Does Weed Lower Your Immune System?

In line with the above data, CBD was found to be protective in Theiler’s encephalomyelitis virus (TMEV)-induced demyelinating disease (a viral model of MS) via activating A 2A receptors (120). The effects were thought to be CB 1 - and CB 2 -mediated ones, since both CB 1 (AM251) and CB 2 (SR144528) specific inverse agonists were able to partially prevent the effect of THC in normalizing splenomegaly. Results: how often do you drink alcohol? Anyone who’s familiar with the “beer goggle” effect — the idea that being intoxicated makes you see others as being more attractive than you normally would — will also understand how alcohol use can make a person more inclined to engage in risky sexual behaviors, which can lead to unintended pregnancy and acquiring sexually transmitted diseases, including HIV and hepatitis. More research is needed to understand the connection. Zhang C, Wang S, Yang C, Rong R. Marijuana smoke contains carcinogens, so it may increase your risk of lung cancer too. They can tap into the immune system and alter its effects. Cannabis is a plant that can have many different effects on our bodies, depending on our mood or the strain that you consume.

A study that was published in the Annals of Internal Medicine reported incredible immune system responses to regular cannabis use.

Whenever possible, however, try and make it a point to speak with a physician or other clinical professional regarding the use of CBD oil for immune health. ● Cannabis vs Cancer - Early studies indicate that cannabis compounds can help kill off cancer cells. ● Cannabis Vs Inflammatory Bowel Diseases (IBD) - Recent research suggests that cannabis helps support healthy gut activity. This study emerges as the UK Government has today inched closer to legalising medicinal cannabis in the country after years of pressure from campaigners. A chronic low dose of Δ(9)-tetrahydrocannabinol (THC) restores cognitive function in old mice. The CB2 receptor and its role as a regulator of inflammation. While advancements in science have enabled a greater understanding of our health, getting to the root cause of a chronic disease can be challenging. The HIV/AIDS virus incapacitates the primary defenses of the immune system by attacking collections of certain cells known as CD4 and CD8.

Snorting cocaine damages mucous membranes in the nose, throat, and lungs, which in turn can lead to upper respiratory infections or a susceptibility to these conditions. Upon return to msp, travelers from covid-19 countries say they weren't screened. Other precautions, this happens when lymphocytes see normal, healthy cells as antigens and attack them. T cells develop in the thymus, B cells in the bone marrow. A 2020 study in the journal Digestive Diseases and Sciences builds upon these findings by demonstrating that Crohn's patients who use cannabis are less likely to experience serious complications (such as blood transfusions and abscesses), compared to patients who abstain from cannabis. The levels increased regardless of the amount of marijuana use, although all users in the study had a history of smoking pot several times or more a week. This self-attack is known as "molecular mimicry" and is the root of any autoimmune disease. THC, on the other hand, has shown to be an immune system suppressant only at very high doses but a pain reliever and anti-inflammatory at very low doses. In fact, many important and widely-used drugs to treat autoimmune diseases suppress immune function, so are a benefit to those with disease, but potentially detrimental if taken by those without disease.

Birdsall SM, Birdsall TC, Tims LA. Endocannabinoids and the immune system in health and disease. The observational nature of the study constrained causal inferences. We mentioned it earlier, but there’s significant research showing cannabis can help people with HIV and AIDS. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The researchers found that marijuana triggered the production of a massive number of myeloid-derived suppressor cells — leading to immune suppression and cancer growth — by activating cells that respond to the cannabinoids found in marijuana, researchers said. See our public policy position on marijuana and lung health.

The ECS and Its Ties to the Immune System

The key appears to be in its anti-inflammatory response. Keep reading to see how it works. An in vitro study of human skin cells published in 2020 in the Journal of Dermatological Science found that THC, CBD, cannabinol (CBN), and cannabigerol (CBG) can all inhibit the proliferation of keratinocyte cells, depending on the concentration of the cannabinoids used.

Confirmed marijuana use and lymphocyte count in black people living with HIV. Moore CA, Iasella CJ, Venkataramanan R, Lakkis FG, Smith RB, McDyer JF, et al. Cannabis seems to decrease inflammation in the body by suppressing certain parts of the immune system.

A Study Has Shown That The Total White Blood Cell Count In Cannabis Users Is Higher Among Heavy Users When Compared To Non-users.

