Drugs Affecting The Human Body
Brains contain many different neurotransmitters that affect humans differently. The brain uses these neurotransmitters to create different feelings and emotions within humans. A deficiency in these neurotransmitter causes problems with nerve impulses that can lead to depression. There are many drugs that can intentionally change these normal chemical processes in our brain to maintain the feeling of happiness; however, these drugs are extremely dangerous to the human body and are unhealthy for humans. `The brain is a complex organ that has a complex, but quick process of delivering the neurotransmitters to the receptors. Neurons communicate with each other by sending electrical signals, nerve impulses, through tube like structures called axons. …show more content…
Serotonin can increase self-esteem and confidence in a person. However, low serotonin levels correspond with depression and violent actions. High levels of serotonin can create a feeling of accomplishment in a person while low levels can create depression. Similar to dopamine, there are addictive, dangerous drugs that can alter the serotonin's levels in the brain. A drug that is capable of altering the serotonin levels is ecstasy. Serotonin is usually not released all at once; however, drugs like ecstasy cause serotonin to release all at once which creates strong feeling of accomplishment and an increase in self-esteem. Similar to methamphetamine and cocaine's effects on dopamine levels, anti-depressants help to keep serotonin in the synaptic gap for a longer period of time. However, anti-depressants can be legally prescribed by a doctor while some addictive drugs can be illegal. One of these anti-depressant is known as Serotonin-Specific Reuptake Inhibitors (SSRIs). Although these anti-depressants may be legally prescribed by a doctor, they can still be dangerous if they are consumed in large quantities. Both addictive drugs and drugs from a doctor can increase serotonin levels and can control the amount of serotonin in the brain, but both drugs can be harmful. This is because these drugs can cause a change in the brain chemistry of a person which causes the person to crave the drug. Once a person craves a drug, they

    One of the most common anti-depressant drugs used are Selective Serotonin Re-uptake Inhibitors (SSRI's), these are associated with serotonin which have been found to be involved in depression. The SSRI's will work by stopping the nerve cells from re-absorbing serotonin that has been released into the synapse, which in turn will increase the amount of serotonin available.…

    The biological perspective states that the brain uses a number of chemicals as messengers to communicate with other parts of itself and with the nervous system. These chemical messengers, called neurotransmitters, are released and received by the brain's many nerve cells, which are also called neurons. Neurons are constantly communicating with each other by way of exchanging neurotransmitters. This communication system is essential to all of the brain's functions. A tiny space called a synapse connects neurons to one another. Depression has been linked to problems or imbalances in the brain with regard to the neurotransmitters serotonin, norepinephrine, and dopamine. The neurotransmitter serotonin is involved in regulating many important physiological…

    Monoamines are group of neurotransmitters serotonin, noradrenaline, dopamine. It is suggested that people that suffer with depression have less of these neurotransmitters available to attach to the relevant receptor of the receiving neuron. Quite similar to that of the biomedical model this hypothesis believes that a solution to this imbalance would be to increase the number of the neurotransmitter in particular in the synapse so that there are more available to be able to attach onto the requiring receptor. This in turn would correct the mood disorder. Low levels of the neurotransmitters serotonin and dopamine are believed to play a key role in causing depression. Hirschfield 2000 cited in Datta (2010 p.59). claimed that low levels of these three monoamines can cause depression whilst increasing these levels will have the opposite effect and lift it . This is supported by Stanley and Mann; Yates et al cited in Datta (2010 p.61) who suggested that the post mortem results of those who were suffering with depression and had committed suicide had a ‘high number of serotonin receptors in the prefrontal…

    The nature side of the debate is the biological explanation which explains how when an individual takes a drug that alters the availability of one or more neurotransmitters, it affects the mood or behaviour of the person. Depressant drugs slow the brains activity and stimulants make the stimulation between one neuron to another easier. A repeated use of any drug is likely to change the chemical balances within the brain. This is due to the level of neurotransmitters in the brain being regulated. When a person takes a psychoactive drug which artificially changes the chemical levels within the brain, the mechanisms in the brain adjust the level of natural production. This results in the person then having to carry on taking the drug so that they can function normally.…

