Medicinal Marijuana Cannabis Research Suppressed
by Jeffrey Dach MD
Although cannabis was a medicinal plant for thousands of years, its medical use was suppressed and banned throughout most of the 20th century. Banned in England, Canada and the US in the 1930’s, medical cannabis represents the first casualty in a war against natural medicine waged by the pharmaceutical industry. Even today research efforts are suppressed by our own government. Over the last two decades, there have been major scientific breakthroughs in cannabis research outside the US in Israel, Spain, Italy and Brazil. These breakthroughs have made cannabis “the wonder drug of the 21st century”.

The Father of Medical Cannabis Research
The greatest cannabis researcher is unquestionably Raphael Mechoulam from Israel. He discovered THC in 1964, the psycho-active component of cannabis. Mechoulam also discovered the first endogenous endo-cannabinoid in 1992, Anandamide, a sanskrit word translated as “bliss”.

A Treasure Trove Waiting for Discovery
When asked why he devoted his entire lifetime studying the biochemistry of cannabis, Dr. Raphael Mechoulam said the following:
“The three major illicit drugs derived from plants were then (at the beginning of my career), and still are, opium, coca and cannabis. Morphine had been isolated from opium early in the 19th century and structure elucidated in the 1920s by Robert Robinson. Cocaine was isolated from coca leaves in the middle of the 19th century and structure described by Richard Willstatter in the last decade of the 19th century. I believe that the cannabinoids represented a medicinal treasure trove which waits to be discovered.”

Just Like the Opiate Receptor Story

In a story very similar to the discovery of opiate receptors in the brain, cannabinoid receptors have been discovered along with their endogenous cannabinoids, representing the largest neurotransmitter system in the brain and immune system. This neurotransmitter system went undetected for decades because it involves an unheard of concept, retrograde transmission, or reversed flow of information from the post synapse to the pre-synapse.
The Cannabinoid Receptor Story
In the 1970s, Morphine was isolated from the poppy and found to bind to opiate receptors in the brain. Scientists eventually discovered that people make their own opioids, called enkephalins and endorphins. Morphine simply hijacks the receptors for the brain’s opioids. It seemed likely that something similar was happening with THC and the cannabinoid receptors in the brain and the immune system. The health implications of the endo-cannabinoid system are staggering. Cannabinoids act as a bioregulatory mechanism for most life processes.
Medical Uses of Cannabinoids:
Relieves Chronic Pain
Reduces need for narcotics in chronic pain or Narcotics Addiction
Anti-Cancer (Breast, Colon, Pancreas, Brain-Glioma)
Relieves Post Traumatic Stress Disorder, Phobias
Relieves Nausea and Vomiting associated with Chemotherapy
Improves Appetite in Wasting Syndromes
Relieves Migraine Headache
Relieves Glaucoma
Relieves Bladder incontinence
Used as Anti-convulsant
Used as Anti-depressant
Used as Atypical anti-psychotic
Used for Bi-Polar Syndrome
Used for Multiple Sclerosis, ALS

Medical Marijuana More than 70% of voters support the right of patients to use marijuana with a doctor’s recommendation — including substantial majorities of Democrats, Republicans, and Independents.
One of the most egregious outcomes of marijuana prohibition is that many sick people cannot legally access the medicine that works best for them. For many seriously ill people, medical marijuana is the only medicine that relieves their pain and suffering, or treats symptoms of their medical condition, without debilitating side effects. Marijuana has been shown to alleviate symptoms of a huge variety of serious medical conditions including cancer, AIDS, and glaucoma, and is often an effective alternative to synthetic painkillers.

Cannabinoids represent a novel class of drugs active in increasing the life span mice carrying Lewis lung tumors and decreasing primary tumor size. In the present studies, the effects of delta9-THC, delta8-THC, and cannabidiol on tumor macromolecular biosynthesis were studied. These drugs inhibit thymidine-3H incorporation into DNA acutely, but did not inhibit leucine uptake into tumor protein. At 24 h after treatment, cannabinoids did not inhibit thymidine-3H incorporation into DNA, leucine-3H uptake into protein or cytidine-3H into RNA.

CANNABINOIDS: POTENTIAL ANTICANCER AGENTS by Manuel Guzmán Cannabinoids — the active components of Cannabis sativa and their derivatives — exert palliative effects in cancer patients by preventing nausea, vomiting and pain and by stimulating appetite. In addition, these compounds have been shown to inhibit the growth of tumour cells in culture and animal models by modulating key cell-signalling pathways. Cannabinoids are usually well tolerated, and do not produce the generalized toxic effects of conventional drugs.
Cannabinoids, the active components of Cannabis sativa and their derivatives, act in the organism by mimicking endogenous substances, the endocannabinoids, that activate specific cannabinoid receptors. Cannabinoids exert palliative effects in patients with cancer and inhibit tumour growth in laboratory animals.
The best-established palliative effect of cannabinoids in cancer patients is the inhibition of chemotherapy-induced nausea and vomiting. Today, capsules of 9-tetrahydrocannabinol (dronabinol (Marinol)) and its synthetic analogue nabilone (Cesamet) are approved for this purpose.
Cannabinoids inhibit tumour growth in laboratory animals. They do so by modulating key cell-signalling pathways, thereby inducing direct growth arrest and death of tumour cells, as well as by inhibiting tumour angiogenesis and metastasis.
Cannabinoids are selective antitumour compounds, as they can kill tumour cells without affecting their non-transformed counterparts. It is probable that cannabinoid receptors regulate cell-survival and cell-death pathways differently in tumour and non-tumour cells.
Cannabinoids have favourable drug-safety profiles and do not produce the generalized toxic effects of conventional chemotherapies.

