Risks Of Marijuana Addiction

Does Marijuana Cause Permanent Brain Damage in Adults?

Many brush off the findings of studies such as these that identify marijuana as a substance of abuse that can cause addiction, mental health problems, social and relationship issues, and in some cases, contribute to early death. But the fact is that marijuana is addictive and an estimated 9 percent of users develop an addiction to the drug, a percentage that increases significantly if the onset of use is during the teen years and if the person uses the drug daily. Marijuana addiction can cause all the problems associated with addiction to any drug of abuse, including:

Physical illness: Depending upon the method of ingestion, the physical health effects of marijuana will differ for the chronic user. Smokers may struggle with respiratory problems, including chronic cough, asthma, and other issues. Those who eat the edible version of the drug may struggle with gastrointestinal issues. Additionally, accidents and medical emergency caused by marijuana use have caused a significant increase in emergency room admissions.

Difficulty maintaining employment: Under the influence of marijuana, its difficult to focus, to get places on time, to think clearly, and to manage big picture tasks as well as the little details. In short, those who smoke marijuana frequently, even if they dont smoke it while on the job, may be less motivated employees and thus may have a difficult time getting or keeping jobs.

Previous Hypotheses About The Association Of Cannabis And Schizophrenia

There currently is considerable debate about the reasons for the association of cannabis with schizophrenia in both clinical and population based samples. Among the hypotheses proposed are that common independent factors explain the co-occurrence cannabis causes psychosis that would not have occurred in the absence of cannabis use cannabis precipitates psychosis only among persons who were genetically vulnerable to developing the disorder cannabis initiates an early onset of an already predetermined psychosis and its use worsens or prolongs the psychosis and that persons with psychosis proneness are more likely to become regular or problematic cannabis users than persons without such traitsi.e. the self-medication hypothesis. Although some investigations seem to at least partially support the last explanation , there has been little evidence for it and, although implied, no current explanation has yet suggested that cannabis directly damages the brain in regions that are crucial for developing psychiatric symptoms, such as frontal and temporal cortex. Furthermore, one can hypothesize that should there be an interaction between the genetic vulnerability for schizophrenia and the heavy use of cannabis, this may be a direct consequence of both on brain structural organization in an additive or interactive fashion. Whether either is the sole factor is currently unknown.

Effects Of Eating Edibles

Edibles are food items that have been infused with weed. Edibles can come in gummies, cookies, brownies, or even savory dishes. You can buy delta 8 gummies and other edibles online. The effects of edibles can be very intense and long-lasting because they’re absorbed through your digestive system. These edibles usually take two hours to kick in, but the effects can last up to 12 hours.

Edibles can be a great way to consume weed if you don’t want to smoke or vape. However, they can be very dangerous if not used properly. Because edibles take a while to kick in, it’s easy to overeat before you start feeling the effects. Overeating weed can lead to anxiety, paranoia, and even hallucinations. It’s essential to begin with, a low dose of edibles and wait at least an hour before consuming more.

Effect Of Marijuana Use On Iq

The effect Marijuana has on the brain is influenced by the amount a person has smoked and the users age. Individuals under 25, whose brains are still developing, are most susceptible to the effects of Marijuana on the brain. A study of Marijuanas effect on IQ revealed individuals who began using Marijuana at a young age lost 6 to 8 points from their IQ by middle age. Moreover, those who smoked Marijuana throughout their adolescence, then stopped, did not regain their IQ points. Conversely, individuals who began using Marijuana in their adulthood did not experience any IQ loss.

Other Ways Marijuana And The Brain Affect Each Other

While there are mixed research results when it comes to marijuana and the brain, there are other things to be aware of if you use marijuana.

There have been multiple studies showing that people who use marijuana regularly are at a higher risk of psychosis and in some studies, people who regularly used marijuana for years had a small volume of gray matter in certain areas of their brain, but at the same time, they had higher levels of connectivity.

So, to sum up, does marijuana kill brain cells?

Whats interesting is that when older people use marijuana, it seems to do somewhat the opposite and restore some of the functionality of an aging brain to look more like a younger brain.

Of course, the studies on marijuana and the brain are still somewhat limited, and you should never try to smoke marijuana as a way to gain any sort of brain advantage because there are risks.

The Brains Effects Of Synthetic Marijuana:

Although synthetic marijuana isnât safe for humans, it has gained popularity in recent years.

It is also known as âFake Weedâ and can have mind-altering effects that cause individuals to behave strangely. Synthetic Marijuana can be illegal.

It may contain toxic ingredients that can increase heart rate, bleeding, or cause vomiting.

Synthetic Marijuana acts in the same way as by attaching to the Cannabinoid Receptor Type 1 located in the central and peripheral nervous system.

Synthetic marijuana is stronger than THC in binding to CB1 receptors, which makes it 100 times more potent in the brain.

Side effects of CB1 receptors can be severe and even fatal because they are located in multiple places in the brain.

What is the difference between weed, alcohol, and nicotine?

