The Pharmacokinetics, Efficacy, Safety, and Ease of Use of a Novel Portable Metered-Dose Cannabis Inhaler in Patients With Chronic Neuropathic Pain: A Phase 1a Study.

“Chronic neuropathic pain is often refractory to standard pharmacological treatments.

Although growing evidence supports the use of inhaled cannabis for neuropathic pain, the lack of standard inhaled dosing plays a major obstacle in cannabis becoming a “main stream” pharmacological treatment for neuropathic pain.

The objective of this study was to explore the pharmacokinetics, safety, tolerability, efficacy, and ease of use of a novel portable thermal-metered-dose inhaler (tMDI) for cannabis in a cohort of eight patients suffering from chronic neuropathic pain and on a stable analgesic regimen including medicinal cannabis…

This trial suggests the potential use of the Syqe Inhaler device as a smokeless delivery system of medicinal cannabis, producing a Δ9-THC pharmacokinetic profile with low interindividual variation of Cmax, achieving pharmaceutical standards for inhaled drugs.”

Medical Marijuana Helps Cure Chronic Disease

Medical Marijuana Helps Cure Chronic Disease

“The medicinal power of Marijuana is well documented throughtout history

Back in 2700 BC, According to Chinese lore, the Emperor Shen Nung, considered the Father of Chinese medicine, in 2700 BC ,discovered the healing properties of Marijuana as well as Ginseng and Ephedra.

Throughout recorded history, the use of Medical Marijuana  has been linked to the ancient Egyptians, Persians, Greek civilizations, George Washington, Queen Victoria and even mainstream medicine by the 1840s.

From the 1850s to Y 1942, Marijuana was listed in the United States Pharmacopeia, an official public standards-setting authority for all prescription and over-the counter medicines, as a treatment for tetanus, cholera, rabies, dysentery, alcoholism, opiate addiction, convulsive disorders, insanity, excessive menstrual bleeding and many other health problems. My father was a Dental doctor and had a license to dispense the drug, pharmacies carried it back then.

During that same time frame prohibition gained popularity, that along with a growing “faith” in federal government.

By Y 1937, the United States passed its 1st federal law against Marijuana despite objections by the American Medical Association (AMA).

In fact, Dr. William C. Woodward, testifying on behalf of the AMA, told the US Congress:

“The American Medical Association knows of no evidence that Marijuana is a dangerous drug.”

He warned that a prohibition “loses sight of the fact that future investigation may show that there are substantial medical uses for Cannabis.”

Today, we see a growing trend of acceptance of Marijuana for its medicinal purposes.

Dr. Sanjay Gupta, CNN’s chief medical correspondent, reversed his Y 2009 opinion against Marijuana when he said, “We have been terribly and systematically misled for nearly 70 yrs in the United States, and I apologize for my own role in that.”

Now people including lawmakers are seeing the legalization of Marijuana in states like Colorado and Washington for “recreational” purposes. Most Americans are in favor of Medical Marijuana,  and the legalization of this drug.

The Big Q: why does the federal government want to ban its usage?

The Big A: it is all about control and money, and there is a major market for it, plus it poses a major threat to the pharmaceutical industry.

Below are just a few of the many health benefits associated with Medical Marijuana:

1. It can stop HIV from spreading throughout the body.
2. It slows the progression of Alzheimer’s.
3. It slows the spread of cancer cells.
4. It is an active pain reliever.
5. It can prevent or help with opiate addiction.
6. It combats depression, anxiety and ADHD.
7. It can treat epilepsy and Tourette’s.
8. It can help with other neurological damage, such as concussions and strokes.
9. It can prevent blindness from glaucoma.
10. Its connected to lower insulin levels in diabetics.

Contrary to popular notions, many patients  experience health benefits from Medical Marijuana without “getting stoned.””

Immunoactive effects of cannabinoids: considerations for the therapeutic use of cannabinoid receptor agonists and antagonists

Figure 1

“The active constituents of Cannabis sativa have been used for centuries as recreational drugs and medicinal agents. Today, marijuana is the most prevalent drug of abuse in the United States and, conversely, therapeutic use of marijuana constituents are gaining mainstream clinical and political acceptance.

