What Happens When You Smoke Marijuana

Is marijuana bad for your brain? – Anees Bahji

When you use marijuana, the psychoactive ingredient of the brain called THC can stimulate the exact parts of the brain which firmly answer to the fun of food and sex. Furthermore, it can even release a chemical called dopamine. It can delight you and give you a very comfortable sensation.

Moreover, if you smoke or vape marijuana, the THC attaches to your bloodstream. Hence you get to your high point within a few minutes. THC can keep the effects of marijuana for at least two to three hours. Also, it can peak within thirty minutes.

It is very crucial since the pot effects depend on the ratio of THC with other compounds in the body. If you smoke pot, the THC ratio will increase compared to other compounds. However, if you eat or drink marijuana, pot effects will take many hours to wither off and bring you back to fully sober.

Marijuana affects your brain directly, and the potential to recreate things can be out of your league. It is even the same for medical marijuana.

What Does Thc Do To The Body

THC can affect your body in many different ways, subject to your method of consumption. Inhaling cannabis impacts your body much faster than ingesting it in edibles.

The way you ingest marijuana can also affect your body. Smoking or vaping can irritate your lungs, mouth, and throat. It can also exacerbate a respiratory condition if you have one.

What does THC do to your body? The answer differs from person to person. THC brings much-needed pain relief to some, while it may increase anxiety levels in others.

THC may increase the users heart rate, posing a risk to someone with a cardiac condition. For these people, the chances of a heart attack may increase when consuming marijuana.

Your body can enjoy immediate benefits from THC, but there are also long-term effects that may develop if used too often and for too long.

How Do People Use Marijuana

People can smoke marijuana rolled up like cigarettes, put it into tea, or cook it into food or candy. Some people think that it is safer to inhale marijuana using electronic cigarettes, or vaping devices, because they are not inhaling smoke. This is called vaping. But studies show that vaping can be harmful because you still inhale the same brain-altering chemicals.

How Long Does Thc Stay In Your Body And For How Long Can It Be Detected After You Use Marijuana

The amount of time depends on several factors such as how much a person has smoked, how long a person has smoked for, and the method used to detect THC or its metabolites. Marijuana can be detected in urine, blood and saliva using methods called thin layer chromatography, high pressure liquid chromatography, gas chromatography, enzyme immunoassay and radioimmunoassay. The most psychoactive ingredient in marijuana is delta-9-tetrahydrocannabinol . THC is broken down into several other compounds that are also psychoactive. The half-life of THC is about 24 hours. However, the metabolites of THC can be detected for 45 to 60 days after the last use.

According to Maistro et al., in the book Drug Use and Misuse :

“Approximately half of the THC is excreted over several days, and the remainder by the end of about a week. However, some metabolites of the THC, a number of which may still be active in the system, can be detected in the body at least thirty days following ingestion of a single dose and, following chronic use, in the urine for several weeks.”

Munchies And The Brain

What 5 Popular Drugs Including Weed And Booze Do To Your Body And Brain ...

Marijuana may affect certain neurons in the brain that are normally responsible for suppressing appetite, and this effect may explain why people often get very hungry after smoking pot, according to a 2015 study in mice. In the study, researchers stimulated the mice’s appetites by manipulating the same cellular pathway as the one that mediates pot’s effects on the brain, and then observed what was going on in the mice’s brains during the experiment.

The scientists expected that the neurons that typically suppress appetite would be turned off by their efforts to stimulate the rodents’ appetites. But, contrary to their expectations, it turned out that those neurons were actually activated, because they had switched to releasing chemicals that promote hunger, study author Dr. Tamas Horvath, a professor of neurobiology at Yale University, told Live Science in a 2015 interview.

It’s not clear whether it would work the same way in people, the researchers noted. But it has been suggested that using marijuana makes people hungry, they said.

The finding could point to a way to treat the loss of both appetite and weight that some cancer patients experience while undergoing treatments, the researchers said.

How Does Marijuana Affect The Brain

As recreational Marijuana use becomes legalized throughout the US, many people now wonder how affects the brain and whether or not it kills brain cells. Just as years of heavy alcohol, Meth, and Heroin use can cause some irreversible brain damage, prolonged Marijuana abuse can affect the ability of brain cells to convey messages . Using Marijuana can cause damage to brain cells that results in a number of concurrent symptoms throughout the body.

Like other drugs, components of Marijuana bind with specific receptors in the brain. Tetrahydrocannabinol is Marijuanas primary Psychoactive ingredient, and it attaches to the brains Cannabinoid receptors . These receptors connect to nerves in the brain which govern memory, appetite, pain regulation, and mood.

When a person smokes Marijuana, they may notice they struggle with staying focused or recalling important details. This can worsen with prolonged Marijuana use, resulting in problems like poor memory and concentration. Motor skills can also be affected by the drug. If users decide to drive while high, they can endanger their lives and the lives of others.

Break free from addiction.

