Cannabis by product helps reduce effects of Parkinson disease medication

Posted on by

“Researchers from Brazil’s prestigious University of Sao Paulo have discovered that marihuana contains substances which can help ease the collateral effects of medicines prescribed to patients suffering from Parkinson disease.”

Brazilian researchers have tested the positive effects of canabiodiol 

“Six patients with Parkinson were given during a whole month small doses of “canabiodiol” one of the 400 substances in marihuana, following which encouraging results were confirmed according to scientists from the Riberao Preto Medicine School from the SP University.

“Patients with Parkinson developed improvements in their sleeping alterations, in their psychotic symptoms and could even reduce their trembling” said psychiatrist Jose Alexander Crippa, Neuro-sciences Department professor.

The paper on the discovery was published last November and next year an additional paper with test results on the anxiolytic effects of “canabiodiol” in patients with obsession and compulsion disorders will be released.

A group of voluntary patients with obsessive and compulsive conducts were medicated with the substance 70 minutes before facing situations that forced them into anxiety fits, and “improvements were evident”.”

New Study: Cannabinoids Protect the Brain and Heart From Injury

Posted on by

“Cannabis is in the news again for its purported medicinal benefits, with researchers in Israel last week indicating it may help prevent trauma to the brain in certain circumstances and may also help with cardiac problems. A few months ago an English pharmaceutical company that manufactures cannabinoids announced it was developing a new treatment for epilepsy using them.”

“Prof. Yosef Sarne in the Adelson Center for the Biology of Addictive Diseases in the Department of Physiology and Pharmacology at Tel Aviv University says that cannabis has neuro-protective qualities. He has found that extremely low doses of tetrahydrocannabinol or THC- the psychoactive component of marijuana- can protect the brain from long-term cognitive damage in the wake of injury from hypoxia (lack of oxygen), seizures, or toxic drugs.”

GW Pharmaceuticals: Giving New Meaning To ‘High Potential’

Posted on by

“GW Pharmaceuticals (GWPH) is an UK-based biopharmaceutical company focused on the discovery and development of cannabinoid-based products for a wide range of indications. GW has established a technology platform based on genetically modified cannabis plants and has become a leader in plant-derived cannabinoid therapeutics.

 GW’s lead program is Sativex, a cannabis extract based oromucosal spray whose main actives are the cannabinoids delta-9- tetrahydrocannabinol (THC), and cannabidiol (CBD). It is approved for the treatment of multiple sclerosis (MS) spasticity in 21 countries outside of the U.S and already marketed in seven countries (eight following Italian launch in Q213).

…While MS spasticity has provided proof-of-concept in the worldwide approvability of Sativex, a more meaningful commercial opportunity is in the treatment of opioid-refractory cancer pain. Sativex has been tested in two Phase II trials in cancer pain. The trials have demonstrated that Sativex is safe and effective when used in addition to opioids in patients whose cancer pain is not sufficiently managed by opioids alone. Based on these results, GW has initiated three Phase III trials. The first two are expected to complete during 2014 and support an FDA filing.”

Delta–9 Tetrahydrocannabinol inhibits growth and metastasis of lung cancer – Harvard University

Posted on by

“Lung cancer is the major cause of cancer-related mortality worldwide.Many of these over-express epidermal growth factor receptor(EGFR), and are usually highly aggressive and resistant to chemotherapy.

Recent studies have shown that {Delta}-9 Tetrahydrocannabinol (THC),the major component of Cannabis sativa, possess anti-tumor propertiesagainst various types of cancers.

 However, not much is knownabout its effect on lung cancer. In this study, we sought tocharacterize the effect of THC on EGF-induced growth and metastasisof human non small lung cancer cell (NSCLC) lines A549 and SW-1573.

We demonstrate that these cell lines and primary tumor samplesderived from lung cancer patients express cannabinoids receptorsCB1 and CB2, the known targets for THC action. We further showthat THC inhibits EGF-induced growth in these cell lines. Inaddition THC attenuated EGF-stimulated chemotaxis and chemoinvasion.Next we characterized the effect of THC on in vivo lung cancergrowth and metastasis in a murine model. A549 cells were implantedin SCID mice (n=6 per group) through subcutaneous and intravenousinjections to generate subcutaneous and lung metastatic cancer,respectively. THC (5mg/kg body wt.) was administered once dailythrough intraperitoneal injections for 21 days. The mice wereanalyzed for tumor growth and lung metastasis.

 A significantreduction (~50%) in tumor weight and volume were observed inTHC treated animals compared to the vehicle treated animals.THC treated animals also showed a significant (~60%) reductionin macroscopic lesions on the lung surface in comparison tovehicle treated control. Immunohistochemical analysis of thetumor samples from THC treated animals revealed anti-proliferativeand anti-angiogenic effects of THC with significant reductionin staining for Ki67, a proliferative marker and CD31, an endothelialmarker indicative of vascularization. Investigation into thesignaling events associated with reduced EGF-induced functionaleffects revealed that THC also inhibits EGF-induced Akt phosphorylation.Akt is a central signaling molecule of EGFR-mediated signalingpathways and it regulates a diverse array of cellular functions,including proliferation, angiogenesis, invasion and apoptosis.