Cannabinoids for Cancer Treatment: Progress and Promise. Sami Sarfaraz et al University of Wisconsin, Madison, Wisconsin
Cannabinoids are a class of pharmacologic compounds that offer potential applications as antitumor drugs, based on the ability of some members of this class to limit inflammation, cell proliferation, and cell survival. In particular, emerging evidence suggests that agonists of cannabinoid receptors expressed by tumor cells may offer a novel strategy to treat cancer. Here, we review recent work that raises interest in the development and exploration of potent, nontoxic, and nonhabit forming cannabinoids for cancer therapy. Cannabinoid Receptors:
“there is overwhelming evidence to suggest that cannabinoids can be explored as chemotherapeutic agents for the treatment of cancer. In view of the fair safety profile of most cannabinoids together with their antiproliferative action on tumor cells, clinical trials are required to determine whether cannabinoids could be used for the inhibition of tumor growth in a clinical setting. If this could be established, then one can hope that nontoxic, nonhabit forming cannabinoids could be developed as novel therapeutic agents for the treatment of cancer.”

Cannabinoids as Anti-Cancer Agents.
There is now abundant evidence that cannabinoids can inhibit tumor growth, in a variety of tumor types, both in vitro and in vivo (Guzman, 2003). The primary cannabinoids in cannabis, THC and cannabidiol, have also proven to be potent antioxidants (Hampson et al, 1998), which may reduce some types of cancers. Surprisingly, promising experimental results were first reported by Munson et al (1975) over a quarter or a century ago. Their results showed THC dose-dependent increase in survival time and inhibition of tumor growth in mice with Lewis lung adenocarcinoma, but were little pursued until recently, following the discovery of the cannabinoid receptors.

Marijuana has been used in medicine for millennia, but it was not until 1964 that delta9-tetrahydrocannabinol (delta9-THC), its major psychoactive component, was isolated in pure form and its structure was elucidated. Shortly thereafter it was synthesized and became readily available.
However, it took another decade until the first report on its antineoplastic activity appeared. In 1975, Munson discovered that cannabinoids suppress Lewis lung carcinoma cell growth. The mechanism of this action was shown to be inhibition of DNA synthesis. Antiproliferative action on some other cancer cells was also found. In spite of the promising results from these early studies, further investigations in this area were not reported until a few years ago, when almost simultaneously two groups initiated research on the antiproliferative effects of cannabinoids on cancer cells: Di Marzo’s group found that cannabinoids inhibit breast cancer cell proliferation, and Guzman’s group found that cannabinoids inhibit the growth of C6 glioma cell. Other groups also started work in this field, and today, a wide array of cancer cell lines that are affected is known, and some mechanisms involved have been elucidated.

A compound found in cannabis may stop breast cancer spreading throughout the body, US scientists believe. The California Pacific Medical Center Research Institute team are hopeful that cannabidiol or CBD could be a non-toxic alternative to chemotherapy. Unlike cannabis, CBD does not have any psychoactive properties so its use would not violate laws, Molecular Cancer Therapeutics reports. CBD works by blocking the activity of a gene called Id-1 which is believed to be responsible for the aggressive spread of cancer cells away from the original tumour site – a process called metastasis.

Endocannabinoids in endocrine and related tumours Maurizio Bifulco et al; Napoli, Italy
The ‘endocannabinoid system’, comprising the cannabinoid CB1 and CB2 receptors, their endogenous ligands, endocannabinoids and the enzymes that regulate their biosynthesis and degradation, has drawn a great deal of scientist attention during the last two decades. In particular, they are able to inhibit cell growth, invasion and metastasis of thyroid, breast and prostate tumours. The chief events of endocannabinoids in cancer cell proliferation are reported highlighting the correspondent signalling involved in tumour processes: regulation of adenylyl cyclase, cyclic AMP-protein kinase-A pathway and MEK-extracellular signal-regulated kinase signalling cascade.
“There is compelling evidence that endo/cannabinoids may regulate the growth and spread of normal and neoplastic tissues.”