Given the documented contributions of endocannabinoid signaling to a range of physiological systems, including cognitive function, and the control of eating behaviors, it is unsurprising that cannabinoid receptor agonists and antagonists are showing significant clinical potential.

In addition to the neuroactive effects of cannabinoids, an emerging body of data suggests that both endogenous and exogenous cannabinoids are potently immunoactive.

The central premise of this review article is that the immunological effects of cannabinoids should be considered in the context of each prescribing decision.

We present evidence that the immunological effects of cannabinoid receptor agonists and antagonists are highly relevant to the spectrum of disorders for which cannabinoid therapeutics are currently offered.

Therapeutically relevant cannabinoid receptor ligands include tetra-hydrocannabinol itself, its synthetic forms, and its closely related compounds.

As a final point, the application of CB1 antagonists may be immunostimulative…”

CB2 cannabinoid receptor agonist, JWH-015, triggers apoptosis in immune cells: potential role for CB2-selective ligands as immunosuppressive agents.

“Marijuana has been used for recreational and medicinal purposes for centuries. Its medicinal use can be traced back to ancient Chinese and Egyptian civilizations…

Cannabinoids are known to interact with CB1 and CB2 receptors expressed in the nervous and immune system, respectively, and mediate a wide range of effects, including anti-inflammatory properties…

The current study suggests that targeting CB2 receptors may constitute a unique treatment modality against inflammatory diseases…

Together, this study suggests that CB2-selective agonists, devoid of psychotropic effect, may serve as novel anti-inflammatory/immunosuppressive agents.”

Cannabinoid-induced apoptosis in immune cells as a pathway to immunosuppression.

Fig. 1

“Cannabinoids are a group of compounds found in the marijuana plant (Cannabis sativaL.). Marijuana has been used both for recreational and medicinal purposes for several centuries.

Cannabinoids have been shown to be effective in the treatment of nausea and vomiting associated with cancer chemotherapy, anorexia and cachexia seen in HIV/AIDS patients, as well as neuropathic pain, and spasticity in multiple sclerosis.

More recently, the anti-inflammatory properties of cannabinoids are drawing significant attention. In the last 15 years, studies with marijuana cannabinoids led to the discovery of cannabinoid receptors (CB1 and CB2) and their endogenous ligands, which make up what is known as the endocannabinoid system.

Cannabinoids are a group of compounds present in Cannabis plant (Cannabis sativa L.). They mediate their physiological and behavioral effects by activating specific cannabinoid receptors. With the recent discovery of the cannabinoid receptors (CB1 and CB2) and the endocannabinoid system, research in this field has expanded exponentially.

Cannabinoids have been shown to act as potent immunosuppressive and anti-inflammatory agents and have been shown to mediate beneficial effects in a wide range of immune-mediated diseases such as multiple sclerosis, diabetes, septic shock, rheumatoid arthritis, and allergic asthma.

Cannabinoid receptor 1 (CB1) is mainly expressed on the cells of the central nervous system as well as in the periphery. In contrast, cannabinoid receptor 2 (CB2) is predominantly expressed on immune cells. The precise mechanisms through which cannabinoids mediate immunosuppression is only now beginning to be understood…

In this review, we will focus on apoptotic mechanisms of immunosuppression mediated by cannabinoids on different immune cell populations and discuss how activation of CB2 provides a novel therapeutic modality against inflammatory and autoimmune diseases as well as malignancies of the immune system, without exerting the untoward psychotropic effects…

…cannabinoids do induce apoptosis in immune cells, alleviating inflammatory responses and protecting the host from acute and chronic inflammation.

The cumulative effect of cannabinoids on all cell populations of the immune system can be beneficial, when there is a need for immune suppression.

For example, in patients with autoimmune diseases such as multiple sclerosis, arthritis and lupus, or in those with septic shock, where the disease is caused by activated immune cells, targeting the immune cells via CB2 agonists may trigger apoptosis and act as anti-inflammatory therapy.

CB2 select agonists are not psychoactive and because CB2 is expressed primarily in immune cells, use of CB2 agonists could provide a novel therapeutic modality against autoimmune and inflammatory diseases.

In addition to the use of exogenous cannabinoids, in vivo manipulation of endocannabinoids may also offer novel treatment opportunities against cancer and autoimmune diseases.”