It May Affect Your Mental Health

Not everyones experience with marijuana is pleasant. It often can leave you anxious, afraid, or panicked. Using pot may raise your chances for clinical depression or worsen the symptoms of any mental disorders you already have. Scientists arent yet sure exactly why. In high doses, it can make you paranoid or lose touch with reality so you hear or see things that arent there.

The First Couple Of Hours After Taking Marijuana

Since THC can act as a natural receptor within the endocannabinoid system, expect neurons that fire up. So your thoughts and perception are magnified as you reach a different level of a tangent. Marijuana is also like caffeine, sugar, and alcohol. They all affect the dopamine levels present in the brain. Thats why you get to feel more relaxed and euphoric all at the same time.

So thats why you have to avoid driving, studying for an exam, and doing sports that need coordination like baseball or tennis when youre high. Marijuana impairs your ability to create new memories. It would even make you crave munchies.

However, effects may vary as it will depend on the amount of weed taken. Another thing that would matter is the potency of the strain. Mild ones can have 2 to 5% THC. While the strong varieties range from 20% to 25%. It can even skyrocket to 30%. High doses can make you just curled up on the couch for hours with some hallucinations going on.

Each person may have a different experience. It depends on the strains potency and your condition. Some may find it relaxing and enjoyable. Unfortunately, some may find it the other way around. Symptoms may worsen for people who suffer from anxiety or individuals who are prone to a panic attack. Better spare yourself from this happening.

What Does A Persons Brain Look Like When Deciding To Smoke Weed

What Does Cannabis Do To The Brain? | Earth Lab

Decision-making is a complex process thatâs not limited to just one part of the brain. A 2015 fMRI study published in the journal Neuropsychopharmocology centered on 17 participants as they made the decision to smoke. The results suggested that the choice to smoke marijuana is accompanied by a consistent level of activation in a range of brain regions.

Brain imaging showed activation in the subjectsâ dorsal striatum, insula, posterior parietal regions, anterior and posterior cingulate, and dorsolateral prefrontal cortex as the person decided to smoke marijuana.

This fMRI fingerprint of the decision to smoke marijuana allowed researchers to distinguish smokers from non-smokers with 100 percent accuracy, suggesting that a personâs brain activates in a distinct pattern when making the decision to smoke marijuana.

The functions of these brain regions tell us a little little bit about the decision to smoke weed, too:

  • The dorsal striatum is associated with calculating rewards and making decisions.
  • The insula is associated with initiating actions based on a personâs physical state.
  • The posterior cingulate cortex, while not fully understood, is thought to either direct oneâs focus of attention or be associated with internally-directed cognition.

Cannabinoid Mechanisms In The Hippocampus And Effects On Memory

One of the well established effects of acute intoxication with cannabis in man is an impairment of shortterm memory . Many studies have shown significant effects on shortterm memory, particularly when tests were used that depend heavily on attention . Animal studies have also found that THC, synthetic cannabinoids and anandamide cause deficits in shortterm memory in spatial learning tasks . These include delayed matching or nonmatching tests in rodents , performance in a radial arm maze , and a fixed ratio food acquisition task in squirrel monkeys . The effects of both cannabinoids and anandamide were reversed by rimonabant, indicating that they are mediated by the CB1 receptor.

One approach to answering the question of what role the tonic release of endocannabinoids may play in hippocampal function has been to examine the effects of CB1 receptor knockout or of selective CB1 receptor antagonists. Un fortunately, these studies have so far yielded conflicting results. reported a significant enhancement of LTP in CB1 knockout mice, and found a significant enhancement of memory in such animals. However, tests with the CB1 antagonist rimonabant showed no effects on LTP or on learning and memory in a spatial learning task , although

How Is Marijuana Used

People can smoke marijuana in many different ways. However, the most common way to smoke marijuana is by rolling cigarettes up with marijuana or in an OCB roll. Some people even prefer to eat or drink weed. They mix it with their tea or even cook their food with marijuana.

There are many devices to light up marijuana. People use electric cigarettes or some smoking device called vaping. Furthermore, some people prefer to smoke it instead since they feel it is safe to inhale.

However, some studies also showed that vaping is as dangerous as inhaling weed since some chemicals exist.

How Does Pot Intoxicate Us

The “high” of THC comes from a chemical called dopamine. Dopamine is released by the brain to reward us for behaviour that, historically, has improved our chance of survival.

For example, through most of human history, food has been scarce. Our brains would reward us with a dopamine rush when we ate high-calorie food.

This reward system uses anandamide to release dopamine in small amounts.

Ingesting THC causes the brain to release much more, and THC lasts longer than anandamide.

It tricks our ancient survival system into creating a feeling of well-being.


Cannabinoids And The Neocortex

What 5 Popular Drugs Including Weed And Booze Do To Your Body And Brain ...