Endocannabinoids as emerging suppressors of angiogenesis and tumor invasion (Review) MAURIZIO BIFULCO et al. Napoli, Italy August 7, 2006
The ‘endocannabinoid system’ is involved in a broad range of functions and in a
growing number of pathological conditions. There is increasing evidence that endocannabinoids are able to inhibit cancer cell growth in culture as well as in animal models.
However, endocannabinoids are now emerging as suppressors of angiogenesis and tumor spreading since they have been reported to inhibit angiogenesis, cell
migration and metastasis in different types of cancer, pointing to a potential role of the endocannabinoid system as a target for a therapeutic approach of such malignant diseases. The potential use of cannabinoids to retard tumor growth and spreading is even more appealing considering that they show a good safety profile, regarding toxicity, and are already used in cancer patients as palliatives to stimulate appetite and to prevent devastating effects such as nausea, vomiting and pain.

The endogenous cannabinoid anandamide inhibits human breast cancer cell proliferation. Luciano De Petrocellis and Vincenzo Di Marzo et al. Naples, Italy; The anti-proliferative effect of anandamide was not due to toxicity or to apoptosis of cells but was accompanied by a reduction of cells in the S phase of the cell cycle. In conclusion, we have shown that anandamide is a potent and selective inhibitor of the proliferation of HBC cells and that activation of a cannabinoid receptor, whose occurrence had never been described previously in these cells, is at least in part responsible for this effect.

Antitumor Activity of Plant Cannabinoids with Emphasis on the Effect of Cannabidiol on Human Breast Carcinoma. JPET 318:1375-1387, 2006
Vincenzo Di Marzo et al. Napoli, Italy
Cannabidiol is nonpsychotropic. Indeed, C. sativa contains at least 400 chemical components, of which 66 have been identified to belong to the class of the cannabinoids To date, cannabinoids have been successfully used in the treatment of nausea and vomiting (for review, see Robson, 2005), two common side effects that accompany chemotherapy in cancer patients. Nevertheless, the use of cannabinoids in oncology might be somehow underestimated since increasing evidence exist that plant, synthetic, and endogenous cannabinoids (endocannabinoids) are able to exert a growth-inhibitory action on various cancer cell types.
Results obtained in a panel of tumor cell lines clearly indicate that cannabidiol is the most potent inhibitor of cancer cell growth. Both cannabidiol and the cannabidiol-rich extract inhibited the growth of xenograft tumors obtained by s.c. injection into athymic mice of human MDA-MB-231 breast carcinoma or rat v-K-ras-transformed thyroid epithelial cells and reduced lung metastases deriving from intrapaw injection of MDA-MB-231 cells.
Judging from several experiments on its possible cellular and molecular mechanisms of action, we propose that cannabidiol lacks a unique mode of action in the cell lines investigated. At least for MDA-MB-231 cells, however, our experiments indicate that cannabidiol effect is due to its capability of inducing apoptosis via: direct or indirect activation of cannabinoid CB2. Our data support the further testing of cannabidiol and cannabidiol-rich extracts for the potential treatment of cancer.
In conclusion, our data indicate that cannabidiol, and possibly Cannabis extracts enriched in this natural cannabinoid, represent a promising nonpsychoactive antineoplastic strategy. In particular, for a highly malignant human breast carcinoma cell line, we have shown here that cannabidiol and a cannabidiol-rich extract counteract cell growth both in vivo and in vitro as well as tumor metastasis in vivo. Cannabidiol exerts its effects on these cells through a combination of mechanisms that include either direct or indirect activation of CB2 and TRPV1 receptors and induction of oxidative stress, all contributing to induce apoptosis.
Mice treated with either pure cannabidiol or the cannabidiol-rich extract exhibited significantly smaller tumors in comparison with control mice. A strong and statistically significant antitumor effect was observed

The long history of the medicinal use of Cannabis sativa and, more recently, of its chemical constituents, the cannabinoids, suggests that also the endogenous ligands of cannabinoid receptors, the endocannabinoids, and, particularly, their derivatives may be used as therapeutic agents.
In this article, we discuss the anti-tumor and anti-inflammatory activity of: (1) the endocannabinoids anandamide (arachidonoylethanolamide) and 2-arachidonoyl glycerol; (2) the bioactive fatty acid amides palmitoylethanolamide and oleamide; and (3) some synthetic derivatives of these compounds, such as the N-acyl-vanillyl-amines. Furthermore, the possible role of cannabimimetic fatty acid derivatives in the pathological consequences of cancer and inflammation, such as cachexia, wasting syndrome, chronic pain and local vasodilation, will be examined.

