The Effects Of Marijuana On The Brain

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.

Humans’ brain doesn’t stop developing until they reach the age of 25 years. Therefore, there are many implications that can affect the brain cell while in the process of growing, including the use of drugs. Today’s adolescents are taking marijuana as a way to experience the greatness of “chill life.” However, they are not aware of how much it is impacting their lives.

Marijuana is known for causing issues with the human brain, which is a product of behavioral issues. Nevertheless, being under the influence of this drug can produce poor memory and little to no attention span (Marijuana: A Continuing Concern). Research shows that all of these effects can indeed take place after using the drug. After long term use of marijuana, the human brain may not become fully developed if the user started the drug at a young age. This could result in the brain not reaching its full potential. Furthermore, it is acknowledged that someone can have complications with their short-term memory after using the drug, and these complications can last for a multitude of days. People who are under the influence of marijuana have a difficult time paying attention to what is going on around them. With the use of marijuana comes brain damage, which some could become permanent (Marijuana: Breaking Down

Marijuana has linked to, lack of motivation, anxiety, reduced sexual capacity, confusion, mood changes, and schizophrenia-like brain changes, however all of these effects have not been proven. A study in 1999 concluded that heavy-users of marijuana over a 15 year period had not had any negative impacts on the users intelligence. (Armentano) These facts combined together show that both drugs have an effect on the brain but neither worse than they other.

The effects of marijuana have been examined in several studies that focused on long-term structural differences, cognitive impairments, prenatal risks and neural functioning deficits. Long-term structural abnormalities include reductions in the volume of the hippocampus, amygdala and nucleus accumbens, where these structures also exhibited changes in density and shape. Participants in several studies showed impairment in memory, learning, concentration, coordination, as well as decreased motivation. Marijuana has addictive properties and has dramatically increased in potency over the last decade, which has led to an increase in marijuana-related fatal car accidents and to an increase in emergency room visits. On the contrary, the non-psychoactive

60 of over 400 identified chemicals found in cannabis are called cannabinoids, including THC; the cause of the high. The cannabinoids attack natural cannabinoid receptors in the brain, causing lack of coordination, hyperawareness of sound, visual and audio distortions, lack of sense of time, and more. The overload of sensory regions disrupts the development of neural pathways. Teen brains are still trying to make connections and wire itself together, and this interference of normal brain function damages the hippocampus, amygdala, cerebellum, and other major parts of the brain. The list of possible effects of substance abuse is long and still growing; damage to behavioral function, attention deficit, depression, emotional damage, memory problems, lack of motor skills, poor visual/ spacial awareness, reduction of goal-directed behavior, hyperactive disorder, lower IQ, and

Along with the negative effects marijuana has on the lungs, it also has many negative effects on the brain. Smoking marijuana causes negative effects on attention span, memory, and learning; which can last for days and even weeks after the acute effects of marijuana wear off.(“Marijuana Abuse”). Many people believe that attention span, memory, and learning are not import when they smoke marijuana. Attention span, memory, and learning are all very important in everyday life, school, and work. “THC (tetrahydocannabinol) produces

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 over stimulates the parts of the brain that contain the highest number of receptors and can also affect the way the brain develops. When people use marijuana they can potentially impair their thinking, memory, and learning functions that can in turn affect how their brain

Does marijuana create an altered state of consciousness, or does it simply allow users to interpret more information at a quicker speed giving us the illusion of being "stoned"? For many years people of all ages have been using marijuana mainly for recreational purposes, not knowing that it increases their senses and perhaps even helps cure or prevent disease. After many carefully constructed experiments, it is now accepted by several scientists around the world that marijuana effects the human body as a whole, thus creating an altered state of consciousness.

According to research, smoking marijuana daily can affect the development of the brain and can assure long term effects. A person’s memory can be impaired from marijuana because THC(tetrahydrocannabinol) changes how information is processed in the hippocampus. With the THC, people who smoke may experience a loss of hippocampal neurons, which are used to help them learn new information, and with the loss of those neurons plus the loss of neurons as they age, the person is not able to learn new information as quickly as others around their age. This affects society’s future by lowering people’s intelligence

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.

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.

One of the biggest reasons non medical users smoke marijuana is for “Stoned thinking” . “Stoned thinking” is a term used to describe the way they think while high. “Stoned thinking is believed to lead to a new “level” of thinking, such as instead of looking at the ways things are different but how they are the same (Caulkins,2012). While there are not many trials explaining as to why however marijuana has also shown to help with athleticism. Some may wonder how marijuana could help an athlete, but marijuana must be banned from sports for a reason that reason being that it is believed to calm an athlete's nerves and anxiety (Caulkins,2012). Marijuana is also believed to lead towards a more creative life, while that may be connected to “ Stoned thinking” it makes an artist's life much easier. The last benefit is easily arguable to be seen as not a benefit but for the sake of this paper it is, that benefit being pleasure
