The nervous system controls and organizes all parts of the body. The brain receives all the messages and tells the respective body parts to do their jobs. Neurons pass through the nervous system to receive and transfer messages in a form of an electrical impulse. In order for the brain to receive all the messages a special chemical known as neurotransmitters carries messages to the brain. There are many types of neurotransmitter such as dopamine, GABA, insulin etc. Neurotransmitters are found in between small gaps of neurons called the synapses. A neurotransmitter works by quickly moving over the synapse and joins to sites on other sides, in order to restart the electrical impulse. Later they are broken down and receive new messages. Neurotransmitters are important for our body to make responses but it can be damaged of destroyed by certain things such as drugs. There are many drugs that can affect them an example is cocaine and caffeine. There have been many effective solutions for these drugs but it is not proven to remove the effects on the body completely.
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...

...o drug at all do some violence may take place etc. economical impacts is low labor force since many people are taking treatments, students taking drug abuse treatments would not be able to study, higher unemployment rate etc. Some health impacts of these treatments include anxiety, headache, depression etc.
Taking drugs is a bad influence for the society. It can harm people’s life and also change the way they behave. By not taking illegal drugs the human body can function more effectively and can bring better influence to the future society. Not taking drugs can do a lot it can make the neurotransmitters work, it can bring good influence to the society, it make a country have less crime scenes and can also make our body thankful to us by not destroying them etc. Don’t take drugs just to be popular or just to show off just by being a good citizen we can be popular.
Briefly explain the process of neurotransmission. Neurotransmission starts with the neuron, the most important part of the central nervous system. A neuron contains a cell body, axon, and dendrites. When a neuron receives an electrical impulse, the impulse travels away from the cell body down the axon. The axon breaks off into axon terminals. At the axon terminals, the electrical impulse creates a neurotransmitter. The neurotransmitter is released into the synapse, a space between two neurons. If the neurotransmitter tries to stimulate a response of another neuron, it is an excitatory neurotransmitter. If the neurotransmitter does not stimulate a response of another neuron it is an inhibitory neurotransmitter. If a response is generated, the second neuron or postsynaptic neuron will receive an action potential at the site of the dendrite and the communication process will continue on. If a response is not generated, neurotransmitters left in the synapse will be absorbed by the first neuron or presynaptic neuron, a process known as reuptake. Neurotransmitters control our body functions, emotions, and
According to the document Substance abuse by World of Health, the social effects of substance abuse may include dropping out of school, losing a series of jobs, engaging in fighting and violence in relationships, and legal problems. Drugs and alcohol are a go to when one is on the street because they help them fight the agonizing pain of having nothing. However, Drugs and alcohol have their side effects that lead to the human body destroying itself which results in the inability to contribute to society. A few examples according to World of Health state, “Opioid drug users may move slowly, lose weight, have mood swings, and have small pupils. Benzodiazepine and barbiturate users may appear sleepy and slowed, with slurred speech, small pupils, and occasional confusion. Amphetamine users may have excessively high energy, sleep problems, weight loss, rapid pulse, high blood pressure, occasional psychotic behavior and enlarged pupils. Marijuana users may be sluggish and slow to react, exhibiting mood swings and red eyes with dilated pupils. Cocaine users may have wide variations in their energy level, severe mood disturbances, and a constantly runny nose. Crack cocaine may cause aggressive or violent behavior. Hallucinogenic drug users may display bizarre behavior due to hallucinations and dilated pupils. LSD can cause flashbacks” in Substance
"Cocaine delivers an intensity of pleasure - and despair - beyond the bounds of normal human experience."
Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions across that membrane, making cells more likely to become depolarized, if the neurotransmitter happens to be excitatory, or less likely if it is inhibitory.
