). The functioning of the brain also relies on the limbic system which is responsible for regulating the brain in order to aid in behavioral adjustments and decision making that help individuals avoid dangers to which they may be exposed. Furthermore, the effect of dopamineDopamineDopamine has a significant role in the human brain due to its role in brain signaling and communication with various parts of the brain. Therefore, an increase in dopamine levels in the human brain complicates learning processes as it sends conflicting signals that further influence the learning process. As it forms the main core of the communication process, dopamine is responsible for transmitting messages to various parts of the brain to trigger anti-drug responses that can help avoid cases of relapse. In the human being there is a biological mechanism body that helps to minimize the excessive production of dopamine by relying on the dopamine receptors in the human brain. However, the functioning of dopamine receptors depends on their ability to regulate dopamine in the human brain (van Amsterdam, Opperhuizen, Koeter, & van den Brink, 2010). It is mainly about the brain's ability to make sure that the neurons are free from excess dopamine as it largely influences the brain communication process. However, poor communication within the brain makes it difficult to receive or send the appropriate signals that help control the brain. cases of relapses. The brain's plasticity determines its success in terms of modifying the various behaviors represented by the brain in response to drug addiction. The main challenge, however, is the inability of dopamine receptors to function in cases of drug addiction. The process makes it difficult to control the communication process. However, drug addiction or drug intake triggers a mechanism in which the brain does notcapable of regulating the production and influx of dopamine which largely compromises communication with the brain (Julien, 2005). Accordingly, the available mechanism including the work of dopamine receptors does not lead to reduction of production, especially after a person is addicted. As a neurotransmitter, dopamine plays a vital role in the brain, especially in how the brain's communication runs. In this way, the main role of dopamine is to provide the necessary transmission of signals in terms of nerve cells and this helps to facilitate the actions of the brain. In this way, the brain's actions are regulated by the uptake and flow of dopamine in the brain, however, one of the main challenges, in this case, is the role that drugs play addiction has on people's lives as it affects the production and the flow of dopamine. The increase in dopamine neuronal activity motivated by the activities of dopamine as its increase in the brain affects the functioning of the brain which largely contributes to individuals behaving in an abnormal manner. However, the activity of dopamine in the human brain creates a big problem for the individual as its increase in the brain also affects other types of hormones released in the human brain which affect how inactive the person is or how they can respond to other challenges. According to Kolb and Whishsaw (2003), the main role of dopamine is to act as a message in various organs of the body including the brain, but it needs to be regulated to ensure that it does not create problems in the human body. Activities such as nausea, breastfeeding, reward system, reinforcement, arousal, motivation, motor control and executive functions in the human brain and other parts of the body. Furthermore, the increase in the supply of dopamine in the human brain has enormous significance since it is localized only in a certain part of the brain and the increase in products limits the individual response to such changes. This affects the nervous system of individuals and has huge implications on individual life. The effect of dopamine in the human reward system also creates a great challenge in altering the behavior of individuals, but this can only be avoided if the human brain has the capacity to alter its own excess production. This helps maintain the level of production and activity of the brain which helps regulate the behavior of individuals. Through several mechanisms, drug addiction triggers excessive production of dopamine and at the same time prevents its spread to other parts of the brain, causing excessive concentration. This triggers activities such as the inability to face reality or the inability to identify what is real and what is not and at the same time increases the level of anxiety. The reward system effect of taking medications affects the inability of dopamine to communicate and use the reward system in the brain to motivate people to live a healthy lifestyle. However, the effect of the reward system triggers subsequent communication in case of addiction, motivating people to continue taking the drug and this negatively affects their inability to refrain from taking more drugs. Other aspects of the human body, such as the use of drinks and food, do not have the same effect on dopamine activation due to the excessive release of dopamine resulting from drug use. According to Nutt, King and Phillips, (2010) shows the effect that high drug intake has on the production of dopamine and its subsequent effect on the reward system. Drug use causes an increase in dopamine production almost 10 times thatnormally triggered by food consumption. Behavioral Problem of Drug TakingDrug addiction often arises as a result of individuals' inability to control drug taking. drugs. Even if people are aware of the consequences that the drug has on their body, they do not shy away from the next intake that drastically affects their lifestyle. Drug addictions are associated with cases of low productivity, deaths, cases of cirrhosis, problems such as lung cancer and the spread of AIDS. The main challenge related to drug addiction is the inability of the current method to help treat the addiction. Even though a person can undergo rehabilitation and reduce their medication intake, there is always the possibility that relapses could occur in the long term. Consequently, the long-term sustainability of treatments presents