cbd oil for prostate inflammation

Using cannabis in prostate cancer patients

In our hospital’s daily practice we notice the popular use of cannabis oil in prostate cancer (PCa) patients. As a nursing specialist for urology, I have even met patients who are so convinced of the curative benefits of cannabis oil in treating prostate cancer that they replace standard treatment with the use of cannabis oil.

These patients include those who have localised prostate cancer where active surveillance is followed, those with biochemical recurrence after treatment, and patients with metastatic PCa. I have always wondered whether cannabis oil could indeed be a cure for prostate cancer. Unfortunately, I do not see in practice the desired beneficial effect and the PSA values continue to rise. To find some answers, I did a search in scientific literature.

Cannabis, a very easy plant to grow, has been used for centuries for its medicinal properties. The oldest known document about cannabis use originates from the Chinese emperor Shen Nung in 2727 B.C. It suggested that cannabis has a neuron-protective effect. The Egyptians used cannabis to treat glaucoma and as an anti-inflammatory agent (inflammation of the eyes, fever). Cannabis was even used in obstetrics (mixed with honey) and the mixture was applied in the vagina to “cool” the uterus. In the Old Testament, there is also an account of God instructing Moses to make a holy anointing olive oil-based “Kaneh Bosm.”

Cannabis contains more than 400 chemical components 80 of which contain cannabinoid components and 200 non-cannabinoids components. For medical purposes, cannabinoid substances such as THC (Delta-9-tertrahydrocannabinol), CBD (cannabidiol) and non-cannabinoid substances such as terpenoids and flavonoids are relevant.

Medicinal cannabis must be distinguished from recreational cannabis which is used to achieve a psychotomimetic state of ‘high’. Cannabis strains used for recreational purposes contain a higher THC and lower CBD ratio than cannabis for medicinal use. Usually two cannabis plants are used: cannabis sativa which has a higher THC concentration and cannabis indica which has a higher CBD concentrate. The flavonoids are known for their antioxidant and anti-inflammatory effects. The terpenoids are resins (oil) with a strong odour.

In the 1990s, the endocannabinoid system (ESC) of the body was discovered by Raphael Mechoulam, an Israeli professor of medical chemistry. The endocannabinoid system, a central regulatory system, is the body’s largest receptor system and is important to maintain the homeostasis of the body.

Human beings produce their own cannabinoids (endocannabinoids) according to need and are not stored in the body. Like endorphins, the human body produces endocannabinoids in response to activities such as physical exercise (the high of runners might be due to endocannabinoids, not endorphins!).

Cannabinoid receptor type 1 (CB1) is mainly found in the brain, and also in the lungs, the reproductive organs, etc. Cannabinoid receptor type 2 (CB2) is usually located in the immune system and in the bones. THC mainly works on CB1 receptors, CBD on CB2 receptors.

In vitro studies with THC have shown that cannabinoids affect migration, angiogenesis and apoptosis (programmed cell death) of cancer cells, but each type of cancer appears to respond differently to the effect of exogenous cannabinoids. Many types of cancer cells have a higher concentration of CB1 and CB2 receptors.

Use of cannabis in cancer

– Pain: Cannabinoids have been used for centuries to lessen pain. Historical texts and old pharmacopoeia noted the use of cannabis for menstrual cramps, pain during childbirth, and headaches. Studies have shown that the cannabinoids have no effect on acute pain and post- operative pain. Two placebo-controlled studies with a cannabis extract showed modest benefits when using cannabinoids in addition to opioids and other adjuvant pain-killers in cancer patients with chronic pain. However, the effect of cannabinoids in chronic neuropathic pain was clearly demonstrated in 29 randomized studies.

– Nausea and vomiting: An initial study in 1975 showed a beneficial effect of THC on nausea induced by chemotherapy. Subsequently, two systematic reviews showed benefits of cannabinoids in nausea and vomiting due to chemotherapy, but most studies were observational or uncontrolled.

– Stimulation of appetite: Cannabinoids seem to have only a modest effect in cancer patients with cachexia. More promising results were seen in studies in the population without cancer.

– Pre-clinical studies (in vitro = cells in laboratory and in vivo = in mouse model) have shown the antiproliferative, anti-metastatic, anti-angiogenic and pro-apoptotic effects of cannabinoids in various malignancies (lung, glioma, thyroid, lymphoma, skin, pancreas, endometrium, breast and prostate). Even if an identified substance in vitro / in vivo appears to have a beneficial effect on a disease, it is important to realise that only one in 5,000-500,000 substances obtain a registration and becomes available to the patient (after 10-16 years of different study phases). Cannabis has never been clinically studied as a treatment for malignancy.

On the Internet, patients can get a lot of information about the curative effect of cannabis oil on prostate cancer but this information extrapolate the results of pre-clinical work to possible effects in people without any factual evidence. I often see patients in the doctor’s office showing me a website where it has been proven that cannabis oil can cure prostate cancer, which is obviously their own interpretation. In my view this can be a misleading message even though the website does not explicitly provide false information. The website [See figure below] shows information which is based on a study published in the British Journal of Cancer. This is correct, but the website “neglects” to mention that this is a publication of an in vitro study. The patient might not even know what an in vitro study is and is not aware that there are no studies on humans yet to prove this.

A challenge for the caregiver can be that the patient is convinced that we as healthcare practitioners work together with the pharmacists, and that we do not wish to carry out clinical trials (unfortunately, I hear that very often). We can hardly persuade patients that this is not true.

It is also important that we inform the patient about the possible interactions of cannabis oil with certain regular medications such as Coumarin (this blood thinner interacts with cannabis oil, leading to an increase of the INR and a greater risk of bleeding!). There are different types of cannabis oil available, such as CBD and THC oils with different concentrations which makes it difficult for patients to make a choice.

