Following cloning of the endogenous receptor for THC, namely the CB1R, endogenous CB1R ligands, or “endocannabinoids” (eCBs) were discovered, namely anandamide (AEA) and 2-arachidonoylglycerol (reviewed in ). The CB1R is an inhibitory Gi/o protein-coupled receptor that is mainly localized to nerve terminals, and is expressed on both γ-aminobutryic acid-ergic and glutamatergic neurons. eCBs are fatty acid derivatives that are synthesized on demand in response to neuronal depolarization and Ca2+ influx, via cleavage of membrane phospholipids. The primary mechanism by which eCBs regulate synaptic function is retrograde signaling, wherein eCBs produced by depolarization of the postsynaptic neuron activate presynaptic CB1Rs, leading to inhibition of neurotransmitter release . The “eCB system” includes AEA and 2-arachidonoylglycerol; their respective degradative enzymes fatty acid amide hydroxylase (FAAH) and monoacylglycerol lipase; the CB1R and related CB2 receptor (the latter expressed mainly in the periphery); as well as several other receptors activated by eCBs, including the TRPV1 receptor, peroxisome proliferator-activated receptor-γ, and G protein-coupled 55 receptor, which functionally interact with CB1R signaling (reviewed in [21, 24]). Interactions with the TRPV1 receptor, in particular, appear to be critical in regulating the extent to which eCB release leads to inhibition or facilitation of presynaptic neurotransmitter release . The TRPV1 receptor is a postsynaptic cation channel that underlies sensation of noxious heat in the periphery, with capsacin (hot chili) as an exogenous ligand. TRPV1 receptors are also expressed in the brain, including the amygdala, periaqueductal grey, hippocampus, and other areas [26, 27].
CBD molecules can bind to either CB1 or CB2 receptors. CB1 receptors are found most densely in the central and peripheral nervous system. CB2 receptors are found in the brain, the immune system, and the gastrointestinal systems. Basically, these receptors are found all throughout your body and in part, describe why CBD can impact many different conditions.
Research conducted by Schier et al. (2012) aimed to review the literature of cannabidiol (CBD) as an anxiolytic due to the fact that it is non-psychotomimetic. Researchers gathered scientific publications from English, Portuguese, and Spanish databases. All compiled articles analyzed the anxiolytic effects of cannabidiol from both human and animal model studies.
In the past few years, just such a cure has seemingly presented itself. Amid the less common remedies that can be found on the internet—special diets, meditation, biofeedback, surgical implants—a new product has recently gained prominence: CBD oil (sometimes known simply as “hemp oil”), so named for its chief chemical compound, cannabidiol, which occurs naturally in cannabis plants. In online forums and news articles, CBD has been hailed as a new frontier in epilepsy treatment, with parents testifying that it managed to stop their children’s seizures when nothing else could.
I’ve been experiencing panic attacks since I was 21 year olds. I am now 48. They are psychologically debilitating with depression repercussions for weeks after. I’ve tried everything – drugs, psychotherapy, meditation, breathing exercises etc. I understand the source of them and psychosis of it – but have never solved them and have pretty much given up hope. I also go through waves of anxiety – which tend to heighten the chance of a panic attack, but the two are not always correlated. Living in CO and being surrounded by CBD discussions, I finally decided to look up and see what CBD might do. Given this thread of info and responses, I’m going to start experimenting with with CBD. I will report back on the effects (maybe over six months)…and after some more research on the best place to start. THANK YOU for this article and information and everyone who has written here. It brings me to tears!
This is a topic I am asked about all the time, and have been for years: how does cannabis help sleep and health? I’ve heard that the number-two reason why people smoke or use cannabis is for sleep. Considering the recent passing of the recreational use of cannabis in California and other several states I think it is high time (pun intended!) to look at understanding CBD, one of the most active ingredients in medical cannabis.
Likewise, selective serotonin reuptake inhibitors (SSRIs) and selective serotonin and norepinephrine reuptake inhibitors (SNRIs) may interfere with sleep architecture and decrease restorative sleep, leading to increased awakenings, reduced REM sleep, increased REM latency, as well as increased periodic limb movement during sleep (Feige et al., 2002). In addition, SSRIs and SNRIs have been associated with REM sleep without atonia, characterized by increased tonic or phasic motor activity in electromyographic channels during REM sleep (Schenck et al., 1992; American Academy of Sleep Medicine, 2014; Lee et al., 2016).
A 2013 case report conducted in Canada evaluated the beneficial effects of cannabis oil on a 14-year-old female patient diagnosed with acute lymphoblastic leukemia, also known as ALL. For this particular patient, a standard bone marrow transplant, aggressive chemotherapy and radiation therapy were revoked, with treatment being deemed a failure after 34 months. She was extremely ill and severely underweight at this time.
That's why it's being increasingly used as a sleep aid, she says. "The major reason why most people don't sleep is because they're stressed out, they're anxious, they can't shut their brain off," she explains. "What CBD does is calm down your body's stress response and bring those cortisol and adrenaline levels back to baseline." Science is scant, but what studies we do have back that up: CBD may increase the amount of time you sleep, according to an animal study published in the Journal of Psychopharmacology, and improve insomnia, research in the journal Current Psychiatry Reports found.
After months of visiting doctors and sitting through tests like a human lab rat, it was determined that there was a slight anomaly in the anatomy of my temporal lobe—the part of the brain that controls hearing, speech, and auditory comprehension—which explains why every time I have a seizure, I suddenly don’t understand the English language. Epilepsy can’t be cured, so the only course of action available for me was to take a medication every day for the rest of my life. My neurologist prescribed a few different anti-convulsant medications, but they all made me feel tired, depressed, slow, and unlike myself—until finally, I found one that was slightly better than the rest.
