The Effects of Addiction on the Brain Addiction is a condition that results when a person ingests a substance (e.g., alcohol, cocaine, nicotine) or engages in an activity (e.g., gambling, sex, shopping) that can be pleasurable but the continuation of which becomes compulsive and interferes with ordinary responsibilities and concerns, such as work, relationships, health, or all the above. The Diagnostic and Statistical Manual of Mental Disorders no longer uses the terms substance abuse and substance dependence, rather it refers to substance use disorders, which are defined as mild, moderate, or severe to indicate the level of severity, which is determined by the number of diagnostic criteria met by an individual. Substance use disorders occur …show more content…
Different drugs — because of their chemical structures — work differently. There are at least two ways drugs work in the brain. Drugs imitate the brain’s natural chemical messengers and overstimulate the “reward circuit” of the brain. After repeated drug use, the brain starts to adjust to the surges of dopamine. Neurons may begin to reduce the number of dopamine receptors or simply make less dopamine (Recovery, 2013). The result is less dopamine signaling in the brain — like turning down the volume on the dopamine signal. Because some drugs are toxic, some neurons also may die. As a result, the ability to feel any pleasure is minimized; the person feels flat, lifeless, and depressed, and is unable to enjoy things that once brought pleasure. Now the person needs drugs just to bring dopamine levels up to normal, and more of the drug is needed to create a dopamine flood, or “high”—an effect known as …show more content…
In fact, according to Substance Abuse and Mental Health Services Administration, there are currently six different subcategories related to Substance Use Disorder (SAMSHA, 2015). It goes without saying that long-term drug use will no doubt take its toll on the brain. For example, new research from the National Institute of Health in a Science Education Study on ecstasy, ice and speed users in Australia suggests that long-term use of these drugs is likely to cause brain damage. The brains of 30 patients who had been treated in the ER for amphetamine-related problems were scanned for this particular study. Out of the 30 patients, 6 of them showed signs of brain damage, which the doctors said showed up as an “unidentified bright object” on the frontal lobe during the scan. The results of the study concluded that one in five has suffered a likely drug-related brain injury. Additional emerging evidence also suggests that long-term amphetamine use may cause anxiety, depression, memory disturbance, and psychosis (Narconon,
Addiction may be defined as the chronic use of drugs alongside the problems resulting from their use. Despite the person being aware of the consequences of using the drug, he continues to use it. If not attended to, addiction may cause serious social problems and even death (Hanson et al. 36). In order to address drug addiction, it is vital to understand addiction itself and where it stems from.
There are many different definitions in which people provide regarding addiction. May (1988) describes that addiction “is a state of compulsion, obsession, or preoccupation that enslaves a person’s will and desire” (p. 14). Individuals who suffer from addiction provide their time and energy toward other things that are not healthy and safe. The book
Drugs are substances that disturb this delicate balance, because they have “passkeys” that let them open certain “locks” located between the neurons. The brain automatically adjusts to these substances from outside the body by producing fewer of its own natural “keys”. Cocaine is type of drug that affects the dopamine is a neurotransmitter which is connected with emotions and noradrenalin is connected with alertness. Cocaine is considered as an illegal drug in most countries but some considered it as an legal drug. Although cocaine is an illegal drug earlier ancient people used to coonsider it as a medicine to treat many illness. Cocaine is absorbed in the dopamine and the...
Addiction controls people in many ways. Some addictions can even lead to death if not stopped early on. Addiction to any kind of substance or drug is not an easy thing to quit. It is hard to quit because it is not physically hard but also mentally hard to end an addiction. Addiction controls people by making them lose control of their actions and cravings. Also addiction controls people by changing their circadian rhythms which make it hard to stay away from what they are addicted to.
The word Addiction was started out just being used for a person who could not stop either doing drugs or drinking alcohol. Even though those are the most common things addicts are addicted to there are other things people can be addicted to. Now the term addiction is used for a person who can not stop doing anything such as gambling, having sex, tanning and the list goes on. The person who is using this substance or is doing this behavior have consequences, rather its effecting there body or them personally and their family. Despite the consequences, the person that has the addiction still does it. Before what the person is doing becomes an addiction, it is something that is done because they enjoy doing it. It becomes an addiction when ...
Drugs seem to cause surges in dopamine neurotransmitters and other pleasure brain messengers. However, the brain quickly adapts and these circuits desensitize, which allows for withdrawal symptoms to occur (3). Drug addiction works on some of the same neurobiological mechanisms that aid in learning and memories (3). "This new view of dopamine as an aid to learning rather than a pleasure mediator may help explain why many addictive drugs, which unleash massive surges of the neurotransmitter in the brain, can drive continued use without producing pleasure-as when cocaine addicts continue to take hits long after the euphoric effects of the drug have worn off or when smokers smoke after cigarettes become distasteful." (4)
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 most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
Addiction /ə-ˈdik-shən, a-/ noun 1. A strong and harmful need to regularly have something (such as a drug) or do something (such as gamble), 2. An unusually great interest in something or a need to do or have something (Addiction). Addiction can cause a person to sabotage their lives in order to get their next fix, whether that be scoring another gram of coke or a double with cheese, a large fry, and a large soda. Addicts are stuck in a constant cycle of getting cravings, going through with their ritual, using, experiencing guilt, and being emotionally triggered, thus bringing them back to the beginning. Now, most people when they hear the word “addiction”, the first thing that comes to their mind is drugs. However, if a vast majority of individuals
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
Opium has negative and positive affects on the brain and this dynamic of affects can also be seen with its behavioral and health effects depending on length and frequency of the usage. At the start of opium usage users experience positive effects including a sense of euphoria, relaxation and a decrease pain which stems from its analgesic properties. Then shortly thereafter individuals begin to feel lethargic. Unfortunately, extended usage of opium comes with negative behavioral changes. These range from changes in libido, which is often inhibited as well as increases in anxiety or in mood disturbances. Opium usage has also been shown to increase the risky behaviors of users. These risky behaviors will usually stop upon cessation of opium usage
Addiction, a compulsive psychological need for a habit-forming substance according to an online dictionary (p). In this instance, the substance is sex or masturbation. A sex addict needs progressively more and more explicit pornographic material in order to become aroused. Their behavior becomes centered on different sexual experiences and the desire to attain them. The person cannot control their sexual appetites resulting in severe consequences for themselves and others. Sex addiction is a lifelong problem that needs to be contained in order to avoid continued complications. Shame, secretiveness, and abusiveness in a person accompany the addiction. Treatment is available in different forms; however, because this subject is relatively new a cure is not known. An important question is arising around this subject is whether or not sex addiction results from nature or nurture.
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.
Addiction is a progressive, chronic, and ultimately a fatal disease. It is progressive in the sense that if it is left untreated it will get worse. Chronic means long term. Once one becomes dependent, it is like diabetes, in that diabetes is an incurable disease that can only be controlled. Long-term addictions have the high potential to lead to death through overdose, AIDs, suicide, or an accident (Aronson 17). The cycle of addiction tends to follow a pattern.
