Pot patch considered medical breakthrough

“Advocates are fighting to legalize marijuana. The University of Mississippi has the only legally grown marijuana crop in the nation.Faculty members and student researchers have now developed a new patch that could potentially provide help to patients who need it.

The patch developed at Ole Miss could help patients overcome problems associated with taking the drug in pill form. The patch is placed above the gum line.

“In addition to pain, it will include things like reducing intraocular pressure and therefore would be good for glaucoma. [It] will be good for alleviating the nausea and vomiting associated with chemotherapy; it would also be good for appetite stimulation for patients suffering from the syndrome, anti-inflammatory activity, anti-anxiety,” explains Dr. ElSohly.”

The pharmacologic and clinical effects of medical cannabis.

“Cannabis, or marijuana, has been used for medicinal purposes for many years. Several types of cannabinoid medicines are available in the United States and Canada. Dronabinol (schedule III), nabilone (schedule II), and nabiximols (not U.S. Food and Drug Administration approved) are cannabis-derived pharmaceuticals.

Medical cannabis or medical marijuana, a leafy plant cultivated for the production of its leaves and flowering tops, is a schedule I drug, but patients obtain it through cannabis dispensaries and statewide programs. The effect that cannabinoid compounds have on the cannabinoid receptors (CB(1) and CB(2) ) found in the brain can create varying pharmacologic responses based on formulation and patient characteristics. The cannabinoid Δ(9) -tetrahydrocannabinol has been determined to have the primary psychoactive effects; the effects of several other key cannabinoid compounds have yet to be fully elucidated. Dronabinol and nabilone are indicated for the treatment of nausea and vomiting associated with cancer chemotherapy and of anorexia associated with weight loss in patients with acquired immune deficiency syndrome. However, pain and muscle spasms are the most common reasons that medical cannabis is being recommended.

Studies of medical cannabis show significant improvement in various types of pain and muscle spasticity. Reported adverse effects are typically not serious, with the most common being dizziness. Safety concerns regarding cannabis include the increased risk of developing schizophrenia with adolescent use, impairments in memory and cognition, accidental pediatric ingestions, and lack of safety packaging for medical cannabis formulations. This article will describe the pharmacology of cannabis, effects of various dosage formulations, therapeutics benefits and risks of cannabis for pain and muscle spasm, and safety concerns of medical cannabis use.”

Medical Marijuana Is Safe for Children

“Numerous cases show clinical cannabis is effective on illnesses in children”

By  William Courtney, M.D. is CEO of Cannabis International.

“The courage and fortitude of parents who have chosen cannabis compounds to treat their children facing life-threatening illness have raised eyebrows. Some live in terror that their government will take their child away, since medical marijuana is only legal in some states. However, there are numerous cases demonstrating the benefits of clinical cannabis, which happen to threaten a very profitable healthcare industry that relies on conventional drugs, as well as political agendas.

The cannabinoid acids in cannabis have been found to have anti-proliferative, anti-neoplastic, anti-inflammatory, anti-epileptic, anti-ischemic, anti-diabetic, anti-psychotic, anti-nausea, anti-spasmodic, antibiotic, anti-anxiety, and anti-depressant functions. The anti-neoplastic action of cannabis—inhibiting development of malignant cells—was recognized in the 1970s and patented by the U.S. Department of Health and Human Services in 2003.

Out of 7,000 patients, my youngest, an 8-month-old, was diagnosed with a massive midbrain tumor. Pediatric oncologists recommended chemotherapy and radiation. Instead, the parents applied a cannabinoid concentrate to their son’s pacifier twice a day, which resulted in a significant reduction in the size of the tumor in 30 days. The response prevented a million-dollar chemo-radiation hospitalization. The child’s oncologist calls the infant a ‘miracle baby,’ but most medical experts would discount the case as anecdotal, unacceptable in a peer-reviewed journal. But the real peers are other parents reluctant to consent to the devastation of surgery, chemotherapy, and radiation—not those benefiting from the $2.6 trillion healthcare industry.

