Can Weed Enhance Your Brain

Does Cannabis Kill Brain Cells? – Weedwise

If youre a big Kool-Aid drinker when it comes to the claimed negative effects of marijuana, you might want to skip this section. It might just shatter your existing biases. Believe it or not, there is quite a bit of evidence that suggests smoking pot can actually boost brain processes!

Weeds beneficial effects center on neurotoxins like aspartame and fluoride. These chemical compounds can cause your nerve cells to malfunction. Your nerves may not be able to convey the information they carry at peak efficiency and effectiveness.

There are certain compounds found in cannabis which helps protect the brain from neurotoxin damage. These compounds also called cannabinoids have also been shown to be chemical antioxidants. They help shield your brain cells from damage.

In a study released in 2015, CBD was shown to reduce the levels of a neurotoxin thats been linked to the onset of Parkinsons disease. This neurotoxin has been shown to act as some sort of trigger to a nervous breakdown .

Additional research suggests that THC can cut down on the buildup of amyloid plaque and reduce inflammation in the brain. These two processes often work hand in hand to produce Alzheimers disease .

Finally, this same study showed that pot compounds may help promote the regeneration of brain cells by reducing the effect of neurotoxins.

How Many Brain Cells Does Weed Kill


Humans have a long history with the cannabis plant but up until a few decades, all of the known benefits and effects were based on anecdotal evidence. With the legalization of cannabis, whether in medical form or for recreational use, the opportunities for examining its effects have significantly broadened.

In the past, due to the lack of accurate scientific information that could provide an adequate understanding of its effects, there were a lot of misconceptions about cannabis. There is still so much to discover about both the positive and negative effects of weed and all the ways it can be used, but today well talk specifically about its influence on cognitive function and behavioral health.

Theres a common belief that marijuana kills brain cells, but in reality, there isnt a ton of research on whether it can negatively impact brain function. In fact, the results are pretty conflicting and this is what well be looking at today.

Top 5 Important Things To Take Away

  • Weed doesnt kill brain cells.
  • Weed causes temporary forgetfulness. It can cause a drop in IQ points.
  • Weed may cause susceptibility to psychosis for people who start smoking as children.
  • Weed can increase the risk of cardiac events in the period just after smoking and this can affect the brain
  • Weed is not known to cause excitotoxicity in the neurons or overdose fatality

    The Argument That Cannabis Positively Changes The Brain

    Some research actually creates a valid argument for cannabis positively impacting the brain, specifically by igniting the process of neurogenesis or the creation of neurons in the brain. This study says, A body of data indicates that cannabinoid ligands control cell genesis in the adult brain, regulating cell proliferation and overall neurogenesis in the mammalian brain. According to this same study, the cannabinoid system plays a central role in adult neurogenesis processes in the hippocampus and lateral ventricles. Indeed, cannabinoids have clear modulatory roles in adult neurogenesis, probably through activation of both CB1 and CB2 receptors.

    Another study reads, Recent studies have shown that THC can promote neurogenesis, restore memory, and prevent neurodegenerative processes and cognitive decline in animal models of Alzheimers disease. CBD also improves cognition in preclinical models of cognitive impairment in schizophrenia. To reconcile these seemingly contradictory results, it has been suggested that THC modulates memory and cognition in an age- and dose-dependent manner.

    How Does Weed Impact Your Brain Cells And Body

    Does Weed Kill Brain Cells?

    With weed being illegal on a federal level there is a significant lack of research into the effects of weed on the mind and body. There are some indications that some users may experience some significant effects as a result of their weed use. The specific way in which weed impacts the mind and body of the user, however, will greatly depend on the user and many factors of their biology and physiology.

    From birth, our bodies are designed to both use and produce endogenous forms of the cannabinoid compounds found in weed. This means the human body creates its own cannabinoids for a range of purposes, and it also means that the human brain is also designed to have cannabinoid receptors to facilitate the effective use of cannabinoids.

    Weed is unique among many drugs in that it has its own receptors in our brain, and it does not have to interfere with other systems in the body. This also means that when a user takes weed, it is likely to cause similar effects as when the brain interacts with the natural endocannabinoids present in our bodies.