a challenge for many, especially due to the exposure a person has to other external conditions (Nutt, King, Saulsbury, & Blakemore, 2007). Even if people are aware of the consequences of taking drugs, sometimes once they lose control, they are often unable to regulate taking the drugs. There has been a large increase in rehabilitation centers to help regulate drug intake, but yet they have not been able to sufficiently address addiction. Understanding the Addiction Process Drug-related use has psychological and social implications and this fundamentally affects their lives and how they relate to others. Taking drugs triggers a biological process especially with the production of dopamine. Consumption of substances such as nicotine, alcohol, cocaine, heroin and others have a biological effect on the brain. Being a biological process, it is crucial to provide biological solutions to the addiction process. However, existing research on biological and behavioral problems has focused on animals, and this helps replicate similar behavioral problems in humans. Through this, there has been a great development in the examination of methods that can be used to provide biological process understanding of the drug addiction process. Behavioral effects such as arousal, sedation, and euphoria are normally triggered by the effect the drugs have on different proteins in the brain. Therefore, the biological effect of drug intake causes cellular and molecular reactions that alter the behavioral process in the long term. According to Tye et al (2012), almost half of individuals with addiction problems are related to genetic issues. Additionally, the family's past history of mental health has an important implication on the effect that drug addiction may have on individuals in the long term. The synaptic diffusion of the human brain, particularly the relationships with proteins in the brain, influences the behavior of individuals when taking drugs. Cellular and molecular changes in the brain also have a consequent effect especially on the behaviors of individuals. with the composition of the brain. Therefore, the biological process creates a platform where it is possible to understand the level of alteration of the brain especially with increased drug intake. Nerves have an important role to play in the human body especially because they regulate individual actions and how individuals behave when exposed to different conditions. Even if this is the case, the development and understanding of biological activities in terms of brain cells and the addiction process are limited. The circuits of the brain reward systemTaking different drugs in the human body still has a similar effect, even if they havedifferent chemical compositions. However, they have a tendency to trigger dopamine which influences the reward system circuits of the brain. The brain's reward system circuits are often activated in the same way even with the use of different drugs as they often work by amplifying the production of dopamine. The actions of the drugs trigger similar reactions which are instrumental changes in the brain and this plays an important role by altering the ventral tegmental area (VTA) and its functions in the brain. The reward system in brain activity to protect individuals from taking some of the actions that can somehow affect the effectiveness of individuals, especially understanding the biological composition of the brain. Although the brain has the mechanism to act against the action of taking drugs, this responsiveness is often influenced by the overproduction of dopamine which largely influences brain activity. However, this creates an urgency to ensure an increase in drug consumption. drugs which in turn generate Drug overriding has become a major problem worldwide and has contributed to cases of addiction. This includes those drugs purchased as over-the-counter medications and others that individuals purchase for personal satisfaction. Brain plasticity is largely influenced by the constant use of drugs which limits the effectiveness of the individual's ability to make them remember and at the same time learn what one of the functions of the human brain is (McKim, 2003). of the brain, however, includes the structure along with the chemical compositions that aid in the communication process and alter the brain process. Therefore, drug addiction triggers the mechanism where a person develops the tendency to learn the ability to take drugs which further makes it difficult for them to adopt another habit. Furthermore, the brain circuits are therefore often unable to allow the individual brain to adopt the mechanism of taking the drug. High drug intake alters individual mechanical and chemical reactions in the human brain making it difficult for the brain to alter the addictive process. Since the brain mechanism is greatly altered, it makes it difficult for the brain's plasticity to learn other behaviors and high drug consumption takes its place. This explains why, after addiction, patients often have difficulty unlearning a new way of doing things in their brain. Furthermore, the addictive process also affects an individual's ability to rely on biological functioning, especially how the human body obtains rewards. The brain normally has a learning process underway that teaches individuals new ways of doing things which is often a challenge when addiction occurs. Since the functioning of the brain arises from biological and chemical processes, altering the biological process makes it difficult for the brain to learn new things. This involves the use of drugs ranging from cocaine, alcohol and nicotine, but trigger similar actions by altering brain processes. Human brain research was derived from the functioning of animal brain which is used to understand the mechanical and biological process. as a result one of the brain's learning processes is negatively affected by blocking the pathway that facilitates the learning process as individuals continue to take drugs even when they are aware of the negative effects it could have on their lives. Using animals as a research center provides people with the ability to face challenges and adopt new ways to ensure that cases of relapse are avoided.
