Functional Consequences of Marijuana Use in Adolescents: A Critique of Jacobus, Bava, Cohen-Zion, Mahmood, and Tapert (2009)
ABSTRACT:
Functional Consequences of Marijuana Use in Adolescents: A critical review of Jacobus, Bava, Cohen-Zion, Mahmood, and Tapert (2009) addresses the question of how does the use of marijuana affect an adolescent’s brain functioning, structure and sleep. The article assesses many other studies and literatures in order to summarize the conclusions respective to these affects of marijuana use. Through careful review of these studies, the authors were able to determine the affects on an adolescent’s brain functioning, structure and sleep. The results which are presented dictate that Adolescents who use marijuana have a disadvantaged in their processing speed of attention and learning depicted through some subtle abnormalities in the brain structure. Consequently, adolescents with have prolonged marijuana use generally require more brain processing to complete tasks. In addition to the above, marijuana use in adolescents also affects their ability to sleep. In conclusion, research shows that some abnormalities associated with marijuana use continue after a month of stopping the use of marijuana, but many abnormalities may stop after 3 months of quitting. In this
There has been an extensive amount of research done on risk factors and marijuana use. Among adolescents the vast majority of the research has identified five major risk factors associated with adolescent marijuana use, family relations (parent-child attachment), peer associations, substance abuse programs, gender, and race. Some researchers have found that the family is the best predictor of adolescent marijuana use, while others claim that peer associations are predictors of adolescent marijuana use. Others believe that substance abuse programs are the key to deterring adolescent drug use. The final groups of researchers believe gender and race are the underlining predictors. The following studies will give a quick overview of the prior research on risk factors and adolescent marijuana use.
What is Marijuana? The marijuana affects the brain development on teenager. Also affect the function at school, work, and social life of the teenagers. The marijuana increases the risk of mental health issues. The sadistic show that the used of marijuana increase every years. Marijuana affects the teenager and also their families.
Research has found that teenagers who used cigarettes were twelve times more likely to graduate to marijuana use. A similar study conducted by Denise Kandel (1992) revealed that use of marijuana affects dopamine levels in the brain in a similar way to nicotine. Cigarette smoking facilitates consumption of other substances. Smoking cigarettes initiate juveniles into the sensation of drug inhalation, which desensitizes them from the feeling of smoke clouding their lungs. This paper finds that marijuana pervades the life of a juvenile tobacco smoker. Teenagers who smoke cigarettes
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).
In this article, whether or not prenatal marijuana exposure (PME) contributes to marijuana use at age fourteen is studied. Over the years the use of marijuana and its effects on adolescents has increased. There have been attempts to prevent the use of marijuana among adolescents, but in order to prevent something you have to know the reason for the occurrence. “Among preteens and adolescents, PME predicted poorer performance on tests of memory, attention, and executive functioning” (Day, Goldschmidt & Thomas, 2006). In addition to PME, factors such as: child management practices,
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
Marijuana addiction can negatively impact our children’s minds, body, relationships to others and future opportunities. Thus, their wellbeing and ability to function normally are obstructed by inducing mental aggressions and fatigue due to sleep deprivation. Teenagers choose to smoke marijuana out of sheer curiosity, peer pressure and the desire to fit in with friends. Adolescents have the perception that marijuana can help them to cope with anxiety, boredom, anger issues or unpleasant feelings
Dr. Vokow, Director of the National Institute on Drug Abuse, has also found that long term use of marijuana can affect the IQ of adolescent children in which they never recover (3). Furthermore, young people can also suffer from anxiety; depression; even thoughts of suicide.
Marijuana is one of the most commonly used drugs in the Nation and the world. In an article by Gray (2007) he states that “42% of high school seniors have tried marijuana, 18% have used it in the past 30 days, and 5% use it daily. Among adolescents aged 12 to 17, 3.6% met criteria for cannabis use disorder (abuse or dependence) and 2% met criteria for cannabis dependence”. Gray (2007) also explains how easily adolescents say it is to obtain marijuana these days. The article also states that there is evidence to prove that marijuana use may lead to “hard” drug use, academic failure, and more. With those who use marijuana chronically it may lead to impairing of the immune
The University of Michigan “annually survey in 2010 ” identified that adolescents nationwide, will start using drugs from 8, 10, and 12-grade use drugs, which include alcohol, Tabaco, marijuana, and other drugs; the survey shows the increased of marijuana use among high school seniors to daily basis. Consumption is the highest in comparison with the previous study nearly 65% of those students use marijuana as their primary drug of choice.
One of the biggest issues since legalization of marijuana in Colorado is the effect it has on our youth and future generations. In a report posted regarding the cause and effect on teenagers using marijuana Krista Lisdahl, director of the Brain Imaging and Neuropsychology lab at University of Wisconsin, Milwaukee, talks about the changes in the THC levels from the seventies to now. She also talks about how through modern technology it is possible to physically see the difference in the brain when a teenager is
Some users of marijuana have later been diagnosed with psychosis or schizophrenia. There is currently sufficient evidence to conclude that those who start using marijuana at an earlier age, have a higher risk of developing psychotic behaviour such as schizophrenia (Timms, Dr. Phillip). A study that was conducted with 1,600 Australian students aged around fourteen-fifteen, in which these students were watched closely for about seven years, found that those children who used marijuana regularly are at a higher risk for depression (Timms, Dr. Phillip). In fact, it was noted that adolescents who have used marijuana regularly were five times more likely to develop depression and anxiety into their adulthood (Timms, Dr. Phillip). There are many cases that link the use of marijuana to the increased chance of forming mental illnesses. Marijuana mentally shuts down a person time after time without even realizing the effects yourself.
It seems every decade marijuana studies show that it has no side effects on users, in turn it become more available like when some states in America had legalized it. Dr Kevin M. Gray believes that the only side effect of smoking weed is the physical addictions it causes, he believes that over 51% of all teens have used weed at least once and the biggest problem we are facing with this rapidly growing drug use is only addiction. Dr Marshall M. Gay believes that the health effects of weed isn’t that much as smoking cigarettes and doesn’t see it a threat to people’s health. “More than half (51%) of adolescents reported that marijuana is fairly or very easy to obtain.2 this ease of availability may have contributed to a recently reported "reverse gateway" from cigarettes use to marijuana”. The more ignored belief is that marijuana can lead to a variety of developmental, mental and physical side effects. The effects of smoking weed can extend to those of smoking cigarettes “studies show regular marijuana use can lead to many of the same
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.
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 &
