The stereotypical image of a cannabis smoker is someone who sprawls on the sofa for hours surrounded by a haze of smoke and half-eaten snacks.

The scene is played up for laughs in films, but social psychologist Angela Bryan thought it could be cause for concern.

After all, cannabis is known to increase appetite and aid relaxation, which might put people at risk of health conditions such as obesity, says Bryan, who is at the University of Colorado Boulder.

Part of Nature Outlook: Cannabis

But digging into health trends revealed the opposite. Nationwide US studies report that, compared to non-users, cannabis users actually have a lower prevalence of obesity1. Intrigued, she began to investigate.

Earlier this year, her team surveyed more than 600 cannabis users living in US states where the drug is legal about their exercise habits, among other health factors2. Four five respondents said that they use marijuana right before or after exercising.

And those users spent more minutes per week exercising than users who didn’t mix the two. “We were shocked,” Bryan says.

Her findings and those of others suggest that using cannabis before or after working out could be common. But scientists know very little about the effects cannabis could have on exercise.

A handful of studies were conducted decades ago, but since then laboratories in the United States have found it difficult to run controlled cannabis studies because of federal restrictions.

Instead, researchers are turning to surveys and anecdotal reports to piece together the biological mechanisms by which cannabis might affect physical activity.

A survey says

In Bryan’s survey, about 70% of respondents who used cannabis before working out said doing so made exercising more enjoyable. People who use cannabis might say that taking the drug makes any activity more fun, but Bryan suggests that in the case of exercise there are specific chemical interactions at play.

Consider a runner’s high, the feeling of euphoria that kicks in when some people reach a sweet spot in their workout.

The experience has been attributed to the release of chemicals in the brain called endorphins, but solid evidence of this is wanting. For instance, endorphins are thought to give a pleasurable feeling because they activate opioid receptors.

But researchers have found that people who take opioid-blocking drugs before exercising can still achieve states of bliss during a workout3.

An alternative suggestion is that exercise-induced euphoria originates in the endocannabinoid system.

A 2003 study4 found elevated levels of the endocannabinoid molecule anandamide in the blood of volunteers after they ran or cycled in a lab.

Because cannabis targets these same endocannabinoid receptors, Bryan speculates that the drug might allow users to “jumpstart” those pleasurable feelings.

She stresses that direct evidence connecting cannabis to runner’s high remains to be found. But nevertheless, she says, people say they enjoy exercise with cannabis, which could create a positive feedback loop that motivates them to go back to the gym. “If something feels good,” she says, “you’re going to want to do it again.”

Another way in which cannabis could encourage exercise is by aiding recovery, Bryan says. In her survey, 77% of people who use cannabis alongside exercise said that it helps with recovery. Again, researchers haven’t done controlled studies looking at cannabis and recovery. So, for now, Bryan says, “we have to kind of guess the mechanisms that we know.”

What researchers do know is that intense physical activity puts stress on the body. It triggers a flood of chemicals known as cytokines, some of which inflame muscles, that manifests as soreness the next day. Cannabis might modulate this inflammation — but potentially in multiple conflicting ways.

Bryan explains that although cannabidiol (CBD), a non-psychoactive component of cannabis, has been shown to suppress pro-inflammatory cytokines, the psychoactive part, tetrahydrocannabinol (THC), stimulates both pro- and anti-inflammatory cytokines. In other words, CBD could limit the feeling of sore muscles, whereas THC could help to both prevent and trigger the discomfort.

Some studies suggest that THC can also help to manage pain5, which might also boost recovery, she says.

Bryan’s team found that the survey respondents who used cannabis alongside exercise tended to be younger and male. Meanwhile, a survey, the results of which are unpublished, conducted on social media by Humboldt State University in Arcata, California, which targeted people who use cannabis with exercise, had roughly an equal number of male and female participants.

Led by Whitney Ogle, a physical therapist and cannabis researcher at Humboldt, the survey of 126 people uncovered cannabis use before all sorts of physical activity — 55 activities in total, ranging from archery to waterskiing.

Aside from sheer enjoyment, people in the Humboldt survey reported numerous other benefits of combining cannabis with exercise.

They thought that cannabis increased their focus, concentration and mind–body awareness — something that elite athletes have also reported6, although scientists have yet to come up with possible mechanisms for these effects.

Ogle’s survey also asked participants something the Colorado team’s survey did not: did people have negative experiences after combining cannabis and exercise? About 40% of respondents reported adverse effects, which included elevated heart rate and being too high to continue with their workout, Ogle says.