Like other intoxicant drugs cannabis causes profound changes in a variety of higher brain functions. The literature on the acute effects of the drug in human subjects is large, and can only be summarized here . The distribution of CB1 receptors in the neocortex has been described in detail . As in the hippocampus, the majority of cortical interneurons expressing high levels of CB1 receptor are GABAergic cells, which also express cholecystokinin . CB1positive terminals are concentrated in layers IIIII and layers VVI, with few in layers I or IV. Despite the obvious importance of the abundant CB1 receptors in the neocortex there have so far been few electrophysiological studies of their effects on neural activity.

have suggested that anandamide may play a role in the control of the sleepwaking cycle.

Some Athletes Think Marijuana Could Be Used In Ways That Might Improve Certain Types Of Physical Performance

Some athletes, especially in certain endurance and adventure sports, say marijuana use can boost their athletic performance. This may be because of anti-inflammatory or pain-relieving effects that make it easier to push through a long workout or recover from one.

At the same time, there are ways that marijuana could impair athletic performance, since it affects coordination and motivation, and dulls the body’s natural recovery process.

Without more research, it’s hard to know how marijuana affects athletic performance.

There’s Evidence That Marijuana Use During Pregnancy Could Have Negative Effects

According to the new NASEM report, there’s substantial evidence showing a link between prenatal cannabis exposure when a pregnant woman uses marijuana and lower birth weight. There was limited evidence suggesting that using marijuana during pregnancy could cause complications and increase the risk that a baby would have to spend time in a neonatal intensive care unit.

A study published in JAMA Psychiatry in September 2020 found that pregnant women who used marijuana had a higher risk of their children having ADHD and/or psychotic behaviors that have been linked to schizophrenia.

And an analysis, published in Nature Medicine in August 2020, linked cannabis use among pregnant women to autism in their children. The study, conducted in Ontario, Canada, involved data from 3,000 women who used cannabis during pregnancy.

Weed Can Impair Your Brain

Weed can make it harder for you to learn, focus, and remember things. This is a short-term effect and mostly wears off within 24 hours after you stop using weed.

However, using weed heavily, especially in your teens, may leave more permanent effects. Imaging tests conducted on a few adolescents found that weed may physically change the brains of certain individuals. Most affected teens had fewer connections in their brains in areas linked to alertness, memory, and learning. Tests also show lower IQ scores in some people.

Some Women Have Reported Having More Satisfying Sex When Using Marijuana

Your Brain on Drugs: Marijuana

A small study of 373 women from of varying races, sexual orientations, and marital statuses found that people who said they used marijuana before sex tended to have a more pleasurable experience than those who did not use the substance.

Specifically, some women reported having more satisfying orgasms and an increase in their sex drive.

Researchers weren’t able to pinpoint why marijuana had this effect, but suggested it could be due to the substance’s ability to reduce stress and anxiety.

Your Thinking Might Get Distorted

Weed can cloud your sense of judgment. But the effects differ in terms of how much you consume, how potent the strain is, and how much weed youve used in the past. In some cases, weed:

  • Heightens your senses. Sounds might seem louder and colors brighter.
  • Hurts your motor skills, thus reducing your response time. This can make driving more dangerous.
  • Distorts your sense of time.
  • Lowers your inhibitions. This might cause you to take risks, such as engaging in risky sex.

What About Medical Marijuana

Research shows that some of the chemicals in marijuana might be helpful with some kinds of pain, nausea, or possibly other conditions. Some states allow people with a wide range of illnesses to get marijuana legally as medicine, even though science hasnt proved it works for many of these illnesses. The government has also approved a few medicines in pill form that have marijuana chemicals in them but dont make you high. Only a doctor can give you these medicines. Scientists are looking at ways that chemicals in marijuana can help with other conditions, but it will take years of research.

It May Harm Your Heart

Marijuana makes your heart work harder. Normally the heart beats about 50 to 70 times a minute. But that can jump to 70 to 120 beats or more per minute for 3 hours after the effects of pot kick in. The added strain plus tar and other chemicals in pot may raise your chance of heart attack or stroke. The danger is even bigger if youre older or if you already have heart problems.

Cannabis And Psychiatric Illness

What 5 Popular Drugs Including Weed And Booze Do To Your Body And Brain ...

A temporary form of druginduced psychosis can occur in some cannabis users. In some of the psychiatric literature this is referred to as cannabis psychosis . Research psychiatrists, particularly in Britain , have studied this condition carefully. It nearly always results from taking large doses of the drug, often in food or drink, and the condition may persist for some time, perhaps as the accumulated body load of THC is washed out. The acute toxic psychosis that is sometimes caused by cannabis can be sufficiently serious to lead to the subject being admitted to hospital, and the initial diagnosis can be confused with schizophrenia, since the patients may display some of the characteristic symptoms of schizophrenic illness. These include delusions of control , grandiose identity, persecution, thought insertion, auditory hallucinations , changed perception and blunting of the emotions. Not all symptoms will be seen in every patient, but there is a considerable similarity to paranoid schizophrenia. This has led some to propose a cannabinoid hypothesis of schizophrenia, suggesting that the symptoms of schizophrenic illness might be caused by an abnormal overactivity of endogenous cannabinoid mechanisms in the brain .
