Cannabinoids Attenuate Cancer Pain and Proliferation in a Mouse Model

Logo of nihpa

“Oral cancer represents 3% of all cancers and its overall survival rate of 50% places it among the worst of all cancers

For many years cannabinoids have been used for medicinal and recreational purposes.

Recently, studies have focused on the therapeutic effects of cannabinoids on different cancers. The current study was the first to investigate the therapeutic effects of synthetic cannabinoids on oral cancer.

We investigated the effects of cannabinoid receptor agonists on (1) oral cancer cell viability in vitro and (2) oral cancer pain and tumor growth in a mouse cancer model.

Here we demonstrate the anti-nociceptive and anti-proliferative effects of systemic administration of cannabinoid receptor agonists on human oral cancer cells.

Our results suggest that systemic administration of cannabinoids decease oral cancer pain.

Our findings suggest a direct role for cannabinoid mechanisms in oral cancer pain and proliferation.

The systemic administration of cannabinoid receptor agonists may have important therapeutic implications wherein cannabinoid receptor agonists may reduce morbidity and mortality of oral cancer.

The present findings suggest that cannabinoid treatment may be a promising alternative therapy for oral cancer pain management. Furthermore, CBr2 agonism is not only palliative, but it may also be effective in inhibiting oral cancer growth, making the agonist a particularly desirable therapeutic agent.”

“Warning: Many alternative treatments are shams with zero proof. Most alternatives make claims that are not backed up by any evidence or hard empirical medical studies, are are not peer-reviewed. 
 
Peer review means your study and its claims will be vetted by a panel of the best doctors and other medical professionals in that field, for critical review. They will try to find fault in its methodology before publication and its recommendations for possible human treatment.
 
For any cannabis-based study strong enough to stand up to this critical review, and for it to be published in a major journal within such a field as cancer research, is incredible. That’s exactly how strong the evidence for cannabis medicine is starting to become.
 
Imagine that. This plant, this “great friend of humanity” which has helped us survive by giving early humans food, fuel, fiber and medicine, and who ancient healers wrote about in 6000 B.C., more than 8,000 years ago, is now coming back to prove itself and to help save us again.
 
And this time we are starting to find the evidence to back up the claims made for this plant over the centuries…”
 

Cannabis Science Reports Cancer Tumors Continues to Shrink and Die as Apparent Pieces of the Dying Cancer Tumors Begin to Fall off as Evidenced in Newest Photos of the 3rd Squamous Cell Carcinoma Patient

“Cannabis Science, Inc. a pioneering U.S. biotech company developing pharmaceutical cannabis (marijuana) products, is pleased to release new updated photos from the 3rd cancer patient self-administering cannabis extracts. This patient has severe squamous cell carcinoma on their head that was resistant to chemo and radiation therapy, which left the patient with large tumor masses on their head. With these new photo updates you can see the drastic change in appearance of the tumors and how the topical cannabis extract is killing them. 

Cannabis Science has been working very closely with this patient and is continuing to see vast improvement to his treatment resistant squamous cell carcinoma. Prior to using cannabis-based extracts this patient had received radiation and chemotherapy for his condition. This patient notices a huge difference between the treatments and had stated, “While on radiation treatments, each day was stressful and after each treatment I felt horrible as if my entire body was dying organ by organ. While using the Oil, I have noticed that my overall health seems much better. I sleep the recommended hours, unlike the insomnia I suffered while on radiation, and unlike the radiation that caused the restless sleep and nightmares, on the Oil I sleep like a baby.” The patient also mentioned that while showering they would see bits and pieces of the tumor falling off with the water as he was cleaning his head.

This patient is very pleased with the results of the topical cannabis extract so far and said he enjoyed absolutely nothing about radiation and felt constantly sick and just overall unhealthy, but with using the oil he said, “I feel myself being restored, not tortured.””

Marijuana May Cure PTSD – NBC

“Veterans suffering from post traumatic stress disorder may find help through marijuana.”

Cannabis Cup Cake Anyone?
  

“Could cannabis cure PTSD?

Post-traumatic stress disorder, which can also affect civilians who undergo a traumatic episode, may be cured by using marijuana, according to an East Bay Express report.

A researcher at Yale University is conducting a long-term study with 120 people — veterans with “intractable cases of PTSD” — who he thinks can be cured of their dehabilitating condition with marijuana.

Most people suffering from PTSD go through a regimen of drugs or more-invasive “exposure therapy,” in which they dig as deeply as possible into their trauma for 12 weeks. Most drop out in Week 3, according to the report.

The theory of R. Andrew Sewell is that tetrahydrocannabinol, or THC, one of the active ingredients in cannabis, can help the brain learn new information. This in turn helps people suffering from PTSD forget the old — as in bad — information.

This is called “extinction learning,” Sewell says. And such learning is made easier when a “switch” in the brain called CB1 is activated. It turns out cannabis is very good at activating the CB1 receptor.

“We’re talking about a cure,” said Sewell, who noted that after treatment, no drugs — not cannabis and not antidepressants — would be required.”

Cannabinoids.

“Since the discovery of an endogenous cannabinoid system, research into the pharmacology and therapeutic potential of cannabinoids has steadily increased. Two subtypes of G-protein coupled cannabinoid receptors, CB(1) and CB(1), have been cloned and several putative endogenous ligands (endocannabinoids) have been detected during the past 15 years. The main endocannabinoids are arachidonoyl ethanolamide (anandamide) and 2-arachidonoyl glycerol (2-AG), derivatives of arachidonic acid, that are produced “on demand” by cleavage of membrane lipid precursors.

