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 Recently, the City of Los Angeles repealed its ban of medical marijuana collectives after Bill Rosendahl, a member of its city council diagnosed with cancer and prescribed medical marijuana said to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 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.”

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.”

Cannabidiol, a constituent of Cannabis sativa, modulates sleep in rats.

“Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and cannabidiol (CBD) are two major constituents of Cannabis sativa. Delta(9)-THC modulates sleep, but no clear evidence on the role of CBD is available.

In order to determine the effects of CBD on sleep, it was administered intracerebroventricular (icv) in a dose of 10 microg/5 microl at the beginning of either the lights-on or the lights-off period. We found that CBD administered during the lights-on period increased wakefulness (W) and decreased rapid eye movement sleep (REMS). No changes on sleep were observed during the dark phase. Icv injections of CBD (10 microg/5microl) induced an enhancement of c-Fos expression in waking-related brain areas such as hypothalamus and dorsal raphe nucleus (DRD). Microdialysis in unanesthetized rats was carried out to characterize the effects of icv administration of CBD (10 microg/5 microl) on extracellular levels of dopamine (DA) within the nucleus accumbens. CBD induced an increase in DA release. Finally, in order to test if the waking properties of CBD could be blocked by the sleep-inducing endocannabinoid anandamide (ANA), animals received ANA (10 microg/2.5 microl, icv) followed 15 min later by CBD (10 microg/2.5 microl). Results showed that the waking properties of CBD were not blocked by ANA.

 In conclusion, we found that CBD modulates waking via activation of neurons in the hypothalamus and DRD. Both regions are apparently involved in the generation of alertness. Also, CBD increases DA levels as measured by microdialysis and HPLC procedures.

Since CBD induces alertness, it might be of therapeutic value in sleep disorders such as excessive somnolence.”

The role of the CB1 receptor in the regulation of sleep.

“During the 1990s, transmembranal proteins in the central nervous system (CNS) that recognize the principal compound of marijuana, the delta-9-tetrahydrocannabinol (Delta9-THC) were described. The receptors were classified as central or peripheral, CB1 and CB2, respectively. To this date, it has been documented the presence in the CNS of specific lipids that bind naturally to the CB1/CB2 receptors.

The family of endogenous cannabinoids or endocannabinoids comprises oleamide, arachidonoylethanolamine, 2-arachidonylglycerol, virodhamine, noladin ether and N-arachidonyldopamine. Pharmacological experiments have shown that those compounds induce cannabimimetic effects. Endocannabinoids are fatty acid derivates that have a variety of biological actions, most notably via activation of the cannabinoid receptors. The endocannabinoids have an active role modulating diverse neurobiological functions, such as learning and memory, feeding, pain perception and sleep generation.

Experimental evidence shows that the administration of Delta9-THC promotes sleep.

 The activation of the CB1 receptor leads to an induction of sleep, this effect is blocked via the selective antagonist.

Since the system of the endogenous cannabinoids is present in several species, including humans, this leads to the speculation of the neurobiological role of the endocannabinoid system on diverse functions such as sleep modulation.

This review discusses the evidence of the system of the endocannabinoids as well as their physiological role in diverse behaviours, including the modulation of sleep.”

Can Medical Marijuana Help With Sleep Apnea

“A medical disorder characterized by frequent interruptions in breathing of up to 10 seconds or more during sleep, sleep apnea, is associated with many physiological disorders, including fatigue, headaches, high blood pressure, irregular heartbeat, heart attack, and stroke…

In the June issue of the American Academy of Sleep Medicine Journal, researchers at the University of Illinois, Department of Medicine reported that sleep apnea in rats that received cannabinoids (natural chemicals of cannabis) was deleted. Doses of delta-9-THC and stabilized polyamide breathing during sleep and blocked serotonin-induced exacerbation of sleep apnea. Many patients who have used the ratio of medical cannabis improved sleep quality and less fatigue the next day.”

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.”

Functional role for cannabinoids in respiratory stability during sleep.

“Serotonin, acting in the peripheral nervous system, can exacerbate sleep-related apnea, and systemically administered serotonin antagonists reduce sleep-disordered respiration in rats and bulldogs. Because cannabinoid receptor agonists are known to inhibit the excitatory effects of serotonin on nodose ganglion cells, we examined the effects of endogenous (oleamide) and exogenous (delta9-tetrahydrocannabinol; delta9THC) cannabimimetic agents on sleep-related apnea…

Our data show that delta9THC and oleamide each stabilized respiration during all sleep stages… This observation suggests an important role for endocannabinoids in maintaining autonomic stability during sleep…

CONCLUSIONS:

This study demonstrates potent suppression of sleep-related apnea by both exogenous and endogenous cannabinoids. These findings are of relevance to the pathogenesis and pharmacological treatment of sleep-related breathing disorders.”

The effects of cannabidiol on the antigen-induced contraction of airways smooth muscle in the guinea-pig.

“(-)-Δ(9)-Tetrahydrocannabinol has been demonstrated to have beneficial effects in the airways, but its psychoactive effects preclude its therapeutic use for the treatment of airways diseases. In the present study we have investigated the effects of (-)-cannabidiol, a non-psychoactive component of cannabis for its actions on bronchial smooth muscle in vitro and in vivo.

 Guinea-pig bronchial smooth muscle contractions induced by exogenously applied spasmogens were measured isometrically. In addition, contractile responses of bronchial smooth muscle from ovalbumin-sensitized guinea-pigs were investigated in the absence or presence of (-)-cannabidiol. Furthermore, the effect of (-)-cannabidiol against ovalbumin-induced airway obstruction was investigated in vivo in ovalbumin-sensitized guinea pigs. (-)-Cannabidiol did not influence the bronchial smooth muscle contraction induced by carbachol, histamine or neurokinin A. In contrast, (-)-cannabidiol inhibited anandamide- and virodhamine-induced responses of isolated bronchi. A fatty acid amide hydrolase inhibitor, phenylmethanesulfonyl fluoride reversed the inhibitory effect of (-)-cannabidiol on anandamide-induced contractions. In addition, (-)-cannabidiol inhibited the contractile response of bronchi obtained from allergic guinea-pigs induced by ovalbumin. In vivo, (-)-cannabidiol reduced ovalbumin-induced airway obstruction.

 In conclusion, our results suggest that cannabidiol can influence antigen-induced airway smooth muscle tone suggesting that this molecule may have beneficial effects in the treatment of obstructive airway disorders.”

[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.”