Nicotine, alcohol, and marijuana have different effects on the neurological system, which can lead to different long-term effects on the brain.

The main difference between nicotine and alcohol is that they are neurotoxic. This means that they can kill brain cells.

It is not yet known if marijuana can cause brain damage.

All three substances have important similarities. One is that their cognitive effects are stronger in young people.

However, these effects vary depending on the substance.


Why Occasional Marijuana Use Can Cause Problems

“People think a little recreational use shouldn’t cause a problem if someone is doing OK with work or school. Our data directly says this is not the case,” Breiter said in a news release.

Other researchers, not involved in the Massachusetts General study, agreed that finding changes in the brains of casual marijuana users was surprising.

“This study suggests that even light to moderate recreational marijuana use can cause changes in brain anatomy,” said Carl Lupica, Ph.D., of the National Institute on Drug Abuse. “These observations are particularly interesting because previous studies have focused primarily on the brains of heavy marijuana smokers, and have largely ignored the brains of casual users.”

The research was funded by the National Institute on Drug Abuse, the Office of National Drug Control Policy, Counterdrug Technology Assessment Center, and the National Institute of Neurological Disorders and Stroke.

The Harmful Effects Of Marijuana

The immediate effects of taking marijuana include rapid heart beat, disorientation, lack of physical coordination, often followed by depression or sleepiness. Some users suffer panic attacks or anxiety.22

But the problem does not end there. According to scientific studies, the active ingredient in cannabis, THC, remains in the body for weeks or even months.23

Marijuana smoke contains 50% to 70% more cancer-causing substances than tobacco smoke.24 One major research study reported that a single cannabis joint could cause as much damage to the lungs as up to five regular cigarettes smoked one after another.4 Long-time joint smokers often suffer from bronchitis, an inflammation of the respiratory tract.25

The drug can affect more than your physical health. Studies in Australia in 2008 linked years of heavy marijuana use to brain abnormalities.26 This is backed up by earlier research on the long-term effects of marijuana, which indicate changes in the brain similar to those caused by long-term abuse of other major drugs. And a number of studies have shown a connection between continued marijuana use and psychosis.27

Thus even small amounts of marijuana can cause temporary sterility in men.28 Marijuana use can also disrupt a womans menstrual cycle.29

Studies show that the mental functions of people who have smoked a lot of marijuana tend to be diminished. The THC in cannabis disrupts nerve cells in the brain, affecting memory.30

Does It Promote Hippocampal Neurogenesis

Marijuana: Heavy Users Risk Changes to Brain

One of the most widely reported positive effects of cannabis is the ability to promote the formation of new neurons in the hippocampus, a region of the brain involved in memory processing.

In fact, one of the medicinal applications of cannabis takes advantage of this factor and the fact that it reduces the formation of betaamyloid protein in order to help fight certain disorders that cause progressive degeneration of the hippocampus.

However, this has recently been seen to occur in laboratory rats used for experiments, but not in humans: in our case, the birth of new hippocampal neurons is practically non-existent in adults.

How Marijuana Works On The Brain

THC attaches to cannabinoid receptors in the brain and in peripheral tissues. When these receptors are activated, they can alter your mood, change cognition, and increase your appetite. The effects of marijuana are dose-dependent, which means you may experience symptoms at high doses that you wouldnt feel at lower doses and vice versa. For instance, larger doses of marijuana can impair your memory and cognitive functions while lower doses may only cause mild effects.

Marijuana is often taken to achieve a high, but some users claim that it promotes creativity. However, that may not be true. A study published in 2014 looked at the relationship between cannabis use and creative thinking. Participants performed a series of tasks that required divergent thinking and gave them a low dose of cannabis, a high dose, or a placebo.

People who used low doses didnt have any notable increase in creativity as compared to the placebo group. People who used a high dose actually experienced impaired creativity. If youre an artist, marijuana may not be the creativity enhancer you might want it to be.

Heavy Marijuana Use May Damage The Brain

    Heavy marijuana use over a long period of time may severely damage the brain, according to a new review of previous research.

    In the review, the researchers also described the case of a 52-year-old man who died after using marijuana. The man, who had previously had depression, died from injuries he sustained when he jumped in front of a car after smoking pot and losing touch with reality. An analysis of the man’s brain revealed severe damage that doctors attributed to the man’s heavy marijuana use over the two decades prior to his death.

    “When we looked at the brain, it had horrible degenerative changes,” said Dr. Suzanne M. de la Monte, a professor of neurosurgery at Brown University in Providence, Rhode Island, who co-authored the review and examined the man’s brain after his death.

    The researchers said they don’t know exactly how much marijuana the man used in the years before his death. But blood tests conducted on several occasions before the man was admitted to the hospital the last time showed high levels of , de la Monte told Live Science. Moreover, both the patient and his family told doctors about the man’s heavy marijuana use, de la Monte said. People who use marijuana at lower levels may not suffer such drastic consequences.

