“Little is known about cannabis use in hunter-gatherers. Therefore, we investigated cannabis use in the Aka, a population of foragers of the Congo Basin.

Because cannabis contains anthelminthic compounds,” http://medical-dictionary.thefreedictionary.com/anthelmintic ” and the Aka have a high prevalence of helminthiasis, we also tested the hypothesis that cannabis use might be an unconscious form of self-medication against helminths.

THCA levels were negatively correlated with parasite infection and reinfection, supporting the self-medication hypothesis.

This, to our knowledge, is the first biomarker-validated study of cannabis use in a hunting-gathering population, and also the first to explore the relationship between the use of cannabis, which is toxic to helminths, and intestinal helminth infection.

Although the conventional view is that drug abuse impairs immunity, thus increasing susceptibility to infection, if recreational drug use is explained by the drugs’ antiparasitic properties, this would suggest that the immune system plays a key role in regulating drug use.”

“Medical Marijuana Smoking Linked to Parasite Prevention. Scientists from Washington State University have suggested that smoking cannabis may have a beneficial effect with regard to the avoidance of intestinal parasite infections, which could explain why the drug has such a long history of recreational use… those who smoked cannabis had a lower rate of infection.” http://www.newhistorian.com/medical-marijuana-smoking-linked-to-parasite-prevention/3936/

[Cannabinoids in medicine].

Posted on May 18, 2015 by David

“Cannabinoids have been known for many centuries because of their various effects in healthcare. They are primarily effective in reducing nausea, vomiting, pain, anorexia, spasticity and depression. Some other effects are known, all seem to be mediated by cannabinoid receptors in the central nervous system. In the past years, medical use has been proven in several studies. Today, the therapeutical use of cannabinoids in medicine is increasing, and access was made easier. Especially in pain-management and palliative care, they seem to be a valuable therapeutic option.”

A novel hemp seed meal protein hydrolysate reduces oxidative stress factors in spontaneously hypertensive rats.

Posted on May 10, 2015 by David

“This report shows the antioxidant effects of a hemp seed meal protein hydrolysate (HMH) in spontaneously hypertensive rats (SHR)…

The results suggest that HMH contained antioxidant peptides that reduced the rate of lipid peroxidation in SHRs with enhanced antioxidant enzyme levels and total antioxidant capacity.”

http://www.ncbi.nlm.nih.gov/pubmed/25493943

“Cannabis sativa L., also commonly called industrial hemp seed, is historically an important source of food, fibre, dietary oil and medicine; the seed contains about 30% oil and 25% protein…

Proteins from both plant and animal sources, including those of hemp seed, have been isolated and recognized as essential sources of bioactive peptides capable of exerting various in vitro and in vivo activities, such as antioxidant, antihypertensive, antimicrobial, opioid, antithrombotic, hypocholesterolemic, appetite-reducing, mineral-binding, immunomodulatory and cytomodulatory…

HMH may serve as an important ingredient to formulate antioxidant diets with potential therapeutic effects.”

[The role of endocannabinoid system in physiological and pathological processes in the eye].

Posted on April 28, 2015 by David

“Plant of Cannabis sativa/ marihuana except for its psychotropic effects possesses a range of pharmacological properties, that has been utilized for medical purposes over a period of millenia.

Investigations concerning biochemical mechanism of action of the main and most active pharmacological compound of Cannabis sativa, cannabinoid 9-THC, contributed to the discovery of cannabinoid receptors both in the central nervous system (CNS) and peripheral tissues, that mediated actions of this substance.

The discovery made possible identification of a new, endogenous signaling system referred to as the endocannabinoid system.

Besides cannabinoid receptors CB1 and CB2, the system includes it’s endogenic ligands (endocannabinoids) and compounds that participate in their biosynthesis and inactivation. Structure and functioning of the endocannabinoid system is conservative in all vertebrates.

It’s activation with plant, synthetic and endogenous cannabinoids has an influence on multiple physiological and pathological processes within the eye.”

Responsible and controlled use: Older cannabis users and harm reduction.

Posted on April 26, 2015 by David

“Cannabis use is becoming more accepted in mainstream society. In this paper, we use Zinberg’s classic theoretical framework of drug, set, and setting to elucidate how older adult cannabis users managed health, social and legal risks in a context of normalized cannabis use…

Interviewees made harm reduction choices based on preferred cannabis derivatives and routes of administration, as well as why, when, where, and with whom to use. Most interviewees minimized cannabis-related harms so they could maintain social functioning in their everyday lives. Responsible and controlled use was described as moderation of quantity and frequency of cannabis used, using in appropriate settings, and respect for non-users. Users contributed to the normalization of cannabis use through normification.

Participants followed rituals or cultural practices, characterized by sanctions that helped define “normal” or “acceptable” cannabis use. Users contributed to cannabis normalization through their harm reduction methods.

