Abstract: Resent research has shown that marijuana has a negative effect on college students’ academics. Researchers have come to this conclusion because of two main problems that are associated with smoking marijuana. Smoking marijuana has been shown to alter brain function and brain structures when chronically used by adolescents and young adults. Research has also found that marijuana use during college decreases students’ academic motivation to do well. Students who use marijuana frequently have also been shown to skip class move often and have lower GPA’s. In this paper these two problems that is associated marijuana will be discussed at greater detail, and my own original contribution will be discussed. This original contribution was …show more content…
These regions are responsible for high order cognition. The average first use of marijuana occurs at age 17. The effects of marijuana on brain development and brain function is a major public health concern. In the brain, neuro-maturation is still happening in several areas of the brain during adolescence and emerging adulthood. There are also anterior and superior regions developing into adulthood, such as the prefrontal cortex (PFC) and parietal lobes (Price 2015). The PFC is classified as a multimodal association cortex that constructs memory, perception, and the cognitive processes in the brain (Siddiqui 2008). The PFC is in the front of the brain, and it is the last part of the brain to develop in a human. Because of this delayed development, it is very sensitive to marijuana use when growing. The PFC is divided into smaller portions such as it’s medial, lateral, and orbital surfaces. It is a very large portion of the brain. Shazia Siddiqui, a doctor in psychiatry says, “Its relative size reaches a maximum in the human where it constitutes 30% of the cerebral mantle. The PFC occupies one-third of the entire human cerebral cortex.” The PFC has many different jobs to do in the brain. As Siddiqui says, “PFC is often classified as multimodal association cortex as extremely processed information from various sensory …show more content…
The Hippocampus has long been associated with the acquisition of new memories. It also has involvement in episodic memory, which is a memory of a specific event from the own individual’s viewpoint (Burgess 2002). The Hippocampus is part of a system in the brain that deals with memory. This system is called the limbic system. The Hippocampus is not just involved in memory, though; It is also involved in emotions throughout the body. As Inna Kogan says, “The hippocampus is crucially involved in both memory and the neuroendocrine regulation of stress hormones” (Kogan 2008). In a study, the hippocampus was found to be very sensitive to the use of marijuana. The more marijuana that was used, and the younger that the user was, the more damage to this area there was. It was also noted that the younger one uses, the more likely they will be addicted in the future. Adolescents who start experimenting with marijuana early have a documented eight-point decrease in IQ as adults, compared with those who never used marijuana (Anderson 2015). In one study, conducted by Krista Medina, it was found that “As with alcohol, cannabinoids appear particularly neurotoxic to hippocampal neurons. Adult human users (ages 21–35) show decreased gray matter density in the right parahippocampus and bilateral hippocampus” (Medina 2007). Another study also examined if prolonged marijuana use in adolescents
About one out of five 10th graders and about 1 out of four high school seniors used marijuana in the past month (Facts for Teens, 1). It is the second most popular drug among teens in the US (Encarta, 1). Teens, ages 12-17, that use marijuana weekly are nine times more likely than non-users to experience with illegal drugs and alcohol (Fed. Study, 1). More 13 & 14 year olds are using drugs, fifteen pe...
At a high dose of 30 mg/kg. marked sedation and pronounced motor incoordination peaked at the one hour interval, subsiding in 8 hours when overreaction occurred to external stimuli; man reveals incapacitation of cognitive and motor function. High concentrations of marijuana are usually found in the following parts of the brain: the frontal cortex (the general association area), and hippocampus (short term memory and orientation). As a result, perception of time, mood and general coordination is impaired. It is apparent that marijuana intoxication affects the neurological functions and usually disappears in 24 hours, but can become a permanent malfunction.
Marijuana is a drug that is harmful to a person¡¯s health. It has been found to have adverse impacts on one¡¯s mental processes such as memory, attention, judgement, and problem- solving (Butcher, Mineka, Hooley, 2004, p.415). Also, marijuana can interfere with a person¡¯s ability to think rationally and logically. Thus, the lapse in judgement caused by the drug use can lead to risky sexual behaviours and this may result in increasing sexually transmitted disease such as AIDS. Moreover, the long-term use of marijuana may cause chronic breathing problems and cancer ...
Alcohol and marijuana use are common in adolescents. Studies have shown that 1 to 2 years of chronic marijuana use and 20 drinks per month show abnormal brain structure (Squeglia, Jacobs, & Tapert). Drugs or alcohol will make can c...
It has been long debated whether genetics or the environment in which one is raised impacts human psychological development the most. In Never Let Me Go, Kazuo Ishiguro shows that nurture cannot overcome one’s hereditary inclinations. Ishiguro exploits a world where human nature powerfully contradicts nurturing. He shows us that people, no matter how they were created or how they were raised, desire to be loved and accepted and need to know where they came from and what their future possibilities are.
When marijuana is used starting from early age it affects the brain development and its function. a) Use of the drug impairs memory, thinking and learning process by affecting connection between the neurons of the brain necessary for these functions. III. Marijuana use could also have a physical effect on the person. 1.
