Essay on Marijuana Short and Long Term Effects on the Brain

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

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

Smoking of marijuana can cause the person to become addicted to cocaine, heroin, and other drugs. Heavy or daily use effects the parts that control memory, attention, and learning (Facts for Teens, 13). When teens are 12 and 13 they are more exposed to drugs and most likely don’t listen to their parents (Age in Stem., 1). Some other psychological side effects would be paranoia, anxiety, fatigue, Euphoria, and mood swings (Fact Sheet, 1). Studies have shown that when a person uses marijuana it causes the heart to beat faster and work harder (Fact Sheet, 2). When people have smoked large measures of marijuana for years, the drugs takes its charge on mental functions (Facts for Teens, 13).

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 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 does impair short-term memory, but only during intoxication. Although the authoritative studies on marijuana use seem to agree that there is no residual impairment following intoxication, persistent impairment of short-term memory has been noted in chronic marijuana smokers, up to 6 and 12 weeks following abstinence.

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).

People who smoke blow is acquainted with the "high" they feel when they smoke. This piece of writing debates the effects of THC on the brain, as well as the negative effects of heavy pot use on the mind.

The brain is very complex and allows us to do different things. The part of the brain known as the

Smoking marijuana is best described as a one-way ticket to negative side-affects. Based on Lifetime Health by Friedman, D. P., Stine, C. C., and Whaten S. “smoked marijuana are felt within minutes and may last for 2 or 3 hours”(2009). Short term effects consist of slowed thinking ability, difficulty paying attention, distorted sense of time, and many more. (Friedman, D. P., Stine, C. C., and Whaten S. (2009). Long term effects include frequent respiratory infection, impaired learning and memory, and even panic attacks (Friedman, D. P., Stine, C. C., and Whaten S. (2009). Thus, the ingestion in smoking marijuana can cause harmful outcomes, which are

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.

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.

     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.

The impact of marijuana on the brain and mind is far less dangerous or consequential than alcohols effects. There is very little evidence to ponder if any of the active ingredients in the plant allowed for human consumption have neurotoxic effects. Two types of receptors exist within the endocannabinoid system; CB1 receptors, and CB2 receptors. CB1 receptors are located in the brain and nervous system, while CB2 receptors are located in the immune system. Specifically in the case of seizures, “there is preliminary research which shows that the cannabinoid, cannabidiol or CBD, raises the threshold for seizure activity within the brain making it overall more difficult to have seizures, and thus providing hope to many parents of children with

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.
