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.

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

Many researches are educating pregnant women about the danger of cigarettes, alcohol and the potential negative effects of cigarettes, alcohol on fetus development. However, scarce research directly addresses specific effects of marijuana on pregnant women because women who use marijuana also tend to smoke cigarettes, drink alcohol and more likely to use other drugs such as cocaine and heroin. Thus, it is difficult to identify the precise effects of marijuana on pregnant women and on a fetus (Leemaqz, 2016.). Marijuana is the most commonly used illicit drug in the United State (Murray & McKinney, 2014). According to the American College of Obstetricians and Gynecologists, 40-60% of marijuana users continue to use during pregnancy. Studies have also shown that marijuana crosses the placenta negatively affecting brain development, and increasing the risk of pre-term birth. Proposition 64, the California Marijuana Legalization Initiative for adult use just passed after the election, California is added into the list of 26 states legalizing marijuana for medical or recreational purpose which could increase the number of women using marijuana during pregnancy. Due to above evidences, doctors warn pregnant women, women planning to pregnancy and breastfeeding women that they should discontinue their use of marijuana and should consider alternative therapy.

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 is the most popular illicit drug used among our teenagers in the United States. Research shows that 42% of high school seniors have smoked Cannabis, 18% within the past month and 5% smoked daily and 1 in 6 are addicts. More than 64% of teenagers reported that marijuana is very easily available (Gary). Unfortunately, some parents live in a world of denial and say “It’s not my kid. My child doesn’t smoke.” Unbeknown to us, there are unfavorable concerns for many young marijuana abusers such as the risk of addiction, poor school performances and a “gateway” to other lethal substances. Smoking marijuana increases respiratory diseases, impaired immune function, cognitive problems and motivational impairment. (National Institute on Drug Abuse). It is the leading cause of abnormal cognitive development which persists long after abstinence. Marijuana is the main drug used by children who seek emergency medical treatments and screened following an arrest or autopsies (Dennis et at).

I am very concerned about the legalization of marijuana, since I am a parent of six children, whose ages range from nine to twenty-two. I have made it a point to educate my children on how smoking marijuana can affect their brain development. Just recently my youngest son, has told me that he has learned that middle school and high school kids have been eating marijuana in different forms of baked foods, such as brownies, chocolate truffles and rice crispies. The kids are over eating the marijuana treats because they don’t think it’s getting them “high”. The children are not realizing that it takes time for the body to absorb the THC. They then end up in the hospital for feeling ill because they have eating too much of the drug. The National Families in Action Campaign, reported that pot-related emergency admissions have tripled and expulsion rate has gone up 40% since the legalization of medical marijuana due to pot related incidents (5). Parents will need to be more aware of the potential risks and signs of THC posing due to the high levels of THC found in the marijuana that

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 physical effects of marijuana use, particularly on developing adolescents, can be acute. The emotional development of adolescent users may be interrupted. Scientists feel heavy doses during adolescent damages emotional and intellectual development a

Within Friese and Grube, they state that Marijuana is the most commonly used drug among teens in the US and with the access to medical marijuana, teens have only increased their use (34). Research also argues that with legalization, recreational use would suggest to adolescents that marijuana is safe and normal (Friese and Grube 34). This finding suggests teen use might increase (Friese and Grube 34). Therefore, since research shows a defeat in executive functioning and processing with use of cannabis (Battistella et al.), it is essential that adolescences decrease their use since the teen brain is still maturing (Crean et al. 5). As well, there is evidence that teenagers who use cannabis in early years have more significant cognitive problems than their peers (Crean et al. 2). Furthermore, in Friese and Grube findings, they argue that a typical drug free environment is crucial for teens’ development (37) since an environment with accessible marijuana will encourage marijuana use and increase risks of negative consequences in their adulthood and health (Friese and Grube 33). Therefore, legalizing the recreational use of cannabis could potentially have a large harmful effect on

Marijuana in the late 1960s’ had only one percent of tetrahydrocannabinol, compared to present day where Health Canada has discovered there is at least 10 percent of tetrahydrocannabinol and 30 percent in some cases. The tetrahydrocannabinol is a strong chemical and works immediately after one has inhaled it. Tetrahydrocannabinol mimics the neurotransmitter anandamide, which fills in the synapse between neurons and this disrupts the brain’s regular functions. In a normally functioning brain, anandamide activates the cannabinoid receptors but when smoking marijuana tetrahydrocannabinol activates these receptors which are in the hippocampus, cerebellum and basal ganglia. This affects the short-term memory, coordination, and learning and problem-solving skills for an individual. Brain development is also affected by the use of cannabis. Dr. Harold Kalant conducted a study in the 1980s’ with rats and cannabis use. He separated the rats into two groups; rats exposed to cannabis at adolescents and rats exposed to cannabis in adulthood. Kalant observed the rats exposed to cannabis as adolescents, had difficulty with memory and learning even after nine years of no exposure. In comparison, the rats who were adults when exposed to cannabis didn’t have long term effects. It is evident that brain development was disrupted by the use of cannabis in the growing years. Also, Dr. Andra Smith saw in her functional magnetic resonance imaging of brain activity of regular cannabis smokers and non-smokers, that the smokers had a more brain activity. She stated it was due to the brain having to work hard to “respond accurately”. It is obvious that brain function and development is harshly impacted by the use of

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

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

First, recreational marijuana is harmful to the brains of young people. Infants and children still unborn can be harmed if their mother uses marijuana. Some women declare they use marijuana for morning sickness or other uses while pregnant. Brain impairment to the infant is the main problem associated with marijuana while pregnant (USA Today “Marijuana Health Risks”). Young people aren’t only children and infants, but also teenagers. Teenagers who use marijuana can have a significant IQ decline as they age. For example, a study indicated that individuals who began smoking marijuana heavily while teenagers and had an ongoing marijuana use disorder lost an average of eight IQ points between ages 13

Many children and teens are very mature to say “no” for using cannabis in the wrong ways, for example in Colorado teenagers stubbornly refuse to smoke cannabis. Jacob Sullum points out “…the percentage of Colorado high schools reporting having consumed marijuana within the past 30 days fell from 22 percent in 2011 to 20 percent in 2013.”(Marijuana Re-Legalization: Its effects on teens) This report shows that not every teenager or child is automatically going to use them for the wrong ways. The study concludes that “legalizing medical marijuana has not increased teen pot

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.