Legalizing marijuana makes sense, cents March 3, 2009 BY STEVE HUNTLEY Chicago Sun TImes. California Assemblyman Tom Ammiano of San Francisco, says licensing and taxing legal marijuana production and sales would earn California $1.3 billion a year. His bill would legalize marijuana possession and use for adults 21 or older, license commercial farming of it and tax it at $50 an ounce.
A like number of states have humane laws allowing marijuana smoking by people with chronic or terminal diseases to combat pain and nausea. New Jersey could become the 14th since its state senate has approved a medicinal bill.
the Obama administration says it will not continue the Bush administration’s policy of having U.S. Drug Enforcement Administration officers raid medical marijuana dispensaries. That reflects the simple fact a huge part of America thinks a medical ban is cruel and prohibition in general is silly.
A 2005 study endorsed by the late Milton Friedman and 530 other economists found legal regulation would save the nation $7.7 billion in enforcement costs and bring in up to $6.2 billion in taxes

Cannabidiol, a Cannabis sativa constituent, as an antipsychotic drug .
A.W. Zuardi, J.A.S. Crippa, J.E.C. Hallak, F.A. Moreira and F.S. Guimarães
Universidade de São Paulo, Ribeirão Preto, SP, Brasil
A high dose of Δ9-tetrahydrocannabinol, the main Cannabis sativa (cannabis) component, induces anxiety and psychotic-like symptoms in healthy volunteers. These effects of Δ9-tetrahydrocannabinol are significantly reduced by cannabidiol (CBD), a cannabis constituent which is devoid of the typical effects of the plant.
This observation led us to suspect that CBD could have anxiolytic and/or antipsychotic actions. Studies in animal models and in healthy volunteers clearly suggest an anxiolytic-like effect of CBD. The antipsychotic-like properties of CBD have been investigated in animal models using behavioral and neurochemical techniques which suggested that CBD has a pharmacological profile similar to that of atypical antipsychotic drugs. The results of two studies on healthy volunteers using perception of binocular depth inversion and ketamine-induced psychotic symptoms supported the proposal of the antipsychotic-like properties of CBD. In addition, open case reports of schizophrenic patients treated with CBD and a preliminary report of a controlled clinical trial comparing CBD with an atypical antipsychotic drug have confirmed that this cannabinoid can be a safe and well-tolerated alternative treatment for schizophrenia.

Plant cannabinoids: a neglected pharmacological treasure trove
Raphael Mechoulam. British Journal of Pharmacology (2005) 146, 913–915
Cannabis sativa L. produces more than 60 terpeno-phenols that have not been detected in any other plant. One of these constituents, D9-tetrahydrocannabinol (THC) (Gaoni & Mechoulam, 1964) has been the object of thousands of publications, as it is by far the major psychoactive principle in marijuana and hashish. Cannabidiol (CBD), a nonpsychoactive component, has also been widely investigated due to its
anti-inflammatory, antischizophrenic and antiepileptic properties (Pertwee, 2005). Surprisingly, the other plant cannabinoids have been mostly neglected. Cannabinoid acids, which are precursors of the neutral cannabinoids, such as THC and
CBD, were shown to be antibiotic and were actually used for some time in veterinary medicine in Czechoslovakia about 50 years ago.

Endocannabinoids, cannabinoid receptors and inflammatory stress: an interview with Dr. Pál Pacher Helene F. Rosenberg1 Laboratory of Allergic Diseases, National Institute of Allergy and Infectious Disease, National Institutes of Health, Bethesda, Maryland, USA
Endocannabinoids are endogenous lipid mediators generated by virtually all cell types both in the brain and peripheral tissues, which exert broad range of biological effects (cardiovascular, psychoactive, antiinflammatory) similar to those of cannabis [1 ].
There are two major G protein-coupled cannabinoid receptors, CB1 and CB2 [2 , 3 ], Arachidonoyl ethanolamide or anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are the two most widely studied endocannabinoids which were isolated and characterized by the group of Raphael Mechoulam [5 , 6 ], who had earlier discovered the main psychoactive constituent of cannabis, delta-9-tetrahydrocannabinol [7 ].
Since these major groundbreaking discoveries, which were nicely described in a recent interview with Raphael Mechoulam in Addiction [9 ], it turned out that dysregulation of the endocannabinoid system may be implicated in virtually all diseases, and its pharmacological modulation holds tremendous promise in the treatment of various inflammatory, metabolic, and cardiovascular disorders, as well as pain and cancer [10 ].

Half-Baked Science: A Primer on Medicinal Cannabis Ryan Philippe
Cannabis (marijuana) is among the most widely used of all psychoactive drugs. Despite the fact that its possession and use is illegal in most countries, cannabis is used regularly by as many as 25 million people in North America and Europe
It is now known that cannabinoids act through receptors: CB1 receptors (cloned in 1990), and CB2 receptors (cloned in 1993) 9. Both of these receptor types are coupled through G proteins CB1 receptors are found in particularly high
concentrations within the central nervous system (CNS).CB1 receptor agonists are also analgesic, and in line with this property, there is evidence for the presence of CB1 receptors in several areas of the CNS that mediate the perception of pain.
CB2 receptors are expressed primarily by immune tissues, for example leukocytes, spleen and tonsils 9.
The discovery of cannabinoid receptors was followed in 1992 by the demonstration of the existence of endogenous cannabinoid receptor agonists. The most important of these are arachidonylethanolamide (anandamide) and 2-arachidonylglycerol (2-AG), and
there is evidence that both of these compounds can serve as neuromodulators or neurotransmitters.
Until the early twentieth century, cannabis was legal and found common use as an everyday medicine. In 1925, the Dangerous Drugs Act became law, and non-medicinal cannabis was made illegal in Britain. Canada followed suit and banned all forms of cannabis in 1927. Finally, in 1937, with 28 cannabis pharmaceuticals on the American market, the US government effectively criminalized cannabis by passing the Marihuana Tax Stamp Act .

