Marijuana Damages the Mind and Body Essay

Marijuana creates many short-term and long-term effects on the body and brain. Some short-term effects include: impaired memory, altered senses, changes in mood, and difficulty with problem solving. Some long-term effects include: breathing problems, reduce memory, and decrease IQ. A study from New Zealand conducted in part by researchers at Duke University showed that people who started smoking marijuana heavily in their teens and had an ongoing marijuana use disorder lost an average of 8 IQ points between ages 13 and 38. The lost mental abilities didn't fully return in those who quit marijuana as adults (National). This study can be seen as reliable evidence because it was conducted by researched from Duke University, which is a private research

Marijuana has been used in the treatment of AIDS, cancer, glaucoma, multiple sclerosis, and chronic pain ("Medical Cannabis."). Researchers have been trying to explain the negative effects that marijuana can have on the central nervous system and how it hinders memory as well. The constant reports of short-term memory loss by heavy marijuana users brings up the question, is it the most common long term effect of marijuana use? Although it is said that marijuana has many effects such as exhaustion, increased appetite, offset sense of time, and bloodshot eyes, short-term memory loss is the symptom most frequently linked with the use or ingestion of marijuana. But why? Why does using marijuana have any impact on a person’s memory at all? Countless scientists have been working tirelessly to find an answer for this question. The active ingredient in marijuana, THC, is known to attach itself to areas of the brain linked to memory. When the scientists injected lab animals with THC at Rutgers University, they found that they acted as though there was no rhythm to their thought. It affected the hippocampal circuits in the brain to produce animals that were acting normal but in a delayed or offset manor.

The purpose of my paper is to prove that marijuana effects teens and their mind. Marijuana is a tobacco-like substance produced by drying the leaves, stems, flower tops of the Cannabis sativa (Indian Hemp) plant (Fact Sheet, 1). It is smoked or eaten to get hallucinated and receive pleasure. It grows just about anywhere. It is illegal in some countries but in others it is used for medical purposes (Encarta, 1). Some names that it is called a joint, nail, pot, Mary Jane, hive, etc. (Fact Sheet and Facts for teens, 1). Marijuana stays in the body for several days after one smoking session. In a chronic user marijuana can stay in the body for up to several weeks (Facts for Teens, 1).

Marijuana has its strongest long-term impact on young users whose brains are developing and maturing. Researchers see a decline in verbal ability as well as general knowledge in children between ages 9-12. (National Institute on Drug Abuse August

Millions are abusing marijuana every day. In fact, 1 out of 7 high school students smoke marijuana more than once a day. Marijuana is taken very lightly and is the most highly used illegal drug. For this reason, society should know its short and long term effects on the brain. Marijuana can effect these two areas emotionally or physically. Also in some cases physical damages causes the emotional response. Although most public information on drugs are funded by anti-drug organizations, hopefully we will still learn these true facts of marijuana in spite of that.

People might think smoking marijuana is cool. They might try it without knowing what it is or what affects is has on you. Once someone smokes it for the first time, they might keep doing it again and again and they could get hooked on it for life. People who use marijuana usually never use any other type of illegal drugs, but more than seven thousand five hundred people get arrested for using marijuana every year. There is a wide variety of marijuana, but they are all based off of two marijuana plants, Indica and Sativa. Marijuana is very popular in America, and all over the world. Marijuana affects the body, it can be used as medicine, and marijuana can be addictive.

Marijuana can have very damaging affects on a person?s brain. It can impair a person?s short-term memory, decision-making and signal detection (Cannabinoids). ?In one study conducted in Memphis, TN, researchers found that, of 150 reckless drivers who were tested for drugs at the arrest scene, 33 percent tested positive for marijuana? (Marijuana). After having used marijuana a

     Short-term memory is very important in our everyday lives. It is what allows people to remember many various things such as, phone numbers, directions to a friends house, and so on. Short-term memory impairment is fairly obvious with marijuana users. Many of the times users frequently forget the beginning of a conversation, or even the beginning of a sentence, but regularly they are still able to complete what they were saying without any knowledge of the topic (Tart, 2001). It is still unknown why this happens, but it is feasible that it relates back to the problem of too much information being processed faster then usual, allowing for distractions to take over the person’s mind, making them forget what they were originally talking about.

Marijuana continues to be the most widely used drug in the Western Hemisphere, its cognitive effects robustly revolve around memory. There have been many studies done on the chemical effects that marijuana has on the brain centers concerned with memory and learning. There are more productive studies relating to the effects of cannabis on short-term memory that show different memory processes effected by this drug. Though there is not much knowledge on the effects the drug has on long-term memory due to suspected confounds that temper with the process of collecting proper data, there have been studies showing lasting effects in adolescents and chronic users (Schoeler and Bhattacharyya, 2013). More research should be done on the long-term processes in order to better understand the lasting effects of cannabis use. Marijuana causes these adverse effects on memory by first altering chemical processes in the brain.

