The eCB system regulates diverse physiological functions, including caloric energy balance and immune function [28]. The eCB system is also integral to regulation of emotional behavior, being essential to forms of synaptic plasticity that determine learning and response to emotionally salient, particularly highly aversive events [29, 30]. Activation of CB1Rs produces anxiolytic effects in various models of unconditioned fear, relevant to multiple anxiety disorder symptom domains (reviewed in [30–33]). Regarding conditioned fear, the effect of CB1R activation is complex: CB1R activation may enhance or reduce fear expression, depending on brain locus and the eCB ligand [34]; however, CB1R activation potently enhances fear extinction [35], and can prevent fear reconsolidation. Genetic manipulations that impede CB1R activation are anxiogenic [35], and individuals with eCB system gene polymorphisms that reduce eCB tone—for example, FAAH gene polymorphisms—exhibit physiological, psychological, and neuroimaging features consistent with impaired fear regulation [36]. Reduction of AEA–CB1R signaling in the amygdala mediates the anxiogenic effects of corticotropin-releasing hormone [37], and CB1R activation is essential to negative feedback of the neuroendocrine stress response, and protects against the adverse effects of chronic stress [38, 39]. Finally, chronic stress impairs eCB signaling in the hippocampus and amygdala, leading to anxiety [40, 41], and people with PTSD show elevated CB1R availability and reduced peripheral AEA, suggestive of reduced eCB tone [42].
Cannabinoid therapy is connected to the part of the biological matrix where body and brain meet. Since CBD (cannabidiol) and other compounds in cannabis are so similar to the chemicals created by our own bodies, they are integrated better than many synthetic drugs. According to Bradley E. Alger, a leading scientist in the study of endocannabinoids with a PhD from Harvard in experimental psychology, “With complex actions in our immune system, nervous system, and virtually all of the body’s organs, the endocannabinoids are literally a bridge between body and mind. By understanding this system, we begin to see a mechanism that could connect brain activity and states of physical health and disease.”[175]

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 [20].

I think she will end up,, by accident, killing herself. It is so, so sad. She had tried AA. That took us years of pleading with her to attend some meetings. They seemed to help a little bit but she has stopped going. I think she realises that there are people there just like her who have managed to quit and somehow she doesn’t seem to want to be part of that. She just keeps making up excuses or lies about why she won’t go back.

A study performed at the Italian Piemonte University and published in 2008 implied that all cannabinoids help the immune system to fight bacteria. Especially potent are five cannabinoids (including CBD), with the study focusing on antibiotic-resistant strains of the Staphylococcus Aureus, a relevant example of the antibiotics abuse the last few decades have witnessed.
The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, D.O., a cannabis doctor in Boulder, CO.
The cannabis plant is filled with hundreds of different compounds, several of which have been studied for decades for their therapeutic benefits. The cannabis compounds that have captured the most scientific interest are known as cannabinoids. Cannabinoids are now used in treatment for a broad—and growing—range of conditions and symptoms, from sleep and pain, to anxiety and inflammation, to Parkinson’s disease and cancer.
Later, Queen Victoria’s physician and one of the world’s leading doctors of that era, Sir Russell Reynolds, prescribed medicinal cannabis for the Queen’s menstrual cramps, for which CBD still works fantastically today. When writing about medical marijuana in the first edition of the British medical journal The Lancet, Reynolds proclaimed that cannabis is “one of the most valuable medicines we possess.” Another widely hailed physician at the time, Sir William Osler, used CBD for migraines with excellent results.
I used a “cbd tincture 250mg”. After about 3 weeks I started passing blood and protein in urine. I stopped and it cleared up. A couple weeks later I decided to try again and within 3 days it happened again. Could this be due to the type of oil I used or might I have the same problem with any oil I try? It was helping my hip pain and crohns. Thanks!
So am I to assume, due to no response/deleted comment that my simple question was too difficult to answer? With all the technical & correct information you have on you GREAT website, can someone (?) not simply correct or acknowledge the FACT the your NOT using nano-particle size product? I am truly interesting (for my wife) in CBD, have done my research, and I love working with numbers which is why if found this discrepancy. Comments welcome, but avoidance is disturbing.