The biggest limitation of the survey by the Colorado team, Bryan says, is that it didn’t include a non-user control group.

The researchers polled people from states such as Colorado, California and Washington, which already have higher levels of physical activity than does the country as a whole, so it’s hard to tell whether cannabis motivated people to exercise more than is typical in those states.

Soon, researchers could have access to populations with a wider range of activity levels. “The good news for researchers is that states are legalizing crazy,” Bryan says. Eleven US states and the District of Columbia have approved recreational marijuana use, and 33 states allow medical marijuana.

Evidence versus anecdote

Although survey data are valuable for designing experiments, they will not provide the evidence that researchers such as Bryan crave. Currently, anecdotes concerning cannabis and exercise far outnumber controlled studies of the relationship, but that’s not to say that no one has tried.

In 2018, researchers at McMaster University in Hamilton, Canada, scoured the literature for studies of marijuana’s effect on athletic performance that included a control group. Only three small studies made the cut7.

Conducted between 1975 and 1986 in people under the age of 35, two of the studies in the review7 had participants exercise before and after smoking cannabis. The third study was purely observational.

In areas such as workout times, heart rate and blood pressure, the studies mostly recorded either no difference from the control groups, or negative effects.

The sole positive finding, from a study with 24 participants, was an increase in forced exhalation, or the amount of air participants could exhale after taking a deep breath.

On the basis of the studies’ low sample size and quality — two studies used marijuana containing about 1–2% THC, much lower than recreational levels in the United States, which in 2014 averaged around 12% — the authors concluded that the “effects of marijuana on athletic performance remain unclear”.

Despite the lack of evidence that cannabis enhances performance, the concern led the World Anti-Doping Agency (WADA) to ban cannabis use during competitions when it assumed responsibility for the list of prohibited substances in 2004.

According to WADA, which is based in Montreal, Canada, and is affiliated with the International Olympic Committee (IOC), the drug meets all the criteria for being banned.

As well as having potential to enhance performance, it poses health risks to athletes, and is illegal in many parts of the world.

Olivier Rabin, WADA’s senior science director, explained the agency’s reasoning for the cannabis ban in a 2011 paper8 co-authored by a researcher from the US National Institute on Drug Abuse. Although he acknowledges that the scientific evidence is shaky, Rabin says that the “wealth of testimonies” from athletes who admit to using cannabis to enhance their performance can’t be ignored.

These accounts — mainly unpublished reports made to WADA’s doping support hotlines — have come from a number of sports, he says.

For example, goalkeepers in football say that cannabis increases their focus, helping them drown out the many distractions in the stadium.

Athletes in other sports, such as skateboarding and skiing, say that cannabis reduces competition anxiety that can hinder performance.

Rabin says that athletes seem to be able to “titrate” their cannabis use to get just the results they want; he ns it to drinking just enough alcohol to be sociable at a party. Cannabis might not enhance performance at all doses and in all situations, he says, but its use could be advantageous in some circumstances.

More from Nature Outlooks

Over the past several years, as perceptions of marijuana have evolved in society, so too has WADA’s stance on the drug. In 1998, before WADA officially took on its anti-doping duties, Canadian snowboarder Ross Rebagliati was stripped of his Olympic gold medal after officials detected 17.8 nanograms per millilitre of THC in his system.

Rebagliati’s medal was reinstated soon after, on the basis that the IOC had not listed cannabis as a banned substance. In 2013, WADA raised the level of cannabis allowed in urine samples from 15 nanograms per millilitre to 150 nanograms per millilitre.

Rabin says that this higher level will focus WADA’s anti-doping efforts on active users of cannabis instead of infrequent users who aren’t trying to enhance their performance.

Even as public acceptance of marijuana grows, researchers are finding it difficult to fully investigate cannabis’s impact on physical activity because of the restrictions on cannabis research. Federal policy requires that scientists submit to an application process that can take six months to one year.

On approval, researchers are only allowed to use government-provided cannabis with levels of THC that are often lower than those of cannabis available to the public. “Until regulations change,” Ogle says, “we’re really thwarted from being able to do really good research that we know the public wants and needs.

Researchers are coming up with creative ways to get around these rules.

Some of Bryan’s collaborators in Colorado have created a mobile lab — essentially, a renovated van that can be parked outside participants’ homes — to test users after they have consumed their own product.