Direct suppression of autoreactive lymphocytes in the central nervous system via the CB2 receptor.

The cannabinoid system is evolutionally conserved and is present in invertebrates and vertebrates. One of the best-studied cannabinoids is Δ9-tetrahydrocannabinol (THC), the predominant active component of Cannabis sativa or marijuana.

The marijuana plant has been exploited by humans since their early history and was used for centuries in Asian medicine to reduce the severity of pain, inflammation and asthma. However, only recently have the mechanisms of the medicinal properties of THC begun to be understood. This understanding is largely due to the identification and cloning of two cannabinoid receptors.

The cannabinoid system is now recognized as a regulator of both the nervous and immune systems.

Although marijuana has been used for centuries for the treatment of a variety of disorders, its therapeutic mechanisms are only now being understood.

The best-studied plant cannabinoid, delta9-tetrahydrocannabinol (THC), produced by Cannabis sativa and found in marijuana, has shown evidence of being immunosuppressive in both in vivo and in vitro.

These studies are theoretically in agreement with the suggestions of others that cannabinoid receptor agonists would be beneficial for the treatment of MS in humans.”

Marijuana Effectively Reduces Seizures in Epilepsy Patients

marijuanas

“Medicinal uses of marijuana have been a matter for heated debate for quite some time now. A review by American Academy of neurology collated all available information on marijuana use for brain disease treatment and concluded that except for treating symptoms of multiple sclerosis, there is no hard evidence in favor of medical usage of marijuana.

But now some articles have been published in the journal Epilepsia that contradicts the earlier review. One of these articles is a case study of a family living in Denver, CO. The child in the family suffers from a severe form of epilepsy known as Dravet Syndrome and used to have frequent seizures, as many as 50 convulsions a day. But the child was given “Charlotte’s Web”- a marijuana strain with high levels of cannabidiol (CBD) and tetrahydrocannabinol (THC). Reportedly, the seizures decreased considerably and now the child suffers from only 2 or 3 seizures each month.

According to the author of the article, Dr. Edward Maa, “As medical professionals it is important that we further the evidence of whether CBD in cannabis is an effective antiepileptic therapy.””

Getting High on the Endocannabinoid System

“The endogenous cannabinoid system—named for the plant that led to its discovery—is one of the most important physiologic systems involved in establishing and maintaining human health.

Endocannabinoids and their receptors are found throughout the body: in the brain, organs, connective tissues, glands, and immune cells. With its complex actions in our immune system, nervous system, and virtually all of the body’s organs, the endocannabinoids are literally a bridge between body and mind.

By understanding this system, we begin to see a mechanism that could connect brain activity and states of physical health and disease.

…either stimulating or inhibiting the endocannabinoid system could have beneficial effects.

The most direct route of THC administration is by smoking marijuana or other forms of cannabis. Yet purified, FDA-approved medicinal preparations of THC are available in pill form… Why not just take a pill? There are several reasons that some patients prefer puffing over swallowing. One quantitatively minor factor is potential lethality.

It is possible to get a fatal overdose by swallowing too many THC pills at once, whereas documented evidence of death simply from smoking too much cannabis does not seem to exist.”

The draft genome and transcriptome of Cannabis sativa

“Cannabis sativa has been cultivated throughout human history as a source of fiber, oil and food, and for its medicinal and intoxicating properties.

The availability of the Cannabis sativa genome enables the study of a multifunctional plant that occupies a unique role in human culture. Its availability will aid the development of therapeutic marijuana strains with tailored cannabinoid profiles and provide a basis for the breeding of hemp with improved agronomic characteristics.”

Pro-resolution, protective and anti-nociceptive effects of a cannabis extract in the rat gastrointestinal tract.

“Cannabis is widely used for treating a number of gastrointestinal ailments…

In the present study, we tested the effects (in rats) of a simple extract of medicinal cannabis (called “MFF”) for its ability to promote resolution of colitis…

These results demonstrate that a simple extract of medicinal cannabis can significantly enhance resolution of inflammation and injury, as well as prevent injury, in the gastrointestinal tract. Interestingly, different cannabinoid receptors were involved in some of the effects. MFF may serve as the basis for a simple preparation of cannabis that would produce beneficial effects in the GI tract with reduced systemic toxicity.”
