Pot Compound Reduces Anxiety

Posted on by

“According to clinical trial data published online in The Journal of Psychopharmacology, the administration of the non-psychoactive component of marijuana [cannabinoid cannabidiol (CBD)] reduces anxiety in subjects with social anxiety disorder (SAD).

The anti-anxiety activity of oral doses of CBD in ten subjects was assessed by investigators at the University of Sao Paulo in Brazil in a double blind, placebo-controlled trial.

Researchers concluded, “CBD reduces anxiety in SAD and that this is related to its effects on activity in limbic and paralimbic brain areas.”

This study is the first clinical trial to investigate the effects of cannabinoid cannabidiol on human pathological anxiety and its underlying brain mechanisms.

Previous studies in the context of CBD have suggested that the compound possesses anti-inflammatory activity, anti-cancer activity, and neuroprotective effects – among other therapeutic properties.

The study “Neural basis of anxiolytic effects of cannabidiol (CBD) in generalized social anxiety disorder: a preliminary report,” appeared online in The Journal of Psychopharmacology.”

Role of endocannabinoid system in mental diseases.

Posted on by

“In the last decade, a large number of studies using Delta9-tetrahydrocannabinol (THC), the main active principle derivative of the marijuana plant, or cannabinoid synthetic derivatives have substantially contributed to advance the understanding of the pharmacology and neurobiological mechanisms produced by cannabinoid receptor activation.

 Cannabis has been historically used to relieve some of the symptoms associated with central nervous system disorders. Nowadays, there are anecdotal evidences for the use of cannabis in many patients suffering from multiple sclerosis or chronic pain. Following the historical reports of the use of cannabis for medicinal purposes, recent research has highlighted the potential of cannabinoids to treat a wide variety of clinical disorders. Some of these disorders that are being investigated are pain, motor dysfunctions or psychiatric illness…

 Considering that cannabis or cannabinoid pharmaceutical preparations may no longer be exclusively recreational drugs but may also present potential therapeutic uses, it has become of great interest to analyze the neurobiological and behavioral consequences of their administration. This review attempts to link current understanding of the basic neurobiology of the endocannabinoid system to novel opportunities for therapeutic intervention and its effects on the central nervous system.”

Cannabinoid-related agents in the treatment of anxiety disorders: current knowledge and future perspectives.

Posted on by

“Rich evidence has shown that cannabis products exert a broad gamut of effects on emotional regulation. The main psychoactive ingredient of hemp, Δ9-tetrahydrocannabinol (THC), and its synthetic cannabinoid analogs have been reported to either attenuate or exacerbate anxiety and fear-related behaviors in humans and experimental animals. The heterogeneity of cannabis-induced psychological outcomes reflects a complex network of molecular interactions between the key neurobiological substrates of anxiety and fear and the endogenous cannabinoid system, mainly consisting of the arachidonic acid derivatives anandamide and 2-arachidonoylglycerol (2-AG) and two receptors, respectively termed CB1 and CB2. The high degree of interindividual variability in the responses to cannabis is contributed by a wide spectrum of factors, including genetic and environmental determinants, as well as differences in the relative concentrations of THC and other alkaloids (such as cannabidiol) within the plant itself.

The present article reviews the currently available knowledge on the herbal, synthetic and endogenous cannabinoids with respect to the modulation of anxiety responses, and highlights the challenges that should be overcome to harness the therapeutic potential of some of these compounds, all the while limiting the side effects associated with cannabis consumption. In addition the article presents some promising patents on cannabinoid-related agents.”

“Cannabis (marijuana, hashish, or cannabinoids) has been used for medical and recreational purposes for many centuries and is likely the only medicine or illicit drug that has constantly evoked tremendous interest or controversy within both the public domain and medical research. Cannabinoids appear to be able to modulate pain, nausea, vomiting, epilepsy, ischemic stroke, cerebral trauma, multiple sclerosis, tumors, and other disorders in humans and/or animals.

Cannabis acts on 2 types of cannabinoid receptors, the CB1 and CB2 receptors, which are distributed mainly in the brain and immune system, respectively. In the brain, CB1 receptors are also targeted by endogenous cannabinoids (i.e., endocannabinoids) such as anandamide (AEA), 2-arachidonylglycerol, and arachidonylethanolamide…

…since adult hippocampal neurogenesis is suppressed following chronic administration of opiates, alcohol, nicotine, and cocaine, the present study suggests that cannabinoids are the only illicit drug that can promote adult hippocampal neurogenesis following chronic administration…

Cannabinoids promote embryonic and adult hippocampus neurogenesis and produce anxiolytic- and antidepressant-like effects.”

The efficacy and safety of nabilone (a synthetic cannabinoid) in the treatment of anxiety.

Posted on by

“The anxiolytic properties of nabilone, a synthetic cannabinoid resembling the natural cannabinoids, were studied in 25 outpatients suffering from anxiety. The drug was compared with a placebo in a double-blind manner over a 28-day treatment period. Patients were seen weekly by the physician and were rated by the Hamilton Rating Scale for Anxiety and the Patient’s Global Evaluation as well as by patient-rated evaluations. The results of the study showed a dramatic improvement in anxiety in the nabilone group when compared with placebo (P less than 0.001). Side effects reported were dry mouth, dry eyes, and drowsiness. Patients did not report any of the subjective “altered state” experience of marihuana.”