 Besides phytocannabinoids of the cannabis plant, modulators of the cannabinoid system comprise synthetic agonists and antagonists at the CB receptors and inhibitors of endocannabinoid degradation. Cannabinoid receptors are distributed in the central nervous system and many peripheral tissues, including immune system, reproductive and gastrointestinal tracts, sympathetic ganglia, endocrine glands, arteries, lung and heart. There is evidence for some non-receptor dependent mechanisms of cannabinoids and for endocannabinoid effects mediated by vanilloid receptors.

Properties of CB receptor agonists that are of therapeutic interest include analgesia, muscle relaxation, immunosuppression, anti-inflammation, antiallergic effects, improvement of mood, stimulation of appetite, antiemesis, lowering of intraocular pressure, bronchodilation, neuroprotection and antineoplastic effects. The current main focus of clinical research is their efficacy in chronic pain and neurological disorders. CB receptor antagonists are under investigation for medical use in obesity and nicotine addiction. Additional potential was proposed for the treatment of alcohol and heroine dependency, schizophrenia, conditions with lowered blood pressure, Parkinson’s disease and memory impairment in Alzheimer’s disease.”

Study: Oral THC Administration Mitigates Sleep Apnea

“The oral administration of synthetic THC reduces symptoms of sleep apnea, according to clinical trial data published online in the scientific journal Frontiers in Psychiatry. Sleep apnea is a medical disorder characterized by frequent interruptions in breathing of up to ten seconds or more during sleep. The condition is associated with numerous physiological disorders, including fatigue, headaches, high blood pressure, irregular heartbeat, heart attack and stroke.

Investigators at the University of Illinois at Chicago, Department of Medicine assessed the safety, tolerability, and efficacy of dronabinol (oral THC in sesame seed oil) in 17 subjects with Obstructive Sleep Apnea.

Oral THC administration was associated with a significant change in Apnea Hypopnea Index over a 21-day period. Authors further determined dronabinol treatment to be safe and well tolerated.

They concluded, “These findings should be confirmed in a larger study in order to identify sub-populations with OSA that may benefit from cannabimimetic pharmacologic therapy.”

Dronabinol, marketed under the trade name Marinol, is FDA-approved to treat nausea and vomiting caused by chemotherapy.”

Proof of Concept Trial of Dronabinol in Obstructive Sleep Apnea

“… Δ9-TetraHydroCannabinol (Δ9THC) stabilizes autonomic output during sleep, reduces spontaneous sleep-disordered breathing, and blocks serotonin-induced exacerbation of sleep apnea. On this basis, we examined the safety, tolerability, and efficacy of dronabinol (Δ9THC), an exogenous Cannabinoid type 1 and type 2 (CB1 and CB2) receptor agonist in patients with Obstructive Sleep Apnea (OSA)…

Conclusion: Dronabinol treatment is safe and well-tolerated in OSA patients at doses of 2.5–10mg daily and significantly reduces AHI in the short-term. These findings should be confirmed in a larger study in order to identify sub-populations with OSA that may benefit from cannabimimetic pharmacologic therapy…

This proof of concept study demonstrates that dronabinol is safe, well-tolerated, and reduces AHI by approximately a third over 3 weeks of oral administration. Dronabinol treatment may be a viable alternative or adjunctive therapy in selected patients with OSA.”

Nuvilex Reports Cannabinoid-Based Pancreatic Cancer Treatments to be Developed by Its Subsidiary, Medical Marijuana Sciences, Inc.

“Nuvilex, Inc. (OTCQB:NVLX), international biotechnology and clinical stage provider of natural products and cell and gene therapy solutions for the treatment of diseases, announced today its subsidiary, Medical Marijuana Sciences, Inc., is planning to develop treatments for pancreatic cancer based on cannabinoids from Cannabis sativa.

In 2006, in a publication in the prestigious scientific journal Cancer Research, cannabinoids were reported to cause the death of pancreatic cells in laboratory and animal studies; these results were also seen with human pancreatic cancer cells implanted in mice whose immune systems were suppressed. Since then, laboratory studies have shown that when gemcitabine (Gemzar®), the only drug approved by the FDA as a single agent for the treatment of advanced pancreatic cancer, was combined with three different cannabinoids (each used singly), the growth inhibition was more than additive for six different pancreatic cancer cell lines. When these studies were done with human pancreatic cancer cells in immunosuppressed mice, the antitumor effectiveness of gemcitabine was greatly enhanced. These results, combined with those from other studies not mentioned here, indicate the important potential for developing treatments for pancreatic cancer that include the use of cannabinoids.”

[Cannabinoids for symptomatic therapy of multiple sclerosis].

“Spasticity represents a common troublesome symptom in patients with multiple sclerosis (MS). Treatment of spasticity remains difficult, which has prompted some patients to self-medicate with and perceive benefits from cannabis. Advances in the understanding of cannabinoid biology support these anecdotal observations.

Various clinical reports as well as randomized, double-blind, placebo-controlled studies have now demonstrated clinical efficacy of cannabinoids for the treatment of spasticity in MS patients. Sativex is a 1:1 mix of delta-9-tetrahydocannabinol and cannabidiol extracted from cloned Cannabis sativa chemovars, which recently received a label for treating MS-related spasticity in Germany.

The present article reviews the current understanding of cannabinoid biology and the value of cannabinoids as a symptomatic treatment option in MS.”
