Federal Government Reports Marijuana Effective in Combatting Certain Cancers Reports ADSI – NBC News

“LOS ANGELES, March 12, 2013 (GLOBE NEWSWIRE) — The following is a statement by Advocates for the Disabled and Seriously Ill:

In a recent report, the National Cancer Institute (NCI), part of the Federal government’s National Institutes of Health (NIH), stated that marijuana “inhibited the survival of both estrogen receptor–positive and estrogen receptor–negative breast cancer cell lines.” The same report showed marijuana slows or stops the growth of certain lung cancer cells and suggested that marijuana may provide “risk reduction and treatment of colorectal cancer.”

Referring to the NCI report, Patient Rights attorney Matthew Pappas said, “The Federal government’s continuing attack on people prescribed medical cannabis by their doctors is hypocritical considering the benefits reported by its own National Cancer Institute.” Pappas represents patients in defending their right to reasonably obtain medical marijuana. The patients contend the Federal government and various municipalities are trying to prevent them from obtaining cannabis for medical purposes in direct contravention of state laws. “Cities that ban dispensaries are denying patients the ability to obtain a medicine the Federal government’s National Institutes of Health says fights cancer and they’re doing it with the Obama Administration’s help.” Recently, the City of Los Angeles repealed its ban of medical marijuana collectives after Bill Rosendahl, a member of its city council diagnosed with cancer and prescribed medical marijuana said to fellow council members about the ban, “You want to kill me? You want to throw me under the bus?”

The NCI report also examined whether patients who smoke marijuana rather than ingesting it orally are exposed to a higher risk of lung and certain digestive system cancers. According to the government, 19 studies “failed to demonstrate statistically significant associations between marijuana inhalation and lung cancer.” The report also identified a separate study of 611 lung cancer patients that showed marijuana was “not associated with an increased risk of lung cancer or other upper aerodigestive tract cancers and found no positive associations with any cancer type.” In the area of prostate cancer, the NCI report was inconclusive and suggested further research was necessary. In its report, the National Cancer Institute also identified a “study of intratumoral injection of delta-9-THC in patients with recurrent glioblastoma” that showed tumor reduction in the test participants.

Despite the Federal government sanctioned and authorized NCI report, Pappas said Congress and the Obama Administration have continued to thwart marijuana research. In an announced effort to displace state medical marijuana laws, the Office of National Drug Control Policy described “medical” marijuana as a “myth” fueling “troubling misconceptions” in documents found on its website. The Federal government appears to be focused on creating more chemical drugs, many of which are the subject of various attorney television commercials seeking out those adversely impacted by those drugs. Pappas said both the Drug Enforcement Administration and the Office of National Drug Control Policy continue to assert marijuana lacks any medicinal value despite the research showing cannabis reduces certain cancer risks and inhibits the growth of tumor cells. He also commented that the Federal government’s anti-marijuana position contributes to and encourages prejudice and public misconception about the legitimate use of medical cannabis as treatment for seriously ill patients.

In addition to anti-cancer properties, separate research reported marijuana appears to have “profound nerve-protective and brain-enhancing properties that could potentially treat many neurodegenerative disorders.” In its report, the National Cancer Institute stated cannabis effectively treats insomnia and referenced a placebo-controlled study in cancer patients showing increased quality of sleep and relaxation in those treated with tetrahydrocannabinol, an active component in marijuana.

Responding to a White House statement that only a small percentage of patients prescribed medical cannabis under state laws use it to treat cancer, Pappas said “marijuana isn’t just for cancer or AIDS patients – it can also treat, for example, sleeplessness.” Although generally not a life threatening condition, Pappas referred to insomnia as a health issue regularly treated with prescription drugs zolpidem (brand name Ambien) and eszopiclone (brand name Lunesta). According to their manufacturers’ websites, zolpidem and eszopiclone have been shown to cause severe side effects including aggressiveness, hallucinations, confusion, or suicidal thoughts. Pappas noted that, unlike those drugs, studies on insomnia similar to those reported by the National Cancer Institute show medical marijuana effectively treats insomnia at a far lower cost and with fewer side effects. Marijuana has also been prescribed for glaucoma, multiple sclerosis, chronic pain, and a variety of other physical and mental conditions.

Addressing the White House website statement that medical marijuana should remain criminally illegal under federal law, Pappas said that “with every drug, the doctor must consider the benefits versus any possible side effects. In its 3000-plus year history of medicinal use, there has never been a known, confirmed death caused by overdose of marijuana. To suggest that prescription drugs known to have severe negative side effects are alright and that marijuana can only be used for cancer or AIDS is nonsensical. It demonstrates how the Federal government’s decision to usurp state sovereignty is harming people because burdening citizens with federal criminal records based on medical marijuana provided for under state law is simply wrong. To continue outlawing the use of a drug shown to have life-saving, anti-cancer benefits that has been used safely as a medication for thousands of years is irresponsible.”

Cannabinoid Receptor 2-Mediated Attenuation of CXCR4-Tropic HIV Infection in Primary CD4+ T Cells

“Agents that activate cannabinoid receptor pathways have been tested as treatments for cachexia, nausea or neuropathic pain in HIV-1/AIDS patients… Cannabinoid agonists activate the CB1R and CB2R cannabinoid receptors…

Cannabinoid agonists are currently under investigation for the treatment of AIDS-associated cachexia, nausea, and neuropathic pain. One such drug, dronabinol (Δ9-THC; Marinol®), has won Food and Drug Administration (FDA) approval for treatment of HIV-associated anorexia. Additionally, the prescription of smoked or ingested cannabis (marijuana) for treatment of AIDS-related symptoms has been approved…. Despite the use of cannabinoids by HIV/AIDS patients, few studies have investigated the impact of such drugs in regard to viral pathogenesis or immune regulation…

….Indeed, both smoked marijuana and dronabinol were reported to increase total CD4+ T cell number and naïve T cell number over a 21-day period. A decrease in viral load was also observed in these patients. Similarly, in SIV infected rhesus macaques, Δ9-THC exposure reduced viral load and CD4+ T cell depletion, significantly increasing animal survival over an 11 month period.

. Our findings suggest that CB2R activation in CD4+ T cells can inhibit actin reorganization and impair productive infection following cell-free or cell-associated viral acquisition of CXCR4-tropic HIV-1 in resting cells.

Therefore, the clinical use of CB2R agonists in the treatment of AIDS symptoms may also exert beneficial adjunctive antiviral effects against CXCR4-tropic viruses in late stages of HIV-1 infection.

Further study of cannabinoids and other neuroendocrine regulators that selectively modulate immune function may result in the discovery of new anti-viral drugs that can also mitigate AIDS-associated symptoms.”

Cannabinoid Inhibition of Macrophage Migration to the Trans-Activating (Tat) Protein of HIV-1 Is Linked to the CB2 Cannabinoid Receptor

“Macrophage-like cells are primary targets for infection by HIV-1…  In the present study, the exogenous cannabinoids δ-9-tetrahydrocannabinol (THC) and (−)-cis-3-[2-hydroxy-4-(1,1-dimethylheptyl)phenyl]-trans-4-(3-hydroxypropyl) cyclohexanol (CP55940) were shown to significantly inhibit migration of human U937 macrophage-like cells to the Tat protein in a concentration-related manner….

Collectively, the pharmacological and biochemical knockdown data indicate that cannabinoid-mediated modulation of macrophage migration to the HIV-1 Tat protein is linked to the CB2 cannabinoid receptor. Furthermore, these results suggest that the CB2 cannabinoid receptor has potential to serve as a therapeutic target for ablation of HIV-1-associated untoward inflammatory response…

,,, the CB2 receptor has the potential to serve as a molecular target for ablating hyperinflammatory responses of macrophage-like cells while avoiding untoward psychotropic effects caused by activation of the CB1 receptor.

 In conclusion, the immunosuppressive and anti-inflammatory properties of select cannabinoids may have profound therapeutic potential in moderating HIV-associated immunopathology, including microglial activation, chemokine/cytokine dysregulation, and monocyte infiltration in the CNS.”

Attenuation of HIV-1 replication in macrophages by cannabinoid receptor 2 agonists.

“Previous studies showed that activation of the CB2 can attenuate inflammatory responses and affect HIV-1 infectivity in T cells and microglia. Here, we report that CB2 agonists can also act as immunomodulators on HIV-1-infected macrophages.

   We speculate that these findings indicate that prevention of viral entry is not a central mechanism for CB2-mediated suppression in viral replication.

However, CB2 may affect the HIV-1 replication machinery.

Results from a single-round infection with the pseudotyped virus revealed a marked decrease in HIV-1 LTR activation by the CB2 ligands.

Together, these results indicate that CB2 may offer a means to limit HIV-1 infection in macrophages.”

Cannabinoids may be therapeutic in breast cancer.

“Cannabinoids are a group of compounds synthesized exclusively by the Cannabis sativa plant, commonly known as marijuana. In 1990, the first cannabinoid-specific membrane (CB1) was characterized and cloned (Matsuda, Lolait, Brownstein, Young, & Bonner, 1990), which catapulted biomedical research on these unique compounds.

 Cannabinoids refer to both marijuana-derived compounds with the active ingredient of 9-tetrahydrocannabinol (THC) and also the synthetic molecules that activate the same primary targets as THC.

Therapeutic properties of marijuana have been well established; however, the clinical use of either plant-sourced or pure cannabinoids remains limited.

The anticachexia properties of cannabinoids are found in tetrahydrocannabinol (oral capsules of synthetically generated THC) and are used to manage weight loss, wasting syndrome, and nausea and vomiting associated with cancer treatment.”
