Update on Cannabis and Prostate Cancer

Research since the March 2018 posting of the blog below supports the anti-tumor effect of non-psychoactive CBD (cannabidiol), one of 100+ identified plant-derived cannabinoid compounds. For example, Kis et al. note that lab studies have shown a chemopreventive effect of cannabidiol in prostate cancer (PCa) as well as stimulating PCa cancer cell death pathways and boosting genomic antitumor activity. [i] Furthermore, CBD is a “potent inhibitor” of the release of exosomes from PCa cells; exosomes are very tiny particles containing molecular messages that can change the behavior of healthy cells that receive them, and are thus a biogenetic pathway for the spread of PCa. A cell study by Kosgodade et al. revealed that CBD’s ability to regulate the release of PCa exosomes is one of its mechanisms for anti-cancer activity, though such dose-dependent activity appears more powerful in some types of cells others. [ii]

Thus, there is clear evidence that CBD has properties that inhibit PCa cell growth and division, encouraging cancer cell death, and block cancer cells from transforming normal cells into PCa. However, all research thus far has been conducted either in lab animals or using lab-cultured PCa cell lines. The only human clinical trials of CBD are with advanced PCa patients for management of pain and chemotherapy side effects. Thus, the potential use of CBD as a PCa prevention or a treatment for localized PCa is promising but remains hypothetical.

Cannabis (marijuana, pot, weed, grass etc.) is a widely used recreational and medicinal drug. In fact, cannabis use dates far back in ancient times, probably for the same two purposes. Today, state laws in the U.S. are rapidly becoming more permissive less than a century after it was made illegal in 1937.

According to Ramos & Bianco (1912), “The plant contains many chemical compounds that have different pharmacological properties, varying in quantity and quality depending on the strain, culture, and storage conditions. In 1964, Mechoulam and colleagues found that delta-9-tetrahydrocannabinol (THC) was the major psychoactive ingredient of cannabis.”[iii] These compounds, including THC, are called cannabinoids, and 66 separate cannabinoids have been identified.

Cannabinoids produce their physical and psychological effects by interacting with specific receptors on cell surfaces that have an affinity for these compounds. There are two types of receptors:

  • Cannabinoid receptor type 1 (CB1) are mostly found in the brain, and also in the male and female reproductive systems. To a lesser extent, they exist in central and peripheral pain pathways (nerves) which may explain why pain relief is a benefit of cannabinoids, particularly THC.
  • Cannabinoid receptor type 2 (CB2) are primarily found in the immune system, and may be associated with anti-inflammatory and other therapeutic effects of cannabis.

Cannabis and prostate cancer

There has been both enthusiasm and caution about cannabis use and cancer. By mid-2015, 23 states had legalized medical marijuana, one of the primary uses being to ease the side effects of chemotherapy and radiation in cancer treatment. As described above, CB1 receptors play a key role in cancer pain relief.

Now, as scientific research into the two types of cannabinoid receptors has progressed, understanding how cannabinoids interact with prostate cancer cells opens the possibility of using these compounds to restrict the activity, including the growth and spread, of prostate cancer itself.

How cannabis affects prostate cancer cells

Research shows that prostate cancer cells have higher levels of expression of both CB1 and CB2 receptors than normal cells. To put it another way, the cancer cells have a greater affinity for cannabinoids than normal cells. Laboratory studies[iv] have demonstrated that when the cells are treated with a specific cannabinoids, three consequences occur:

  1. In general, the cells became less viable and more prone to apoptosis (programmed cell death), and
  2. Androgen receptor activity on the cancer cell surfaces decreased (prostate cancer appears to be “fueled” by androgens, or male hormones)
  3. Two cannabinoids, THC and CBD, discourage the formation of tumor blood vessels (angiogenesis) needed by prostate cancer tumors to nourish themselves.[v]

A very extensive study was conducted by De Petrocellis et al. (2012)[vi] using both prostate cancer cells in lab containers and prostate cancer tumor cells implanted in mice. Non-THC cannabinoids were thus tested for their biochemical effects on individual cells as well as actual tumor behavior in live animals. The overall results were encouraging, with the authors suggesting that “non-THC cannabinoids, and CBD in particular, retard proliferation and cause apoptosis of PCC [prostate cancer cells] via a combination of cannabinoid receptor-independent, cellular and molecular mechanisms.”

The current state of cannabinoids and prostate cancer

With such promising research evidence that cannabinoids are destructive to prostate cancer cells, what is happening with actual prostate cancer patients? Not much, according to a prostate.net blog:

There are many stories of people who have used cannabis oil to shrink prostate cancer tumors, and many of the people had success combining the oil with traditional therapies to fight their cancer. The problem with getting hard data and studies is that United States laws make it challenging for clinical studies on the marijuana plant to take place. Plus, there seems to be a lack of funding for the research. The studies that have taken place tend to focus on symptoms (such as pain relief and nausea) rather than the efficacy of the cannabis oil to shrink cancer tumors.

Yet the research teams who have published their results with laboratory experiments, both in lab containers and animal studies, are clearly calling for clinical trials with patients. They point out that non-THC cannabinoids demonstrate properties that keep the cells from proliferating, spreading, building their own blood supply, and taking up androgens (male hormones). In addition, the De Petrocellis study found that under certain conditions, cannabinoids had a synergistic effect with chemotherapy (docetaxel) or hormone therapy (bicalutamide). Such features conjure visions of creative directions in prostate cancer treatment.

Ramos & Bianco explicitly describe a constructive scenario for prostate cancer patients with painful metastasis to the bone. As they state, cannabinoids “harbor analgesic properties that aid bone cancer pain, reduce opioid consumption, side effects, and dependence, as well as exhibiting anti-androgenic effects on experimental prostate cancer cells.”