Because testing takes place off-campus, scientists aren’t subject to campus restrictions on cannabis. With these kinds of creative approach, Bryan says, scientists could start investigating the effects of cannabis on specific aspects of exercise such as inflammation.

But the question she’d most to answer is probably the most difficult one: does cannabis directly influence people’s decision to exercise? “To me,” says Bryan, “that’s the most interesting question out there.”

Know the Risks of Marijuana

Does Marijuana Affect School, Sports, or Other Activities?

Marijuana use comes with real risks that can impact a person’s health and life.

  • Marijuana is the most commonly used illegal substance in the U.S. and its use is growing. Marijuana use among all adult age groups, both sexes, and pregnant women is going up. At the same time, the perception of how harmful marijuana use can be is declining. Increasingly, young people today do not consider marijuana use a risky behavior.But there are real risks for people who use marijuana, especially youth and young adults, and women who are pregnant or nursing. Today’s marijuana is stronger than ever before. People can and do become addicted to marijuana.Approximately 1 in 10 people who use marijuana will become addicted. When they start before age 18, the rate of addiction rises to 1 in 6.

    Marijuana Risks

    Marijuana use can have negative and long-term effects:Brain health: Marijuana can cause permanent IQ loss of as much as 8 points when people start using it at a young age. These IQ points do not come back, even after quitting marijuana.Mental health: Studies link marijuana use to depression, anxiety, suicide planning, and psychotic episodes. It is not known, however, if marijuana use is the cause of these conditions.Athletic Performance: Research shows that marijuana affects timing, movement, and coordination, which can harm athletic performance.Driving: People who drive under the influence of marijuana can experience dangerous effects: slower reactions, lane weaving, decreased coordination, and difficulty reacting to signals and sounds on the road.Baby’s health and development: Marijuana use during pregnancy may cause fetal growth restriction, premature birth, stillbirth, and problems with brain development, resulting in hyperactivity and poor cognitive function. Tetrahydrocannabinol (THC) and other chemicals from marijuana can also be passed from a mother to her baby through breast milk, further impacting a child’s healthy development.Daily life: Using marijuana can affect performance and how well people do in life. Research shows that people who use marijuana are more ly to have relationship problems, worse educational outcomes, lower career achievement, and reduced life satisfaction.

  • Marijuana use during pregnancy can be harmful to a baby’s health and cause many serious problems.
  • How much do you really want to know about the risks of marijuana? You might be surprised.
  • Marijuana Addiction

    Contrary to popular belief, marijuana is addictive. Research shows that:

    • 1-in-6 people who start using the drug before the age of 18 can become addicted.
    • 1-in-10 adults who use the drug can become addicted.

    Over the past few decades, the amount of THC in marijuana has steadily climbed; today's marijuana has three times the concentration of THC compared to 25 years ago.

    The higher the THC amount, the stronger the effects on the brain—ly contributing to increased rates of marijuana-related emergency room visits.

    While there is no research yet on how higher potency affects the long-term risks of marijuana use, more THC is ly to lead to higher rates of dependency and addiction.

    About Marijuana

    Marijuana refers to the dried leaves, flowers, stems, and seeds from the Cannabis sativa or Cannabis indica plant. Marijuana is a psychoactive drug that contains close to 500 chemicals, including THC, a mind-altering compound that causes harmful health effects.

    People smoke marijuana in hand-rolled cigarettes, in pipes or water pipes, in blunts, and by using vaporizers that pull THC from the marijuana. Marijuana can also be mixed in food (edibles), such as brownies, cookies, and candy, or brewed as a tea. People also smoke or eat different forms of marijuana extracts, which deliver a large amount of THC and can be potentially more dangerous.

    Rise of Marijuana Use

    Today, marijuana use is on the rise among all adult age groups, both sexes, and pregnant women. People ages 18-25 have the highest rate of use.

    Marijuana and THC remain illegal at the federal level, even though many states have legalized its use. In states where legal, marijuana is a fast-growing industry with sales to individuals over 21 in retail stores, wineries, breweries, coffee shops, dispensaries, online, as well as grown at home.

Does Marijuana Affect School, Sports, or Other Activities?

