Understanding Marijuana Use in Teens
Marijuana use among teenagers is a topic of concern due to its potential dangers and impact on their overall well-being. It is important to delve into the statistics on teen marijuana use and understand its impact on their developing brains.
Statistics on Teen Marijuana Use
In the United States, marijuana use among high school students is prevalent. According to the Centers for Disease Control and Prevention (CDC), in 2019, 37% of US high school students reported lifetime use of marijuana, and 22% reported use in the past 30 days. Additionally, a substantial number of middle and high school students reported past-year marijuana vaping, with 8% of eighth graders, 19% of 10th graders, and 22% of 12th graders engaging in this behavior.
Impact on Developing Teen Brains
The teenage years are a critical period of brain development, with the brain continuing to develop until around age 25. Marijuana use during adolescence and young adulthood may pose risks to the developing brain. According to the CDC, research suggests that marijuana use during this period may harm cognitive development, impair learning, and affect memory, attention, and problem-solving skills.
The long-term consequences of marijuana use on brain development in teens are still being studied. However, evidence suggests that regular marijuana use during this critical developmental stage may have lasting effects on cognitive abilities and brain structure.
Understanding the statistics on teen marijuana use and the potential impact on their developing brains is vital in raising awareness about the dangers associated with marijuana use during adolescence. By educating teens and their parents about the potential risks, we can work towards promoting healthier choices and safeguarding their well-being.
Academic and Social Effects
The use of marijuana among teens can have detrimental effects on their academic and social lives. In this section, we will explore the impact of marijuana use on educational attainment and the occupational and social implications for teens.
Educational Attainment and Marijuana Use
Research indicates that students who smoke marijuana tend to have poorer educational outcomes than their non-smoking peers. Adolescents who use marijuana regularly have a higher likelihood of developing drug dependence, attempting suicide, and engaging in criminal behavior [2]. The association between marijuana use and reduced educational attainment is evident, with regular users being significantly less likely to finish high school or obtain a degree.

Occupational and Social Implications
The consequences of marijuana use extend beyond educational attainment and impact the occupational and social lives of individuals. Heavy marijuana use has been linked to lower income levels, greater welfare dependence, higher rates of unemployment, and criminal behavior. Studies suggest that those who engage in heavy cannabis use are less likely to complete college and more likely to have household incomes below $30,000.
In addition to economic implications, heavy marijuana use can also lead to lower life satisfaction and negative perceptions of cognitive abilities, career achievements, social lives, and physical and mental health. These negative perceptions can impact self-esteem and hinder personal growth and development.

It is important to note that the effects of marijuana use on academic and social outcomes can have long-lasting consequences. Students who use marijuana more frequently during their first year of college are more likely to skip classes, resulting in lower grades. Increases in marijuana use frequency over time predict declines in GPA among college students, and baseline marijuana use frequency has an enduring effect on delaying graduation through its influence on skipping class and lower GPA at baseline.
Understanding the impact of marijuana use on academic and social aspects can help teenagers and their families make informed decisions and seek appropriate support when needed. It is essential to prioritize education, personal development, and overall well-being to ensure a successful and fulfilling future.
Workplace Consequences
The use of marijuana among teens can have significant consequences, extending beyond their personal lives and into the workplace. Understanding these risks is essential for employers and individuals alike.
Workplace Risks Associated with Marijuana Use
Employees who test positive for marijuana in pre-employment urine drug tests are found to have a significantly higher risk of industrial accidents, injuries, and absenteeism in the workplace compared to those who test negative for marijuana use. For example, according to the National Institute on Drug Abuse, postal workers who tested positive for marijuana had 55% more industrial accidents, 85% more injuries, and 75% greater absenteeism than those who tested negative.
It is crucial for employers to be aware of the potential risks associated with marijuana use among employees. These risks can impact productivity, safety, and overall workplace functioning. Implementing policies and procedures that address the use of marijuana in the workplace can help mitigate these risks and ensure a safe work environment for all employees.
Industrial Accidents and Absenteeism
Marijuana use has been linked to an increased risk of industrial accidents and injuries. Employees who use marijuana may experience impaired judgment, slower reaction times, and decreased coordination, which can contribute to accidents in the workplace. The National Institute on Drug Abuse highlights that individuals who test positive for marijuana are more likely to have higher rates of industrial accidents and injuries.
Moreover, marijuana use can also contribute to increased absenteeism in the workplace. Employees who use marijuana may be more likely to miss work or have higher rates of unexcused absences. This can disrupt workflow, decrease productivity, and strain the overall functioning of the organization.
Employers should prioritize creating a work environment that promotes the well-being and safety of all employees. This includes implementing drug testing policies, providing education on the risks of marijuana use, and offering resources for employees seeking support with substance use issues.
Understanding the workplace consequences of marijuana use among teens is crucial for employers and individuals alike. By addressing these risks, employers can help create a safer and more productive work environment, while individuals can make informed decisions about their own well-being and the impact of their choices on their professional lives.
Cognitive Effects of Marijuana
The use of marijuana among teenagers can have significant cognitive effects that impact their neurocognitive performance and brain development. It is important to understand these effects in order to recognize the potential dangers associated with marijuana use in this vulnerable population.
Neurocognitive Performance in Teen Users
Research has shown that heavy marijuana use among adolescents can lead to disadvantages in neurocognitive performance. Studies have found that adolescent cannabis users may experience subtle decreases in cognitive domains such as attention, memory, and processing speed. These cognitive impairments can have a negative impact on academic performance and overall cognitive functioning.
Brain Development and Function
The teenage brain is in a critical stage of development, continuing to develop until around the age of 25. Marijuana use during adolescence and young adulthood may harm the developing brain [1]. Research has indicated that adolescents who engage in heavy marijuana use often show alterations in brain development and functioning.
One aspect of brain development affected by marijuana use is the macrostructural and microstructural changes in the brain. Adolescent marijuana users have been found to have decreases in cortical volume and changes in cortical gyrification, which may impact brain function. Additionally, white matter integrity, as measured by quantities like fractional anisotropy and mean diffusivity, is often poorer in adolescent marijuana users compared to non-substance-using controls [4]. These alterations in brain structure and function can have long-term implications for cognitive abilities and overall brain health.
Understanding the cognitive effects of marijuana on teenagers is crucial for promoting awareness and prevention. By recognizing the potential risks associated with marijuana use during this critical developmental stage, we can better support and protect the cognitive well-being of teenagers.
Mental Health Risks
The relationship between marijuana use and mental health in teenagers is an area of concern that has garnered significant attention. Research has shown an increased risk of psychiatric disorders, including depression and suicidality, in individuals who use cannabis during adolescence. Understanding the potential mental health risks associated with marijuana use is crucial in order to protect the well-being of teenagers.
Association with Psychiatric Disorders
Numerous studies have highlighted a link between marijuana use and psychiatric disorders. Research indicates that marijuana is increasingly associated with conditions such as depression, bipolar disorder, and schizophrenia, particularly in young men. Adolescents who use cannabis recreationally are two to four times more likely to develop psychiatric disorders compared to those who do not use cannabis at all. The relationship between cannabis use and psychiatric disorders is complex and influenced by various factors, including the amount and frequency of drug consumed, potency, type of cannabis product, and age at first use. Further research is needed to fully understand the extent to which cannabis contributes to poor mental health outcomes.
Increased Risk of Depression and Suicidality
Marijuana use in teenagers has been associated with an increased risk of depression and suicidality. Research has shown that individuals who use cannabis during adolescence are more likely to experience depressive symptoms and have a higher risk of developing depression later in life. A study led by researchers from Columbia University found that teenagers who use cannabis recreationally are at a higher risk of developing psychiatric disorders, including depression and suicidality, compared to those who do not use cannabis at all.
It is important to recognize that the relationship between marijuana use and mental health outcomes is influenced by various factors, including genetic predisposition, environmental factors, and the age at which individuals begin using marijuana. Adolescents and young adults are particularly vulnerable to the effects of cannabis as their brains continue to develop until the mid-to-late 20s. Using cannabis before the age of 26 has been found to increase the likelihood of addiction and the development of mental disorders, while waiting until at least age 26 reduces these risks.
Understanding the potential mental health risks associated with marijuana use in teenagers is crucial for parents, educators, and healthcare professionals. By being aware of these risks, appropriate preventive measures and interventions can be implemented to mitigate the potential harm to young individuals.
Long-Term Effects on Brain
When it comes to the relationship between marijuana and teens, it is crucial to consider the potential long-term effects on the developing brain. Two key areas of concern are the decline in IQ and cognitive impairment, as well as structural changes in the brain.
IQ Decline and Cognitive Impairment
Persistent marijuana use during adolescence has been associated with a decline in IQ, particularly when it progresses to cannabis use disorder into adulthood. A large longitudinal study conducted in New Zealand found that individuals who heavily used marijuana as teenagers and later stopped did not recover the lost IQ points, while those who started using heavily in adulthood did not experience a decline in IQ. On average, persistent marijuana use disorder with frequent use starting in adolescence has been associated with a loss of 6 to 8 IQ points measured in mid-adulthood.
In addition to IQ decline, chronic THC (the main psychoactive component in marijuana) exposure may contribute to cognitive impairment. Research on rats exposed to THC daily for 8 months showed nerve cell loss in the hippocampus, a brain region crucial for learning and memory, at an age equivalent to unexposed animals twice their age [7]. These findings suggest that chronic THC exposure during adolescence may expedite age-related loss of neurons in the hippocampus, leading to a decreased ability to learn new information.
Structural Changes in the Brain
Studies have also revealed that marijuana use during adolescence can result in structural changes in the brain. THC exposure during adolescence in rats has been linked to cognitive impairments, including altered reward systems and learning/memory problems later in life. These impairments are associated with structural and functional changes in the hippocampus, a brain region involved in memory and spatial navigation.
It is important to note that the age of onset, amount, and duration of marijuana use can influence the degree of cognitive impairment. A study tracking nearly 4,000 young adults over 25 years found that cumulative lifetime exposure to marijuana was associated with lower scores in verbal memory tests, even after controlling for various factors such as current use, demographics, other substance use, and psychiatric conditions.
Understanding the potential long-term effects on the brain is crucial for individuals, particularly teenagers, who may consider using marijuana. These findings emphasize the importance of promoting informed decision-making and providing education about the risks associated with marijuana use during adolescence.