THC disrupts the nerve cells in the part of the brain where memories are formed. This makes it hard for the user to recall recent events (such as what happened a few minutes ago), and so it is hard to learn while high. A working short-term memory is required for learning and performing tasks that call for more than one or two steps. Some studies show that when people have smoked large amounts of marijuana for many years, the drug takes its toll on mental functions. Among a group of long-time heavy marijuana users in Costa Rica, researchers found that the people had great trouble when asked to recall a short list of words (a standard test of memory). People in that study group also found it very hard to focus their attention on the tests

Marijuana is considered in popular culture to be a widely accepted mainstream recreational illegal drug used in the United States; its use comes with severe adverse side effects that are often overlooked. Long-Term use of marijuana 'sis shown to have negative effects on physical, mental, and environmental health. Studies have shown that in the United States, up to 20% of daily marijuana users become dependent (Marijuana and Lung Health) showing a physical or emotional need for the drug. Marijuana use has the potential to affect every aspect of a person 's physical and mental wellbeing negatively. Its use also comes with potentially life-altering risks to one 's future including an individual’s likelihood of obtaining a degree, impacting their future earning potential and decreasing their overall reported life satisfaction. Once dependent on marijuana, people stop caring about their schooling. Long-term use of smoking marijuana can result in the inability to learn, retain information and think critically.

The article, “Marijuana and the Teen Brain”, from the Scientific American journal, Claudia Wallis, argues that marijuana negatively affects the teenage brain. Wallis begins her argument by stating her viewpoint on the drug and then proceeds to provide information to support her stance. Multiple studies by scientists/researchers are cited in this article including those based on x-rays of a marijuana user’s brain and others that tested marijuana users on their cognitive skills. Wallis additionally mentions a study on rats which tested the effects of THC. The author provides background information on marijuana to give the reader a better understanding of the concept. This source supports the argument that marijuana use has negative impacts on the human brain because the author also stands behind that argument. Wallis discusses these negative impacts and provides evidence to support her claim. This source cites various studies in which researchers tested the effects of marijuana on the brain which reinforces the argument that marijuana has abnormal effects on the human brain.

However, there is accumulating evidence of the psychological consequences of using marijuana. Many chronic marijuana smokers have a psychosis that is now medically deemed as, “A-motivational Syndrome” (Chopra 38). A psychosis is a condition where a person experiences some loss of contact with reality. A person with a psychosis can experience any or more of the following symptoms: auditory hallucinations (hearing voices that aren't really there), visual hallucinations (seeing things which aren't there), delusions (believing things that aren't true), jumbled thoughts and strange behavior. Patients with A-motivational Syndrome are left with the well-recognized and permanent symptoms of memory loss, apathy and loss of motivation (Chopra 38). After marijuana started to be widely used approximately 20 years ago, for permanent damage to occur it was felt by some that marijuana had to be heavily used over at least three years. However, there is accumulating evidence that smaller amounts will do damage. It is logical that to get the permanent “ A-motivational Syndrome”, small amounts of damage have to accumulate incrementally (Chopra 40). Although many marijuana connoisseurs of today may totally deny that that the use of this drug has lasting effects on the brain, research findings clearly indicate that long-term use of marijuana produces changes in the brain similar to those seen after long-term use of other major drugs of abuse (Erickson 89).

Marijuana, also known as Cannabis is the third most well-liked recreational drug, which only falls behind alcohol and tobacco, in the United States (The Whitehouse, n.d.). Marijuana is made up of dried leaves, plants, stalks, and pits from the hemp plant Cannabis Sativa, which comprises of the mind-altering compound delta-9-tetrahydrocannabinol (THC), in addition to other associated compounds. This plant substance can correspondingly be converged in a resin called hashish or an adhesive black fluid called hash oil. Efforts to legalize marijuana for medication treatment and recreational use in the United States have grown in current years. The Food and Drug Administration (FDA) states that marijuana may perhaps

Marijuana is a green or brown mix of preserved, crushed leaves from the marijuana plant. A psychoactive drug, marijuana contains fifty-percent more tar than tobacco. Smoking the harmful plant can damage the brain, lungs, and the male reproductive system and may escalate the effects of epilepsy and psychosis (Kahler, 1988). Within campus colleges and universities, there are a lot of students who are using marijuana recreationally. Long-term marijuana use can induce negative effects on short-term memory, concentration, attention span, motivation, and problem solving, which clearly interfere with learning. Tetrahydrocannabinol, the active ingredient in marijuana, can reinforce dependence on the drug and on other addictive drugs (Joffe &