Cannabis sativa, a species of the Cannabis genus of flowering plants, is one of the most frequently used illicit recreational substances in Western culture. The 2 major phyto- cannabinoid constituents with central nervous system activity are THC, responsible for the euphoric and mind-altering effects, and CBD, which lacks these psychoactive effects. Preclinical and clinical studies show CBD possesses a wide range of therapeutic properties, including antipsychotic, analgesic, neuroprotective, anticonvulsant, antiemetic, antioxidant, anti-inflammatory, antiarthritic, and antineoplastic properties (see [11, 12, 16–19] for reviews). A review of potential side effects in humans found that CBD was well tolerated across a wide dose range, up to 1500 mg/day (orally), with no reported psychomotor slowing, negative mood effects, or vital sign abnormalities noted .
The interesting thing about CBD and sleep is that in small to medium doses, CBD is mildly alerting – stimulating the same receptors as caffeine. However, several patients with insomnia report that consuming CBD oil (in tincture or extract form) a few hours before bed leads to a great night’s sleep. So why do the anecdotal results contradict the reported medical studies?
Vaney C., Heinzel-Gutenbrunner M., Jobin P., Tschopp F., Gattlen B., Hagen U., et al. (2004). Efficacy, safety and tolerability of an orally administered cannabis extract in the treatment of spasticity in patients with multiple sclerosis: a randomized, double-blind, placebo-controlled, crossover study.

Regardless of how CBD oil induces hippocampal neurogenesis, the growth of new brain cells may be enough to decrease anxiety. A report published in 2015 documented that increasing adult neurogenesis (regardless of the modality) is sufficient enough to decrease anxiety. Therefore, it could be that CBD is an effective anxiolytic predominantly through mechanisms implicated in neurogenesis.
On multiple occasions I’ve taken orally formatted CBD as a test to determine whether it would lower my anxiety. The first occasion involved utilizing an extremely low dose which yielded a slightly noticeable psychological relaxation effect. The second time I administered CBD, I ingested a substantially greater dosage than the first occasion, but was also stressed prior to taking it.
A 2013 study conducted at the University of Haifa in Israel found that cannabinoid treatment after a traumatic experience may regulate the emotional response to the trauma and prevent stress-induced impairment. Cannabinoid treatment minimized the stress receptors in the basolateral amygdala (the nuclei that receives that majority of sensory information) and hippocampus (the part of the brain that is thought to be the center of emotion).

Human activities—including pollution, deforestation, overpopulation, poaching, warming oceans and extreme weather events tied to climate change—are predicted to drive so many mammals to extinction in the next five decades that nature will need somewhere between 3 to 7 million years to restore biodiversity levels to where it was before modern humans evolved, according to an alarming new analysis published Monday in the Proceedings of the National Academy of Sciences.
In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. For a more comprehensive look at these and other studies, visit our medical research and education page.
The nutrition and supplement industry—which includes CBD products—is almost wholly unregulated. “The concentrations in products are only approximate, and I don’t know how well they’re tracked,” Szaflarski says. Even if you could absolutely trust a product’s label—and many CBD manufacturers, aware of the current scrutiny on their industry, go to great lengths to assure consumers of the quality of their products—there aren’t a lot of concrete facts when it comes to the type or amount of CBD a person should take for a specific ailment or aim.
PPAR agonism: Agonism of PPARs (peroxisome proliferator activated receptors) may have a variety of benefits including: anticancer, neuroprotective (via removal of beta-amyloid plaques), and antipsychotic effects. Cannabidiol bolsters PPAR-alpha signaling and simultaneously decreases inflammation. Although PPAR agonism may not directly foster an anxiolytic effect, it cannot be ruled out as a potential synergistic contributor.
Colored impurities from the oil can be removed by adding activated charcoal to about one third to one half the weight or volume of the solvent containing the dissolved oil, mixing well, filtering, and evaporating the solvent. When decolorizing fatty oils, oil retention can be up to 50 wt % on bleaching earths and nearly 100 wt % on activated charcoal.
“THC”—the more-famous, high-inducing compound in cannabis—“works directly on the cannabinoid system, meaning it attaches to receptors and mimics some of our own internal endocannabinoids,” says Igor Grant, a professor and chair of psychiatry at the University of California, San Diego School of Medicine. But CBD’s interaction with the endocannabinoid system is subtler. “Normally, these endocannabinoid-signaling molecules are broken down by enzymes, and one thing CBD does is interfere with the actions of those enzymes.”
Just wanted to share with you that I have been ordering oil for my sister-in-law who had a Glioblastoma Multiform Brain Tumour. After surgery, 6 weeks of radiotherapy and 3 months of chemo (plus your amazing M10P treatments), my sister-in-law is tumour free as of today! Thank you so much for the service you provide. Feel free to share this story with other members who need a boost and some good news! Thanks again
A wealth of marketing material, blogs and anecdotes claim that cannabis oils can cure whatever ails you, even cancer. But the limited research doesn't suggest that cannabis oil should take the place of conventional medication, except for in two very rare forms of epilepsy (and even then, it's recommended only as a last-resort treatment). And, experts caution that because cannabis oil and other cannabis-based products are not regulated or tested for safety by the government or any third-party agency, it's difficult for consumers to know exactly what they're getting.