  • What's the problem with youth using marijuana?
    • Marijuana is not always addictive to teenagers, but it can be. About 1 in 6 youth who use marijuana will become addicted, a number that increases the more the youth uses and the earlier they start.
    • Youth who use marijuana regularly are more ly to have difficulty learning, memory issues and have lower math and reading scores. The more marijuana youth use, the harder it may be for them to learn. These effects can last weeks after quitting. Using marijuana before the age of 25 can also affect brain development and especially in high doses, can cause temporary psychosis (not knowing what is real, hallucinations and paranoia) while the user is high.
    • In addition to its effects on the brain, marijuana smoke has other health effects. People who smoke marijuana daily or near-daily may have a persistent cough, bronchitis, mucus and wheezing. Marijuana smoke contains the same cancer-causing chemicals as tobacco smoke. Heavy marijuana smoking is strongly associated with tissue damage in the airways of your lungs.
    • Marijuana can also affect athletic performance and coordination. THC can interfere with reaction time and how someone experiences time and space. Using marijuana in any form will ly impair a teen’s ability to drive, play sports or do other activities they enjoy.

In Jefferson County, youth report that most marijuana is purchased from someone old enough to buy or grow it; though many youths also say they take it without permission from an adult who lives with them (2018 Youth Town Hall).

What worries you about  marijuana messing with kids' brain development?

Use of marijuana during the teen years results in damage to the teen’s rapidly developing brain, and can result in impaired cognitive function. Plus, the younger a person starts using marijuana, the more ly they are to use harmful substances later in life. 

  • By the time they are juniors and seniors in high school, 25% of Jefferson County students report using marijuana in the past 30 days. Youth report that marijuana use is common across many social groups, including gifted students, athletes, and those with involved parents.

Jefferson County High School Age Youth

Healthy Kids Colorado Survey, 2019

Conversation starters

  • When you see an ad for marijuana or go past a marijuana store, use it as an opportunity to ask questions.


  • Ask them what they think about the new Healthy Kids Colorado survey data from 2019. 
  • Talk with them about how marijuana is bought and sold, and about their thoughts on the ethics of youth helping distribute illegal substances. It's also a good idea to let your youth know your values around dealers, or «plugs,» selling harmful substances to other teens.
  • Ask if they ever see people using marijuana at school or in the community— and ask if they see it used as edibles, dabs, vape or other form.

Ask yourself

  • Are you being realistic? Assume your student has been exposed to marijuana and approach conversations with that assumption.
  • Are you assuming use is typical when it isn't? It's a mistake to accept marijuana use as inevitable— fewer than half of  Jeffco students report having ever tried marijuana by the fall of their senior year and only about 1 in 5 high school students report recent use.*
  • Do you know the right words? Words related to marijuana change all the time. Here are a few to know:
    • Plug: A person who sells alcohol, drugs or other things to people they know, often through social media
    • Dab: Taking a dab means inhaling the vapors from a concentrated form of marijuana made by an extraction method that uses butane gas. Dabs, also known as butane hash oil (BHO) — and sometimes called «budder,» «honeycomb» or «earwax» — are more potent than conventional forms of marijuana because they have much higher concentrations of the psychoactive chemical tetrahydrocannabinol, or THC, than is found in regular marijuana. 
    • K2, Spice, Fake Weed: A mixture of plant material sprayed with a synthetic compound that is similar to THC. ​​


Rules & Boundaries

  • Know where your teen is and who they are with when they are not at home.



  • If adults in your home use marijuana, make an agreement that they will never provide marijuana to those under 21. Also track the amount kept in the home and let your teens know you keep track of it. Even if your teen would never take these items without permission, locking them prevents your teen's friends, younger children, visitors to your home and pets from accessing them.


  • Keep alcohol, marijuana, prescription drugs and firearms in a locked cabinet or in locked room in your home.

Equity & Inclusion

  • Youth may be using alcohol, marijuana or other drugs to cope with boredom, conflict, trauma, depression, anxiety or stress.  These problems can be exacerbated by lack of access to care or exposure to systemic inequalities. If your teen needs help, please consider reaching out to their Jeffco high school nurse for resources.


  •  Youth who are members of groups who currently face discrimination tend to be arrested more often, and face more severe penalties, for use and possession of marijuana.​​ Black and Hispanic Colorado adults and youth continue to face disparately high marijuana related legal charges and school suspension. *
  • Youth in Colorado are suspended or expelled from school or involved with law enforcement for underage marijuana use, and youth of color or youth that experience a disability are more ly to be disciplined than white youth in Colorado.
    •  Ask your school about their discipline practices and code of conduct. Ask how they are implementing health and substance use education. Ask about Jeffco’s restorative practices and how they are being implemented equitably for all students.