Cumulatively, these studies indicate that THC has anti-tumorigenic and anti-metastatic effects against lung cancer. Novel therapies against EGFR overexpressing, aggressive and chemotherapy resistant lung cancers may include targeting the cannabinoids receptors.”

Marijuana Derivative May Offer Hope in Cocaine Addiction – TIME

Posted on by

“A new study in mice has found that activating a receptor affected by marijuana can dramatically reduce cocaine consumption. The research suggests that new anti-addiction drugs might be developed using synthetic versions of cannabidiol (CBD), the marijuana component that activates the receptor—or even by using the purified natural compound itself.

Researchers formerly believed that the receptor, known as CB2, was not found in the brain and that therefore CBD had no psychoactive effects. But a growing body of research suggests otherwise. After THC, CBD is the second most prevalent active compound in marijuana.”

Marijuana tied to better blood sugar control – NBC

Posted on by

“People who had used marijuana in the past month had smaller waists and lower levels of insulin resistance – a diabetes precursor – than those who never tried the drug, in a new study.

The findings, based on surveys and blood tests of about 4,700 U.S. adults, aren’t enough to prove marijuana keeps users thin or wards off disease. And among current pot smokers, higher amounts of marijuana use weren’t linked to any added health benefits, researchers reported in The American Journal of Medicine.

“These are preliminary findings,” said Dr. Murray Mittleman, who worked on the study at Beth Israel Deaconess Medical Center in Boston.

“It looks like there may be some favorable effects on blood sugar control, however a lot more needs to be done to have definitive answers on the risks and potential benefits of marijuana usage.”

Although pot smoking is a well-known cause of “the munchies,” some previous studies have found marijuana users tend to weigh less than other people, and one suggested they have a lower rate of diabetes. Trials in mice and rats hint that cannabis and cannabinoid receptors may influence metabolism.”

New study suggests marijuana prevents diabetes

Posted on by
“A provocative study comes right as Massachusetts begins a new medical marijuana law. The theory? Using pot could lower your risk of diabetes.

We’ve all heard about “the munchies,” that urge to eat more when under the influence of marijuana.

But a new study published by the American Journal of Medicine finds despite the habit among recreational pot users to take in more calories, it doesn’t lead to weight gain. And the benefits of marijuana don’t end there.

“What we saw was that people who were current users of marijuana had improved sensitivity to insulin compared to non-users, they had better good cholesterol, and reduced waist circumference,” said Dr. Murray Mittleman, lead author and researcher at Harvard Medical School.

The research included more than 4,600 men and women participating in a national nutrition survey in the last decade. Marijuana users maintained more normal blood sugar levels compared to non-users, which meant their bodies were regulating insulin well. That puts them at a lower diabetes risk.

“When somebody smokes marijuana there are a variety of compounds that are present in marijuana, some of which may partially block some of the receptors as well as stimulate others, which is why people use it presumably,” said Mittleman.

Blocking certain receptors could be what’s behind the health benefits found in the study. Researchers say the findings point to the importance of more marijuana research.

“We just had the medical marijuana passed here in Massachusetts. But two states now have recreational use approved and we really are opening up the doors to the use of this drug. Yet we don’t have the information that we need to make sensible recommendations,” said Mittleman.

As for the latest findings, could marijuana be the next diabetes drug?”

Marijuana Blood Sugar: Can Pot Help Curb Diabetes?

Posted on by
“Can marijuana use lower one’s risk of developing diabetes through controlling blood sugar levels? The answer is yes, according to a recently released study published in the American Journal of Medicine.
 
The research, which was conducted between 2005 and 2010 and included more than 4,600 men and women in a National Health and Nutrition Examination Survey, found that compounds in cannabis could help to control blood sugar levels.
 

Despite its reputation for increasing one’s appetite, three prior studies have also shown that pot use often leads to a reduced chance of becoming obese, resulting in a lower body-mass-index and less of a chance of developing diabetes, notes Time.”

 

Marijuana has newly discovered benefits with profound possibilities

Posted on by
Benefits of marijuana may include help for diabetes type 2, obesity, 'good' cholesterol and more  

“According to new scientific evidence, breaking out the bong for some Mother Nature has multiple health benefits. According the American Journal of Medicine (AJA), the benefits are remarkable and some fly in the face of what should be expected from a drug that produces the ‘munchies’, a rabid appetite. The AJA reports no weight gain from marijuana users and reports marijuana may help prevent diabetes type 2 and obesity.

These benefits apply specifically to perennial pot smokers and not to former smokers.”
