Similarly, there was less branching of blood vessels, which would have the same effect. The study, which appears in Nature Communications, finds that the deepest sections of the brain are most significantly affected. Vitamin B12 is available in multivitamin supplements, B-complex supplements https://rehabliving.net/salvia-drug-overview-is-it-dangerous-and-or/ and supplements containing only B12. The amount of B12 in supplements can vary widely, from 500 micrograms to 1,000 micrograms. “The most important thing when looking at a vitamin B12 supplement is the dosage to ensure that it is one that is appropriate for you,” says Saari.

Vitamin B12 Deficiency

Genetic factors may also contribute to cognitive decline, as suggested by a longitudinal twin study from 2016. Next, the results suggest that marijuana use during adolescence may have an irreversible effect on adolescent brain development. The researchers reported an association between ongoing marijuana use and cognitive decline.

#2 Weed Can Stunt Young People’s Brain Development

They studied levels of nerve growth factor (NGF) in a large group of schizophrenic patients who abused cannabis, showing that cannabis abusers had significantly higher serum NGF levels than nonabusers or controls. Since NGF is released after neuronal damage, they concluded that the increased serum NGF could be evidence of cannabis induced neurotoxicity. However, this study needs further replication and correlation to direct effects on brain tissue. As recreational marijuana use becomes legalized throughout the US, many people now wonder how marijuana 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 (also known as brain activity).

The Cannabinoid type 1 and CB1 receptors are connected to the brain’s nerves that play a role in memory, mood, pain regulation, and appetite. Regularly assess how you feel, both mentally and physically, after consumption. Through ongoing research, scientific understanding of cannabis and its effects on the brain is continually evolving. Stay updated with the latest findings and consult your healthcare professionals to make informed decisions. Especially for newbies, starting with a low dose and gradually increasing it is best.20 Don’t use more until you know how the dose affects you.

1. The hypothesis that cannabis directly causes neurotoxic damage to brain structures making individuals more vulnerable for psychosis was tested by Jockers-Scherubl et al. [112].
2. CB1 receptors have the inhibitory action on cAMP production which is facilitated by the activation of adenyl cyclase inhibitor subunit of G proteins (Gi/0 proteins).
3. In addition to the above symptoms, synthetic marijuana can be addictive to individuals who take it.
4. Three biomedical literature databases, PubMed, Google Scholar, and ScienceDirect were searched up to July 2019.
5. From these studies we can conclude that among the 107 neurovascular cases, almost 84% were ischemic stroke related to cannabis or cannabinoid use (both natural and synthetic).
6. They also note that regions of the brain involved in Alzheimer’s are particularly susceptible to age-related changes in vascular function, which may help explain why cell death occurs in these areas.

Cannabis and the brain: Recent studies shed new light

Likewise, heavy cannabis use has negative social, academic and future functional consequences on young people who are preoccupied with its use. It is known that heavy cannabis use is common among people with schizophrenia and also thought to lead to an elevated risk for schizophrenia. The question is whether there is currently enough evidence to suggest that there are detectable brain anomalies occurring as a consequence of cannabis use that lead to this increased risk of psychosis and schizophrenia. Exogenous cannabinoids such as CBD and nabilone are also found to have therapeutic activity in psychiatric disorders including schizophrenia, posttraumatic stress disorder (PTSD) and general and social anxiety (Cohen et al., 2019). Although cannabinoid-based drugs have shown some therapeutic activities against neurological and psychiatric disorders the effect of cannabis on the neurological system cannot be denied.

Despite having serious effects of marijuana in human health, its use has been legalized in Canada and different states of USA. The Canadian Parliament passed Bill C-45, the Cannabis Act to legalize and regulate the production, distribution, and consumption of cannabis on June 19, 2018, and its legalization started effective from October 17, 2018 (Crepault, 2018). In case of US, marijuana use has been approved in 34 states for medical purposes (State Medical Marijuana Laws, 2019) and in 10 states for recreational purposes (Marijuana Overview, 2019). However, using cannabis later in life (age 50 and over) appears to have only a moderate impact on cognitive functioning, including on memory. These modest declines are not fully understood, and there is a lack of high quality research in this area. Research shows that young, frequent users of cannabis have thinner temporal and frontal cortices, which are both areas that help process memory functioning.

As a result, cannabinoids can alter normal brain functioning, causing a number of negative mental and physical effects. One such effect may be memory loss; researchers have shown that THC can affect the function of the hippocampus – the brain region responsible for forming memories. Nevertheless, there must be some biological explanation for the presumed increased risk for psychosis among adolescent cannabis users and yet a lack of epidemiological evidence for an overall increase in psychosis in decades when cannabis use rose in specific geographic regions. To add to the confusion and contradictory results, a 2018 study on rats showed neurogenesis when exposed to THC or increased the growth of new brain cells. However, some differences between acute and chronic exposure may reinforce that chronic use has different and potentially more harmful effects than a single or occasional use. People who smoke or use marijuana regularly may experience short-term memory loss.

Research has shown that vitamin B12 plays several essential roles in our health. The Recommended Dietary Allowance (RDA) of vitamin B12 for adults 19 and older is 2.4 micrograms per day. However, if you are pregnant or lactating, the amount increases to 2.6 and 2.8 micrograms, respectively. Read about a study that has uncovered the clearest picture to date of the CB1 receptor. He is the author of numerous books, including From Bud to Brain and Marijuana on My Mind. Ocean Recovery has sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations for our references.

This region is responsible for information processing, memory, and decision-making in the brain. Although it is increasingly being legally accepted in many parts of the world, the long-term effects of marijuana are still not fully understood. In recent years, researchers discovered that one cannabinoid receptor called CB1 is located in the mitochondria of nerve cells. Mitochondria are referred to as the “powerhouses” of cells, as they convert the sugar, fat, and proteins we get from food into energy that cells need to function.

These changes all work together to make the brain much more susceptible to hypoxia — a lack of oxygen. Synthetic marijuana, like marijuana, affects the brain by binding to the cannabinoid receptor type 1 (CB1), which is found in both the central and peripheral nervous systems. Synthetic weed binds to CB1 receptors more strongly than THC, making it more potent in the brain.

Tetrahydrocannabinol (THC) is marijuana’s primary psychoactive ingredient, and it attaches to the brain’s cannabinoid receptors (officially known as Cannabinoid receptor type 1 or CB1). These receptors connect to nerves in the brain which govern memory, appetite, pain regulation, and mood. Using marijuana can cause damage to brain cells and result in a number of concurrent symptoms throughout the body. Vitamin B12 is a water-soluble vitamin that contains the mineral cobalt, so is sometimes called cobalamin.

The probandwise concordance rates in Kendler et al. [43] were 48.5% for MZ, 26.2% for DZ same-sex twin pairs and 22.6% for siblings. The non-specificity of the genetic liability suggests that the search for particular liability genes should cover classes of genes with shared effects for non-specific drug abuse, such as on the dopaminergic pathways or on response to neurotoxicity. The sex differences in familiality are not substantial, but if anything suggest adderall higher familial tendency in females, although females have not been studied as extensively as males. Ultimately genes uncovered may be found to influence common pathways in the brain for biochemical or structural alterations or both. Interestingly, all the cannabis users do not experience cognitive impairment which clearly suggests the impact of genetic vulnerability on detrimental effects of cannabis (Blanco et al., 2016; Levine et al., 2017; Hasin, 2018).
