How Do Drugs Affect The Brain

Some of the psychological effects are paranoia, depression, or suicidal thoughts. Some physical effects are rapid heartbeat, sleepiness, HIV, hepatitis from sharing needles, and respiratory problems. “Once you get started, it can be very hard to stop”. (Calabria et al., 2010, as cited in Cooner & Mitterer, 2016, p. 181). For example, I know someone that decided to try marijuana for the first time. What he did not know was the person had put cocaine in with it. After trying it that first time he did eventually become addicted to drugs and he even started doing heroin. Drugs affect three parts of the brain the cortex, limbic system, and the brain stem. Drug addiction affects the way the brain communicate and the way neurons send, receive, and process information. “Addictive drugs increase dopamine activity.” (Boyd, Harris, & Knight, 2012, as cited in Cooner & Mitterer, 2016, p.

This book covers one of the most destructible problems to society which is drug abuse followed by crime and violence. Many people don't know and underestimate how others become addicted to drugs. They think that people who use drugs do not have moral principles and that they could stop drug use simply by just choosing and saying so. In reality, drug addiction is a complicated disease, and quitting takes more than good intentions or a strong will. Drugs change the brain function and how it works that makes quitting hard, even for those who really want to. Fortunately, after many researches and experiences with others scientists know more about how drugs can affect the brain and found treatments that can assist people to heal and recover from

Reading this text I have realized that drugs can and will have a big effect on a persons life mentally physically and spiritually.It is actually depressing to see what

Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces a greatly amplified message, ultimately disrupting communication channels.

Drugs some use them to escape pain, others use them for pleasure, and some use them to just fit in. Either way drugs are a harmful substance that may seriously affect the body. Drugs mess with the brain in ways that we couldn’t even imagine. From destroying brain cells that help with critical thinking to destroying cells that give us the ability to feel pleasure. Drugs take the place of our natural body functions of the body. They fool receptors of the body and make it to where our bodies produce less of what we need. Over a period of time this may produce very severe consequences on the body. With all the risks involved with drugs it’s a wonder why some people use them.

Drugs and narcotics can bring down the best of us, but, in doing so, they can also shed light into our lives.

Repeated heroin use changes the physical structure and physiology of the brain, which makes imbalances in neuronal and hormonal systems. Heroin use may cause deterioration of the brain’s white matter; this affects the ability to make decisions, behave normally, and act during stressful situations. Heroine also creates tolerance, which makes the user’s body dependant on it.

The brain consist of several large regions each responsible for some activities vital for living .The brain is made up of millions of nerve cells. A neuron contains three important parts; a central cell body that directs all activities of the neurons. Short fibers that receive messages from the neurons and relay them to the cell body. And an Axon a long single fiber that transmits message’s. Most neurons contain three parts but are very diverse. The transfer of a message from the axon of one nerve cell to the dendrites of another is known as neurotransmission. These messages don’t do not occur through direct contact. The effects of drug abuse on the brain range from bad to very bad. If you do something pleasurable and good the brain tends to

This will effect the messages that these chemicals should be sending. Drugs have both short and long term effects on the use, some short term effects are: drug-induced anxiety disorder. This can create severe anxiety and panic attacks. There is also drug-induced mood disorder. This means that there are times where you can feel irritable, tired, sad, depressed, it can cause impulsive behaviour and racing thoughts. Some long term effects are: depression, which can be cause by ecstasy. Another effect is schizophrenia which is where the user may hear voices in their head and believe that people are trying to harm them. The risks of schizophrenia are higher for younger people, and people who smoke cannabis more often, as schizophrenia can be caused by cannabis. Using drugs can also cause cardiovascular disease, strokes, cancer, HIV/AIDS, lung disease, hepatitis B and C and damage to internal organs such as the liver, lungs, brain, throat and

I have learned some valuable information about substance abuse and addiction, especially about how the use of drugs and alcohol affect the brain. Psychoactive drugs and compulsive behavior will destroy the brain cells if the activity is practice for a long period of time. According to Inaba & Cohen (2014) say psychoactive drugs and compulsive behavior “overwhelm the brain’s ability to rebalance itself and can induce epigenetic changes that can last a life time” (p. 145). I have learned from reading the book Uppers, Downers, All Rounders’, 8th edition written by Inaba & Cohen (2014) reveals gambling is a serious addiction for the gambler. There are four levels of gambling that classify as an addiction that I did not know, so that was new insight

Drugs have been around for a very long time. They are used for a variety of reasons. Some of these reasons include relaxation, socialization, curiosity, stress relief, or a form of escapism. However, most people don’t know the threats and danger that it can cause to the body. In this paper, we are going to examine the changes that happen inside the brain due to the effects of different drugs. We will look closely at how drugs such as hallucinogens, ecstasy, cocaine, heroin, and cannabis affect an individual psychologically. I will explain the origin of the drugs, how a person feels while on the drug, how the drugs

An individual’s behavior and emotion becomes chemically altered often resulting in dependency, aggression, onset of diseases and poor judgement. This poses a dangerous threat to the neurotransmitters since they have multiple jobs in different parts of the brain. Drugs of abuse are able to exert influence over the brain reward pathway either by directly influencing the action of dopamine within the system, or by altering the activity of other neurotransmitters that exert a modulatory influence over this pathway. These drugs are often powerful and have been known to trigger schizophrenic behavior and can also cause a person to cease breathing, for example hallucinogens such as LSD, mescaline, and psilocybin are able to artificially stimulate the serotonin receptor (Sapolsky, 2005).

Strong drugs, including drugs like amphetamine and cocaine, cause the neurons in your brain to give off extreme amounts of natural transmitters that the brain already produces on its own. This ultimately can disrupt many of the brains channels. Other drugs, including marijuana and heroine, activate neurons that mimic these same neurotransmitters.

Today we are going to be talking about drug addiction and substance abuse, We are also going to be talking about the effects drugs have on your brain. First things first let's establish with substance abuse is.

Have you ever dealt with the effects of drug addict? A drug is a person who is addicted to drugs or alcohol, which has a psychological effect when ingested or otherwise introduced into the body. The effects of drug use can vary depending on the person. According to “Causes and types of narcotic addiction: A Psychosocial View” in the Psychiatric Quarterly it says, “The causes of drugs stem from the manner of which you were introduced to it whether it be by abnormal curiosity, chance encounters with addicts and narcotic peddlers, or prolonged illness” (Ausubel). The effects of drugs can be have different effects on everyone differently depending if its for pleasure or for relieving pain Most of the effects of drugs occur in the brain, where it increases the level of dopamine at a specific site possibly giving the addict the pleasure they were feigning for (Robbins). As a child I didn’t know much about drugs except for what your parents and teachers at school tell you which is, “Just Say No.”