    In some research, those who used weed were assigned a list of vocabulary words to memorize, as were a group of people who had not used weed. The results indicated that when compared to the weed users, the non-users were able to recall one more word on average. This particular study showed a strong correlation between the use of weed and the way that the brain is able to receive, store, and retrieve information.

    No Oxygen = Brain Cell Death

    Whats more, that level of smoke was ludicrous. As one physician told Congress in the 1970s, the equivalent of a small-lunged rhesus monkey exposed to the much pure cannabis smoke would be a human being sucking down over one hundred joints a day for six months.

    And, importantly, scientists could not replicate the results. Even when using better and more accurate forms of measurement. As MIT notes: The work was never replicated and has since been discredited by a pair of better controlled, much larger monkey studies, one by Dr. William Slikker of the National Center for Toxicological Research and the other by Charles Rebert and Gordon Pryor of SRI International.

    In no other study did scientists record cell death after or during cannabis smoking. The work was discredited and tossed into the dustbins of the annals of science. So does cannabis kill brain cells? No. So why then do we still hear about it today?

    The best explanation for the tenacity of this lie is that it helps push a narrative that anti-cannabis activists support. Today, we know that the active ingredients in cannabis are cannabinoids, which react in healthy ways with the bodys endocannabinoid system.

    Cannabinoids As Antiemetic Agents

    The ability of THC and the synthetic cannabinoid nabilone to control the nausea and vomiting associated with cancer chemotherapy is one of the few well documented medical applications for these drugs . THC and nabilone were approved for medical use in the USA, although neither drug has found much utility. The narrow window between the antiemetic dose and that causing unwanted psychic effects made these drugs difficult to use. The advent of serotonin 5HT3 receptor antagonists as new and more powerful antiemetic drugs that were free of unwanted psychic effects during the 1980s also made the cannabinoids less attractive.

    Studies in experimental animals have confirmed that the antiemetic effects of cannabinoids are mediated through CB1 receptors , and in some susceptible species the CB1 antagonist rimonabant is emetic, an effect that can be blocked by THC or WIN55,2122 .

    What Pot Really Does To The Teen Brain

    How much should we worry?

    Celia Krampien

    American parents have been warning teenagers about the dangers of marijuana for about 100 years. Teenagers have been ignoring them for just as long. As I write this, a couple of kids are smoking weed in the woods just yards from my office window and about a block and a half from the local high school. They started in around 9 A.M., just in time for class.

    Exaggerating the perils of cannabisthe risks of brain damage, addiction, psychosishas not helped. Any whiff of Reefer Madness hyperbole is perfectly calibrated to trigger an adolescent’s instinctive skepticism for whatever an adult suggests. And the unvarnished facts are scary enough.

    We know that being high impairs attention, memory and learning. Some of today’s stronger varieties can make you physically ill and delusional. But whether marijuana can cause lasting damage to the brain is less clear.

    A slew of studies in adults have found that nonusers beat chronic weed smokers on tests of attention, memory, motor skills and verbal abilities, but some of this might be the result of lingering traces of cannabis in the body of users or withdrawal effects from abstaining while taking part in a study. In one hopeful finding, a 2012 meta-analysis found that in 13 studies in which participants had laid off weed for 25 days or more, their performance on cognitive tests did not differ significantly from that of nonusers.

    Marijuana Kills Brain Cells Myth

    I guess you can tell where I stand on this issue just by looking at the subheading above. The idea that weed kills brain cells originated in the 1970s and 1980s. The pseudoscience making the rounds at that time, however, traced a lot of their origins from the fake research conclusions popularized in the 1930s.

    The 1970s was a crucial time in terms of American marijuana policy because this was the beginning of Americas war on drugs . As anybody with more than two brain cells can tell, the war was a very expensive failure. It ended up with a lot of people going to jail, and the drug problem remaining uncontrolled and unabated.

    Since that time, anti-marijuana activists kept repeating the idea that weed irreparably harms the human brain. While marijuana does produce effects that are very noticeable in the short-term, when compared to alcohol or other drugs, it doesnt have the same negative long-term effects. Unfortunately, websites like the Drug-Free World continue to spread the lie that weed destroys brain cells .

    We also wanted to let you know about CBD. If you didnt know already, CBD products allow you to enjoy the medicinal benefits of marijuana without the head high, bloodshot eyes or lazy stoner sensation.

    Lets go back to the topic of smoking marijuana.

    Pop culture is always shaping our lives, mindsets, and thoughts. Whether we like it or not, some of our strangest prejudices come from the silver screen. One such stereotype is that all stoners are dumb or slow.

    Take the movie Pineapple Express, for example, it was a 2008 hit film that made more than $100 million at the box office. It is touted as one of the best buddy stoner films of all time. Its led to a particular type of marijuana known as, you guessed it, Pineapple Express to be one of the most popular strains of all time.

    The film is renowned for its silly and over the top comedy including zingers like:

    Its like killing a unicorn, with like, a bomb

    Its out bro! Monkeys out of the bottle

    These silly lines and other comedic effects throughout the film are all representations of stoners and those who use marijuana regularly. Of course, this isnt the only such film that depicts drug use in this light. There are tons of Hollywood hits that display drug use from cocaine to meth to alcohol and back again.

    As for weed, its usually displayed in a light of fun, happy-go-lucky giggle fits, and some really, really dumb sounding one-liners. Other common tropes of the stoner include tie-dye shirts, hippie styles, and a laid back attitude. We also often see these people as being a little bit slower than the rest of the cast.

    Take Action & Empower Yourself



    While the conclusions of new research may differ, they agree that overuse of Marijuana, or any drug, is not healthy. While moderation applies to everything in life, drugs require slightly more moderation because of their tendency to cause adverse health effects. Results seem to suggest that moderate use even during development may have no detrimental effects, but waiting until a less sensitive time in mental development is advisable.

    How Marijuana Affects The Reward System

    Similar to other drugs, chronic marijuana use can lead to changes in your brains reward system. As your brain adjusts to the high amounts of dopamine released by marijuana, it becomes less sensitive to other stimuli.

    Increased dopamine is associated with pleasurable feelings, which can make it more difficult to stop using marijuana. Continued use can increase tolerance and eventually lead to dependence and addiction, which may require treatment.

    How Does Thc Interact With Brain Cells

    The primary active ingredient in Marijuana is THC. This compound stimulates receptors in the brain and facilitates the release of dopamine, the reward chemical. Receptors throughout the brain are able to bind with THC in order to achieve the psychological effects of a Marijuana high. Brain scans show that Marijuana primarily interacts with:

    • The Cerebral Cortex: higher order thinking
    • The Hippocampus: long-term memory, short-term memory, spatial memory
    • The Nucleus Accumbens: reward system
    • The Cerebellum: voluntary movement and sensory management

    Is It True That Smoking Weed Kills Brain Cells

    Studies suggest that can cause cognitive deficits in adults who have used marijuana in childhood. However, the extent of impairment seems to depend on when you started using, how long youve used, and how much youre using now.

    According to the NIH National Institute of Drug Abuse, researchers who study the link between marijuana and reduced IQ scores do not always get the same results. Therefore, their findings to date are inconclusive.

    Its difficult to prove that marijuana causes IQ score deficiency when so many variables come into play. A host of other factors can reduce IQ scores just as easily as marijuana.

    Lower scores can result from early childhood trauma, poor quality of education, genetics, age of initial cannabis use, and duration of use to name just a few.

    Although there may be a correlation between lower IQ scores and marijuana use, theres just not enough information at this time to reliably ascertain whether marijuana lowers childrens IQ scores or not.

    • Does Marijuana Kill Brain Cells? How Weed Affects Cognition

    What are the side effects that come to mind when you think of marijuana use? Most likely giggling, slowed speech and movements, and a sudden craving for snacks. This bumbling stereotype might lead you to believe that marijuana makes you dumber, but the scientific consensus seems to be that marijuana does not kill brain cells. This doesnt mean that marijuana is harmless, however.

    While weed doesnt directly result in the death of the neurons the way that stress, head trauma, or other types of substances can, it can still go on to cause significantand long-lastingdamage. This brain damage can lead to permanent side effects such as impaired memory, mental illness, and in the case of adolescents and their still-developing brains, a lower IQ.