The discovery offers a possible explanation of why cannabis smokers have a higher risk of getting infections, says Nagarkatti. J Neuroimmunol. Indeed, CB 1 is generally considered to signal through G αi protein leading to a decrease in the intracellular cyclic adenosine monophosphate (cAMP) level, and activation of the β-arrestin 1 and 2 pathways. Our site is dedicated to helping you find the best CBD products both in terms of quality and value for money. Moreover, TLR and cannabinoid receptor cross-talk (84), as well as novel, “ECS-related” receptors (GPR18 and GPR55) have all been suggested to play a role in the pathogenesis of MS (85), and CB 1 (86–88), but especially CB 2 also emerged as a remarkably powerful and multifaceted future therapeutic target in this disease (88–100).

To even scratch the surface in terms of describing CBD’s potential effects on the body’s immune system, we have to understand at least on a basic level how the endocannabinoid system works. Not only did marijuna help HIV/AIDS patients gain weight, it also had a positive effect on their immune systems over the course of 21 days. Indeed, recent findings showed that cardiac allograft rejection was accelerated in CB 2 −/− mice compared to wild-type recipients. However, this study revealed that even short-term marijuana use can help these important cell groups stay healthy and strong. Yet again, this is an area in dire need of further research.

But researchers also say this finding could lead to new treatments for people with autoimmune disorders. The body’s endocannabinoid system is known to occupy a central role in regulating the immune system. Nagarkatti and his colleagues found that THC fires up the body’s production of myeloid-derived suppressor cells, which are immune system cells that suppress the immune system. There was no available information on the route of administration of cannabis (smoking, ingestion, etc.)

Research exploring the potential of cannabis as an autoimmune therapy is emerging. The plant may decrease chronic pain, inflammation, and spasms associated with some of these conditions. Rheumatoid arthritis, multiple sclerosis, Lupus, PANDAS, and Hashimoto’s thyroiditis are just a few examples of disease state resulting from an immune system gone awry. Little is known about what causes the body to attack itself – possibly a combination of genetic tendencies and environmental toxins or viruses. There is not much research into the effects of secondhand marijuana smoke. Want to stay connected with #SciCommPLOS or pitch an idea for a blog post? Despite these promising findings, data of some other studies argue against the administration of pCBs in infectious diseases. References, eating more fruits and vegetables can keep your immune system strong. Two recent studies support the findings that cannabis could improve immune function for people with HIV/AIDS.

However, sometimes the immune system needs to be suppressed.

Chromenopyrazole, a versatile cannabinoid scaffold with in vivo activity in a model of multiple sclerosis. Fernandez-Ruiz J, et al. The bulk of immune system-related research looks at cannabis’ effect on HIV/AIDS patients. Such is the case with autoimmune disease, in which the immune system begins to attack a patient’s own body. Cannabis modulates the immune system, but is that in the right direction? About 50 million Americans suffer from autoimmune diseases that cause abnormal over-activation, or under-activation, of the immune system.

Simply stated, the ECS can help regulate or vary the properties, tone, and overall function of the immune system.

Living With Mucopolysaccharidoses: Support, Awareness And Research

J Leukoc Biol (2020) 78: However, scientists studying the effects of the ECS on the immune system, neuroinflammation, inflammatory arthritis joint health, and even systemic inflammation have uncovered remarkable benefits from naturally occurring and endogenously produced cannabinoids. Altogether, these data clearly indicate that memory problems can occur on the basis of both overactivation and critical impairment of CB 1 signaling. According to a University of South Carolina study on the effects of cannabis on the immune system, weed smokers are more susceptible to cancers and infections. For this reason, people with HIV/AIDS’ response to cannabis suggests how everyone’s body interacts with cannabis.

The location of the autoimmune attack will vary based on the condition.

Cannabinoids Can Suppress The Immune System

Conventional medicine has mainly responded to autoimmune diseases with drugs that aim to suppress the immune system. A strong and healthy immune system is one that is regularly and consistently fed nutrients. The correct answer to this question? Katz D, Katz I, Porat-Katz BS, Shoenfeld Y.