A 2-year-old spent a year in a pediatric oncology ward, endured 39 hours of brain surgery, received chemotherapy, a bone marrow transplant, and radiation under general anesthesia for 42 days, only to be discharged home on hospice and morphine. The child’s local pediatrician started to treat her with juiced raw cannabis leaf. Two years later, she is still alive, now free of cancer and scar tissue.

A 6-year-old patient with a severe, intractable form of childhood epilepsy, was tried on 11 anti-epileptics, including experimental European drugs. He was finally placed on a drug commonly used to prevent seizures, but continued having 300-400 seizures a day. An ointment produced from cannabis with an increased amount of cannabidiol, a compound patented by HHS, has reduced his seizures to one every 3-4 days.

Several years ago, I proposed that cannabis be recognized as an essential nutrient in the diet of individuals in their 30s and older. Children were excluded out of fear of backlash but it is now my incontrovertible opinion that the immune system of the 8-month-old would never have allowed the tumor to gain a foothold if supported with dietary cannabis, or Vitamin F.

We know Vitamin C deficiency results in scurvy and Vitamin D deficiency results in rickets. Vitamin F, the previous label for Omega-3 and -6 essential fatty acids, is an appropriate appellation for the cannabinoid acids found in cannabis. Vitamin F deficiency allows the cell proliferation found in tumors and cancer. Three studies of over 24,000 children have shown no adverse effects from use of cannabis in pregnancy.

There is no other area in medicine where the heavy hand of federal funding and political agenda compromise valid and reproducible findings to this extent. To advance disease prevention and benign therapy, we must re-examine our preconceptions.”

The endocannabinoid nervous system: unique opportunities for therapeutic intervention.

“The active principle in marijuana, Delta(9)-tetrahydrocannabinol (THC), has been shown to have wide therapeutic application for a number of important medical conditions, including pain, anxiety, glaucoma, nausea, emesis, muscle spasms, and wasting diseases. Delta(9)-THC binds to and activates two known cannabinoid receptors found in mammalian tissue, CB1 and CB2. The development of cannabinoid-based therapeutics has focused predominantly on the CB1 receptor, based on its predominant and abundant localization in the CNS.

Like most of the known cannabinoid agonists, Delta(9)-THC is lipophilic and relatively nonselective for both receptor subtypes.

Clinical studies show that nonselective cannabinoid agonists are relatively safe and provide therapeutic efficacy, but that they also induce psychotropic side effects. Recent studies of the biosynthesis, release, transport, and disposition of anandamide are beginning to provide an understanding of the role of lipid transmitters in the CNS. This review attempts to link current understanding of the basic biology of the endocannabinoid nervous system to novel opportunities for therapeutic intervention.

This new knowledge may facilitate the development of cannabinoid receptor-targeted therapeutics with improved safety and efficacy profiles.”

Cannabidiol: an overview of some pharmacological aspects.

“Over the past few years, considerable attention has focused on cannabidiol (CBD), a major nonpsychotropic constituent of cannabis.

The authors present a review on the chemistry of CBD and discuss the anticonvulsive, antianxiety, antipsychotic, antinausea, and antirheumatoid arthritic properties of CBD.

CBD does not bind to the known cannabinoid receptors, and its mechanism of action is yet unknown. It is possible that, in part at least, its effects are due to its recently discovered inhibition of anandamide uptake and hydrolysis and to its antioxidative effect.”

Cannabidiol: an overview of some chemical and pharmacological aspects. Part I: chemical aspects.

“Over the last few years considerable attention has focused on cannabidiol (CBD), a major non-psychotropic constituent of Cannabis. In Part I of this review we present a condensed survey of the chemistry of CBD; in Part II, to be published later, we shall discuss the anti-convulsive, anti-anxiety, anti-psychotic, anti-nausea and anti-rheumatoid arthritic properties of CBD. CBD does not bind to the known cannabinoid receptors and its mechanism of action is yet unknown. In Part II we shall also present evidence that it is conceivable that, in part at least, its effects are due to its recently discovered inhibition of anandamide uptake and hydrolysis and to its anti-oxidative effect.”

