Mooding Disorders: The Effects Of Drugs On The Brain

According to Csiernik, “Psychoactive drugs work by altering an individual’s mental processes, including cognition, and affect through decreasing, increasing, disrupting or balancing central nervous system activity” (Csiernik, 2014). In addition, “This is turn produces changes in mood, perception, sensation, need, consciousness and other psychological functions and ultimately changes in behaviors” (Csiernik, 2014).

According to the National Institute of Drug Abuse, the brain regulates your body’s basic functions; enables you to interpret and respond to everything you experience; and shapes your thoughts, emotions, and behavior. In other words your brain controls the everyday functions needed to live a normal life. There are substances that can however, interfere with these functions, they are known as drugs. Some drugs when used as prescribed by doctors can be very useful in treating certain conditions in the body. Other Illegal drugs or prescription drugs used illegally can have detrimental effects on the body, specifically the brain. Drugs, however, can alter important brain areas that are necessary for life-sustaining functions and can drive the compulsive drug abuse that marks addiction.

For drugs to have an effect on someone, it must enter the person’s body and bloodstream so it can interact with the person’s brain. Drugs that enter the bloodstream faster tend to have more of an intense effect. Drugs affect a persons feeling, and behavior because it disrupts the communication between the brain cells. Some drugs mimic neurotransmitters; for example, heroin, and oxycontin. They change the brains opioids, so it will stimulate their receptors. Some drugs alter the neurotransmitter, by interacting with the components that sends and receives information. Also, some drugs alter the neurotransmitter by increasing and decreasing receptors.

All drugs have an effect on the brain. Addictive drugs primarily target the dopamine system, creating a 'rewarding' feeling. Within seconds of drug intrusion in the body, the drugs bring about dramatic changes to synapses in the brain. Because addictive drugs triggers a rewarding sensation within the brain, they produce a euphoric, pleasuring state of being.

Drugs, one of the leading killing drugs in the world, the one one responsible for millions of deaths. Drugs like Heroin and Marijuana have chemical structures that copy that of a neurotransmitter that naturally occurs in our bodies. These drugs are all chemicals that we keep putting into our bodies either by smoking, injecting, eating, or inhaling all these drugs temper with the nervous system in the brain that usually send, receive, and process information. Drugs can imitate the brains natural chemical messages, or either overstimulate the “reward circuit” of the brain. Other drugs like Cocaine and Methamphetamine can cause problems with the communication channel.

there are three main parts that drugs affect in the brain. these three sections are called the brain stem, the limbic system, and the cerebral cortex. some effects drugs can have on the human brain is the Imitating the brain’s natural chemical messengers and overstimulating the “reward circuit” of the brain. some other effects is that neurons may die and a very large amounts of dopamine to flood the system. drugs also cause problems with communication channels.

People take drugs to have a feeling of euphoria. For example cocaine sends a euphoric feeling to certain parts of the brain (even though the cocaine itself reaches your whole brain). Cocaine blocks the removal of dopamine from the synapse by binding to the dopamine transporters. This causes a continuous stimulation of receiving neurons, probably responsible for the euphoria reported by cocaine abusers. Cocaine lowers the amount of glucose transmitted to the brain, which is the brain's main source of energy. This disrupts many brain functions.

Drugs are chemicals that affect the brain by tapping into its communication system and interfering with the way that neurons are sent. Tolerance occurs when someone consumes a drug so many times, the response is different than their initial response. It takes more of the drug to produce a bigger effect. For the brain to build up tolerance, when the drug enters the body and goes to the brain, it activates a variety of neurotransmitters receptors causing nerves to dump its other neurotransmitters, sending signals to the brain to make more or less, turning receptors on and off, growing new interconnecting neurons. This helps the brain create a better tolerance for the drug and deals with it better the first time the drug was introduced. Understanding on how the chemicals in the brain works helps us address this issue that illegal drugs are bad for the brain and body. Without our knowledge on how drugs chemically affect the brain and body, kids today would not have the understanding on the risks of doing drugs. People doing these drugs would not understand what is happening to their body and what is going on in their

We all remember the commercials saying that drugs will “scramble” your brain, but how exactly do drugs affect it? Well, when our brain becomes affected by drugs, we form pleasurable memories and associations with them, the places we were at, and the people we were with. This is one of the reasons why seeing a picture of someone else use, or going back to a place you used frequently, can trigger a desire to use. This is especially true in cocaine users. Glutamate is a neurotransmitter that’s altered by drug abuse. And when the optimal amount is altered by drug abuse, the brain attempts to compensate for this change. This can cause impairment in cognitive function. Also, there was a study of binge drinkers and regular non-binge drinkers during

Therefore drugs are chemicals that influence the brain by taking advantage of its communication system and meddling with the way the neurons typically sends, process data and receives. A few drugs, for example marijuana and heroin, can activate neurons can actuate neurons on the grounds that their chemical composition impersonates that of a natural neurotransmitter.

Drugs are like chemicals that tap into the brains communication system and interfer with the way that the neurons normally send, recieve, and process information. Marijuana and heroin, activate neurons because of their chemical structures mimic a natural neurotransmitter.

The brain is a complex organ within the human body. It serves as the basis for all bodily functions, controlling all aspects of a human being from the complexity of experiencing emotions to the basics of breathing and walking. But what happens when drugs are introduced to the body, the brain? The studies hereafter will display the effects of drug use and abuse on the brain and its functions.

There are many reasons why people use drugs in their everyday life. Whether it be for recreational use, prescribed, or bought off the street because people believe they need them to feel better. These drugs are often abused and not used for their intended purposes. After studying many theories that help explain these reasons, two stand out the most to me. One being the best and the other the worst of reasons why people take part in drug use.

Drug abuse is when people use substances that are considered legal or illegal in an abusive way. Some people use the drug repeatedly for pleasure, alleviating stress or to avoid reality. It has also been abused by those who are on prescribed drugs that are used in ways other than what it is prescribed for or using someone else’s prescription. As a result of persons who can’t control themselves and have over usage, people become addicted even when there are negative consequences (National Institute on Drug Abuse, n.d.).

Drugs negatively impact user’s health, physical abilities, wealth, and social status. Despite all these reasons why would anyone even do these narcotics? Well according to NIDA there are three main reasons which factor into a person’s becoming addicted to drugs; firstly they state “The genes that people are born with accounts for about half of a person’s risk for addiction.” To summarize it states if you’re descended from a habitual drug abuser, you’re more likely to also become addicted to the substance.