Molina PE, Amedee A, LeCapitaine NJ, Zabaleta J, Mohan M, Winsauer P, et al. ” We believe when you start something new, it’s best to start slow. A precise quantity of cannabinoids to be ingested can be advised only if taking into account what’s troubling you personally. Multiple sclerosis, for example, is an autoimmune disease that results from the cell-mediated immune system becoming overly active and targeting the body's brain and nervous system as if it were a dangerous antigen.

A too-ready immune system can exacerbate autoimmune diseases. Second, due to the aforementioned “transgenerational” effects (168–171), in an “ideal” clinical study, inclusion/exclusion criteria should also consider “family history” of marijuana consumption. For patients with already weakened immune systems, this means an increase in the possibility of dangerous pulmonary infections, including pneumonia, which often proves fatal in AIDS patients.

For A Weekly Dose Of The Fresh Toast

Cannabinoid-induced apoptosis in immune cells as a pathway to immunosuppression. This has been a topic of interest for a lot of physicians, but what does it really mean? CV Sciences is one of the leading suppliers and manufacturers of agricultural hemp-derived CBD bulk and finished products. You can consume it in oil form either by dropping it directly under your tongue or adding it to food or drink. Rheumatoid arthritis occurs when the immune system attacks cartilage and tissue in the joints.

No matter how you use marijuana, the drug can cause immediate and long-term effects, such as changes in perception and increased heart rate.

Omega-3, in particular, helps to reduce inflammation in the body and is especially useful when trying to recover from the common cold. Very large doses of marijuana or high concentrations of THC can cause hallucinations or delusions. Consuming cannabis can undoubtedly help with many conditions where the immune system is plagued, but to take full advantage of the healing powers of this plant, two factors have to be followed—a personalized regiment of use, and a carefully selected strain (or some other form of cannabis), which has a desirable quantity of cannabinoids in it. Adaptive immune responses deal with specific threats, such as certain disease-causing bacteria. With respect to the “classical” pCBs, beneficial effects of Sativex® (a buccal spray, which contains THC and CBD in a 1: )Modulation of Gut-Specific Mechanisms by Chronic Δ9-Tetrahydrocannabinol Administration in Male Rhesus Macaques Infected with Simian Immunodeficiency Virus: Tweet us at @SciCommPLOS or email us at [email protected]

Moreover, a common dinucleotide polymorphism of CB 2 , resulting in a Gln → Arg substitution (Q63R), which is accompanied by a reduced capability of CB 2 -mediated signaling to suppress T cell proliferation (67), was associated with an increased risk of immune thrombocytopenia (68), and celiac disease (69). This is clear from studies performed with animals, although similar studies in human cells suggest this could also happen in people. Ligresti A, De Petrocellis L, Di Marzo V. Third, purity/quality of the self-administered marijuana, as well as exposure to other illicit drugs, to alcohol (184), or to drugs belonging to the “gray zone,” e. For others who are looking to lose weight, this effect could be considered a disadvantage. While most immune system cells are protective — fighting infections and cancers to keep a person healthy — these cells suppress the immune system, keeping it in check, according to the study.

It is also noteworthy that besides these compounds, ca.

However, extensive studies in test-tubes and in animals have reported the anti-inflammatory benefits of cannabinoids for specific AI conditions like multiple sclerosis and rheumatoid arthritis. On top of these factors, the HIV/AIDS patients that used marijuana were consistently healthier than the patients who didn’t. The study is published in the December issue of the European Journal of Immunology.

There are more than 100 diseases categorized as autoimmune conditions, with some of the more-often-diagnosed conditions including psoriasis, rheumatoid arthritis, lupus, irritable bowel syndrome, and Crohn's disease. With respect to CB 2 , it has recently been shown that loss of homeostatic CB 2 signaling worsened LPS-induced sepsis in mice, whereas activation of CB 2 was proven to be beneficial via reducing leukocyte endothelial interactions, and thereby preventing further inflammatory damage (144). Enhancing endocannabinoid activity has broad therapeutic potential, including the treatment of patients with somatic dysfunction, chronic pain, and neurodegenerative diseases as well as inflammatory conditions, bowel dysfunctions, and psychological disorders. Taken together, pCBs can be considered as multitarget polypharmacons, each of them having unique “molecular fingerprints” created by the characteristic activation/inhibition pattern of its locally available cellular targets (Figure 3) (52). Cannabis users also noted increased drowsiness, improved sense of well-being, and had a considerably higher score in the mental health component of one survey compared to the non-users. "; if (stack2 = helpers.title) { stack2 =, {hash:{},data:data}); } else { stack2 = depth0.title; stack2 = typeof stack2 === functiontype ? stack2.apply(depth0) : stack2; } buffer += escapeexpression(stack2) + ". Int J Oncol (2020) 51: In these instances, it would be absolutely detrimental to decrease inflammation, because the infected cells could roam freely throughout our body, causing additional harm without the inflammation process isolating the threat. The presence of these cells is known to increase in cancer patients, and it is believed that MDSCs may suppress the immune system against cancer therapy, actually promoting cancer growth.

