The endocannabinoid system, cannabinoids, and pain.

“The endocannabinoid system is involved in a host of homeostatic and physiologic functions, including modulation of pain and inflammation… Exogenous plant-based cannabinoids (phytocannabinoids) and chemically related compounds, like the terpenes, commonly found in many foods, have been found to exert significant analgesic effects in various chronic pain conditions.

Currently, the use of Δ9-tetrahydrocannabinol is limited by its psychoactive effects and predominant delivery route (smoking), as well as regulatory or legal constraints.

 However, other phytocannabinoids in combination, especially cannabidiol and β-caryophyllene, delivered by the oral route appear to be promising candidates for the treatment of chronic pain due to their high safety and low adverse effects profiles.

This review will provide the reader with the foundational basic and clinical science linking the endocannabinoid system and the phytocannabinoids with their potentially therapeutic role in the management of chronic pain.”

Study: Marijuana’s Active Ingredient May Shrink Cancerous Tumors – FoxNews

“The active ingredient in marijuana appears to reduce tumor growth…

The researchers showed giving THC to mice with cancer decreased tumor growth and killed cells off in a process called autophagy.

“Our findings support that safe, therapeutically efficacious doses of THC may be reached in cancer patients,” Guillermo Velasco of Complutense University in Madrid and colleagues reported in the Journal of Clinical Investigation…

Other research has shown benefits, such as staving off Alzheimer’s, and many doctors view THC as a valuable way to treat weight loss associated with AIDS, and nausea and vomiting associated with chemotherapy in cancer patients.

Velasco and his team’s study included an analysis of two tumors from two people with a highly aggressive brain cancer which showed signs of autophagy after receiving THC.

The researchers said the findings could pave the way for cannabinoid-based drugs to treat cancer…”

Chemicals in marijuana ‘protect nervous system’ against MS

Cannabis

“Chemical compounds found in marijuana can help treat multiple sclerosis-like diseases in mice by preventing inflammation in the brain and spinal cord, according to a study reported in the Journal of Neuroimmune Pharmacology.

“Inflammation is part of the body’s natural immune response, but in cases like MS, it gets out of hand,” says Dr. Ewa Kozela of Tel Aviv University, Israel.

“Our study looks at how compounds isolated from marijuana can be used to regulate inflammation to protect the nervous system and its functions.”

Dr. Kozela and colleagues set out to see if the known anti-inflammatory properties of two substances found in marijuana – the cannabinoids known as tetrahydrocannabinol (THC) and cannabidiol (CBD) – could also be applied to the treatment of inflammation associated with MS.

With either THC or CBD, the researchers treated immune cells that specifically target and harm the brain and spinal cord. In response to both chemicals, the immune cells, isolated from paralyzed mice, produced fewer inflammatory molecules, particularly interleukin 17 (IL-17).

Interleukin 17 “is strongly associated with MS and very harmful to nerve cells and their insulating covers,” the researchers say. They conclude:

“The presence of CBD or THC restrains the immune cells from triggering the production of inflammatory molecules, and limits the molecules’ ability to reach and damage the brain and spinal cord.”

Chemicals in Marijuana Could Help Treat MS

“TAU researchers have found that chemicals in marijuana could help treat multiple sclerosis.

Multiple sclerosis is an inflammatory disease in which the immune system attacks the nervous system. The result can be a wide range of debilitating motor, physical, and mental problems. No one knows why people get the disease or how to treat it.

Parkinson’s Symptoms Reduced by Smoking Cannabis – Parkinson Research Foundation

Cannabis_Clones_in_Box

 “Ruth Djaldetti, M.D., of Tel Aviv University in Israel, presented the findings of her research at a recent International Congress on Parkinson’s Disease and Movement Disorders.  She reported improvement in tremor, pain, rigidity and bradykinesia (slowness of movement).  Twenty subjects, all in their mid-sixties, and were rated using the Unified Parkinson’s Disease Rating Scale (UPDRS) both before and after smoking.  Their overall “before” scores were over 30 and within 30 minutes of smoking, their scores dropped to 24..  Their tremor scores averaged 7.5 on the UPDRS before and dropped to a score of 3.5 after smoking cannabis.  Bradykinesia scores dropped from 13.2 to 8.6 and rigidity went from 7.4 to 6.4.  Dr. Djaldetti also saw a marked relief in the pain her subjects were experiencing and this relief of pain led to better sleep and feeling more rested.

This bears out the results of other studies.  A study done in Great Britain that was published in 2011 found the principal ingredient in cannabis provided neuroprotection for people with Parkinson’s disease.  Its neuroprotective properties included reduction of inflammation and control of spasms, making it an ideal drug for treating Parkinson’s.  However, its confusing legal status make it very difficult for people to obtain or consider using and for doctors to even recommend to patients.

Another interesting study done in 2010 found that cannabinoid receptors are located in many parts of the brain and that cannabinoids are produced naturally in the brain.  People with Parkinson’s have even higher levels of endocannabinoids (cannabinoids produced within the brain).  The main ingredient in cannabis, Tetrahydrcannibol (THC) actually increases dopamine production temporarily.  Cannabidiol (CBD) another component of cannabis, also provides neuroprotective properties and has been shown to reduce dystonias .  CDB could be a very vital improvement for treating Parkinson’s, and a recent study has shown it useful in treating certain cancers as well.

While there have been many, many people reporting the anecdotal benefits of smoking cannabis, clinical trials are lagging behind.  Laboratory and animal studies have shown many benefits, but perplexing issues around the legality of cannabis are slowing the efforts and impeding progress.”

Δ9-TETRAHYDROCANNABINOL IS PROTECTIVE THROUGH PPARγ DEPENDENT MITOCHONDRIAL BIOGENESIS IN A CELL CULTURE MODEL OF PARKINSON’S DISEASE

“Cannabinoids such as Δ9-tetrahydrocannabinol (Δ9-THC) are neuroprotective in animal and cell culture models of Parkinson’s disease (PD).

In a PD cell culture model we recently demonstrated that Δ9-THC is neuroprotective through activation of the nuclear receptor peroxisomal proliferator-activated receptor γ (PPARγ)…

Here we investigate the effect of Δ9-THC and pioglitazone on mitochondrial biogenesis…

CONCLUSIONS:

Even though Δ9-THC and pioglitazone are both protective against MPP+ only Δ9-THC induces PPARγ dependent mitochondrial biogenesis, a mechanism that may be beneficial for the treatment of PD.”

Dronabinol, a cannabinoid agonist, reduces hair pulling in trichotillomania: a pilot study.

“Trichotillomania is characterized by repetitive pulling causing noticeable hair loss. Pharmacological treatment data for trichotillomania are limited.

Dronabinol appears to reduce the exocitotoxic damage caused by glutamate release in the striatum and offers promise in reducing compulsive behavior.

 

RESULTS:

The medication was well-tolerated, with no significant deleterious effects on cognition.

CONCLUSIONS:

This study, the first to examine a cannabinoid agonist in the treatment of trichotillomania, found that dronabinol demonstrated statistically significant reductions in trichotillomania symptoms, in the absence of negative cognitive effects.

Pharmacological modulation of the cannabinoid system may prove useful in controlling a range of compulsive behaviors…”