Inhibition of endocannabinoid catabolic enzymes elicits anxiolytic-like effects in the marble burying assay

Posted on by

“Cannabinoids have long been shown to have a range of potential therapeutic effects, including antiemetic actions, analgesia, and anxiolysis. These data indicate that elevation of AEA or 2-AG reduces marble burying behavior and suggest that their catabolic enzymes represent potential targets for the development of new classes of pharmacotherapeutics to treat anxiety-related disorders.

Marijuana is commonly smoked to reduce feelings of stress and anxiety… much interest has been generated by the discovery of the endogenous cannabinoid (i.e. endocannabinoid; eCB) system as a source of targets for the development of new therapeutic treatments of a range of ailments including anxiety and depression…”

“Some are using marijuana as their drug of choice to curb anxiety.”

Marijuana Anxiety Disorders
 

 “A thimbleful is all it takes. After a day’s work, I pinch off a small amount of marijuana and put it in a steel-tooth grinder. The flowers, covered in tiny white diamonds of THC, release a piney scent when crushed. I turn on the TV, and instead of taking a glass of wine with my evening news, I take out my vaporizer and set it on the coffee table.

Outside the walls of my bungalow in Oakland, California, I can hear the rush-hour traffic, but I’ve already changed into my Big Lebowski–style robe and slippers. I tap the ground flakes into a canister that I attach to another piece, this one with a bag on the end, and set both on the vaporizer. I flip the switch, and the bag slowly inflates with plumes of white smoke. Once it’s fully clouded, I attach a mouthpiece to the canister, put this to my lips, and press. On the inhale, the cannabinoids taste like sunned grass. My prescription for anxiety disorder didn’t always begin and end with an herb. But I’ve run through enough pharmaceutical drugs to know that pot dulls my panic better than any pill.”

Marijuana nutrients found to help prevent Alzheimer’s disease

Posted on by
“A study conducted by scientists at Scripps Research Institute in California has found that, contrary to marijuana’s reputation, the ingredients of the drug can actually fight off the memory-impairing effects of Alzheimer’s disease.The researchers found that the active ingredient in marijuana — delta-9-tetrahydrocannabinol, or THC — is responsible for the positive effect, as it can prevent the breakdown of the neurotransmitter acetylcholine even better than commercially marketed prescription drugs.

The study also showed that THC could completely prevent the enzyme acetylcholinesterase (AchE) from forming amyloid plaques, whereas twice as much donepezil and tacrine — the two drugs approved for Alzheimer’s treatment — only reduced such clumping by 22 and 7 percent, respectively, the researchers reported in the journal Molecular Pharmaceutics. This led the scientists to conclude that a more effective Alzheimer’s drug could be developed in the future.”

Medical Marijuana as Effective Treatment for Alzheimer’s Disease

Posted on by

“Regular low dose cannabis smoking might keep Alzheimer’s away, according to marijuana research by professor Gary Wenk and associate professor Yannic Marchalant of the Ohio State Department of Psychology. Wenk’s studies show that a low dosage in the morning of a certain cannabinoid, a component in marijuana, reversed memory loss in older rats’ brains. In his study, an experimental group of old rats received a dosage, and a control group of rats did not. The old rats that received the drugs performed better on memory tests, and the drug slowed and prevented brain cell death.”

“Alzheimer’s is a disease unique to humans…, but rat brains are similar enough to human brains to serve as partial models for humans, Wenk said.

… marijuana is the first substance that has worked on older brains in experiments.”

Alzheimer’s: Marijuana as Effective Medicine

Posted on by

“Cannabis is getting much positive publicity and seems to be regaining its popularity of one hundred years ago when it was the most widely used drug for about 100 different diseases. There is a big toodoo nowadays about Alzheimers which has turned into almost an epidemic for old folks with some even in their 50’s. So far nobody seems to have put a handle on it and I won’t either.The latest information seems to be that there are senile plaques in the cerebral cortex and subcortical grey matter but whether these plaques are a cause or effect seems to be up for grabs.

I don’t know either. My Merck manual says that four million Americans have it, mostly those over 60 years old. It is a very expensive disease for nursing homes and nursing care probably at least 100 billion dollars per year.

As a Medical Marijuana doctor, I jumped into this fracas when I heard that a lady spouse of an Alzheimers patient went to a Medical Marijuana Advisory Committee meeting of The Oregon Medical Marijuana Program (OMMP) and demanded that her husband be given a permit. She was successful and the medical statistics from OMMP indicate that somewhat less than 50 people have Marijuana permits for this disease. It is called Alzheimers Rage.

The above really didn’t surprise me because there are several Central Nervous System (CNS) diseases for which Cannabis/Marijuana (C/MJ) works very well. These include ALS, Epilepsy, Multiple Sclerosis, Parkinsonism, PTSD and Traumatic Brain Injuries (TBIs). I don’t know if anyone has figured out why C/MJ works for these conditions but why ask if those suffering say that C/MJ works.

Tod Mikiyuria, the foremost scholar in this area, says that C/MJ works as a modulator which is a term of general meaning which possibly just means that it works.

The standard drugs are almost worthless, many seem to be Cholinergics related to Acetyl Choline, the standard Neuro transmitter nerve cell to cell and nerve cell to muscle. At any rate C/MJ seems to work better than any of the heavily advertised drugs.

Cannabis/Marijuana is simultaneously getting much positive publicity and seems to be regaining its popularity of one hundred years ago when it was the most widely used drug for about 100 different diseases.

Those of us advocates for Medical Marijuana who have suffered scorn and derision for DEVIL WEED causing REEFER MADNESS can finally say