Taking Action in your Community

Reduction of risk factors, and improvements in protective factors, can happen on multiple levels— within an individual, among friends and family, by adjusting systems in places schools or businesses, and on the policy level for towns, counties or states.  When improvements happen on all levels, our teens are most ly to thrive. Here are some policy and systems you and/or your teens might be able to influence:

  • Many Jeffco youth learn from other youth how to use marijuana, particular dabs and oils, at parties or gatherings in private homes. Cities can pass laws to fine homeowners or leaseholders when they  allow youth to consume substances on their property.
    • Join Jeffco CTC to address local policies and efforts that support youth.


  • Cites can restrict marijuana promotions, signage, merchandising, location, etc.. These types of policies may help reduce youth marijuana use. 
    •  Join Jeffco CTC to address local policies and efforts that support youth.  
  • The amount and content of health education students receive (including information about substance misuse and effective skill development) varies by school. 


  • Having data in our county on youth marijuana use and behaviors helps to bring in resources and support for youth.
    • Email the local Board of Education (see example letter here) to share your support for the Healthy Kids Colorado Survey to get important information on youth needs in our community. 
    • Join your School Accountability Committee and ask about using non-academic data and information (e.g., health information, climate survey data, etc) to guide school improvement efforts and plans.


Does Marijuana Affect School, Sports, or Other Activities?

Does Marijuana Affect School, Sports, or Other Activities?

Call it weed, pot, grass, dope or marijuana, they all are just different names for the drug extracted from cannabis plants. It can be smoked, drunk, vaped or eaten in the form of edibles – depending on personal preference.

Used for pleasure and recreation, marijuana has compounds that alter the user’s mind and affect both the brain and body. Apart from its medicinal benefits, marijuana is also addictive and harmful to some. Its usage has negative elements attached to it, especially if the user is very young and school-going.

This is because learning, sports and judgment are the three key areas among teens and children that are impacted by smoking marijuana.

Marijuana and School Students

Kids disengaged from their educational institutions believe that smoking a joint before doing their homework is a good idea, but research shows otherwise.

Studies have proven that consuming weed dulls cognition and makes learning a difficult task. Marijuana directly affects the attention span and memory negatively, especially in teens and young adults.

It takes them longer to do tasks that are complex due to a lack of focus and concentration.

Recent research by the University of Waterloo states that students of high school level and those pursuing university tend to get poor grades when they smoke marijuana regularly.

It is a fact that the human brain keeps developing actively until an individual reaches the early twenties.

Studies suggest that adults who smoke the drug unceasingly during their juvenile years display lower neural connectivity in all regions of the brain responsible for inhibitions, learning, and memory.

It has been seen in students who consume marijuana a minimum once per month that they start skipping classes, leave their homework unattended and incomplete, are careless for good grades, and lose motivation to apply themselves to their studies.

Over time, even if they try to focus, they are less ly to get high grades.

Compared to non-users who showed their willingness to pursue university, the students who use drugs at least once a day reported considering dropping out or stopping their education at the high school level itself, sometimes before.

Discouraging Marijuana Use

The negative effects of consuming marijuana once can linger on for days and even weeks. These effects ensure that the student operates at low mental capacity both in school and at home.

Marijuana users themselves report poor outcomes in studies and below-par achievement despite investing the same amount of time and energy that they were investing before.

It seems as though a single high can leave lasting effects on a student’s performance.

Several surveys, research studies, and reports have suggested prevention tactics that point to a change in the environment. It turns out prevention and delay in the introduction of marijuana use among young adults is the key to combating widespread marijuana use.

To create more awareness and educate the public at large, it is necessary to scale up health prevention. Only awareness can truly fight the high rates of marijuana consumption among youth, which is higher than cigarettes.

More the frequency of the usage of marijuana, the higher the chances and greater the risk of less engagement and bad school performance by all students who pursue the drug.

These facts and findings of marijuana affecting school students are well researched and well documented in the Journal of School Health of the University of Waterloo.

Marijuana and Its Effects on Sports

Marijuana has never been as accessible or popular as it is now. The legalization process began with the fight for access to medical marijuana that helped with the pain, but the access might have gone a little too unchecked. Debates have sprung up in the sports industry as well.

In contrast, marijuana indeed undergoes considerable regulatory review in various jurisdictions globally, both for medical and non-medical approaches.

But is it really true that marijuana is a miracle drug? Can it have a significant impact on an athlete’s health and performance in competition? Or do its negative effects exceed its benefits?