The Emerging Role of the Endocannabinoid System in Endocrine Regulation and Energy Balance . Uberto Pagotto, Giovanni Marsicano, Daniela Cota, Beat Lutz and Renato Pasquali
In general, the endocannabinoid system is involved in many different physiological functions, many of which relate to stress-recovery systems and to the maintenance of homeostatic balance (10). Among other functions, the endocannabinoid system is involved in neuroprotection (11, 12, 13), modulation of nociception (14), regulation of motor activity (15), and the control of certain phases of memory processing (16, 17, 18). In addition, the endocannabinoid system is involved in modulating the immune and inflammatory responses (19, 20, 21). It also influences the cardiovascular and respiratory systems by controlling heart rate, blood pressure, and bronchial functions (22). Finally, yet importantly, endocannabinoids are known to exert important antiproliferative actions in tumor cells (23).

Pancreatic adenocarcinomas are among the most malignant forms of cancer.
The present study was undertaken to investigate the action of cannabinoids in pancreatic cancer. We show that cannabinoid receptors are expressed in human pancreatic tumor cell lines at much higher levels than in normal pancreatic tissue.
Studies conducted with Pancreatic Cancer cell lines showed that cannabinoid administration (a) induced apoptosis, (b) increased ceramide levels, and (c) up-regulated mRNA levels of the stress protein p8. These effects were prevented by blockade of the CB2 cannabinoid receptor. Cannabinoids also reduced the growth of tumor cells in two animal models of pancreatic cancer. In addition, cannabinoid treatment inhibited the spreading of pancreatic tumor cells. Moreover, cannabinoid administration selectively increased apoptosis and TRB3 expression in pancreatic tumor cells but not in normal tissue.
In conclusion, results presented here show that cannabinoids lead to apoptosis of pancreatic tumor cells via a CB2 receptor. These findings may contribute to set the basis for a new therapeutic approach for the treatment of pancreatic cancer.

CB1 Antagonist – Blocker
http://en.wikipedia.org/wiki/Rimonabant
Rimonabant (also known as SR141716, Acomplia, Bethin, Monaslim, Remonabent, Riobant, Slimona, Rimoslim, and Zimulti)[1] is an anorectic anti-obesity drug. It is an inverse agonist for the cannabinoid receptor CB1. Its main avenue of effect is reduction in appetite.
Rimonabant was the first selective CB1 receptor blocker to be approved for use anywhere in the world. In the UK, was available beginning in July 2006. As of 2008, the drug was available in 56 countries. On October 23, 2008, the European Medicines Agency (EMEA), Acomplia suspended from the UK market. Sanofi-Aventis suspended the drug.
Side-effects- Reports of severe depression are frequent. This is deemed to result from the drug’s being active in the central nervous system, an area of human physiology so complex that the effects of a drug are extremely difficult to predict or anticipate.[8]
Because the drug has the opposite effects of cannabinoid receptor agonists such as tetrahydrocannabinol (THC, one of the substances found in marijuana), which is neuroprotective against excitotoxicity,[9] it can be theorized that Rimonabant promotes the development of neurodegenerative diseases of the central nervous system such as Multiple sclerosis, Alzheimer’s disease, Amyotrophic lateral sclerosis (ALS), Parkinson’s disease, and Huntington’s disease in persons that are susceptible.[10] The reported development of previously clinically-silent multiple sclerosis in one patient taking Rimonabant suggests that any patients with an underlying neurological condition should not take Rimonabant, given the neuroprotective role of the endocannabinoid system in many experimental paradigms of neurological disease.
On June 15, 2007, BBC News reported [11] that a committee advising the U.S. FDA had voted not to recommend the drug’s approval because of concerns over suicidality, depression, and other related side-effects associated with use of the drug.

Cannabinoid Receptors and Endocannabinoids: Evidence for New Players

It is now well established that the psychoactive effects of Cannabis sativa are primarily mediated through neuronal CB1 receptors, while its therapeutic immune properties
are primarily mediated through CB2 receptors. Two endocannabinoids, arachidonoylethanolamide and 2-arachidonoylglycerol, have been identifi ed, their action on CB1 and CB2 thoroughly characterized, and their production
and inactivation elucidated. However, many significant exceptions to these rules exist.
Here we review the evidence suggesting that cannabinoids can modulate synaptic
transmission, the cardiovascular system, and the immune system through receptors distinct from CB1 and CB2, and that an additional “ independent ” endocannabinoid signaling system that involves palmitoylethanolamide may exist.
Arachidonoylethanolamide (AEA), also known as anandamide, was identifi ed in 1992 by Devane and colleagues and shown to bind with high affinity to CB1 receptors. 49

