“The endocannabinoid system is implicated in a variety of physiological and pathological conditions (inflammation, immunomodulation, analgesia, cancer and others).

The main active ingredient of cannabis, Δ(9) -tetrahydrocannabinol (Δ(9) -THC), produces its effects through activation of CB(1) and CB(2) receptors. CB(1) receptors are expressed at high levels in the central nervous system (CNS), whereas CB(2) receptors are concentrated predominantly, although not exclusively, in cells of the immune system.

Endocannabinoids are endogenous lipid-signalling molecules that are generated in the cell membrane from phospholipid precursors. The two best characterized endocannabinoids identified to date are anandamide (AEA) and 2-arachidonoylglycerol (2-AG). Here we review the relationship between the endocannabinoid system and anti-tumour actions (inhibition of cell proliferation and migration, induction of apoptosis, reduction of tumour growth) of the cannabinoids in different types of cancer.

This review will focus on examining how activation of the endocannabinoid system impacts breast, prostate and bone cancers in both in vitro and in vivo systems. The therapeutic potential of cannabinoids for cancer, as identified in clinical trials, is also discussed.

Identification of safe and effective treatments to manage and improve cancer therapy is critical to improve quality of life and reduce unnecessary suffering in cancer patients. In this regard, cannabis-like compounds offer therapeutic potential for the treatment of breast, prostate and bone cancer in patients.

Further basic research on anti-cancer properties of cannabinoids as well as clinical trials of cannabinoid therapeutic efficacy in breast, prostate and bone cancer is therefore warranted.” http://www.ncbi.nlm.nih.gov/pubmed/21410463

“The available literature suggests that the endocannabinoid system may be targeted to suppress the evolution and progression of breast, prostate and bone cancer as well as the accompanying pain syndromes. Many in vitro and in vivo studies have shown that cannabinoids are efficacious in reducing cancer progression (i.e. inhibition of tumour growth and metastases as well as induction of apoptosis and other anti-cancer properties) in breast, prostate and bone cancer. Although this review focuses on these three types of cancer, activation of the endocannabinoid signalling system produces anti-cancer effects in other types of cancer.” http://onlinelibrary.wiley.com/doi/10.1111/j.1476-5381.2011.01327.x/full

THC From Cannabis Destroys Cancer Cells

“The study results strongly suggest that if taken regularly, cannabis oil may be able to induce remission in leukemia patients without the horrendous side effects typically associated with standard radio-chemical treatment options. Although this is only one such study, other similar studies have shown equally impressive results.

 Many of the active ingredients found in cannabis-derived drugs show exceptional promise in treating some of the greatest hurdles facing modern medical science. In addition to their aforementioned capacity for safely treating certain forms of deadly cancer, they also show great promise in alleviating autoimmune conditions such as rheumatoid arthritis, multiple sclerosis, and even inflammatory bowel disease. A growing number of experts also note their possible viability treating a range of neurological disorders including Alzheimer’s and Lou Gehrig’s disease.”

NBC News Reports that Cannabidiol (CBD) “Turns Off” the Cancer Gene Involved in Metastasis Findings by Scientists at California Pacific Medical Center gives Scientific Support for Cannabis Science Initiatives

“cannabidiol, (CBD), has the ability to “turn off” a gene that causes breast and other types of cancers to metastasize, according to the San Francisco Chronicle newspaper.

“What they found is that the cannabinoid turns off the overexpression of ID-1, which makes the cells lose their ability to travel to distant tissues. In other words, it keeps the cells more local and blocks their ability to metastasize. (spread to a new location) The researchers stressed cannabidiol works only on cancer cells that have these high levels of ID-1 and these do not include all cancerous tumors but, rather, aggressive, metastatic cells. But they’ve found such high levels in leukemia, colorectal, pancreatic, lung, ovarian, brain and other cancers.””

“The hemp plant Cannabis sativa produces unique compounds known as cannabinoids, of which Δ9-tetrahydrocannabinol (THC) is the most important… The present study was undertaken to investigate the antitumoral action of cannabinoids in pancreatic cancer and the molecular mechanisms involved in that effect… Cannabinoids induce apoptosis of pancreatic tumor cells via endoplasmic reticulum stress-related genes…These findings may contribute to set the basis for a new therapeutic approach for the treatment of pancreatic cancer.”