Conclusions:
• There is no proof of cannabis oil as cure for prostate cancer;
• It is important not to be prejudiced or judgmental against patients who use cannabis oil;
• Listening to the patient’s view can be helpful since the patient often confides to the nurse rather than to their physicians;
• Avoid persuading patients not to use cannabis oil, but try to convince them of the need to follow a regular treatment combined with cannabis oil;
and
• Consider adverse interactions between cannabis oil and certain medications and inform your patient about these.

Can You Take CBD Oil for Enlarged Prostate & Other Prostate Issues?

Cannabidiol (CBD) has developed a dedicated following thanks to its perceived effectiveness against anxiety, epilepsy, localized pain, and other conditions. Using CBD oil for issues such as an enlarged prostate is fairly common place, and although research is still limited (and much of the evidence for its efficacy is anecdotal) the popularity of this compound continues to grow. Like THC, CBD is a cannabinoid, an active compound found in cannabis. But unlike THC, CBD is non-psychoactive, so it doesn’t get the user high.

Some researchers are examining cannabidiol and other cannabinoids as part of a larger treatment for common prostate issues, including prostate cancer and prostate enlargement. Little is known for certain at this point, but researchers have uncovered some intriguing findings.

Before we delve into the specifics of CBD for enlarged prostate (and other prostate issues), we need to define the conditions. For the purposes of this article, we’re going to address the three most common prostate issues that men face:

  • Benign prostatic hyperplasia (BPH, commonly known as enlarged prostate)
  • Prostatitis (bacterial and non-bacterial)
  • Prostate cancer

Each of these conditions has its own causes, treatments, and implications when it comes to using cannabidiol.

CBD for Enlarged Prostate (Benign Prostatic Hyperplasia)

The term “enlarged prostate” most commonly refers to benign prostatic hyperplasia (BPH). This is a condition where the prostate is enlarged but not affected by cancer. It commonly affects older men and may cause unpleasant symptoms like painful urination, pain in the hips and pelvic area, blood in the urine or semen, painful ejaculation, and frequent urination.

Though prostate enlargement can have numerous causes including inflammation, UTI, and kidney stones, it’s important to understand the role that testosterone plays. Testosterone causes the prostate to grow, so it may be possible to reduce the likelihood of hyperplasia by slowing testosterone production.

Some research indicates that cannabinoids like cannabidiol may inhibit testosterone production. This may prove beneficial for people who struggle with recurrent BPH. Though researchers point to THC as being the cannabinoid most closely associated with this effect, there may still be value in CBD and other cannabinoids as well.

For BPH sufferers, there’s another possible benefit of taking CBD: pain relief. In a comprehensive review of cannabis studies, the National Academies of Sciences, Engineering, and Medicine found that “there is conclusive or substantial evidence that cannabis or cannabinoids are effective for the treatment for chronic pain in adults.” A University of South Carolina School of Medicine study found cannabidiol to be among the most effective cannabinoids for inflammation.

CBD for Prostatitis

Not to be confused with an enlarged prostate, prostatitis is a condition commonly caused by a type of bacteria that enters the prostate from the urinary tract; it can also be caused by a sexually transmitted disease like HIV or chlamydia. The condition may be chronic or acute, and it affects people of all ages.

As with enlarged prostate, cannabidiol may be able to relieve some of the pain, discomfort, and inflammation associated with this condition. What’s more intriguing, cannabidiol may have antibacterial properties that can address the problem at its source. Researchers at the Institute for Molecular Bioscience at the University of Queensland tested the antibacterial properties of CBD and found that it “had a very similar potency to that of common antibiotics.” This is an intriguing development, as antibiotics are the most common treatment solution for prostatitis.

CBD and Prostate Cancer

Prostate cancer is the second-most common cancer that men face (the first being skin cancer), impacting about 175 thousand American men each year. Over the past few years, researchers have been looking at cannabinoids as a potential treatment option for people with prostate cancer. A 2013 study found that cannabidiol is particularly effective among cannabinoids as a killer of prostate cancer cells. A growing body of research reinforces this potential. While cannabidiol may not cure prostate cancer, the compound may be effective for helping prevent and treat the disease.

In addition, CBD may help with the vomiting and nausea associated with chemotherapy. Research shows a link between the body’s endocannabinoid system (the internal receptors that respond to cannabinoids) and the areas of the brain responsible for nausea and vomiting. For those struggling with nausea as part of a cancer treatment, CBD may help to provide some relief.

Should You Take Cannabis or CBD for Prostate Issues?

Granted much of the research has focused on the whole cannabis plant and the full spectrum of cannabinoids, raising the question as to whether CBD on its own has as much value. While cannabidiol should provide at least some of the desired benefit, here are the factors to consider:

  • CBD is non-psychoactive while whole-plant cannabis is psychoactive. If you don’t want the high or you’re concerned that you may be subject to drug-testing, stick with cannabidiol.
  • Cannabis may be more potent overall due to the entourage effect (the interaction of cannabinoids, terpenes, and other compounds to maximize the drug’s effect). However, a Full Spectrum CBD product may also offer the entourage effect to a lesser extent. That’s because it contains all the compounds, including THC—the THC content is limited to just .3% in hemp-derived products.
  • Recreational cannabis is legal in 11 states, and medical marijuana is legal in 33 states with the proper doctor’s recommendation. Hemp-derived CBD products are legal nationwide. If you want to remain in compliance with the law, you may need to consider this as a deciding factor.

If you’re considering CBD for prostate issues, first speak with your licensed cannabis doctor. Then consider if cannabidiol or other cannabinoids might be a viable part of your treatment. CBD has only minor side effects and is well-tolerated in most people, so it’s worth trying out even if the benefits prove to be minor.
