“ACTIVE chemicals in cannabis have been shown to halt prostate cancer cell growth according to research published in the British Journal of Cancer.
Researchers from the University of Alcala, in Madrid tested the effects of the active chemicals in cannabis called cannabinoids on three human prostate cancer cell lines – called PC-3, DU-a45 and LNCaP.
The prostate cancer cells carry molecular ‘garages’- called receptors- in which cannabinoids can ‘park’.
The scientists showed for the first time that if cannabinoids ‘park’ on a receptor called CB2, the cancer cells stop multipyling.
Dr Walker added: “This research suggest that prostate cancer cells might stop growing if they are treated with chemicals found in cannabis but more work needs to be done to explore the potential of the cannabinoids in treatment.”
To confirm the findings the scientists switched off the CB2 receptors – or ‘closed the garage doors’- on the prostate cells. When cannabinoids were then added to cells without the CB2 receptor, the prostate cancer cells carried on dividing and growing. This suggests that cannabinoids connect with the CB2 receptors on prostate cancer cells to stop cell division and spread.
Professor Ines Diaz-Laviada, study author at the University of Alcala said: “Our research shows that there are areas on prostate cancer cells which can recognise and talk to chemicals found in cannabis called cannabinoids. These chemicals can stop the division and growth of prostate cancer cells and could become a target for new research into potential drugs to treat prostate cancer.”

“Anyone who has ever known and loved someone using chemotherapy knows just what a toxic cocktail those drugs truly are. So when faced with the idea that an 8-month-old baby could go through those horrific side effects or try something else, namely marijuana, to treat a brain tumor, my money is on the “something else” every time.”
“This is exactly the question parents of an 8-month-old baby were faced with recently when they opted to treat their baby with cannabinoid oil (a form of marijuana) on the baby’s pacifier twice a day. Within two months the tumor had shrunk so dramatically that the baby’s doctor’s did not have to use chemo. Amazing, no?”
“The long term effects of marijuana on a baby are probably unknown, but the long term effects of chemotherapy may be just as harmful, if not even worse. At least cannabis can be grown safely and organically and given in as natural a state as possible.”
“Ordinarily I would frown on parents giving any kind of substance to a baby, but a baby with a brain tumor is another kind of story. In this case, the cannabis helped. Maybe this is the beginning of less invasive treatment methods with fewer side effects. Wouldn’t that be a miracle for ALL children?”
“Would you give your baby cannabinoid oil?”
“Madrid, Spain: THC administration decreases recurrent glioblastoma multiforme (GBM) tumor growth in humans, according to the findings of the first-ever clinical trial assessing cannabinoids’ anti-tumor action.
Investigators at Complutense University in Spain administered THC intratumorally in nine patients diagnosed with recurrent GBM, an extremely rapid and lethal form of brain tumor. Patients in the study had previously failed standard therapy (surgery and radiotherapy) and had clear evidence of tumor progression. THC treatment was associated with reduced tumor cell proliferation in two subjects, authors reported.
Investigators did not determine whether THC positively impacted patients’ survival, though they did conclude that cannabinoid therapy does not facilitate cancer growth or decrease patients’ life expectancy. Median survival of the cohort from the beginning of cannabinoid administration was 24 weeks, and two patients survived for approximately one year. Survival for GBM patients following diagnosis is typically six to twelve months.
Researchers speculated that newly diagnosed glioma patients may respond more favorably to cannabinoid-based therapies.
Investigators also reported that THC demonstrated significant anti-proliferative activity on human GBM cells in culture.
“The fair safety profile of THC, together with its possible anti-proliferative action on tumor cells reported here and in other studies, may set the basis for future trials aimed at evaluating the potential antitumoral activity of cannabinoids,” investigators concluded.
In 2005, investigators at the California Pacific Medical Center Research Institute in San Francisco reported that THC selectively decreases the proliferation of malignant cells and induces cell death in human GBM cell lines. Healthy cells in the study were unaffected by THC administration.
Separate preclinical studies indicate that cannabinoids and endocannabinoids can stave off tumor progression and trigger cell death in other cancer cell lines, including breast carcinoma, prostate carcinoma, colectoral carcinoma, skin carcinoma, and pancreatic adenocarcinoma.”