CBD Cartridges: 5 Best CBD Vape Cartridge Brands to Buy

THC and another ingredient called cannabidiol (CBD) are the main substances of therapeutic interest. Moreover, since the FDA does not yet recognize CBD as a medicine, many of the above-mentioned companies are legally obliged to market their CBD tinctures as “nutritional supplements” rather than actual medicinal drugs. It was a helpful ally – that’s all that mattered. THC activated two types of cannabinoid receptor on immune cells, called CB1 and CB2. Frankincense carteri, once you’ve seen how easy it is to make this all-purpose DIY spray, make sure you check out our post Winter Odor-Busting Essential Oil Recipes. Due to the paucity of human studies evaluating the effects of cannabis on the immune system, the committee identified no good- or fair-quality systematic reviews reporting on the health endpoints addressed in this chapter.

The health effects of marijuana are determined in large part by how it's consumed. Lupus can manifest in the skin, digestive system, joints, and the brain. Indeed, in order to overcome these problems, a number of different promising therapeutic opportunities are currently investigated, including, e. Again, researchers found that cannabis smokers had fewer immune-enhancing natural killer cells and lymphocytes, and higher levels of a protein that may promote tumor growth, called interleukin-10. Cannabidiol also slows down T-cell production and suppresses immune system memory, meaning that CBD could cut down on the likelihood of future autoimmune attacks. In these disorders, the immune system strikes the body’s organs, causes pain and can even lead to death. The adaptive immune system has two key mechanisms: In liver cancer, higher abundance of CB1 and CB2 receptor correlated with improved prognosis.

Ultimately, the study found that the cannabinoids reduced the number of infected cells from 30 to 60 percent. However, it should also be noted that long-term cannabis exposure in two patients resulted in reversal of this effect (173). What are autoimmune diseases? Previous research has shown cannabis can reduce cancer treatment side effects such as nausea and sickness, but it could also help to directly fight the disease, the study claims.

Conflict of Interest Statement

Personal interview, June 27th, 2020. Overexpression of cannabinoid receptor 1 promotes renal cell carcinoma progression. How friendly you're feeling could be linked to your immune system., [51] Growth factors and cytotoxic factors may also be released. The endogenous cannabinoid anandamide potentiates interleukin-6 production by astrocytes infected with Theiler’s murine encephalomyelitis virus by a receptor-mediated pathway. Trillions of friendly bacteria living in our digestive systems help to break down foods for absorption into the bloodstream, and synthesize vitamin B and vitamin K. When you inhale marijuana smoke into your lungs, the drug is quickly released into your bloodstream and makes its way to your brain and other organs.

Most of the concern regarding cannabis use revolves around smoking. Acharya N, Penukonda S, Shcheglova T, Hagymasi AT, Basu S, Srivastava PK. An inflammatory response acts as the body’s defence mechanism in case of infection or damage. The study highlights how cannabis is able to mediate its effects through the cannabinoid-1 (CB1) and cannabinoid-2 (CB2) receptors. A dysfunction in the immune system is an underlying cause for HIV/AIDS.

Taking a toll on neuroinflammation. In early studies, cannabis was shown to affect both neurogenesis and neurodegeneration - the new growth and degeneration of nervous tissue in the brain, respectively. Likewise, another study also showed that chronic THC administration did not increase viral load or aggravate morbidity; in contrast, it could actually ameliorate SIV disease progression, via retention of body mass, and attenuation of inflammation (155). Last, but not least, transient administration of the CB 2 inverse agonists AM630 (10 mg/kg) or JTE907 (3 mg/kg) during immunization was found to improve antigen-specific immune responses in young and aged mice through the upregulation of immunomodulatory genes in secondary lymphoid tissues (149). Nearly all parts of the plant make up marijuana, including the leaves, stem, flowers, and seeds. This occurs when the body’s B-cells produce specific antibodies to seek out and destroy the dangerous pathogens. Although regular heavy drinking is clearly the worst for your immune system, binge drinking can also knock out your immune system temporarily.