Cannabis’ Potential Exciting Researchers in Treatment of ALS, Parkinson’s Disease – URB597
Last Updated Friday, 15 June 2007 Giuffrida announced that a cannabinoid drug wards off Parkinson’s-like effects in mice. The disorder, which afflicts more than 1 million Americans, destroys neurons in a key part of the brain, causing patients
to lose control over movement. Giuffrida, with colleagues David Price and James Roberts, injected mice with a chemical called MPTP, which mimics
Parkinson’s damage. When some of the animals subsequently received a drug that blocks cannabinoid receptors, their nerve cells suffered far less damage than did the ells of the other mice. This was the first demonstration that a cannabinoid drug can have this effect. Although he is not sure how the anti-cannabinoid compound works, Giuffrida
suspects it protects neurons by reducing inflammation, a key component in Parkinson’s
DRUGS – FAAH
http://en.wikipedia.org/wiki/URB597
URB597 is a relatively selective inhibitor of the enzyme fatty acid amide hydrolase (FAAH).[1][2] FAAH is the primary degradatory enzyme for the endocannabinoid anandamide and, as such, inhibition of FAAH leads to an accumulation of anandamide in the CNS and periphery where it activates cannabinoid receptors. In pre-clinical laboratory tests researchers found URB597 increased the production of endocannabinoids resulting in measurable antidepressant and analgesic effects.[3]
URB597 is also known as KDS-4103. KDS-4103 is being developed by Kadmus Pharmaceuticals, Inc. for clinical trials in humans. Kadmus claims, on their website (linked below) that this class of compounds may have antidepressant, anti-anxiety, and pain-killing effects.

An alternative way of enhancing cannabinoid function might be to use drugs that interfere with the deactivation of the endocannabinoids, anandamide and 2-arachidonoylglycerol (2-AG) (15). We have recently described a class of such drugs, which act by blocking the intracellular hydrolysis of anandamide by fatty-acid amide hydrolase (FAAH) (16, 17).
Notably, however, URB597 elicits profound anxiolytic-like effects in rats,
which are prevented by the CB1 antagonist rimonabant
The addictive properties of Δ9-THC are a major obstacle to the development of cannabinoid-based therapeutics. Thus, it is particularly important that URB597 does not mimic the hedonic and interoceptives states evoked by direct-acting cannabinoid agonists.

http://www.rxwiki.com/index.php?title=Cannabinoids
Currently, there are three general types of cannabinoids: herbal cannabinoids occur uniquely in the cannabis plant; endogenous cannabinoids are produced in the bodies of humans and other animals; and synthetic cannabinoids are similar compounds produced in a laboratory.
The current understanding recognizes the role that endocannabinoids play in almost every major life function in the human body. Cannabinoids act as a bioregulatory mechanism for most life processes, which reveals why medical cannabis has been cited as treatments for many diseases and ailments in anecdotal reports and scientific literature. Some of these ailments include: pain, arthritic conditions, migraine headaches, anxiety, epileptic seizures, insomnia, loss of appetite, GERD (chronic heartburn), nausea, glaucoma, AIDS wasting syndrome, depression, bipolar disorder (particularly depression-manic-normal), multiple sclerosis, menstrual cramps, Parkinson’s, trigeminal neuralgia (tic douloureux), high blood pressure, irritable bowel syndrome, and bladder incontinence.

The Brain’s Own Marijuana by Roger A. Nicoll and Bradley N. Alger Scientific American, December 2004, pages 69-75.
The Lesson of Opium. The same question had arisen in the 1970s about morphine, a compound isolated from the poppy and found to bind to so-called opiate receptors in the brain. Scientists finally discovered that people make their own opioids–the enkephalins and endorphins. Morphine simply hijacks the receptors for the brain’s opioids.
It seemed likely that something similar was happening with THC and the cannabinoid receptor. In 1992, 28 years after he identified THC, Mechoulam discovered a small fatty acid produced in the brain that binds to CB1 and that mimics all the activities of marijuana. He named it anandamide, after the Sanskrit word ananda, “bliss.” Subsequently, Daniele Piomelli and Nephi Stella of the University of California at Irvine discovered that another lipid, 2-arachidonoyl glycerol (2-AG), is even more abundant in certain brain regions than anandamide is. Together the two compounds are considered the major endogenous cannabinoids, or endocannabinoids.
The results indicate that endocannabinoids are important in extinguishing the bad feelings and pain triggered by reminders of past experiences. The discoveries raise the possibility that abnormally low numbers of cannabinoid receptors or the faulty release of
endogenous cannabinoids are involved in post-traumatic stress syndrome, phobias and certain forms of chronic pain. This suggestion fits with the fact that some people smoke marijuana to decrease their anxiety.