    Altered State of Consciousness, also known as ASC, is a temporary change in one's normal mental state without being considered unconscious. There are many different types of ASC but some examples would be dissociation, hypnosis and meditation. All these forms of ASC can all be achieved in different ways, and are achieved for different reasons. For example, meditation is usually used to help reduce stress, and lower anxiety. While hypnosis is used to open people to the power of suggestion.…

    Over thousands of years’ humans have made and found many drugs and consumed them with the intent to regulate certain functions in the body. Most of these drugs have side effects and affect everyone differently. When introducing the body with a drug such as Prozac, Zoloft and Paxil, all of which are anti-depressants designed to maintain proper serotonin levels, other effects may occur called side effects. Side effects can occur because of other properties introduced alongside the drug or an unsuccessful attempt to properly regulate the serotonin levels. Some common side effects with anti-depressants are weight loss or gain, insomnia or day time sleeplessness, nausea, anxiety and in extreme cases increase in suicidal thoughts. People with different disease and disorders may react differently to certain drugs.…

    Pain-killers, antidepressants and tranquilizers are chemicals that affect the activity of neurotransmitters in our body. Neurotransmitters ultimately affect our emotions. Here is how: A research conducted on 11 participants which “compared amygdala activation in response to masked emotional faces before and after antidepressant treatment”(Sheline 251) was observed by using fMRI scanning. The “amygdala is the integrative center for emotions, emotional behavior, and motivation” (Wright). Sheline concluded that “Depressed patients had exaggerated left amygdala activation to all faces, greater for fearful faces. Right amygdala did not differ from control subjects. Following treatment, patients had bilateral reduced amygdala activation to masked fearful faces and bilateral reduced amygdala activation to all faces. Control subjects had no differences between the two scanning sessions.” (Sheline, 651). This comes to show that chemicals can activate and deactivate certain parts of the brain, ultimately affecting the emotions of human beings. However, these drugs also carry negative side effects with it, such as weight gain, sexual dysfunction, and the anxiety felt by the discontinuation of it, states Ferguson (22). “A diversity of better-targeted drugs is on its way, and many will be tailored to the individual” (Martin, 261). Martin (265) states that in…

    The debate over antidepressants has waged on for over more than half a century. Two heads of the Department of Psychiatry in Washington University discovered that depression was just as much biological as it was physiological meaning that people with depression had an abnormal chemical make-up in the brain. This discovery increased the demand for research on methods to alter this abnormality effectively and efficiently. Thus antidepressants were created, sparking a psychiatric revolution. Antidepressants work by blocking the reuptake of serotonin. Serotonin is a neurotransmitter that is responsible for controlling human emotions. Our bodies make serotonin naturally but some particles are lost on the neuron, which is called reuptake. Antidepressants block the reuptake by placing a protein wall on the neuron, enabling a greater consumption of serotonin in the brain (Greenburg Manufacturing). From their creation, antidepressants have given people a chance to recapture the enjoyment they once, or never, had. They help people find their goals, rediscover their futures, and enjoy special moments in life that should be cherished. Antidepressants should be prescribed to individuals suffering from depression because they are simple, safe, and effective.…

    In drug-related prosecutions, the State bears the burden not only of proving the elements of the offenses of sale and possession of shabu under Republic Act No. 9165, but also of proving the corpus delicti, the body of the crime. “Corpus delicti has been defined as the body or substance of the crime and, in its primary sense, refers to the fact that a crime has been actually committed. As applied to a particular offense, it means the actual commission by someone of the particular crime charged. The corpus delictiis a compound fact made up of two (2) things, viz: the existence of a certain act or result forming the basis of the criminal charge, and the existence of a criminal agency as the cause of this act or result.” The dangerous drug is itself the very corpus delicti of the violation of the law prohibiting the possession of the dangerous drug. Consequently, the State does not comply with the indispensable requirement of proving corpus delicti when the drug is missing, and when substantial gaps occur in the chain of custody of the seized drugs as to raise doubts on the authenticity of the evidence presented in court.…