The legalization of marijuana in different parts of the US happened due to its promised function of helping manage chronic pain in cancer patients and those with other chronic illnesses. But over time, a lot of myths about the drug also began floating.

Researchers have started quashing several of the myths associated with marijuana. Experts in the fields of cannabis, medicine and fitness have listed nine different ways that marijuana could benefit or risk athletic performance.

The effect of its consumption largely depends on the method, quantity, and frequency of consumption.

Benefits of marijuana for athletic performance:

  •    Reduction of Inflammation– One of the most promising benefits of marijuana is to reduce inflammation of joints and muscles. CBD, the non-psychoactive cannabinoid in marijuana, has the anti-inflammatory property that helps to ease inflammation. Fitness experts and yoga instructors regularly use marijuana and recommend its usage to their clients.

    They find marijuana to be quite a helpful tool to deal with pain and inflammation.

  •    Ease of Soreness– Combined with its anti-inflammatory property, cannabis is found to lessen pain considerably. It can help relieve muscle soreness from strenuous workouts. It has been proved by various researches that marijuana reduces acute to chronic pains and even muscle spasms.

    Fitness trainers advocate for therapies marijuana for recovery for muscle and relief from pain from injuries. They find the pain mediating, stress-reducing, anti-inflammatory and antioxidative properties of cannabis better than painkillers and opiate treatment.

  •    Treatment of Muscle Spasms– Athletic muscle spasms and the ones corresponding with diseases such as multiple sclerosis and Parkinson’s are well treated by using cannabis. Though there is less scientific evidence to prove its effectiveness on humans, the benefit is assumed because of the anti-inflammatory properties of the compound.
  •    Improved Sleep – Sound sleep is critical for good fitness and highly beneficial for athletic performance. Studies have proven that inducing sleep by consuming THC not only helps with sleep apnea but suppresses dreams and consumption of CBD eases sleep disorders and fatigue. It also induces relaxation in the body for a restful sleep.

    Marijuana is a good alternative for conventional sleep medications and helps improve sleep, its duration and decreases stress.

  •    Better Mental Capacity – Though not proven scientifically for humans, marijuana still finds acceptance among some fitness experts. They claim it helps them to ‘get in’ their zone for workouts.

    Regular and low consumption of THC reduces anxiety before a major game or match and helps athletes stay calm and focus on training – something that they find it crucial for success in athletics.

Risks of consuming marijuana for athletic performance: 

  •    Damaged lungs – As healthy lungs are vital for strong fitness and the overall performance of an athlete, smoking marijuana can lead to lung damage. When lungs function at reduced capacity, it can structurally hurt an athlete’s performance significantly.
  •    Impaired Motor Skills – Marijuana, any other intoxicant, notably impairs motor skills. Its use acutely impairs the process of decision making and motor coordination that affects activities such as driving. Athletics involve a lot of quick, split-second decisions during a game that might cost an athlete their health. Even advocates of marijuana’s healing properties do not support the use of marijuana during physical activities.
  •    Increased lihood of Chronic Depression – Humans wish to ensure that the benefits of using a therapeutic compound outweigh the risks. And one of the risks associated with continued and heavy use of marijuana is an increased prospect of depression. Depression decreases motivation and creates a number of side effects, thus being detrimental to fitness, routine, and motivation.
  •    Risk of Increased Heart Attack – Strenuous exercising schedule under the influence of marijuana can also increase chances of heart attack for all who have a history of heart problems. It is believed that the attack can happen within an hour of consuming marijuana and rushing through the workout.

Long Term Effects of Marijuana

Negative effects of marijuana on aspects such as learning, memory and attention often last for a long period. Depending on the user’s history of consuming drugs, the effects could last for more than a week after the severe effects have worn off. Hence daily marijuana smokers might function at a lower intellectual level for most of the time.

Research and evidence suggest that nonsmoking students perform better and have higher educational outcomes than their smoking peers.

While the role of other factors cannot be ruled out in the negative outcomes of life, marijuana’s use is closely linked to unemployment, criminal behavior, low income, heavy dependence on welfare and below-par life satisfaction. Only further research can ascertain the role marijuana use plays in these associations.


When their judgment is impaired, teens can go from losing their future prospects to losing their lives by driving a vehicle under the influence of marijuana. Despite its numerous health benefits, marijuana is also a risk to health and well-being.

It is rated worse than alcohol and tobacco when it comes to judgement impairment.

With the legalization of marijuana around the globe, understanding and promoting the risks in addition to its benefits will be critical for the successful transition of youth into adulthood.
