Cannabis, a complex plant: different compounds and different effects on individuals.

Posted on by

“Cannabis is a complex plant, with major compounds such as delta-9-tetrahydrocannabinol and cannabidiol, which have opposing effects. The discovery of its compounds has led to the further discovery of an important neurotransmitter system called the endocannabinoid system.

This system is widely distributed in the brain and in the body, and is considered to be responsible for numerous significant functions.

There has been a recent and consistent worldwide increase in cannabis potency, with increasing associated health concerns. A number of epidemiological research projects have shown links between dose-related cannabis use and an increased risk of development of an enduring psychotic illness. However, it is also known that not everyone who uses cannabis is affected adversely in the same way.

What makes someone more susceptible to its negative effects is not yet known, however there are some emerging vulnerability factors, ranging from certain genes to personality characteristics.

 In this article we first provide an overview of the biochemical basis of cannabis research by examining the different effects of the two main compounds of the plant and the endocannabinoid system, and then go on to review available information on the possible factors explaining variation of its effects upon different individuals.”

Texas A&M Pharmacy Researcher Fights Cancer, Pain With New Cannabinoid Receptor Drug

“Dr. Lu has been working to find new types of chemotherapeutic drugs that both kill pancreatic cancer and suppress the cancer pain at the same time by targeting a special G-protein coupled receptor that belongs to the biological system responsible for the effects of Tetrahydrocannabinol (THC), a compound derived from some varieties of cannabis (hemp) or made synthetically, that is the primary psychoactive agent in marijuana and hashish.

 Dr. Lu says pancreatic cancer cells have more type 2 cannabinoid receptors than do healthy cells.

 Consequently, drug molecules that selectively activate this receptor can induce cancer cell death without affecting normal pancreatic cells, noting that when given to mice with pancreatic tumors, the molecule prevented tumor growth and suppressed the spread of cancer to healthy organs.

 Meanwhile, this class of compounds also generates painkillers comparable to morphine’s pain killing effect…”

Around-the-clock oral THC effects on sleep in male chronic daily cannabis smokers.

Posted on by

“Δ9-tetrahydrocannabinol (THC) promotes sleep in animals; clinical use of THC is associated with somnolence (sleepiness)…

These findings suggest that tolerance to the somnolent effects of THC may have occurred…

Somnolence from oral THC may dissipate with chronic, high-dose use.

This has implications for patients who may take chronic oral THC for medicinal purposes, including cannabis dependence treatment.”

Marijuana stops child’s severe seizures

Posted on by

 

“Saundra Young of CNN.com delved into the heated debate of medical marijuana and children, in her story about a little girl who has a rare, and severe form of epilepsy called Dravet Syndrome. While the debate continues, the pro-legalization side may have won a small victory in the form of Charlotte Figi, 6, who was given her life back by marijuana…

Desperate for a treatment, Charlotte’s father Matt searched the Internet and eventually found a boy with a similar case in which medical marijuana helped his seizures. The Figi’s turned to the Stanley brothers, one of Colorado’s largest marijuana growers and dispensary owners, for help.

“These six brothers were crossbreeding a strain of marijuana low in THC, the compound in marijuana that’s psychoactive, and high in CBD, which has medicinal properties but no psychoactivity,” writes Young. But the Stanley brothers didn’t know what to do with this particular strain, as no one seemed to want to buy it. Then they met Charlotte.

The first time Charlotte tried a small dose of cannabis oil, the results were astounding:

“When she didn’t have those three, four seizures that first hour, that was the first sign,” Paige recalled. “And I thought well, ‘Let’s go another hour, this has got to be a fluke.'”

The Stanley brothers started the Realm of Caring Foundation, a nonprofit organization that provides this particular strain of medical marijuana to adults and children suffering from a host of diseases. The strain used by Charlotte and 41 other patients is affectionately called Charlotte’s Web.

Charlotte’s seizures stopped for seven days after her first dose and today she is eating, and walking on her own — even riding a bike, her parents say. Charlotte gets a dose of the cannabis oil twice a day in her food and her seizures are down to 2 to 3 per month.

“I literally see Charlotte’s brain making connections that haven’t been made in years,” Matt said. “My thought now is, why were we the ones that had to go out and find this cure? This natural cure? How come a doctor didn’t know about this? How come they didn’t make me aware of this?”