Marijuana while illegal on a federal level has been legalized in 18 states and the District of Columbia for medical use and also for personal use for anyone over 21 in Washington and Colorado. 48% of Americans admit to using marijuana according to a 2013 survey conducted by Scientific America. With the change in public opinion concerning marijuana the need to understand the effect and consequences associated with its use are vitally important. What are the effects on the brain and the rest of the body? Does it matter when you start using marijuana? Also what is the effect marijuana use has on a person’s life, to include school, work, family and friends.
Marijuana may control the way people act, think, and even hurt their college academics. Marijuana is one of the most popular used drugs in America ranking about third after tobacco and alcohol. Marijuana is a substance that has become very much a part of American culture; many college students have either used it occasionally or regularly. With that in mind, I thought it would be interesting to find out about students at Indiana University of Pennsylvania (IUP) and their use of marijuana. In fact most students might not even know what they are smoking and what exactly makes them feel the way they do.
The effect of Marijuana on American Society has been a highly popularized point of concern and discussion for many years. This topic has become more frequent in the past months as two states voters have allowed its widespread recreational and medicinal use. This research paper will focus on some of the history of marijuana, details of this drug, and conclude with my findings of why this drug has become increasingly popular which may surprise the reader.
The drug problem affects all types of students. All regions and all types of communities show high levels of drug use. Thirty percent of 1990 high school seniors in non-metropolitan areas reported illicit drug use in the previous year, while the rate for seniors in large metropolitan areas was 33 percent. Although higher proportions of males are involved in illicit drug use, especially heavy drug use, the gap between the sexes is closing Bibliography lists 4 sources. California has been considered a leader in the fight for drug control. With its 'three strike and you're out' program, the west coast state has demonstrated its firm stance on the issue of illegal drugs. However, the writer discusses that at the helm of this controversial topic is the mandate of minimum drug sentencing for what some consider to be insignificant usage; as such, people caught with what would have one time been considered a negligible amount of cocaine are now – under new and forceful laws – looking at a mandatory minimal jail sentence. An 8 page paper that argues against the legalization of marijuana from a sociological and psychological perspective. The writer suggests that while there is considerable data about the usefulness of this drug from a medical standpoint, the general legalization would have considerable social and psychological implications. A 6 page research paper that examines the effects of parental substance abuse on their children and argues that such abuse greatly increases the chances that their children will, likewise, develop substance abuse problems.
The marijuana affect the brain development, because the teenager are under go development still of age of 25. The effect of marijuana is immediately when is consume as smoke. The marijuana contain some chemical that affect the brain pressure, memory, thinking, concentration, movement, coordination, and sensory a time perception. All this affects the development of the brain and receptor, because is on constant development and every time that the teenager smokes the effect is immediately and this effect can be last for one to three hours. The concern about the use the marijuana is because affect the development of the brain and affect the intellectuality. According to National Institute of Drug Abuse, the overstimulation of these receptors on the brain areas produces the marijuana "high," as well as other effects on mental processes. In facts the used of mariju...
...ssures to be the best they can be academically. With all these pressures of adolescence on the rise, more and more teens are falling prey to the alluring “high” that allows a temporary leave from their problems and stress. Because teens lack the maturity and knowledge to understand long term consequences, they tend not to think about the down falls that they will face as a result of the drug use. This is especially true when it come to marijuana, as it is seen by so many as the harmless drug. With the increased use of marijuana by youth over the last three decades, it is imperative that better preventative measures, and firmer penalties, be put in place to educate and raise awareness concerning the risks and dangerous side effects that marijuana use can have. Only once society has put these preventative measures in to action, will there be an effective change seen.
Scientists have found that smoking marijuana can cause you to lose your memory. Marijuana has many psychological and physical effects. People usually smoke marijuana in cigarettes or pipes, but it can also be mixed with food and beverages. The short-term effects of marijuana include both psychological and physical reactions. These reactions usually last for three to five hours after a person has smoked marijuana.
Frontal Lobe Syndrome Although volumetrically the frontal lobes are the largest portion of the brain their function remains somewhat elusive (Jacobs, 2005). Even neuropsychologists have a difficult time creating test that accurately test frontal lobe functioning. We do know however, that the frontal lobes are involved in the storage of memories, concentration, abstract thought, judgment, and self control. The frontal lobe lies directly behind our forehead (NINDS, 2005)
Research philosophy, refers to the development of knowledge adopted by the researchers in their research (Saunders, Lewis and Thornhill, 2009). In other words, it is the theory that used to direct the researcher for conducting the procedure of research design, research strategy, questionnaire design and sampling (Malhotra, 2009). It is very important to have a clear understanding of the research philosophy so that we could examine the assumptions about the way we view the world, which are contained in the research philosophy we choose, knowing that whether they are appropriate or not (Saunders, Lewis and Thornhill, 2009). According to Saunders, Lewis and Thornhill (2009), three major ways of thinking about research philosophy are examined: ontology, epistemology and axiology. Each of them carries significant differences which will have an impact on the way we consider the research procedures. Ontology, “is concerned with nature of reality”, while epistemology “concerns what constitutes acceptable knowledge in a field of study and axiology “studies judgements about value” (Saunders, Lewis and Thornhill, 2009, p110, p112, p116). This study is intent on creating some “facts” from objective evaluations which are made by the subjects. Therefore, epistemology will be chosen for this study as the way of thinking about the research philosophy.
