Also, the brain releases less dopamine. Bringing back the initial euphoric feeling requires consumption of more alcohol. Therefore, the addict looks for larger amounts of drugs and builds up a tolerance. A drug user or an addict cannot perform daily activities well without alcohol or other substances in the system. Chronic addiction affects parts of the brain negatively, which leads to memory loss, poor decision-making, poor judgments, and immoral behaviors. These effects on the brain from drugs are long-lasting. Symptoms of Drug Abuse and Addiction There are several alcohol addiction symptoms. Some of them include weight loss, stammering, red pupils, hallucinations, instant change in moods, aggressiveness, neglecting responsibilities, financial problems, unhealthy friendships, isolation, and restlessness. Additionally, due to change in eating habits, an addict of alcohol or other substances can look undernourished. Addiction Treatment Options Most drug addicts deny that they have a chronic problem.

Addiction is defined simply as a strong and harmful need to regularly have something (such as drugs) or do something like gambling (Addiction, 2016). Addiction can be crippling and can control all aspects of your life to the point of not being able to function as a productive member of society. Addicts can have a life long struggle, even once sober, or clean, from the addiction.
Drug addiction is often characterized as being a complex brain disease that causes compulsive, uncontrollable, drug craving, seeking and use without any regards to the consequences they may bring upon themselves, or society. As long as the brain is exposed to these large amounts of dopamine on the reward system, it will inevitably develop a tolerance to the current dopamine levels, which it is receiving, lessening the pleasure the user will experience. In order to satisfy the brains “reward...
George F. Koob defines addiction as a compulsion to take a drug without control over the intake and a chronic relapse disorder (1). The Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association defined "substance dependence" as a syndrome basically equivalent to addiction, and the diagnostic criteria used to describe the symptoms of substance dependence to a large extent define compulsion and loss of control of drug intake (1). Considering drug addiction as a disorder implies that there are some biological factors as well as social factors.
Drug addiction is more complicated than medicine thought in previous years. It’s not because someone is weak or unable to control themselves. They are chemical such a dopamine in the human body that makes the process difficult. The brain works in a neuropath way and drug interrupt the normal process which stops the frontal lobe to work as it should. Treatment isn’t done right and patients tend to repeat their habit after they get out of rehab. Psychological treatment is not as effective as chemical injection for dopamine to reward the brain. However, even after the treatment is complete, it will be a life struggle to stay away from drugs since the brain will always look for a simpler way to reward itself.
“Addiction is a brain disease expressed in the form of compulsive behavior,” says by Alan Leshner in his article, “Addiction Is a Brain Disease” featured in the book Drug Abuse: Opposing Viewpoints. Addiction has a variety of meanings depending on what your viewpoint of addiction. According to dictionary.com, the concrete definition of the word addiction is, “the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming, as narcotics, to such an extent that its cessation causes severe trauma.” Basically various doctors and therapist consider addiction to be a genetic disorder. “Provocative, controversial, unquestionably incomplete, the dopamine hypothesis provides a basic framework for understanding how a genetically encoded trait — such as a tendency to produce too little dopamine — might intersect with environmental influences to create a serious behavioral disorder. Therapists have long known of patients who, in addition to having psychological problems, abuse drugs as well. Could their drug problems be linked to some inborn quirk?” (Nash, and Parker, pg 2 of 8). Along with addiction being possibly a genetic disorder, a minority of scientist believe that the word ‘addiction’ is too broad in its denotation. “If addiction means ‘compulsive, out of control use of a dangerous drug’ is this the same as a person’s being ‘addicted’ to a cell phone? Scientist cannot work or live with this imprecision.” (Erickson, 2 of 253). They believe that the word is misunderstood in denotation. “It is important to correct the common misimpression that drug use, abuse and addiction are points on a single continuum along which one slides back and forth over time, moving from user to addict, th...
Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, according to the National Institute on Drug Abuse. Addiction is normally thought of as drug abuse and alcoholism but people can also be addicted to things such as gambling and sex as well. The controversy on if addiction is a disease or a choice is a continuous debate. Everyone has an opinion on this topic, one side believes it’s a disease, while the other believes it is a choice. Although addiction has been assumed to be a lack of willpower and a weakness, addiction is actually a complex disease that changes the wiring of the brain. Addiction is a brain disease expressed in the form of compulsive behavior (Leshner.) Both devolping
The brain becomes accustomed to the chemical changes caused by the chemical changes caused by the substance. It begins to alter its normal production and starts releasing neurotransmitters. The user begins to lose control and has difficulty limiting their drug intake; the need to consume the substance becomes more compulsive because it has affected the region of the brain that controls impulse, behavior, and craving.
Main Point: What defines an addiction? According to Psychology Today, “Addiction is a condition that results when a person ingests a substance…. or engages in an activity….that can be pleasurable but the continued use/act of which becomes compulsive and interferes with ordinary life responsibilities, such as work, relationships, or health.” This can range anywhere from drug use to eating disorders, to gambling, to even texting in today’s generation. Shocking to say the least, especially when most people do not even know they are addicted or are an addict until they realize this definition.
Addiction is a very strong word that brings along many negative connotations. When we think of an addiction we imagine someone who depends on a certain substance, most likely alcohol to have their needs met. Addiction is defined by the Webster dictionary as, "a compulsive need for and use of a habit-forming substance (as heroin, nicotine, or alcohol) characterized by tolerance and by well-defined physiological symptoms upon withdrawal." Even though our society sees addiction and only applies the word to drug addicts and alcoholics, there is a much wider range of subjects that fall under the umbrella of what an addiction truly is. An addiction is a dependency on any kind of materialistic object that you use on a day to day basis that brings
Substance abuse disorders are common in our society. It is a disorder that each one of us will most likely experience through a family member, friend, or our self. I felt very drawn to this topic due to the fact that I have a family that has background of substance abuse and I myself have battle the demon. Not until I struggled with my own addiction did I become more tolerable and understanding to those that have a substance abuse disorder. Substance abuse is not something anyone wants to have; it is a disorder that takes control of a person’s life. It is a beast that tears a person apart; from their being to the lives of their loved ones. This disorder is not biased in anyway; rich or poor, male or female, employed or unemployed, young or old, and any race or ethnicity” (E Not Alone).
Drug abuse and addiction are issues that affect people everywhere. However, these issues are usually treated as criminal activity rather than issues of public health. There is a conflict over whether addiction related to drug abuse is a disease or a choice. Addiction as a choice suggests that drug abusers are completely responsible for their actions, while addiction as a disease suggests that drug abusers need help in order to break their cycle of addiction. There is a lot of evidence that suggests that addiction is a disease, and should be treated rather than punished. Drug addiction is a disease because: some people are more likely to suffer from addiction due to their genes, drug abuse brought on by addictive behavior changes the brain and worsens the addiction, and the environment a person lives in can cause the person to relapse because addiction can so strongly affect a person.
The symptoms of alcoholism vary from person to person, but the most common symptoms seen are changes in emotional state or stability, behavior, and personality. "Alcoholics may become angry and argumentive, or quiet and withdrawn or depressed. They may also feel more anxious, sad, tense, and confused. They then seek relief by drinking more" (Gitlow 175).
There are many addictions in the world, and drug addiction is the biggest. People may experiment with the drug for many reasons. “If your drug use is causing problems in your life, then you likely have a drug abuse or addiction problem”.(Lawrence Robinson pg.1) Many people start out using drugs by peer pressure or out of their own curiosity. Stress, anxiety, lows self-esteem and depression could be another factor to start using drugs. The drug takes over your body and gives you a good feeling that many people tend to enjoy. The urge to use the drug can keep increasing rapidly after the first use. The urge can become so severe that your mind can find many other ways to deny the factor of addiction. Very few drug addicts can feel and realize when they have crossed the line with drugs. A drug addicts mind can build up a very large tolerance for the drug that they start to abandon the activities they used to do on a daily basis like showering, hobbies, socializing and even being associated with family members. The person with the addiction will continue to use the drug knowing that it is harming there body, but they don’t have any remorse. A drug addict will often try to hide their problem, so they can continue to use without anyone’s input. Family and friends may try to use preaching methods or tell the user that they need to stop using the drug. This method is not ...