Medical marijuana stopped girl’s seizures when nothing else would – msn

“Charlotte Figi had her first seizure in 2006, when she was 3 months old. Her parents, Matt and Paige Figi, had every test conducted, yet no cause could be found. Years passed, and the seizures continued. Charlotte took medications, but she stopped developing cognitively. She was finally diagnosed with a severe form of epilepsy, Dravet Syndrome. Matt discovered the case of a boy with Dravet who’d been helped by low-level THC medical marijuana. By that point, Charlotte couldn’t walk, talk or eat, and she was having up to 300 grand mal seizures a week.

Desperate to find a solution, Matt and Paige applied for a medical marijuana card, making Charlotte, then 5, the youngest applicant in Colorado. They gave her a small amount of cannabis oil. The seizures stopped. Now Charlotte takes the oil twice daily with food, has only a few seizures a week, and is walking, talking and riding her bike. “My thought now is why were we the ones that had to go out and find this cure? This natural cure?” says Matt. “How come [a doctor] didn’t make me aware of this?””

Fact: Cannabis Kills MRSA, Disrupts Prion Diseases

Posted on by

“Marijuana is a potent antibiotic that can kill methicillin-resistant Staphylococcus aureus and disrupt the progression of prion diseases such as Mad Cow disease and Creutzfeld-Jakob disease — just don’t expect the federal government to tell you any of this.”

A MRSA lesion

“Scientists from Italy and the United Kingdom reported in the August 2007 issue of the Journal of Natural Products that the main active ingredient in weed, THC, as well as four other pot molecules “showed potent antibacterial activity against six different strains of MRSA of clinical relevance.”

Pot also stops prions,  a type of protein that can cause neurodegenerative diseases that are invariably fatal. Once prions get into a brain they replicate rapidly and shred brain tissue “resulting in a ‘spongiform’ appearance on post-mortem histological examination of neural tissue.”

In 2007, American and French researchers reported that pot molecule cannabidiol “prevents prion accumulation and protects neurons against prion toxicity” in the Journal of Neuroscience.

Cannabidiol inhibited prion accumulation in mouse and sheep prion disease cell cultures and inhibited prion formation in the brain of infected mice given injections of CBD. “The authors conclude that CBD likely represents a new class of anti-prion drugs.””

Marijuana Kills MRSA and Inhibits Prions That Cause Neurodegenerative Disease; Still Recognized by Feds As a Dangerous Drug

Posted on by

“Research indicates that marijuana could effectively fight off MRSA, as well as prions — the proteins that cause mad cow disease and Creutzfeld-Jakob disease.”

(Photo : Flickr, "it was 3 a.m.") Pot's constituent molecules kill bacteria and inhibit the formation of prions, a protein that can cause neurodegenerative diseases.

“New research reveals that several marijuana ingredients exhibit a potent antibiotic capacity in cases of methicillin-resistant Staphylococcus aureus (MRSA) infections as well as the ability to fight off proteins called prions that can lead to Mad Cow disease and Creutzfeld-Jakob disease (CDJ).”

Evaluation of the potential of the phytocannabinoids, cannabidivarin (CBDV) and Δ9 -tetrahydrocannabivarin (THCV), to produce CB1 receptor inverse agonism symptoms of nausea in rats.

Posted on by

“The cannabinoid 1(CB1 ) receptor inverse agonists/antagonists, rimonabant (SR141716, SR) and AM251, produce nausea and potentiate toxin-induced nausea by inverse agonism (rather than antagonism) of the CB1 receptor. Here, we evaluated two phytocannabinoids, cannabidivarin (CBDV) and Δ9 -tetrahydrocannabivarin (THCV) for their ability to produce these behavioural effects characteristic of CB1 receptor inverse agonism in rats.

…we investigated the potential of THCV and CBDV to produce conditioned gaping (measure of nausea-induced behaviour),..

THC, THCV  and CBDV suppressed LiCl-induced conditioned gaping, suggesting anti-nausea potential…

The pattern of findings indicates that neither THCV nor CBDV produced a behavioural profile characteristic of CB1 receptor inverse agonists.

As well, these compounds may have therapeutic potential in reducing nausea.”
