“A compound found in cannabis could halt the spread of many forms of aggressive cancer, scientists have claimed.

Researchers found that the compound, called cannabidiol, had the ability to “switch off” the gene responsible for metastasis in an aggressive form of breast cancer, the Daily Mail reported.

Importantly, this substance does not produce the psychoactive properties of the cannabis plant.

The team from the California Pacific Medical Center, in San Francisco, first spotted its potential five years ago, after it stopped the proliferation of human breast cancer cells in the lab, the report said.

They discovered that the compound had turned off the overexpression of ID-1, stopping them from travelling to distant tissues.

Other potentially treatable cancers are forms of leukaemia, lung, ovarian and brain cancers, which also have high levels of ID-1.”

“Cannabinoids are a class of pharmacologic compounds that offer potential applications as antitumor drugs, based on the ability of some members of this class to limit inflammation, cell proliferation, and cell survival. In particular, emerging evidence suggests that agonists of cannabinoid receptors expressed by tumor cells may offer a novel strategy to treat cancer. Here, we review recent work that raises interest in the development and exploration of potent, nontoxic, and nonhabit forming cannabinoids for cancer therapy.

 there is overwhelming evidence to suggest that cannabinoids can be explored as chemotherapeutic agents for the treatment of cancer.”

“The endocannabinoid system comprises the cannabinoid receptors type 1 (CB1) and type 2 (CB2), their endogenous ligands (endocannabinoids), and the proteins responsible for their biosynthesis and degradation. This ubiquitous signalling system, that has attracted a great deal of scientist interest in the past 15 years, regulates several physiological and pathological functions. In mammals, among other functions, the endocannabinoid is involved in nervous, cardiovascular, metabolic, reproductive and immune functions. Finally, yet importantly, endocannabinoids are known to exert important antiproliferative actions in a great number of tumor cells including breast, brain, skin, thyroid, prostate and colorectal. The following review describes our current knowledge on the effects of two of the most studied endocannabinoids (AEA and 2-AG) on various types of tumor and summarizes the possible mechanism of observed antitumor effects.”  http://www.ncbi.nlm.nih.gov/pubmed/21428888

“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

No medical benefit from marijuana? How about a cancer cure?

“It’s been known for a long time that THC and other cannabinoids can effectively treat symptoms of cancer sufferers and chemotherapy patients, such as nausea, pain, loss of appetite and fatigue. But what scientists have proven in laboratory experiments and testing on animals the last few years is that cannabinoids also can kill cancer cells and stop the spread of aggressive types of the disease — cancer of the breast, brain, prostate, colon or lungs.

The way cannabinoids work, simply put, is by blocking or deactivating a gene called ID-1 that spreads cancer. One compound that’s been found to be especially effective doing this is called cannabidiol, or CBD.

Also, CBD (which unlike THC is non-psychoactive) and other cannabinoids are non-toxic, which greatly reduces the risk of harmful effects from their use.”

“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.”

Cannabis Oil Fights Cancer

“Oil extracted from the marijuana plant has been shown to have extraordinary cancer-fighting properties.

A number of recent studies have confirmed the cancer-fighting, tumor-shrinking value of medical marijuana.

Although the first study to demonstrate that cannabis has anti-carcinogenic properties was done  back in 1974 by the U.S. National Institute of Health, more recent studies, which began abroad in 1999, have shown that cannabis can effectively and safely treat many forms of cancer.

Since 1999, there have now been a number of studies that clearly demonstrate that cannabis has the ability to effectively shrink tumors, kill cancer cells, and safely treat many aggressive forms of cancer, including brain, breast, skin, prostate, and lung cancer.

However, due to the political controversy that surrounds medical marijuana, some physicians still remain unaware of these valuable studies, and mistakenly believe the misguided government reports that cannabis actually causes cancer. In some cases, it may be important to educate your doctor about the important research discussed in this column.”

Marijuana May Fight Lung Tumors – CBSNews

“the active ingredient in marijuana may help combat lung cancer, new research suggests.

Moreover, other early research suggests the cannabis compound could help fight brain, prostate, and skin cancers as well, Preet says.

The finding builds on the recent discovery of the body’s own cannabinoid system, Preet says. Known as endocannabinoids, the natural cannabinoids stimulate appetite and control pain and inflammation.

THC seeks out, attaches to, and activates two specific endocannabinoids that are present in high amounts on lung cancer cells, Preet says. This revs up their natural anti-inflammatory properties. Inflammation can promote the growth and spread of cancer.

In the new study, the researchers first demonstrated that THC inhibited the growth and spread of cells from two different lung cancer cell lines and from patient lung tumors. Then, they injected THC into mice that had been implanted with human lung cancer cells. After three weeks, tumors shrank by about 50 percent, compared with tumors in untreated mice.”

“The article states that scientists at California Pacific Medical Center who have been researching marijuana’s compounds for the 20 years have found that Cannabidiol, or CBD, has the ability to “turn off” the DNA that causes “breast and other types of cancers” to metastasize. CBD is the second-most abundant cannabinoid within marijuana, but does not cause the psychotropic high of THC.

As stated in the article: “We started by researching breast cancer,” said scientist Pierre Desprez. “But now we’ve found that Cannabidiol works with many kinds of aggressive cancers–brain, prostate–any kind in which these high levels of ID-1 are present.””

“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.””
