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.
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.
Cannabis and prostate cancer
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.
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:
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.
Cannabinoids (CBD) have been widely used in medicines for centuries to control pain, nausea or vomiting, and to stimulate appetite, especially in cancer patients. Both cannabinoids receptor 1(CB1) and cannabinoids receptor 2 (CB2) were highly expressed in cultured prostate cancer cells compared to normal prostate cell lines. CBD inhibits tumor growth in xenograft model.
Clinicians have been challenged to improve the treatment of biochemically recurrent (BCR) prostate cancer in which prostatic specific antigen (PSA) rises without radiological or clinical progression years after localized treatment (radical prostatectomy or radiation therapy) with or without hormonal treatment. Approximately 50-90% of men with high-risk prostate cancer will experience a BCR. Based on the abovementioned preclinical observations of CBD’s effect on prostate cancer and its safety data in two non-cancer populations, a phase I study of CBD in men with biochemically recurrent prostate cancer will be conducted.
Is CBD oil even legal?
Finally, there have been some reports of people getting infections after using CBD and cannabis products. This is especially concerning for immunocompromised patients, who are already susceptible to bacterial and fungal infections.
Quality, cleanliness and regulation are the biggest concerns.
CBD has a very complex legal status right now.
But the application of this law is pretty jumbled right now. So, while it may be legal to use CBD in a state like Colorado or Alaska, if an employer follows federal regulations, the standardization and quality of a CBD product matters. Because if there’s even a small percentage of THC in that product, then a drug test might come back positive. And this could result in legal issues for the user.
It comes in many forms: oils that are dropped under the tongue, roll-ons that are applied to the skin and even solutions for vaping. Some producers extract CBD oil and add it into foods to create edible products.
Is there any truth to the claims that CBD oil can cure cancer?