Cannabinoids Inhibit the Vascular Endothelial Growth Factor Pathway in Gliomas
Manuel Guzmán et al., Spain
Cannabinoids inhibit tumor angiogenesis in mice, but the mechanism of their antiangiogenic action is still unknown. Because the vascular endothelial growth factor (VEGF) pathway plays a critical role in tumor angiogenesis, here we studied whether cannabinoids affect it. As a first approach, cDNA array analysis showed that cannabinoid administration to mice bearing s.c. gliomas lowered the expression of various VEGF pathway-related genes. The use of other methods (ELISA, Western blotting, and confocal microscopy) provided additional evidence that cannabinoids depressed the VEGF pathway by decreasing the production of VEGF and the activation of VEGF receptor (VEGFR)-2, the most prominent VEGF receptor, in cultured glioma cells and in mouse gliomas. Cannabinoid-induced inhibition of VEGF production and VEGFR-2 activation was abrogated both in vitro and in vivo by pharmacological blockade of ceramide biosynthesis. These changes in the VEGF pathway were paralleled by changes in tumor size. Moreover, intratumoral administration of the cannabinoid 9-tetrahydrocannabinol to two patients with glioblastoma multiforme (grade IV astrocytoma) decreased VEGF levels and VEGFR-2 activation in the tumors. Because blockade of the VEGF pathway constitutes one of the most promising antitumoral approaches currently available, the present findings provide a novel pharmacological target for cannabinoid-based therapies.

Cannabinoid Receptor Activation Induces Apoptosis through Tumor Necrosis Factor –Mediated Ceramide De novo Synthesis in Colon Cancer Cells. Fabio Cianchi et al, Italy
Results: We show that the CB1 receptor was mainly expressed in human normal colonic epithelium whereas tumor tissue was strongly positive for the CB2 receptor. The activation of the CB1 and, more efficiently, of the CB2 receptors induced apoptosis and increased ceramide levels in the DLD-1 and HT29 cells. Apoptosis was prevented by the pharmacologic inhibition of ceramide de novo synthesis. The CB2 agonist CB13 also reduced the growth of DLD-1 cells in a mouse model of colon cancer. The knockdown of TNF- mRNA abrogated the ceramide increase and, therefore, the apoptotic effect induced by cannabinoid receptor activation.
Conclusions: The present study shows that either CB1 or CB2 receptor activation induces apoptosis through ceramide de novo synthesis in colon cancer cells. Our data unveiled, for the first time, that TNF- acts as a link between cannabinoid receptor activation and ceramide production.

Marinol vs. Marijuana: Politics, Science, and Popular Culture Kambiz. Akhavan
Having extensively analyzed the Marinol versus marijuana debate from a popular culture perspective, and within a historical and theoretical context, it is now apparent just how differently America treats two essentially similar substances.
Marinol enjoys cultural and medical legitimacy from society, as well as tax breaks and open market privileges from the government. Marijuana users still risk incarceration and social marginalization, while simultaneously suffering from debilitating illnesses. Despite the wealth of scientific information and the bevy of organizational support illustrating marijuana’s numerous medical benefits, the federal government chooses to validate the inferior Marinol medication, and to continue its war on drugs and drug users. Considering America’s history of vilifying marijuana, and given the American penchant to promote pharmaceuticals over all other medicines, the current drug policy should not shock us, but it should disappoint us.
In 1999, Marinol was rescheduled from Schedule II to III of the Controlled Substances Act, reflecting a finding that THC had a potential for abuse less than that of cocaine, and heroin. This rescheduling comprised part of the argument for a 2002 petition for removal of cannabis from Schedule I of the Controlled Substances Act,
in which petitioner Jon Gettman noted, “Cannabis is a natural source of dronabinol (THC), the ingredient of Marinol, a Schedule III drug. There are no grounds to schedule cannabis in a more restrictive schedule than Marinol”[57].

The New Science of Cannabinoid-Based Medicine:
An Interview with Dr. Raphael Mechoulam By David Jay Brown
http://en.wikipedia.org/wiki/Raphael_Mechoulam
Raphael Mechoulam, while junior member at the Weizmann Institute of Science, isolated and synthesised THC Δ9-tetrahydrocannabinol, the first described endocannabinoid anandamide was isolated by two of his postdoctoral researchers, Lumír Hanuš and William Devane. Another endogenous cannabinoid, 2-AG, was soon discovered by Shimon Ben-Shabat, one of his PhD students.
http://www.endocannabinoid.net/Mechoulam.aspx
The three major illicit drugs derived from plants were then, and still are, opium, coca and cannabis. Morphine had been isolated from opium early in the 19th century and its very complicated structure was elucidated in the 1920s by Sir Robert Robinson. Cocaine was isolated from coca leaves in the middle of the 19th century and the famous chemist Richard Willstatter had been able to describe its unusual structure in the last decade of the 19th century. I believe that the cannabinoids represent a medicinal treasure trove which waits to be discovered.