These cultural practices may prove to be more effective than formal legal prohibitions in reducing cannabis-related harms.

Findings also suggest that users with access to a regulated market (medical cannabis dispensaries) were better equipped to practice harm reduction.

More research is needed on both cannabis culture and alternative routes of administration as harm reduction methods.”

Pure cannabidiol in the treatment of malignant migrating partial seizures in infancy: a case report.

Posted on April 18, 2015 by David

“Malignant migrating partial seizures in infancy is a devastating pharmacoresistent epileptic encephalopathy of unknown etiology characterized by onset in the first 6 months of life, continuous migrating focal seizures with corresponding multifocal electroencephalographic discharges, developmental deterioration, and early mortality.

Recent widespread interest in the nonpsychoactive component of the cannabis plant, cannabidiol, as a potential treatment for refractory devastating epilepsies has led to individual trials initiated by families or physicians in states that have legalized medical marijuana with anecdotal success.

We describe a now 10-month-old boy with malignant migrating partial seizures in infancy who made developmental gains and demonstrated sustained seizure reduction with the addition of cannabidiol to his antiepileptic regimen.

This report supports a role for cannabidiol in the treatment of malignant migrating partial seizures in infancy.”

Medical marijuana for cancer.

Posted on January 17, 2015 by David

“Marijuana has been used for centuries, and interest in its medicinal properties has been increasing in recent years. Investigations into these medicinal properties has led to the development of cannabinoid pharmaceuticals such as dronabinol, nabilone, and nabiximols.

Dronabinol is best studied in the treatment of nausea secondary to cancer chemotherapy and anorexia associated with weight loss in patients with acquired immune deficiency syndrome, and is approved by the US Food and Drug Administration for those indications.

Nabilone has been best studied for the treatment of nausea secondary to cancer chemotherapy. There are also limited studies of these drugs for other conditions.

Nabiximols is only available in the United States through clinical trials, but is used in Canada and the United Kingdom for the treatment of spasticity secondary to multiple sclerosis and pain.

Studies of marijuana have concentrated on nausea, appetite, and pain.

This article will review the literature regarding the medical use of marijuana and these cannabinoid pharmaceuticals (with emphasis on indications relevant to oncology)”

http://www.ncbi.nlm.nih.gov/pubmed/25503438

“Both cannabis and cannabinoid pharmaceuticals can be helpful for a number of problems, including many affecting patients with cancer… given the limitations inherent in using oral medications to treat nausea and vomiting, inhalation of marijuana or a cannabinoid may be better than oral ingestion in treating this condition.” http://onlinelibrary.wiley.com/doi/10.3322/caac.21260/full

Reactive oxygen species-mediated therapeutic response and resistance in glioblastoma.

Posted on January 17, 2015 by David

“Glioblastoma (GBM) resistance to therapy is the most common cause of tumor recurrence, which is ultimately fatal in 90% of the patients 5 years after initial diagnosis. A sub-population of tumor cells with stem-like properties, glioma stem cells (GSCs), is specifically endowed to resist or adapt to the standard therapies, leading to therapeutic resistance.

Several anticancer agents, collectively termed redox therapeutics, act by increasing intracellular levels of reactive oxygen species (ROS).

In this study, we investigated mechanisms underlying GSC response and resistance to cannabidiol (CBD), a non-toxic, non-psychoactive cannabinoid and redox modulator.

…we demonstrated that combining CBD treatment with the inhibition of system Xc resulted in synergistic ROS increase leading to robust antitumor effects, that is, decreased GSC survival, self-renewal, and invasion.

Our investigation provides novel mechanistic insights into the antitumor activity of redox therapeutics and suggests that combinatorial approaches using small molecule modulators of ROS offer therapeutic benefits in GBM.”

Cannabidiol: promise and pitfalls.

Posted on October 28, 2014 by David

“Over the past few years, increasing public and political pressure has supported legalization of medical marijuana.

One of the main thrusts in this effort has related to the treatment of refractory epilepsy-especially in children with Dravet syndrome-using cannabidiol (CBD).

Despite initiatives in numerous states to at least legalize possession of CBD oil for treating epilepsy, little published evidence is available to prove or disprove the efficacy and safety of CBD in patients with epilepsy. This review highlights some of the basic science theory behind the use of CBD, summarizes published data on clinical use of CBD for epilepsy, and highlights issues related to the use of currently available CBD products.

Cannabidiol is the major nonpsychoactive component of Cannabis sativa.

Over the centuries, a number of medicinal preparations derived from C. sativa have been employed for a variety of disorders, including gout, rheumatism, malaria, pain, and fever.

These preparations were widely employed as analgesics by Western medical practitioners in the 19(th) century.

More recently, there is clinical evidence suggesting efficacy in HIV-associated neuropathic pain, as well as spasms associated with multiple sclerosis.”
