Non-Hallucinogenic Cannabinoids Are Effective Anti-Cancer Drugs – ScienceDaily

“New research has shown that the non-hallucinogenic components of cannabis could act as effective anti-cancer agents.

The anti-cancer properties of tetrahydrocannabinol (THC), the primary hallucinogenic component of cannabis, has been recognised for many years, but research into similar cannabis-derived compounds, known as cannabinoids, has been limited.

The study was carried out by a team at St George’s, University of London. It has been published in the journal Anticancer Research.

The team, led by Dr Wai Liu and colleagues carried out laboratory investigations using a number of cannabinoids, either alone or in combination with each other, to measure their anti-cancer actions in relation to leukemia.

Of six cannabinoids studied, each demonstrated anti-cancer properties as effective as those seen in THC. Importantly, they had an increased effect on cancer cells when combined with each other.”

“Marijuana has become more widely studied recently for its medicinal properties, but the area is no longer limited to people suffering from pain, nausea, vomiting, anxiety, sleeplessness or disease-induced anorexia. It has now been discovered that breast cancer patients are helped with marijuana through direct anticancer actions that the cannabis species is able to provide.”

“Debate is just beginning in Washington over how medical marijuana will be grown and distributed now that the rules for the recreational market are established. Meanwhile, research into medical benefits of compounds within the cannabis plant continues to show effectiveness.

Effectiveness against pain in its many forms and other side effects of major diseases – or the palliative side of marijuana use – have been pretty well established, but can marijuana directly take on a disease as big, scary and deadly as cancer?

“What we’ve shown using just a few of these (cannabis) compounds is that the effects against cancer are really profound. They really are,” said Dr. Wai Liu, a senior research fellow at St George’s University of London.

Anticancer success

Quick note: Cannabinoids are the chemicals in marijuana that have effects in the body, some have psychoactive (or make you high) effects such as THC, and others such as CBD don’t have psychoactive effects but do interact with the body’s “cannabinoid receptors.” There are more than 85 “cannabinoids” in marijuana.

Liu’s most recent published research “explored the activity of six cannabinoids, used both alone and in combination in leukaemic cells.” The research was published in Anticancer Research: International Journal of Cancer Research and Treatment.

He said the anticancer activity of THC has been “known for sometime” but that THC’s psychoactive effect or tendency to get you high limits its use as a cancer-fighting agent. That’s partly due to the negative social stigma about getting high and, of course, not everyone wants to experience a high.

So, he set out to explore the cancer fighting ability of other cannabinoids that don’t get you high.

“We have shown that these six other agents that lack psychoactivity are also just as effective as an anti-cancer agent,” he said. Chief among the six was cannabidiol or CBD.”

Non-Hallucinogenic Cannabinoids Could Cure Cancer: Is A Cheap Anti-Cancer Drug On The Way?

Non-Hallucinogenic Cannabinoids

“Studies that support marijuana’s medicinal properties are met with a great deal of skepticism due to cannabis’ hallucinogenic effects. Researchers from St. George’s University of London have isolated six non-hallucinogenic cannabinoids that could lead to the development of effective anti-cancer medication.

“This study is a critical step in unpicking the mysteries of cannabis as a source of medicine,” explained the study’s lead researcher, Dr. Wai Liu. “The cannabinoids examined have minimal, if any, hallucinogenic side effects, and their properties as anti-cancer agents are promising.””

Cannabidiol in Humans-The Quest for Therapeutic Targets.

“Cannabidiol (CBD), a major phytocannabinoid constituent of cannabis, is attracting growing attention in medicine for its anxiolytic, antipsychotic, antiemetic and anti-inflammatory properties.

However, up to this point, a comprehensive literature review of the effects of CBD in humans is lacking. The aim of the present systematic review is to examine the randomized and crossover studies that administered CBD to healthy controls and to clinical patients.

A systematic search was performed in the electronic databases PubMed and EMBASE using the key word “cannabidiol”. Both monotherapy and combination studies (e.g., CBD + ∆9-THC) were included. A total of 34 studies were identified: 16 of these were experimental studies, conducted in healthy subjects, and 18 were conducted in clinical populations, including multiple sclerosis (six studies), schizophrenia and bipolar mania (four studies), social anxiety disorder (two studies), neuropathic and cancer pain (two studies), cancer anorexia (one study), Huntington’s disease (one study), insomnia (one study), and epilepsy (one study).