    This case and other research cited in the review suggest that chronic, heavy marijuana use may cause cognitive impairment and brain damage, the researchers wrote in their review, published in the journal Pediatric Neurology.

    Symptoms Of Marijuana Withdrawal

    The following are some of the most common cannabis withdrawal symptoms:

    • Dry mouth, excessive thirst, or dehydration
    • Stomach or digestive problems
    • Feelings or symptoms of depression
    • Difficulty focusing
    • Cravings for marijuana

    Most of the symptoms of marijuana withdrawal arent immediately physically dangerous, but this does not mean that they shouldnt be taken seriously. If you dont address these symptoms, they could lead to serious health consequences. For example, many people lose their appetite and struggle to eat while theyre detoxing from marijuana. If your nutritional needs arent met, youll have an increased risk of other health problems. Dehydration is another common issue associated with marijuana use, and severe and long-term dehydration can affect your heart, muscles, and nervous system.

    What Does Marijuana Do To You

    Scientists warn smoking super skunk causes brain damage

    The National Institute on Drug Abuse explains how marijuana affects someone either by smoking it or ingesting it as an edible form of THC.

    When marijuana is smoked, THC and other chemicals in the plant pass from the lungs into the bloodstream, which rapidly carries them throughout the body to the brain. Many people experience euphoria, relaxation, heightened sensory perception , laughter, altered perception of time, and increased appetite. If marijuana is consumed in foods or beverages, these same effects are delayedusually appearing after 30 minutes to 1 hourbecause the drug must first pass through the digestive system.

    How much do you really want to know about the risks of marijuana? You might be surprised.

    • 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 brainlikely 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 likely to lead to higher rates of dependency and addiction.

    The Effect Of Marijuana On The Teenage Brain

    When a person uses marijuana, the principal psychoactive chemical called tetrahydrocannabinol passes from the lungs or digestive tract into the bloodstream. The blood carries THC to the brain, where it acts on specific cannabinoid receptors. These receptors are predominantly found in areas of the brain associated with concentration, thinking, sensory and time perception, pleasure, memory, and coordination.3 Over activation of these areas by THC causes the high that people feel.4 such as attention, memory, and learning, and these effects can last up to several days beyond the time of actual high.5

    Unfortunately for teenagers, marijuana use can have much more long-term effects. The teenage brain is not yet fully mature, with neurodevelopment continuing until at least the early or mid-20s. During adolescence the brain is particularly sensitive to drug exposure, and marijuana use impacts how connections are formed within the brain.3 Other effects on the developing brain include interference with neurotransmitters and abnormal brain shape and structure volume.6

    Studies have shown that the use of marijuana is associated with reduced cognitive function in teens.7 One study found that teens who regularly use marijuana lose an average of 5.8 IQ points by the time they reach adulthood.8 A recent study found that marijuana has a more negative impact on a teenagers cognitive development than alcohol.9

    All About Marijuana And Brain Health: The Good And The Bad

    Lets start by covering the basics. Most of us know by now that marijuana is a plant that occurs naturally. It is actually a plant known as cannabis. As is the case with most plants, cannabis can come in a couple of different types. The two main types of cannabis are Cannabis sativa and Cannabis sativa L.

    Cannabis sativa L is the non-psychotropic, or non-mind altering, type. It is most commonly used in the materials industry. It can be used to produce oils, materials for clothes, rope, and much more. Its commonly referred to as hemp. More now than ever before, it can also be found within a variety of beauty products like lotions and shampoos. Some crafting kits even boast the inclusion of hemp string for friendship bracelets.

    Part of this major uptick in the use of hemp is due to its small environmental impact compared to most synthetic materials. This actually is part of what draws people to using marijuana as well for things like anxiety or pain instead of pharmaceutical options.

    States Ok Marijuana Use

    What Does Cannabis Do To The Brain? | Earth Lab

    Grant’s analysis, published in the July issue of the Journal of the International Neuropsychological Society, comes as many states consider laws allowing marijuana to be used to treat certain medical conditions. Earlier this year, Maryland became the 10th state to allow marijuana use to relieve pain and other symptoms of AIDS, multiple sclerosis, cancer, glaucoma, and other conditions — joining Alaska, Arizona, California, Colorado, Hawaii, Maine, Nevada, Oregon, and Washington.

    Medicinal marijuana is available by prescription in the Netherlands and a new marijuana drug is expected to be released in Great Britain later this year. In the U.S. and elsewhere, , a drug that is a synthetic form of marijuana and contains its active ingredient, THC, is available by prescription to treat loss of appetite associated with weight loss in AIDS patients.

    Grant says he did the analysis to help determine long-term toxicity from long-term and frequent marijuana use. His center is currently conducting 11 studies to determine its safety and efficacy in treating several diseases.

    “This finding enables us to see a marginal level of safety, if those studies prove that cannabis can be effective,” Grant tells WebMD. “If we barely find this effect in long-term heavy users, then we are unlikely to see deleterious side effects in individuals who receive cannabis for a short time in a medical setting, which would be safer than what is practiced by street users.”