““Cannabinoids possess … anticancer activity [and may] possibly represent a new class of anti-cancer drugs that retard cancer growth, inhibit angiogenesis (the formation of new blood vessels) and the metastatic spreading of cancer cells.” So concludes a comprehensive review published in the October 2005 issue of the scientific journal Mini-Reviews in Medicinal Chemistry.
Not familiar with the emerging body of research touting cannabis’ ability to stave the spread of certain types of cancers? You’re not alone.
For over 30 years, US politicians and bureaucrats have systematically turned a blind eye to scientific research indicating that marijuana may play a role in cancer prevention — a finding that was first documented in 1974. That year, a research team at the Medical College of Virginia (acting at the behest of the federal government) discovered that cannabis inhibited malignant tumor cell growth in culture and in mice. According to the study’s results, reported nationally in an Aug. 18, 1974, Washington Post newspaper feature, administration of marijuana’s primary cannabinoid THC, “slowed the growth of lung cancers, breast cancers and a virus-induced leukemia in laboratory mice, and prolonged their lives by as much as 36 percent.”
Despite these favorable preclinical findings, US government officials dismissed the study (which was eventually published in the Journal of the National Cancer Institute in 1975), and refused to fund any follow-up research until conducting a similar — though secret — clinical trial in the mid-1990s. That study, conducted by the US National Toxicology Program to the tune of $2 million concluded that mice and rats administered high doses of THC over long periods experienced greater protection against malignant tumors than untreated controls.
Rather than publicize their findings, government researchers once again shelved the results, which only came to light after a draft copy of its findings were leaked in 1997 to a medical journal, which in turn forwarded the story to the national media.
Nevertheless, in the decade since the completion of the National Toxicology trial, the U.S. government has yet to encourage or fund additional, follow up studies examining the cannabinoids’ potential to protect against the spread cancerous tumors.
Fortunately, scientists overseas have generously picked up where US researchers so abruptly left off. In 1998, a research team at Madrid’s Complutense University discovered that THC can selectively induce apoptosis (program cell death) in brain tumor cells without negatively impacting the surrounding healthy cells. Then in 2000, they reported in the journal Nature Medicine that injections of synthetic THC eradicated malignant gliomas (brain tumors) in one-third of treated rats, and prolonged life in another third by six weeks.
In 2003, researchers at the University of Milan in Naples, Italy, reported that non-psychoactive compounds in marijuana inhibited the growth of glioma cells in a dose dependent manner and selectively targeted and killed malignant cancer cells.
The following year, researchers reported in the journal of the American Association for Cancer Research that marijuana’s constituents inhibited the spread of brain cancer in human tumor biopsies. In a related development, a research team from the University of South Florida further noted that THC can also selectively inhibit the activation and replication of gamma herpes viruses. The viruses, which can lie dormant for years within white blood cells before becoming active and spreading to other cells, are thought to increase one’s chances of developing cancers such as Karposis Sarcoma, Burkitts lymphoma, and Hodgkins disease.
More recently, investigators published pre-clinical findings demonstrating that cannabinoids may play a role in inhibiting cell growth of colectoral cancer, skin carcinoma, breast cancer, and prostate cancer, among other conditions. When investigators compared the efficacy of natural cannabinoids to that of a synthetic agonist, THC proved far more beneficial – selectively decreasing the proliferation of malignant cells and inducing apoptosis more rapidly than its synthetic alternative while simultaneously leaving healthy cells unscathed.
Nevertheless, US politicians have been little swayed by these results, and remain steadfastly opposed to the notion of sponsoring – or even acknowledging – this growing body clinical research, preferring instead to promote the unfounded notion that cannabis use causes cancer. Until this bias changes, expect the bulk of research investigating the use of cannabinoids as anticancer agents to remain overseas and, regrettably, overlooked in the public discourse.”

“Medical marijuana is gaining acceptance, but could it even help kids? Dr. William Courtney has seen it happen, and on Friday, told HuffPost Live host Alyona Minkovski about it. Saying he was “quite a skeptic 5 or 6 years ago”, Dr. Courtney continued that “my youngest patient is 8 months old, and had a very massive centrally located inoperable brain tumor.” The child’s father pushed for non-traditional treatment utilizing cannabis.
“They were putting cannabinoid oil on the baby’s pacifier twice a day, increasing the dose… And within two months there was a dramatic reduction, enough that the pediatric oncologist allowed them to go ahead with not pursuing traditional therapy.”
The tumor was remarkably reduced after eight months of treatment. Dr. Courtney pointed out that the success of the cannabis approach means that “this child, because of that, is not going to have the long-term side effects that would come from a very high dose of chemotherapy or radiation… currently the child’s being called a miracle baby, and I would have to agree that this is the perfect response that we should be insisting is frontline therapy for all children before they launch off on all medications that have horrific long term side effects.””

“When 7-year-old Mykayla Comstock was diagnosed with leukemia in July, it was less than three days before her mother filed Oregon medical marijuana paperwork so the child could take lime-flavored capsules filled with cannabis oil.
The decision to give Mykayla the capsules came naturally to Erin Purchase, MyKayla’s mother, who believes marijuana has healing power, but doctors aren’t so sure it’s a good idea.
“The first doctor was not for it at all,” Purchase told ABCNews.com. “She was rude and she told us it was inappropriate. “Basically she blew up at us and told us to transfer to another facility.”
They found a new doctor, who knows that Mykayla takes about a gram of cannabis oil a day — half in the morning and half at night — but he doesn’t talk about it with them.
“This is our daughter,” Purchase, 25, said. “If they don’t agree with our personal choices, we’d rather they not say anything at all.””
.””At first, Mykayla wasn’t responding well to her treatment, and doctors said she might need a bone marrow transplant. Then she started taking the cannabis oil pills. her mother said. By early August, Mykayla was in remission and the transplant was no longer necessary.”
“I don’t think it’s just a coincidence,” Purchase said. “I credit it with helping — at least helping — her ridding the cancer from her body.””