Perhaps today’s trend of relaxing cannabis restrictions will open the path to human clinical trials, and the real value of cannabinoids in the treatment of prostate cancer will be revealed.

Can CBD Oil Treat Prostate Cancer?

Studies conducted particularly on prostate cancer that is grown in laboratories or used in research on mice revealed that Cannabinoids have a great potential to stop prostate cancer cells from growing and dividing.

The findings generally state that CBD can cause prostate cancer cells to die and prevent such cancer cells from spreading and invading other tissues.

However, take note that these findings on CBD fighting prostate cancer symptoms come from research on mice. Therefore, it is inconclusive as CBD oil, in this case, is not tested on humans yet, thus researchers are unsure if Cannabinoids have similar effects in human patients with prostate cancer.

Needless to say, much remains to be done in determining whether CBD oil is effective in the treatment of prostate cancer signs in humans. Apparently because human cells can behave differently than animals tested in laboratories. So, heaps of clinical trials are needed to see if CBD oil side effects are good for prostate cancer treatment.

However, the lack of evidence that Cannabidiol oil can treat prostate cancer symptoms does not mean that CBD oil is irrelevant for people with prostate cancer – hundreds of cancer patients around the world are convinced that the use of CBD oil has been a massive help in fighting cancer and, ultimately, in improving their health.

What is CBD Oil?

Cannabidiol or CBD oil can be extracted from the Cannabis Sativa, a plant that has practical medicinal use for thousands of years – the plant comes in many types but the most common sources of Cannabinoids in CBD oils are marijuana and hemp.

Cannabinoids in CBD oil are just one of the many chemical components of Cannabis Sativa. Its other chemical component is the THC (tetrahydrocannabinol), which is the psychoactive chemical component that is often responsible for producing the euphoric high, causing people to hallucinate.

However, most CBD oils that are generally and legally accepted in Ireland and around the world come from cold-pressing the Hemp plant – this is because Cannabidiol oil extracted from the cold-pressed Hemp plant only contains about 0.3% of Tetrahydrocannabinol (THC) which is a harmless amount.

So, unlike other types of cannabis oil, CBD oil extracted from the Hemp plant contains a non-psychoactive component and does not cause hallucinations and other harmful effects.

How Does Cannabidiol or CBD Oil Treat Prostate Cancer?

Studies have shown that CBD oil is a natural treatment that does not seem to cause harm to other cells in the body. Plus, cancer patients claim that their intake of Cannabidiol oil is better tolerated by their body than chemotherapy.

It has been found that prostate tissues have cannabinoid receptors. So, men taking CBD oil stimulates these receptors and this results in anti-androgenic effects – antiandrogens are commonly used in the treatment of prostate cancer signs.

Still, more studies, especially on patients using CBD oil for prostate cancer symptoms, are needed to validate these claims, although there is plenty of anecdotal evidence of cannabis oil shrinking prostate cancer tumors while reducing pain, eliminating insomnia, and helping the patients have a general sense of well-being.

Stories abound about patients who have used cannabis oil to shrink prostate cancer tumors and others who were able to combine the use of different types of CBD oil with traditional treatment to fight cancer.

Hopefully, these stories from aiming for prostate cancer treatment will push medical professionals to conduct more research about the effectiveness of CBD oil in helping cure prostate cancer signs and ultimately push for the legal use of CBD oil Ireland-wide.

CBD Oil Helps with Three Major Types of Prostate Ailments

Researchers have been examining CBD oil and other cannabinoids as a treatment for most prostate issues such as prostatitis and prostate enlargement. At present, there is still much to be learned, and researchers have discovered some interesting findings.

Three of the most common prostate issues that men are experiencing:

Prostate Cancer

In a 2013 study, researchers have found that cannabidiol is particularly effective among cannabinoids as a killer of prostate cancer cells. Many other studies and research have supported this potential.

While CBD oil may not have much evidence in prostate cancer treatment, it is undeniable that the oil itself has the potential effectiveness in helping prevent and treat the disease.


Prostatitis is a condition caused by a type of bacteria that enters the prostate from the urinary tract. It can also be caused by sexually transmitted diseases like HIV or chlamydia. It can be chronic or acute and affects people of all ages.

In this case, CBD oil may be able to relieve some of the pain, discomfort, and inflammation associated with this condition. Another interesting aspect of CBD oil is that it may have antibacterial properties that can treat prostatitis at its source.

Scientists at the Institute for Molecular Bioscience at the University of Queensland tested the antibacterial properties of CBD oil and found that it has a very similar potency to common antibiotics.

Enlarged Prostate (Benign Prostatic Hyperplasia)

Enlarged prostate refers to benign prostatic hyperplasia (BPH). In this case, the prostate is enlarged but not affected by cancer. The condition commonly affects older men and may cause unpleasant symptoms such as painful urination, pain in the hips and pelvic area, blood in the urine or semen, painful ejaculation, and frequent urination.

Prostate enlargement has several causes such as inflammation, UTI, and kidney stones, but testosterone is one of the likely reasons. Testosterone causes the prostate to grow, and thus slowing testosterone production may reduce the possibility of having hyperplasia.

Studies have shown that CBD oil may inhibit testosterone production, and this can be good news for those with recurring BPH. Although researchers have found THC as the cannabinoid most responsible for this, Cannabidiol oil may well be effective as well in the reduction of testosterone.

Another benefit of taking CBD oil as a treatment for BPH is pain relief. A comprehensive review of cannabis studies by the National Academies of Sciences, Engineering, and Medicine found that there is enough evidence that cannabis and cannabidiol are effective for the treatment of chronic pain in adults.

Also, a study conducted by the University of South Carolina School of Medicine found that CBD oil to be among the most effective cannabinoids for inflammation.