The development of cannabinoid CBII receptor agonists for the treatment of central neuropathies.

“Cannabinoids have been used in the treatment of nausea and emesis, anorexia and cachexia, tremor and pain associated with multiple sclerosis. These treatments are limited by the psychoactive side-effects of CBI activation. Recently CBII has been described within the CNS, both in microglia and neuronal progenitor cells (NPCs), but with few exceptions, not by neurons within the CNS.

This has suggested that CBII agonists could have potential to treat various conditions without psycho-activity.

This article reviews the potential for CBII agonists as treatments for neurological conditions, with a focus on microglia and NPCs as drug targets. We first discuss the role of microglia in the healthy brain, and then the role of microglia in chronic neuroinflammatory disorders, including Alzheimer’s disease and Parkinson’s disease, as well as in neuroinflammation following acute brain injury such as stroke and global hypoxia. As activation of CBII receptor on microglia results in suppression of the proliferation and activation of microglia, there is potential for the anti-inflammatory properties of CBII agonist to treat neuropathologies that involve heightened microglia activity. In addition, activating CBII receptors may result in an increase in proliferation and affect migration of NPCs.Therefore, it is possible that CBII agonists may assist in the treatment of neuropathologies by increasing neurogenesis…”

Medical Marijuana Use: Miracle Medicine Good for Dozens of Diseases

“When the State of Oregon first legalized Medical Marijuana I disbelieved and was astonished at the diverse medical conditions that State DHS said were acceptable conditions for a permit to use: Cancer, Glaucoma, HIV/AIDS, Alzheimer’s, Cachexia/Anorexia, Severe pain, Severe nausea, Seizures and Muscle spasms.

I found out soon after I started seeing patients for marijuana permits that the DHS was far too modest about this surprisingly effective medicine. As I continued to see more than 4000 patients I was truly amazed at the diversity of diseases for which marijuana was helpful and more so than standard medicine.”-

From cannabis to the endocannabinoid system: refocussing attention on potential clinical benefits.

Image result for West Indian Med J

“Cannabis sativa is one of the oldest herbal remedies known to man. Over the past four thousand years, it has been used for the treatment of numerous diseases but due to its psychoactive properties, its current medicinal usage is highly restricted. In this review, we seek to highlight advances made over the last forty years in the understanding of the mechanisms responsible for the effects of cannabis on the human body and how these can potentially be utilized in clinical practice. During this time, the primary active ingredients in cannabis have been isolated, specific cannabinoid receptors have been discovered and at least five endogenous cannabinoid neurotransmitters (endocannabinoids) have been identified. Together, these form the framework of a complex endocannabinoid signalling system that has widespread distribution in the body and plays a role in regulating numerous physiological processes within the body. Cannabinoid ligands are therefore thought to display considerable therapeutic potential and the drive to develop compounds that can be targeted to specific neuronal systems at low enough doses so as to eliminate cognitive side effects remains the ‘holy grail’ of endocannabinoid research.”

Naturally occurring and related synthetic cannabinoids and their potential therapeutic applications.

Abstract

“Naturally occurring cannabinoids (phytocannabinoids) are biosynthetically related terpenophenolic compounds uniquely produced by the highly variable plant, Cannabis sativa L. Natural and synthetic cannabinoids have been extensively studied since the discovery that the psychotropic effects of cannabis are mainly due to Delta(9)-THC. However, cannabinoids exert pharmacological actions on other biological systems such as the cardiovascular, immune and endocrine systems. Most of these effects have been attributed to the ability of these compounds to interact with the cannabinoid CB1 and CB2 receptors. The FDA approval of Marinol, a product containing synthetic Delta(9)-THC (dronabinol), in 1985 for the control of nausea and vomiting in cancer patients receiving chemotherapy, and in 1992 as an appetite stimulant for AIDS patients, has further intensified the research interest in these compounds. This article reviews patents (2003-2007) that describe methods for isolation of cannabinoids from cannabis, chemical and chromatographic methods for their purification, synthesis, and potential therapeutic applications of these compounds.”
