In this article, Kristen Weir reviews the effects marijuana has on the developing brain. As more states are now legalizing marijuana for not only medical but recreational use, many medical doctors and psychologist fear the long-term effects. Many of marijuana’s long-term effects are still unknown even though it is one of the most widely used illegal substance in the United States. Recreational use in states that marijuana is legalized in only pertains to citizens 21 or older. Even with the age restrictions, some doctors still fear the legalization of marijuana recreational will allow the drug to become more accessible to younger adults or adolescences. Susan Weiss, the director of the division of extramural research at the National Institute on Drug Abuse (NIDA), voiced her concerns on the topic stating, “There are a lot of open questions…. But there 's a growing literature, and it 's all pointing in the same direction: Starting young and using frequently may disrupt brain development." (Weiss). As she acknowledges the fact that there is a “growing literature” when it comes to marijuana use and its effects, she also admits the new research is all leading to the same conclusion, frequent use and starting young may disrupt normal brain development. The government and other private institutions are funding and researching these unknown effects.
Medically, marijuana has proven to be a productive drug. Studies show marijuana has helped dealing with “pain, muscle spasms, seizure disorders and nausea from cancer chemotherapy.” (Weir) Scientist believes these benefits come from a chemical compound in marijuana called cannabidiol. This chemical is not the active chemical that gives marijuana users the mind-altering effects. With the unce...

...eveloping parts, the frontal cortex, is responsible for planning, judgment, decision-making and personality. Teenagers also have to deal with the immaturity of their endocannabinoid system. This system is accountable for the psychological mechanisms that respond to the active drug in marijuana, THC. Krista Lisdahl, PhD, the director of the Brain Imaging and Neuropsychological Laboratory at the University of Wisconsin, Milwaukee, states, “That system (endocannabinoid) is important for cognition, neurodevelopment, stress response and emotional control, and it helps to modulate other major neurotransmitter systems” (Lisdahl). Frequent exposure to marijuana can “dial down cellular activity in the endocannabinoid system… That sets the stage for why adolescents may be more sensitive to the effects of repeated marijuana exposure, from a neuroscience perspective." (Lisdahl)
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.
The article discussed several potential health benefits to medical cannabis. For example, medical marijuana can be used to test glaucoma by slowing the progression of the disease and preventing blindness. It can help control epileptic seizures and decrease the symptoms of a severe seizure disorder known as Dravet’s Syndrome. The chemical CBD may help prevent cancer from spreading. In addition, it may decrease anxiety, ease the pain from multiple sclerosis, and slow the progression of Alzheimer’s disease. Medical marijuana may lessen the side effects from treating some illnesses such as hepatitis C. It has also been used to alleviate pain, reduce inflammation, and promote
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 is a unique and controversial drug. It is a popular psychoactive drug that is easily accessible and relatively inexpensive. Marijuana is often considered a recreational drug despite its illegal status. It is illegal because there are many uncertainties surrounding this substance. In fact, some favor the use of marijuana for medicinal purposes while others oppose. Opponents of marijuana insist that legal approval will result in serious personal and social problems.
After smoking, or consuming marijuana, it is distributed in the brain. The concentration of marijuana in the brain may be governed by an active transport process in the choroid plexus network of blood vessels in the brain which regulates intraventricular pressure by absorption and secretion of cerebro spinal fluid. one scientific experiment it gave an example of how the distribution of marijuana in the central nervous system could effect man. 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 over reaction 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 oreintation). As a result, perception of time, mood and general cordination is impaired. It is apparent that marijuana intoxication effects the neurological functions and usually disappears in 24 hours, but can become a permanent malfunction.THC effec...
...o treat many conditions; an ancient Chinese emperor prescribed it to cure conditions such as gout and malaria, soon its healing properties were heard around the world and the use of cannabis as a medicine spread like wild fire to many other regions (Earleywine, p. 168). In fact marijuana was legal in the United States till 1942 when against the medical communities recommendation it was removed from the list of acceptable medications. Today there are numerous studies being conducted on the effects of medical marijuana and scientists have proven its effects on treating many symptoms. According to Dale H. Gieringer in his book Medical Marijuana Handbook he states, Marijuana is proven to be effective as an anti-nauseant and an appetite stimulant for people going through chemotherapy and as an analgesic for patients suffering from chronic pain (Gieringer, p. 39).
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.
Many could argue that marijuana is destructive physically as well as mentally. “The National Institute on Drug Abuse says marijuana can cause heart irregularities, lung problems, and addiction” (Welch). “One joint can be just as damaging to [the lungs] as smoking at least two and a half cigarettes” (Ruff). According to Dr. Tom Wright, director of a substance abuse treatment center for adolescents in Rockford, “teens may be especially sensitive to marijuana’s effects because their brains are still being formed” (MJ Rebuttal). However, the marijuana legalization proposition would have tight restrictions and regulations by the states that would eliminate some of those issues, such as age. These facts are not consistent; the evidence is not backed from reliable sources. One institute is referred to, but more experts are needed to verify the information.
The Effects of Marijuana Marijuana is a mood altering or psychoactive drug that has many nicknames, such as pot, weed, ganja, sensi, herb, and. others. The. It is an ancient drug that dates back to hundreds of years to the Asia. Many cultures have used it during meditation, religious.
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...
Marijuana has many bad side effects that harm the body. According to Szara Braude, marijuana slows down reactions causing problems with memory and learning, distorted perception, difficulty in thinking, and loss of coordination (Marijuana as a medicine 53). Many people use this drug not knowing wh...
The use of drugs and mind-alternating substances has been a part of society for decades. The ‘high’ that people attain from the use of such substances is very attractive and exciting however, the effects of this use are minimized. Particularly for youth, a group of individuals who are seeking independence and experimentation, drug use represents the balance between taking risks and taking responsibility for one’s actions. However, the developmental processes of adolescents are known to not encompass the maturity required to fully think through such decisions. As such, the use of a ‘smaller-scale’ drug like marijuana is even more minimized. The purpose of this paper is to discuss what the risks of using marijuana are for youths, why they are the most affected, how this problem has progressed over the last three decades, and what preventative measures and treatment options are in place. It will also discuss what schools, parents, and government agencies could be doing to help improve the issue, and the impact that this issue is having on society.
There has always been controversy about marijuana and the affects it has on health and the issue of legalization. Some people believe it is very destructive to one’s health, and yet others feel the complete opposite about it. Is Marijuana truly harmful to one’s health? “Marijuana, the Deceptive Drug”, written by George Bierson, was published in the Massachusetts News. In this article, Bierson determines that marijuana is harmful in many ways. He seems to think that it damages the brain, the reproductive system, and also contributes to the halt of production in the immune system. Bierson also tries to persuade the reader that marijuana is a “gateway drug” that leads to larger drugs in the future. However, by conducting research of my own, I have come to the conclusion that Bierson’s article simply lacks truth.
Marijuana and alcohol use have been thought to be detrimental to brain function. The purpose of this experiment was to observe, and test, what kind of effects marijuana and alcohol have on the brain. This experiment is a longitudinal study that consisted of the participants using alcohol and marijuana over a period of three years and being evaluated by a series of tests. These tests measured multiple aspects of cognition such as memory and how quickly they could understand and sort material. The partakers were chosen from students in California whose ages ranged from 16-19 years old, therefore these students are in late adolescence and early emerging adulthood. It is important to note these stages because the use of drugs can alter the brain
