Drug Effects And Their Association With Learning

Relapses and drug taking are both heavily influenced by similar factors such as the drugs neurochemistry, the user’s history, environment, and dose of the pharmacokinetics. After a period of abstinence or non-use the drugs reinstating is more often an initiation of more than one factor, namely; re-exposure to drug, stress, cues in the environment, priming of the drug to user. In the user’s mind, neurochemical responses are commonly induced through these factors, in that they create a craving by mimicking the drug and this in turn prevents reinstatement and desire to use the drug (McGovern, Xie, Segal, Siembab, & Drake, 2006).

It is where the fracture of the skull occurs due to sudden blow or sharp objects. This requires immediate medical treatment to avoid the life threatening. (Van Meter & Hubert, 2014.)

learning were significantly impaired, even after they had not used the drug for at least 24 hours.

The user may increase the amount of a drug taken due to the drug being metabolized too quickly or being removed from the body. A person may compensate their behavior when exposed to a drug overtime such as learning to drive while intoxicated. The impairment is reduced and this is known as behavioral tolerance. Pharmacodynamics tolerance is the main contributor to the need to increase the dosage of a drug in order to avoid withdrawal symptoms. The user does not feel the same effects of a dosage so the dosage must be increased in order to get the same feeling.

Cognitive enhancing drugs, or nootropics, are a category of substances that have been purportedly shown to positively impact a user’s cognitive performance in areas such as memory, creativity, motivation, and attention1. Some cognitive enhancing drugs (CED) include common medications such as Adderall, methylphenidate, modafinil with the majority of these substances, either prescribed to patients who have attentional disorders such as ADD and ADHD or memory disorders such as Alzheimer’s disease and Parkinson’s due to these positive impacts on cognition. CEDs can additionally be obtained online or in store as over-the-counter supplements2 and are not only restricted to prescription medications. Due to the shown cognitive enhancement these

Steroids have for years been associated with cheating. Though long ago it was common practice for athletes and bodybuilders to use them in order to have an edge in order to become the best, that perception has fallen away along with the careers of many famous athletes. Today the negative connotation associated with using steroids is stronger than ever before. The most recent scandal involved the allegations that world famous cyclist Lance Armstrong, a seven time consecutive winner of the Tour de France, used performance-enhancing drugs. Armstrong later admitted to using them and was promptly banned from participating in cycling events as well as stripped of his awards.

According to the biological perspective, drug use may start off as casual, but through continued use, it produces changes in the brain that influences the onset and maintenance of drug addiction. (Horvath et al., 2013). Drugs have their most prominent effects on the function of neurotransmitters. Almost all major drugs of abuse activate the reward system and cause a flood in the levels of dopamine which is a neurotransmitter that is involved in pleasure. As a result, not only do people learn to associate drug use with pleasure, but the brain also starts to reduce its own natural dopamine production in adjustment to the levels of dopamine produced by the drugs. This is called tolerance, and the consequences of tolerance are highly influential

The body, through tolerance, becomes accustomed to the effects of the drug causing a change in the functioning of the reward center in the brain. Neurotransmitters in the brain, at this point, do not function normally and the body “needs” the drug to achieve balance within the system.

However, there are many downfalls and issues experienced from taking these drugs. After the drugs deplete within an individual’s system, they will experience a drained or depressed feeling. There are also many negative long-term effects to taking stimulants. Research proves that these drugs can be habit forming and therefore addictive. Therefore, students will often increase the dosage because to continue to sustain that “feel good” effect. (Arria & DuPont,

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.

The drug-reinforcing effect is affected by the onset of action and frequency of drug administration. It is inversely related to the rate of the drug’s onset of action; oral administration of drugs is less reinforcing than

Ritalin is a prescription drug used primarily in the treatment of behavioural problems in children such as Attention deficit disorder (ADD) and Attention deficit hyperactivity disorder (ADHD) (National Drug Intelligence Centre 2006). It is estimated that 11 percent of Australians between the ages of 6 to 17 are affected by ADD or ADHD and the amount of Ritalin being prescribed has doubled in the last 10 years ( Schriever 2012).

Throughout this course I have learned many things about research at an introductory level. Research is a critical part of all of our lives in many ways. God blesses each of us with a degree of common sense and we all learn from observing others even as babies, we learned behaviors and skills by observing our parents. Walking through experiences throughout life teach us a lot we need to know as well but sometimes we have to take a better approach when we need to learn about certain things. Many of us know that what works in some situations or with certain individuals doesn’t always work or is the safest option for another situation. Controlled and precisely organized study allows scientists to compare and examine contrasting methods and concepts, also helps them to discover various approaches and be able to learn from individual’s behaviors and experiences. I will act as the case study throughout this paper in order to observe what I have learned about.

Ecstasy is both a hallucinogenic, causing hallucination, and a stimulant drug. Ecstasy is the name given to methylenedioxymethamphetamine (MDMA). It was first synthesized in 1912 by Merck chemist Anton Köllisch. Ecstasy appears to disturb the body 's ability to regulate its temperature and this can lead to serious problems with overheating of the body. Ecstasy can be swallowed as a pill or tablet or snorted like a powder. Users of ecstasy can experience a rush of good feelings, a high, and makes someone 's feelings much more intense, whether they 're good or bad feelings. Ecstasy’s effects usually last up to 6 hours.

Many psychiatric and psychoactive drugs that are available on the market, pharmaceutically or illegally, closely resemble neurotransmitters and are actually able to mimic it to the extent that it fools the receptors. Basically, these drugs hijack the neurotransmitters. Once these drugs are ingested, it enters into the brain, gets into the synapse and binds itself to the receptor. This then causes the inappropriate release of neurotransmitters and alter the breakdown and recycling of neurotransmitters or can be used to destroy particular neurotransmitters completely (Sapolsky, 2005, p. 14).
