The Data is Very Strong: Marijuana Plant Extract Stops Cancers From Spreadings

The data is very strong and there’s no toxicity associated with A compound found in cannabis could halt the spread of many forms of aggressive cancer, scientists say.

The first research to show marijuana’s anti-tumor properties was presented at the American Association for Cancer Research meeting in Los Angeles in 2007 demonstrating that THC may activate biological pathways that halt cancer cell division or block development of blood vessels that feed tumors. It then became a target of synthetic research into THC for drugs such as ImClone System Inc.’s Erbitux and Amgen Inc.’s Vectibix.

Researchers have now found that the compound, called cannabidiol, had the ability to ‘switch off’ the gene responsible for metastasis in an aggressive form of breast cancer. 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.

Last year they published a study that found a similar effect in mice. Now they say they are on the verge of publishing further animal study results that expand these results further.

Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention. CBD (Cannabidiol), one of the main constituents of the cannabis plant has been proven medically to relieve many diseases including the inhibition of cancer cell growth. Recent studies have shown it to be an effective atypical anti-psychotic in treating schizophrenia. CBD also interferes with the amount of THC your brain processes, balancing the psychotropic effect of marijuana. That is precisely why the power of raw cannabis is turning heads.
Speaking to the San Francisco Chronicle, study co-leader Dr Sean McAllister, said: ‘The preclinical trial data is very strong, and there’s no toxicity. There’s really a lot or research to move ahead with and to get people excited.’

While he, along with colleague Dr Pierre Desprez acknowledge that they are some way off from turning their finding into a pill, they are already developing human trial models. They hope to eventually test the drug in combination with current chemotherapies.

Professor Desprez had previously found that a protein called ID-1 seemed to play a role in causing breast cancer to spread. Meanwhile Dr McAllister had discovered the cannabidiol had anti-cancer potential. The pair teamed up to see if they could treat a particularly aggressive form of breast cancer called ‘triple negative.’ This form, which affects 15 per cent of patients, doesn’t have three hormone receptors that the most successful therapies target. Cells from this cancer have high levels of ID-1.

When they exposed cells from this cancer to cannabidiol they were shocked to find the cells not only stopped acting ‘crazy’ but also returned to a healthy normal state.

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.

Dr Desprez has a particular reason for wanting to create a treatment as quickly as possible – his sister was recently diagnosed with aggressive breast cancer at the age of 41.

Her condition is currently receptive to hormone therapies but Professor Desprez fears it could recur in a form that lacks hormone receptors.

He said: ‘I want to be ready for that. There is a deadline.’

Cannabis is a Class B drug that is illegal to have, give away or sell. “If cannabis were discovered in an Amazon rainforests today, people would be clambering to make as much use as they could out of the potential benefits of the plant,” said Donald L. Abrams, MD, Chief of Hematology and Oncology at San Francisco General Hospital and Professor of Medicine at the University California. Dr. Abrams is widely known for his research on medical cannabis applications. “Unfortunately, it carries with it a long and not so long history of being a persecuted plant,” he added.

Legalize Freedom's picture

IF a person has cancer they need THC, it relieves their pain. 

It is not humane to strip a plant into molecules and then try to craft them into pills, the plant is as it is a complete treatment, and it has given us the option of if we want the high or not, as it being put into a juicer does not convert the THC into a way that we can get high from,


whereas when one does what rick simpson does as i understand it the high is part of the healing because it lets one have relief and relaxation, ease and comfort, appreciation and more. 


This is UNDERSTOOD, its been ON TV, I saw it on tv when I was still in college half a decade ago. THIS IS OLD NEWS, but its also NEW NEWS, 

how do we get the policy changed ? 

QUESTION : does congress want us all to die from cancer ? How can any politician no matter how greedy at least not use t heir greed to figure out a way to legalize it .

No, I don't believe that Congress wants "us to die of cancer". But, I Do believe that Government is being controlled ( as are the rest of us) by BIG industry, such as Big Pharma!
They don't necessarily want us to die, but they don't want to be stripped of their fortunes by not being in control of what we decide to use in our own healing process!
If Cannabis were legalized, it would quite simply, put the pharmaceutical companies out of business in many areas of treatment for diseases.

They might not wish us dead......but they damn sure aren't willing to give up the trillions of dollars they make every year from cancer treatments, even IF it would mean saving thousands of lives!

It is up to all of US, to blast out as much information about the many uses of Cannabis, in order to start a real revolution for legalizing it!

Old news ignored is still news

In '04 I was watching my beloved sister starve to death because of the chemo that was killing her (not the cancer). I was in a different state visiting her for the last time. I was watching her die. She hadn't held down a meal for more than 15 minutes for weeks. Now, she was vomiting up the water she was drinking too and she was not only starving but dehydrating to death. She had been prescribed Marinol which did NOTHING for her appetite. I said, enough. I drove to the local college town, struck up a conversation with some medical students in a bar, knowing no one. After getting to know them for a while I told them the real reason I was there. I needed to find some marijuana. They were able to find me just a little bit. I brought to my sister who smoked just a little bit. She ate and ate and ate and ate and held it down for 6 whole hours. She died a week later but for those 6 hours she enjoyed a short respite from her torment.

When I think of the suffering the cancer industry has caused and the financial devastation they cause, it makes me want to vomit. This plant is a blessing to humanity and should be treated as such. Those who want to smoke it for recreational purposes, fine, as far as I am concerned. It is a victimless crime. The criminalization of this plant has left 60,000 people dead in the Mexican drug war. Our politicians have their heads up their asses along with the AMA and the Pharmaceutical mafia. Meanwhile our prisons are filling with a new underclass of people incarcerated for the victimless crime of wanting to get high, and millions of cancer patients are murdered by the cancer industry while being denied a real cure that these power brokers have known about for years. WHO do they think they are?

The fda will not pass this as it cures people...simple as that...the system is so corrupt but I think the tide is turning and people are waking up to what is going on. Hemp (canabis) was grown on millions of acres of american soul as old black and white utube films show but then it was banned in early 40's and made illegal. It was banned because it was found to cure cancer. Hemp is the most versitile crop ever with many uses

No profit or patent can be

No profit or patent can be made from a natural compound that has been available for thousands of years. So the industry concocts an expensive manmade conncoction of toxic poison as a 'cure'.

The natural oil/tincture can be obtained online