“Like some cancer patients in states where it’s allowed, Mykayla Comstock uses cannabis as part of her treatment. Comstock is 7-years old. Her mother, a long time advocate for medical use of the illegal drug, has been giving her a gram of oral cannabis oil every day. Despite the fact that medical marijuana is legal in Oregon, where Comstock lives, the idea of giving it to a child still gives pause to many adults who associate the drug with recreational use that breaks the law.
As reported by ABC News, Mykayla was diagnosed with acute lymphoblastic leukemia in July. Against her doctor’s wishes, her mother, Erin Purchase, began giving her lime-flavored capsules filled with cannabis oil after she had a poor response to her initial chemotherapy treatment.
Her doctors suggested a bone marrow transplant, but while she was taking the medical marijuana, she went into remission in August. She continues to rely on cannabis to ease pain and nausea and her mother plans to continue giving her the drug during the additional two to three years of chemotherapy she still faces.
Purchase believes that certain components in marijuana, which show anti-cancer activity in many early studies, helped spark the remission. Mykayla’s current doctor knows she takes the capsules, but doesn’t discuss the marijuana as part of her medical therapy.” http://www.cnn.com/2012/11/30/health/medical-marijuana-children-time/
“In an international collaboration of research centers from America and Europe, scientists have revealed that increasing chemicals in the brain that act similarly to marijuana can help repair the debilitating symptoms associated with fragile X syndrome.
The overall success of this study could lead to future treatments for the condition, which has been identified as the most common genetic basis for autism spectrum disorders. The research was published in Nature Communications.
The marijuana-like compound, called 2-AG, is a part of a class of chemicals called endocannabinoid transmitters. These compounds are naturally made by the brain, and they act by combining to receptor proteins in the brain that marijuana chemicals also bind with.
Fragile X syndrome is the result of a mutation of the FMR1 gene in the X chromosome passed on by the mother. The condition occurs mostly in males because females typically have another X chromosome to compensate for the faulty X chromosome. Symptoms of fragile X often include mental disability, walking and language delays and hyperactivity – as well as certain physical characteristics such as an elongated face and large ears.”
“Increasing levels of a marijuana-like compound in the brain may help reduce some behavioral problems seen in people with Fragile X Syndrome.
Researchers say that the marijuana-like compound may help reduce some of the anxiety and learning-related issues in people with this condition. The compound, called 2-AG, falls under a class of chemicals in the brain called endocannabinoids transmitters.
Fragile X syndrome is a genetic disorder that causes learning disabilities. Children with this condition have characteristic physical features like long and narrow face, large forehead and ears, flexible fingers and flat feet that become more apparent as the child ages. The condition is caused by a change in the FMR1 gene that codes for a protein that helps the brain grow properly.”
“YES, finally its time… i have autistic spectrum and i have incorrect behaviors that cannot be fixed unless you tell yourself 24/7 and behaviors and thought process that is incorrect that you will never even know is incorrect. Ive tried marijuana before and the first time ive tried it ive done some self explaining to myself that was very different and i didnt know why. after using marijuana several times which i find relaxing if not used too much at once, i started realizing the difference in thought process and realizing the off things that i do and it got to the point where i actually started figuring out my problems with cannabis and i cant believe the correction in thought process when using this significant plant. there was never a cure for autism but this is the CLOSEST to it. i have a lot more things to say about this but it would take too long to write but all i have to say is this is THE best medication for personality disorders and autistic behaviors and correction to the thought process of such.”
“American and European researchers have found that increasing natural marijuana-like chemicals in the brain may help correct behavioral issues related to autism.
Daniele Piomelli of UC Irvine and Olivier Manzoni of INSERM, the French national research agency, led the study, which could result in treatments of anxiety and cognitive defects in individuals with fragile X syndrome, the most common known genetic cause of autism, according to a press release by UC Irvine.
The study examined 2-AG, which naturally occurs in the brain and is in a class of chemicals called endocannabinoid transmitters. These transmitters allow for the efficient transport of electrical signals at synapses, which is severely limited in people with fragile X syndrome.
The researchers treated mice that exhibited symptoms of fragile X syndrome with novel compounds that correct 2-AG protein signaling in the brain. And the results were promising–the mice showed “dramatic behavioral improvements in maze tests measuring anxiety and open-space acceptance,” UCI reports.
Piomelli said this is the first study to identify the role of naturally-occuring endocannabinoids, which share a similar chemical structure with THC, the primary psychoactive component of marijuana. “What we hope is to one day increase the ability of people with fragile X syndrome to socialize and engage in normal cognitive functions,” said Piomelli, a UCI professor of anatomy and neurobiology.
“It would be either an oral or injected drug but that’s at the very end stage of drug discovery, and we are at the very early stage of drug discovery,” Kwang Mook Jung, a researcher on the study and UCI professor, told The Huffington Post.
In addition, his study of endocannabinoids could result in new treatments for anxiety, pain, depression and obesity, according to UCI.”
