“…the non-psychoactive cannabinoid compound cannabidiol (CBD) effectively limits human glioma cell growth, both in vitro and in vivo… the present investigation confirms the antiproliferative and antiinvasive effects of CBD in U87-MG cells.

 More interestingly, these effects can also be extended to T98G glioma cells, a well known Δ9-THC-resistant lineage…

Taken together, these results provide new insights into the antitumor action of CBD, showing that this cannabinoid affects multiple tumoral features and molecular pathways.

 As CBD is a non-psychoactive phytocannabinoid that appears to be devoid of side effects, our results support its exploitation as an effective anti-cancer drug in the management of gliomas.”

Study: Marijuana Compound Can Kill Some Cancer Cells – TIME

Marijuana leaf

“Compounds derived from marijuana can kill cancerous cells in patients with leukemia, according to a recent study.

The study, published in the Anticancer Research journal, was partially funded by GW Pharmaceuticals. which already produces a cannabis-derived drug to help people with multiple sclerosis. Dr. Wai Liu studied six different non-psychoactive cannabinoids (compounds derived from marijuana that don’t get the user high like its THC component does). He found that certain non-psychoactive cannabinoids “resulted in dramatic reductions in cell viability” and “caused a simultaneous arrest at all phases of the cell cycle,” according to the study summary posted online.

Leukemia will take the lives of an estimated 23,720 people this year.

This isn’t the first time marijuana has been linked to deterring cancer: In 2012, researchers at the California Pacific Medical Center in San Francisco found that CBD — a non-psychoactive chemical compound found in cannabis — can stop metastasis in some kinds of aggressive cancer. Liu told the Huffington Post that smoking cannabis is unlikely to have the same cancer-inhibiting effect.”

New Study: Cannabis May Help Cure Cancer

“A recent study shows that cannabis, at least its non-hallucinogenic elements, could serve as a valuable ally in not only treating cancer patients suffering from a myriad of debilitating symptoms, but it could also cure them of the deadly disease.

According to researchers at St. George Hospital Medical School, a subsidiary of the University of London, there is significant evidence that suggests certain cannabinoids found in marijuana could be used as a highly effective anti-cancer drug without patients being forced to experience the psychotropic effects of its use.

“This study is a critical step in unpicking the mysteries of cannabis as a source of medicine,” said Dr. Wai Liu, lead author of this research. “The cannabinoids examined have minimal, if any, hallucinogenic side effects, and their properties as anti-cancer agents are promising. These agents are able to interfere with the development of cancerous cells, stopping them in their tracks and preventing them from growing. In some cases, by using specific dosage patterns, they can destroy cancer cells on their own.””

“Targeting the endocannabinoid system with cannabinoid receptor agonists: pharmacological strategies and therapeutic possibilities. Human tissues express cannabinoid CB(1) and CB(2) receptors that can be activated by endogenously released ‘endocannabinoids’ or exogenously administered compounds in a manner that reduces the symptoms or opposes the underlying causes of several disorders in need of effective therapy. Three medicines that activate cannabinoid CB(1)/CB(2) receptors are now in the clinic: Cesamet (nabilone), Marinol (dronabinol; Δ(9)-tetrahydrocannabinol (Δ(9)-THC)) and Sativex (Δ(9)-THC with cannabidiol)… several possible additional therapeutic targets for cannabinoid receptor agonists. These include other kinds of pain, epilepsy, anxiety, depression, Parkinson’s and Huntington’s diseases, amyotrophic lateral sclerosis, stroke, CANCER, drug dependence, glaucoma, autoimmune uveitis, osteoporosis, sepsis, and hepatic, renal, intestinal and cardiovascular disorders.”

Study: Cannabis Compounds Can Kill Cancer Cells – US News & World Report

“Researcher says cannabinoids might treat cancer as well as billion-dollar drugs.”

A medical marijuana activist holds a sign during a rally Jan. 4, 2010, in Oakland, Calif. Research suggests marijuana may fight cancer itself, not just side-effects.“A British researcher has found that cannabinoids, a term for chemicals derived from marijuana, can kill leukemia cells, and he expects clinical trials for new medications to begin soon.

The findings, published in the October issue of Anticancer Research: International Journal of Cancer Research and Treatment, show that certain non-psychoactive cannabinoids “resulted in dramatic reductions in cell viability” and “caused a simultaneous arrest at all phases of the cell cycle,” according to an abstract posted online. 

The study tested six cannabinoids, together and independently, on leukemia cells. Study author Wai Liu, an oncologist at the University of London’s St. George’s medical school, told U.S. News the chemicals displayed “potent anti-cancer activity” and, significantly, “target and switch off” pathways that allow cancers to grow.”

Systematic review of the literature on clinical and experimental trials on the antitumor effects of cannabinoids in gliomas.

“To evaluate, through a systematic review of the literature, the antitumoral effects of cannabinoids on gliomas…

  In all experimental studies included, cannabinoids exerted antitumoral activity in vitro and/or antitumoral evidence in vivo in several models of tumor cells and tumors.

The antitumor activity included: antiproliferative effects (cell cycle arrest), decreased viability and cell death by toxicity, apoptosis, necrosis, autophagy, as well as antiangiogenic and antimigratory effects.

 Antitumoral evidence included: reduction in tumor size, antiangiogenic, and antimetastatic effects.

 Additionally, most of the studies described that the canabinnoids exercised selective antitumoral action in several distinct tumor models. Thereby, normal cells used as controls were not affected.

The safety factor in the cannabinoids’ administration has also been demonstrated in vivo.

 The various cannabinoids tested in multiple tumor models showed antitumoral effects both in vitro and in vivo.

 These findings indicate that cannabinoids are promising compounds for the treatment of gliomas.”

Cannabidiol, a non-psychoactive cannabinoid compound, affects metalloproteinases and pro-survival intracellular pathways in u87-mg human glioma cell line

“Malignant gliomas are the most common primary brain tumors… Recently, we have shown that the non-psychoactive cannabinoid compound cannabidiol (CBD) induced apoptosis of human glioma cells in vitro and tumor regression in vivo…the present study was to investigate the anti-migratory action of CBD…

 In conclusion, the present investigation adds further insights into the antitumoral action of the non-psychoactive CBD, showing multiple mechanisms through which the cannabinoid inhibits glioma cell growth and motility.

As CBD is a natural compound without psychotropic and side effects, these data lead us to consider CBD as a new potential anticancer drug useful in the management of gliomas.”

Study: Marijuana’s Active Ingredient May Shrink Cancerous Tumors – FoxNews

“The active ingredient in marijuana appears to reduce tumor growth…

The researchers showed giving THC to mice with cancer decreased tumor growth and killed cells off in a process called autophagy.

“Our findings support that safe, therapeutically efficacious doses of THC may be reached in cancer patients,” Guillermo Velasco of Complutense University in Madrid and colleagues reported in the Journal of Clinical Investigation…

Other research has shown benefits, such as staving off Alzheimer’s, and many doctors view THC as a valuable way to treat weight loss associated with AIDS, and nausea and vomiting associated with chemotherapy in cancer patients.

Velasco and his team’s study included an analysis of two tumors from two people with a highly aggressive brain cancer which showed signs of autophagy after receiving THC.

The researchers said the findings could pave the way for cannabinoid-based drugs to treat cancer…”