Cannabinoids as Therapeutics by Raphael Mechoulam
Cannabinoids as Therapeutics covers the use of Cannabis in India, and is an expression of thanks to the herbal practitioners who have carried on the drug’s medical traditions through the centuries. Cannabinoids as Therapeutics describes the progression from the time when Cannabis was used by ancient medical practitioners as a herbal remedy to the present day, when we are approaching an understanding of the endocannabinoid system and the role that cannabinoids may pay in medicine.
To quote Mechoulam, “We are learning a lot almost every week. I am almost certain that various cannabinoids will become important drugs. Almost all major pharmaceutical companies have groups working on cannabinoids.” Regardless of the chemicals’ rocky past, it seems researchers are at a point of no return. In the past 200 years cannabinoids have ricocheted in the public mind between being a miracle cure and an obsession of the dissolute. Now we’ve gained basic knowledge of what cannabinoids are, how they work, and how to synthesize them. We are at the same time knowledgeable and naive, cracking the chemical code while the applications remain elusive—and sometimes forbidden. The next decade should be especially exciting for anyone in this field.

April 4, 2008 – Before speaking to the 5th Clinical Conference on Cannabis Therapeutics in Pacific Grove, CA, Deputy Director of NORML Paul Armentano talks about new science on Cannabis (marijuana) and the Endo-Cannabinoid system being done in Europe, while American cancer patients, many with tragic cases of Glioma brain tumors, seek any news of an alternative therapy.
Paul references the work of Dr. Manuel Guzman, Madrid, who has seen THC kill brain cancer cells while leaving surrounding tissue unharmed, demonstating the neuroprotectant properties of Cannabinoids. Then Paul is joined by Dr. David Bearman, of Galeta, CA, who tells of the fear that patients feel when encountering an cancer like Glioma. Paul has collected the latest research on medical Cannabis, available in a PDF or booklet at: http://norml.org/
We also talk about Cannabis in the treatment of ALS (Lou Gehrig’s Disease) and the documentary I’m doing on Cathy Jordan, a medical marijuana patient who has survived ALS for 22 years now! View “Surviving ALS” in chapter releases:

Lester Grinspoon
http://en.wikipedia.org/wiki/Lester_Grinspoon
Lester Grinspoon is Associate Professor Emeritus of Psychiatry at Harvard Medical School and the author of several drug-related books, including Marijuana Reconsidered, Psychedelic Drugs Reconsidered, and Marijuana: The Forbidden Medicine. The first two were published during the 1970s, when it appeared cannabis was well on its way to nationwide decriminalization in the United States. The latter was published in 1993. It describes a variety of ailments for which cannabis ingestion may be indicated.
http://www.abc.net.au/quantum/poison/marijuan/lester.htm
Interview with Lester Grinspoon 1997
My conclusion was that the most harmful thing about marijuana was the fact that more than 400,000 people a year were being arrested. Firstly, the US Government is too embarrassed to acknowledge that it’s been wrong about marijuana, and that the 10 million people arrested since 1967 were arrested for nothing. Marijuana is remarkably non toxic. In all the years that marijuana has been used, there’s not been one single documented death from it. I don’t know that you can say the same thing about any other drug.

Puffing is The Best Medicine By Lester Grinspoon M.D.
Los Angeles Times – May 5, 2006.
Los Angeles — The Food And Drug Administration is contradicting itself.] It recently reiterated its position that cannabis has no medical utility, but it also approved advanced clinical trials for a marijuana-derived drug called Sativex, a liquid preparation of two of the most therapeutically useful compounds of cannabis. This is the same agency that in 1985 approved Marinol, another oral cannabis-derived medicine.
I have yet to see a patient who preferred Marinol to smoked marijuana. Similarly, the commercial success of Sativex will largely depend on how vigorously the marijuana laws are enforced. It is not unreasonable to believe that drug companies have an interest in sustaining the prohibition against the herb.

Advances in cannabis research have paralleled developments in opioid pharmacology whereby a psychoactive plant extract has elucidated novel endogenous signalling systems with therapeutic significance. Cannabinoids (CBs) are chemical compounds derived from cannabis. The major psychotropic CB delta-9-tetrahydrocannabinol (9-THC) was isolated in 1964 and the first CB receptor (CB1R) was cloned in 1990. CB signalling occurs via G-protein-coupled receptors distributed throughout the body. Endocannabinoids are derivatives of arachidonic acid that function in diverse physiological systems. Neuronal CB1Rs modulate synaptic transmission and mediate psychoactivity. Immune-cell CB2 receptors (CB2R) may down-regulate neuroinflammation and influence cyclooxygenase-dependent pathways.

Marijuana research hampered by access from government and politics, scientists say By Ariana Eunjung Cha, Published: March 21,2014 Washington Post
All in all, a typical day. We saw 24 patients over the course of nine and a half hours (approximately 24 minutes per patient). Eighteen were male, 6 were female. Thirteen were new patients and there were 11 renewals. The average age was 41.7 years and the most common diagnosis was chronic pain (14 of 24). As usual there were a wide variety of other diagnoses including Lymphoma, Tourette’s, PTSD, Myesthenia Gravis, Parkinson’s Disease, Heroin addiction, Fibromyalgia and panic disorder.
