The role of cannabinoids in prostate cancer: Basic science perspective and potential clinical applications.

“Prostate cancer is a global public health problem, and it is the most common cancer in American men and the second cause for cancer-related death. Experimental evidence shows that prostate tissue possesses cannabinoid receptors and their stimulation results in anti-androgenic effects.”

“Cannabis is a bushy plant with palmate leaves and clusters of small green flowers, and it grows wild in regions of tropical weather and can attain up to 3 m height. The genus Cannabis is complemented by sativa which translates to useful. Cannabis has indeed been used throughout history for a variety of purposes, including the production of fiber for paper and textile manufacture. However, its current popularity lies in its use as a recreational drug with psychoactive properties. The plant contains many chemical compounds that have different pharmacological properties, varying in quantity and quality depending on the strain, culture, and storage conditions.”

“The frequently held view of cannabis and its related products as drugs of abuse have slowed progress in the development of studies designed to take advantage of the properties of cannabinoid derivatives for therapeutic purposes…”

“Delta-9-THC is the substance with the greatest psychoactive potency of the natural cannabinoids and exhibits the greatest analgesic activity. Cannabidiol (CBD), another major constituent of the Cannabis sativa plant, has the same therapeutic effects of THC (analgesic, anti-inflammatory, and others), but with a different pharmacologic profile…”

“It is our conclusion that it would be of interest to conduct clinical trials involving medicinal cannabis or other cannabinoid agonists, comparing clinical markers such as PSA with controls, especially in men with bone metastatic prostate cancer, whom would not only benefit from the possible anti-androgenic effects of cannabinoids but also from analgesia of bone pain, improving quality of life, while reducing narcotic consumption and preventing opioid dependence.”