Our economic statue tells us that a supply rapidly grows up to meet a demand. But if the demand is widespread then suppression is useless. It is harmful to society because since by raising the price of the drug in question, it raises the profits of middlemen, which gives them an even more powerful drug to stimulate demand further. The vast profits to be made from cocaine and heroin, which would be cheap and easily affordable, even by the poorest in affluent societies if they were legal. Besides, it is well known the illegality in itself has attraction for youth already inclined to disaffection.
This topic is very controversial topic because it deals with a growing body of citizens whose lives have greatly been affected by the United States government drug policies. In order to tackle the problem effectively, we need to look how it relates to economic problems, health issues, the criminal justice system and etc in our communities I look at bureau of justice statistics for statistics on National Drug Budget control, National household survey on drug abuse, prison statistics and book written by scholars on the issue.
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)
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.
The war on drugs in our culture is a continuous action that is swiftly lessening our society. This has been going on for roughly 10-15 years and has yet to slow down in any way. Drugs continue to be a problem for the obvious reason that certain people abuse them in a way that can lead to ultimate harm on such a person. These drugs do not just consist of street drugs (marijuana, cocaine, ecstasy), but prescription medications as well. Although there are some instances where drugs are being used by subjects excessively, there has been medical research to prove that some of these drugs have made a successful impact on certain disorders and diseases.
Drug abuse is part of everyday life, most of us know someone who is or was abusing drug at some point. A way to simplify a difficult time in our life, we find an exit in a product that numbs our brain to the surrounding. People find addiction through drugs, activities and action that creates chemical reaction within our bodies. Whether you love jumping off the empire state building or inject yourself with a drug, you are looking for a high that your body enjoys. The body creates chemicals which stop our self-control. According to the CDC website, “Deaths from drug overdose have been rising steadily over the past two decades and have become the leading cause of injury death in the United States.” (Birnbaum HG, web).
Drugs will even become safer for those who are willing to use them. Government regulations on drug quality will make the drugs more pure, and potent, taking the harmful additives that some drug makers put in. Like cigarettes, warnings would probably be posted on drug packages stating “The use of crack may be harmful to your health.” As well as on windows of the stores that sells the drugs. An age limit to buy drugs would probably be 21. Clean, sterile needles would also be provided to heroin users and stop the spread of diseases such as AIDS from contaminated and dirty needles.
Drugs affect your brain and in turn can alter your moods and behavior. Drugs are chemicals that tap into our brain’s communication system and disrupt the way nerve cells receive, send and process information. Drugs interfere with the exchange of information in the brain producing changes that promote repeated drug use. Drugs can imitate the brain’s natural chemical messengers, or they over stimulate the reward circuit of our brain.
The first major benefit that will come from the legalization of drugs will the increase in jobs. Creation of new jobs will take place in the manufacturing industry, sales industry, and marketing industry due to the increased demand for drugs. The manufacturing industry will experience a boost because some drugs will need to be mixed with other substances to become other drugs, such as crack cocaine. The sale industry will expand from the legalization of drugs because the drugs will not sell themselves. They are the same.
Nearly all drugs of abuse increase dopamine release. Dopamine is an important neurotransmitter in drug abuse and addiction. Dopamine plays a role in reward-motivated behaviors, motor control and important hormones. It’s known as the “feel good hormone” which is why people abuse drugs that increase the release of dopamine. Since life is unpredictable, our brains have evolved the ability to remodel themselves in response to our experiences.
Illegal drugs are used by people as a way out when feeling down about themselves. As the effects of the drugs may stay the same throughout, causes show that there are a large number of reasons for use. Being lonely, isolated, and frustrated in life help start off the drive to escape. In many cases, using drugs is a coping mechanism, especially in teens. Emotions become numb as people try to escape the pain of reality. This is seen in the youth of today as they deal with everyday pressures.. Drug abuse can make people think they are re-creating their former negative self image. This rebellious action gives the attention that is desired. From trying to fit in to hiding from problems, people will always have a choice. In the end, the reality of drug use is damaging to the user's body, mind and relationships.
