Essay on Effects of Cocaine, Seratonin and Melatonin on the Brain

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

1. Explain how the use of substances alters a person’s state of consciousness, including depressants, stimulants, and hallucinogens. Include in this explanation what happens to the neurotransmitters and body chemicals as well as how you might recognize whether a person at work or in your family is in an altered state of consciousness due to the influence of drugs.

Cocaine influences dopamine, norepinephrine and serotonin neurotransmission by inhibiting their reuptake. Pimozide, alpha-flupenthixol, perphenazine and chlorpromazine, all dopamine antagonists, were used to pre-treat rats in an attempt to demonstrate the reinforcing effects of dopamine.

The historical drug/alcohol themes: 1) There is a basic need of human beings to cope with their environment and enhance their existence and 2) Human brain chemistry can be affected by psychoactive drugs, behavioral addictions, and mental illness to induce an altered state of consciousness. It can also be affected by heredity and

Other drugs, such as amphetamine or cocaine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This disruption produces

The purpose of this research paper is to examine the different effects of different types of hallucinogenic drugs on the human brain. The paper will focus specifically on LSD, DMT, and Shrooms as they are amongst the strongest types of drugs in their category. The chemical structure of the different drugs and the way they alters chemicals in the brain will be examined as well. This topic is worth investigating because if you or anyone you know is interested in trying LSD, DMT, and Shrooms, it is important to know the effects they will have on your brain if you are unaware or don’t

brains get affected. A solution would be to find away to get rid of this drug and not to

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).

The neuro-developmental effects of these chemicals are comparatively well-known, while their impact on human conduct has yet to be fully comprehended.

Although we would not be here without having the knowledge of physical changes in the brain, knowing about the chemical impacts in the brain play a big role in today’s society. Learning about the chemical changes happening in the brain changes the way doctors perform surgery, they way antibiotics are made, and the way people view schizophrenics and other mentally ill patients. Our understanding on how physical changes impact the brain makes a bigger impact on human lives.

Throughout history, people have used different kinds of drugs to alter the way they feel or

The drug Cocaine alters chemical levels in the brain which can lead the user to have the ‘feel good’ factor.

Drugs of abuse, such as cocaine, ecstasy, heroin and cannabis, are of natural or synthetic origin, which can alter the emotional state, perception, body functioning and behaviour of an individual. Drugs are known to work in the brain by activating certain brain circuits via different mechanisms, and stimulate or inhibit different neurons in the pathway. However, due to the effects of each drug being different, a drug will affect either different pathways and neurons in the brain to that of another, or through a different process, i.e. direct or indirect activity. This essay will discuss the different mechanisms of action that cocaine, ecstasy, heroin and

By behavioral mechanism of drug action, we refer to a description of a drug's effect on a given behavioral system (1ocus) expressed in terms of some more general set of environmental principles regulating behavior. Specifying the behavioral mechanism(s) responsible for an observed effect involves: a) identifying the environmental variables which typically regulate the behavior in question, and b) characterizing the manner in which the influence of those variables iS altered by the drug. In some Instances, the drug