Experimental studies indicate that a high-dose of inhaled/intravenous CBD is required to inhibit the effects of a lower dose of ∆9-THC. Moreover, some experimental and clinical studies suggest that oral/oromucosal CBD may prolong and/or intensify ∆9-THC-induced effects, whereas others suggest that it may inhibit ∆9-THC-induced effects.

Finally, preliminary clinical trials suggest that high-dose oral CBD  may exert a therapeutic effect for social anxiety disorder, insomnia and epilepsy, but also that it may cause mental sedation. Potential pharmacokinetic and pharmacodynamic explanations for these results are discussed.”

Molecular Mechanisms Involved in the Antitumor Activity of Cannabinoids on Gliomas: Role for Oxidative Stress.

“Cannabinoids, the active components of Cannabis sativa, have been shown to exert antiproliferative and proapoptotic effects on a wide spectrum of tumor cells and tissues.

Of interest, cannabinoids have displayed great potency in reducing the growth of glioma tumors, one of the most aggressive CNS tumors, either in vitro or in animal experimental models curbing the growth of xenografts generated by subcutaneous or intrathecal injection of glioma cells in immune-deficient mice.

Cannabinoids appear to be selective antitumoral agents as they kill glioma cells without affecting the viability of non-transformed cells.

This review will summarize the anti-cancer properties that cannabinoids exert on gliomas and discuss their potential action mechanisms that appear complex, involving modulation of multiple key cell signaling pathways and induction of oxidative stress in glioma cells.” http://www.ncbi.nlm.nih.gov/pubmed/24281104

“The therapy of gliomas, the most frequent class of malignant primary brain tumors and one of the most aggressive forms of cancer characterized by high invasiveness, a high proliferation rate and rich neovascularization, could benefit from the use of cannabinoids, the active compounds of Cannabis sativa, and their synthetic derivatives. They have been shown to mimic the endogenous substances named “endocannabinoids” that activate specific cannabinoid receptors (CB1 and CB2).

Cannabinoids have been proven to inhibit glioma tumor growth in either in vitro or in vivo models through several cellular pathways such as elevating ceramide levels, modulating PI3K/Akt, MAPK kinases, inducing autophagy and oxidative stress state in glioma cells, thus arresting cell proliferation and inducing apoptosis. Since cannabinoids kill tumor cells without toxicity on their non transformed counterparts, probably modulating the cell survival/cell death pathways differently, they can represent a class of new potential anticancer drugs.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3835116/

The endocannabinoid system, cannabinoids, and pain.

“The endocannabinoid system is involved in a host of homeostatic and physiologic functions, including modulation of pain and inflammation… Exogenous plant-based cannabinoids (phytocannabinoids) and chemically related compounds, like the terpenes, commonly found in many foods, have been found to exert significant analgesic effects in various chronic pain conditions.

Currently, the use of Δ9-tetrahydrocannabinol is limited by its psychoactive effects and predominant delivery route (smoking), as well as regulatory or legal constraints.

 However, other phytocannabinoids in combination, especially cannabidiol and β-caryophyllene, delivered by the oral route appear to be promising candidates for the treatment of chronic pain due to their high safety and low adverse effects profiles.

This review will provide the reader with the foundational basic and clinical science linking the endocannabinoid system and the phytocannabinoids with their potentially therapeutic role in the management of chronic pain.”

“…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.”

“Cannabis is now apparently the cure for everything from cancer,  diarrhea, bipolar disorder and Multiple sclerosis, to an ailing economy and being a smart aleck teenager. The latest chronic illness to get the 4:20 treatment is epilepsy. British scientists from the University of Reading tested a compound in pot called cannabidivarin on rats and mice with six types of epilepsy, and found it “strongly suppressed seizures” without the unpleasant side effects of current anti-epilepsy drugs. With 1 percent of the world’s population suffering from the disease, the head of the research team, Ben Whalley, says there’s a pressing need for better treatments. “It’s a chronic condition with no cure and currently, in around one-third of cases, the currently available treatments do not work, cause serious side effects and increase fatalities,” he said.”