Digestive System

CBD2 receptors are found throughout the body – including in bones, skin, and the spleen – and the immune system. (Acomplia and Zimulti), which was applied as a potent anorexigenic agent for a few years in Europe, but was then retracted from the market (180). Moreover, administration of THC and activation of CB 1 were shown to lead to memory impairment, most probably due to the activation of the recently discovered, mitochondrially expressed subset of the receptor (175, 176), suggesting that extracellularly restricted CB 1 agonists may be devoid of such side effects. According to new research, cannabinoids may have an important balancing role that allows the immune system to function at maximum efficiency.

T-cells, B-cells, and antibodies of the immune system regulate the adaptive immunity of our immune system.

Cannabis & HIV

Interaction between cytokines, cannabinoids and the nervous system. Smoking marijuana can harm more than just the lungs and respiratory system—it can also affect the immune system and the body's ability to fight disease, especially for those whose immune systems are already weakened from immunosuppressive drugs or diseases, such as HIV infection. Patients with Crohn’s disease taking medical marijuana reported that their symptoms were less severe and occurred less often, and in some cases went into remission.

Autoimmunity (AI) is an "attack on self", where the immune system gets triggered and thinks that the body's healthy tissues are invaders. The concept that positive modulation of cannabinoid signaling could be helpful in transplantation is supported by multiple pieces of evidence. Smoking marijuana reduces the body’s ability to resist infections from viruses, bacteria, fungi, and protozoa. This is perhaps true; many reputable scientific studies support the conclusion that cocaine, heroine, alcohol, and even cigarettes are more dangerous to the user’s health than marijuana. Cannabis is an extremely versatile plant, but it all comes down to each patient’s unique situation. This involves the use of T-cells which seek out and destroy foreign antigens on their own by inducing apoptosis, or “programmed cell suicide,” in the foreign antigen. As such, the ability of cannabis to suppress the immune system and its powerful anti-inflammatory properties can help people suffering from health issues that are related to high levels of inflammation. Active chemical compounds from cannabis are able to trigger apoptosis in cancerous cells.


The research, published in the European Journal of Immunology, reveals why cannabis users are more susceptible to certain types of cancers and infections. Other studies have shown that regular cannabis use can increase white blood cell counts in immunodeficiency disorders such as HIV, suggesting an immune-boosting effect. It is important to note that adaptive immunity regulates our body’s recognizing, attacking, and cleaning up, cancer cells. And while this is good for relieving pain, it’s not necessarily good for your immune system. Inflammation helps trap and isolate damaged parts of the body, preventing the spread of infection. Preclinical studies show that triggering CB2 receptors can suppress immune response, which can be beneficial for those suffering with AI. Newsletters, this includes monocytes and macrophages (that attack and absorb foreign bodies), as well as cytokines and chemokines (secreted by immune cells to neutralize agents of infection via multiple mechanisms, typically resulting in inflammation). According to Dr.

Today, they're also gaining popularity for their positive effects on the human immune system. Kaushansky, R. Exposure of adolescent mice to delta-9-tetrahydrocannabinol induces long-lasting modulation of pro- and anti-inflammatory cytokines in hypothalamus and hippocampus similar to that observed for peripheral macrophages. In line with these data, BCP suppressed motor paralysis and neuroinflammation in EAE by inhibiting microglial cells, CD4+ and CD8+ T lymphocytes, as well as protein expression of proinflammatory cytokines. Autoimmune diseases and medical marijuana research, depending on what autoimmune disease you have, you may need to see a separate specialist, such as:. Autoimmune conditions more commonly affect women than men.

Modulation of HIVGP120 antigen-specific immune responses in vivo by Δ9-tetrahydrocannabinol. There is a need for more large-scale, scientific studies of medical cannabis. Sufficient sleep: Additional approaches one can take to lower inflammation:
