Does Weed Marijuana Kill Brain Cells?

The biggest risk of weed is that it will cause the onset of psychosis in susceptible individuals. Some people have a type of mind and of developmental trauma such that they are just on the edge of developing a schizophrenic type of mind. Many studies have shown that weed can be the trigger that pushes them over the edge into full-blown schizophrenia with attendant hallucinations. This claim is however controversial because it’s not clear if the weed is causing schizophrenia or if the person is trying to medicate symptoms that are already present by smoking weed and also cigarettes. Chronic marijuana use can lead to marijuana use disorder and increases the risk of progressing to other drugs. Along with addiction, marijuana use can negatively affect your mental health and quality of life.

Available research offers some insight into the short-term effects of drug use. However, it is difficult to draw definitive conclusions regarding the long-term effects of drug use. Keep reading to learn more about what current studies have to say about marijuana’s short- and long-term effects on the brain.

• During working memory tasks, the researchers found heavy cannabis use appeared to reduce brain activity in certain areas of the brain (dorsolateral prefrontal cortex, dorsomedial prefrontal cortex and anterior insula).
• They do this because they are made up of special chemicals that change the way the current chemical cycles in the brain work.
• Endocannabinoids have a range of purposes in your body and interact with specific receptors in your brain and nervous system.
• However, cumulative exposure didn’t appear to affect processing speed or executive function.
• Marijuana can have different impacts on the brain, both in the short term and over the long term.
• Inhaling these compounds and extremely hot smoke depletes oxygen in the blood and brain and kills brain cells.

Synthetic

Because they act on the same receptors as natural marijuana, they lead to the signature euphoric high. However, they bind to the receptors with a higher strength so that high isn’t always euphoric or even pleasant. As a group, they attach more tightly to the cannabinoid receptors, sometimes producing more serious side effects. SCBs are illegal substances meant to be similar in chemical structure to naturally growing marijuana in order to cause similar effects. Often, people think it’s a safe alternative to marijuana but, in reality, synthetic marijuana is frequently stronger and unpredictable. National Institute on Drug Abuse (NIDA) researchers established that there are a lot of questions concerning the long-term effects of marijuana.

The relationship between cannabis and brain cells is complex, and its impact on brain function depends on various factors, such as the specific cannabinoid, dosage, and individual susceptibility. To understand the impact of cannabis on brain cells, it is necessary to examine the endocannabinoid system (ECS). The ECS is a complex cell-signaling system throughout the body, including the brain, and is responsible for maintaining homeostasis or balance in various physiological processes. It plays a crucial role in regulating mood, memory, appetite, and pain sensation. Studies haven’t conclusively shown that cannabis, in any form, directly kills brain cells. However, heavy and prolonged use can affect brain development in adolescents, whose brains are still maturing.

Drug & Substance Abuse FAQs

The body naturally produces endocannabinoids, which are similar to cannabinoids. Both cannabinoids, such as THC, and these natural endocannabinoids, bind to the same receptors in the brain. 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. If users decide to drive while high, they can endanger their lives and the lives of others.

Other studies within this review also demonstrated no glutamate how many brain cells does weed kill effect from cannabis intake across different human brain regions. Variations in study design, such as imaging modality and parameters, prior cannabis exposure of participants, and cannabis products used, were noted among the studies. More research is needed to determine the true effect of cannabis on glutamate levels in the living human brain. Observational studies were not meta-analyzed due to the insufficient information provided regarding the type of cannabinoids and the amount of doses used by participants in these studies. It was difficult to ascertain the quality of these studies making it difficult to proceed with any statistical analyses.

Curious About Cannabis?

• First, it was among the first large, longitudinal (long-term) studies to assess marijuana use and cognitive functioning.
• Many have questions regarding how cannabis may affect different ailments, including those related to dementia.
• Today, as we continue to explore the plant’s impact on the human brain, it’s essential to recognize the deep historical context from which our current perspectives emerge.
• Her passion and purpose as a clinician are to help individuals find their voice, purpose, and motivation through their recovery.
• Research shows that frequent cannabis use during adolescence can disrupt the normal development of brain cells, particularly in regions responsible for decision-making, memory, and learning.

When you use marijuana, the active ingredient tetrahydrocannabinol (THC) enters your bloodstream and is carried to your brain. The relationship between humans and cannabis is ancient, stretching back thousands of years. Its roots lie deep within various civilizations, where it served a myriad of purposes – from religious rituals to rudimentary medicine.

Exposure to cannabis

So, when Hollywood shows that stoner trope of someone waiting for a stop sign to turn green, it turns out that it is something that using marijuana can cause. The special circuit that the impact of the cannabinoid neurotransmitters, or messengers, can actually also trigger the brain’s reward system. This system can be and sometimes is activated or altered by more than just substances that get misused. The question “Does weed kill brain cells?” has been debated for years, with research offering mixed results.

Alcohol, nicotine, and marijuana affect different neurological systems, and as a result have different long-term effects in the brain. A 2017 report cited moderate evidence that using marijuana as an adolescent is a risk factor in the development of problem cannabis use later on. The detailed study characteristics of included RCTs and observational studies are presented in Tables 1 and 2. Authors BU and VS screened titles and abstracts, resulting in 42 eligible articles for full-text screening.

We provide help for individuals struggling with cannabis use disorder and other substance use disorders in the counties that surround Chicago as well as the city itself. Because weed affects more than just your brain, it’s also important to know about the other side effects of weed use before you decide to try it. Edibles are also usually isolated only to contain THC or CBD, and sometimes both. That may mean that those chemicals interact differently with your endocannabinoid system because they are isolated from other cannabinoids that might have other effects. With weed, also called cannabis or marijuana, use becoming legal in some places, there are many more questions about smoking weed, whether it’s safe, and whether there are any permanent consequences to regular weed use.

Whether you want to stop using weed because you don’t want to deal with its negative consequences and side effects, because you no longer like how it feels, or because weed is interfering with your normal life, you can do it. When you eat an edible, you also use a different route to get it into your bloodstream and brain. Your liver converts the THC in the edible into a different, more potent, form of THC, which may increase the impact of the THC in your brain. One of the biggest differences is that edibles take longer to kick in and may also last longer in your system.

Cannabis users who visited the emergency room or were hospitalized were up to four times as likely as people in the general population to be diagnosed with dementia within five years, according to a large new study. Some of these benefits come from cannabidiol (CBD), the chemical part of the marijuana plant that doesn’t produce mind-altering effects. What’s well known is that the signature high from marijuana comes from a psychoactive element known as tetrahydrocannabinol (THC). However, Gowin mentions their research also suggests that abstaining from using cannabis before doing a cognitive task could help to improve performance. “People need to be aware of their relationship with cannabis since abstaining cold turkey could disrupt their cognition as well. Marijuana can have different impacts on the brain, both in the short term and over the long term.

It is therefore important to understand recreational cannabis use should be limited to adults. As a person ages, they naturally lose neurons (brain cells) in the hippocampus. Heavy marijuana use may speed up this process, making it difficult to learn new information. The amount of damage caused may depend on the age you are first exposed to marijuana and how long you use it.
