Medical marijuana and legalization have been hot topics recently. Cannabidiol (CBD) is one of at least 113 active cannabinoids identified in cannabis.

 

  • Tetrahydrocannabinol (THC)  is the principal psychoactive cannabinoid in cannabis.
  • CBD is a major phytocannabinoid, accounting for up to 40% of the plant’s extract. Cannabinoids are considered to have a wide scope of potential medical applications.

 

This is due to clinical reports showing the lack of side effects and non-interference with learning and psychological functions. They also have been shown have antidepressant, anxiolytic, and neuroprotective effects.

The Endocannabinoid System

The endocannabinoid (eCB) system controls emotional responses, behavioral reactivity to context, and social interaction.Enhancement of endocannabinoid signaling can enhance serotonergic and noradrenergic transmission, increase cellular plasticity and neurotrophin expression within the hippocampus, and dampen activity within the neuroendocrine stress axis.

Benefits

 

1.Promotes Neurogenesis

livinghealthyallday.com

Recent studies indicate that a natural cannabinoid of cannabis, specifically CBD, increases adult neurogenesis.

Cannabidiol reduced Aβ-induced neuroinflammation and promotes hippocampal neurogenesis through PPARγ involvement.

Repeated administration of CBD increased hippocampal progenitor proliferation and neurogenesis in wild-type mice.

In mice, chronic THC exposure increased BDNF in the hippocampus, but not the frontal lobe.

 

2.May Help With Alzheimer’s

Activation of both CB1 and CB2 receptors have beneficial effects in Alzheimer experimental models by reducing the harmful β-amyloid peptide action and tau phosphorylation, as well as by promoting the brain’s intrinsic repair mechanisms.

CBD inactivated amyloid precursor protein (via activation of PPARγ). Although, THC is a considerably superior inhibitor of Aβ aggregation.

CBD may have potential as a preventative treatment for AD with a particular relevance for symptoms of social withdrawal and facial recognition. There have been studies showing no efficacy in AD too.

 

3.Protects the Brain

livinghealthyallday.comAcute and chronic administration of cannabidiol increases mitochondrial complex and creatine kinase activity in the rat brain.

CBD produced significantly better intracranial pressure/cerebral perfusion pressure control without jeopardizing blood pressure.

CBD protects against the vascular damage caused by a high glucose environment, inflammation or the induction of type 2 diabetes in animal models and reduces the vascular hyperpermeability associated with such environments.

 

4. Helps With Anxiety

CBD was shown to reduce anxiety in patients with social anxiety disorder (by inducing activity in limbic and paralimbic brain areas).

It also helped with public speaking induced anxiety.

CBD has anxiolytic and possibly antipsychotic properties. CBD was associated with activation in right temporal cortex during auditory processing. During visual processing, CBD increased activation relative to placebo in the right occipital lobe, with maxima in the middle and inferior occipital gyri, the lingual gyrus, and cuneus.

 

5. Helps with Stress

Proper endocannabinoid signaling modulates the HPA axis.  Stress-induced downregulation of hippocampal eCB signaling.

What is interesting (just like microdosing yourself to stress) is that repeated exposure to the same stress can sensitize CB1 receptor signaling, resulting in dampening of the stress response. R What is interesting (just like microdosing yourself to stress) is that repeated exposure to the same stress can sensitize CB1 receptor signaling, resulting in dampening of the stress response.

6. May Help with Depression

The EC system is suggested to be dysfunctional in mood and related disorders. R In comparison to placebo, CBD improved emotional facial affect recognition at 60% emotional intensity. R CBD induces antidepressant-like effects comparable to those of imipramine, an anti-depressant. R Also, it exhibited an anti-anxiety and antidepressant effects in animal models.  Endocannabinoids play a role in blood pressure regulation in depressives with higher blood pressure.

 

7. Has Anti-Inflammatory Properties

livinghealthyallday.comCB2 receptors are expressed in several types of inflammatory cells and immunocompetent cells. R Activating CB2 receptors inhibit the release of proinflammatory factors.

CBD treatment resulted in an increase in BDNF expression in the hippocampus and decreased levels of proinflammatory cytokines in the hippocampus (TNF-α) and prefrontal cortex (IL-6).

 

8. Helps the Liver

Ischemia/reperfusion (I/R) is a pivotal mechanism of liver damage after liver transplantation or hepatic surgery. CBD significantly reduced the extent of liver inflammation, oxidative/nitrative stress, and cell death.  Myeloid-derived suppressor cells (MDSCs) are one of the main regulatory cells of the immune system.

While MDSCs induced by CBD in liver consisted of granulocytic and monocytic subsets at a ratio of ∼2∶1, the monocytic MDSCs were more immunosuppressive compared to granulocytic MDSCs, so they may help in certain autoimmune conditions.

Cannabidiol restores liver function, normalizes 5-HT levels and improves brain pathology in accordance with normalization of brain function.

9. Helps Glaucoma

In glaucoma, the increased release of glutamate is the major cause of retinal ganglion cell death. Cannabinoids have been demonstrated to protect neuron cultures from glutamate-induced death.  Although CBD did not reduce intraocular pressure.

10. Promotes and Healthy Skeletal System

livinghealthyallday.com

The endocannabinoid system has been implicated in the regulation of bone metabolism. Cannabinoid ligands regulate bone mass.

CB1 and CB2 receptors have a protective effect against age-dependent bone loss in mice.

Administration of CBD led to improvement in fracture healing.

In humans, polymorphisms in CNR2, the gene encoding CB2, are strongly associated with postmenopausal osteoporosis.

Therefore CB2 agonists (like CBD) enhances endocortical osteoblast number helping osteoperosis.

 

 

11. Alleviates Sleep Problems

Recent studies find that at least 18% of adults report receiving insufficient sleep. Adults with chronic sleep loss often report excess mental distress.

CBD may help with insomnia as it significantly decreases subjective anxiety and increased mental sedation.

REM sleep behavior disorder (RBD) is a parasomnia characterized by the loss of muscle atonia during REM sleep associated with nightmares and active behavior during dreaming.  In a small study (of 4), CBD is able to control the symptoms of RBD.

12. Has Anti-Histamine Properties

livinghealthyallday.com

CB1 receptors are present in mast cells. Activated CB1 receptors present in mast cells suppresses degranulation (by inducing sustained cAMP elevation).

Activation of CB2 receptors (like taking CBD) attenuates NGF-induced mast cell degranulation.

13. Reduces Chronic Pain

livinghealthyallday.com

 

 

Sativex (a combination of CBD and THC in equal parts) is approved in Canada for treatment of central neuropathic pain in multiple sclerosis and intractable cancer pain.

 

In patients with GlyR dysfunction, cannabinoids may be effective for treatment of chronic pain.

 

 

 

 

 

 

14. Reduces Dyskinesia

Dyskinesia is a movement disorder that is characterized by involuntary muscle movements, including movements similar to tics or chorea and diminished voluntary movements.  CBD decreases the amounts of key enzymes that can cause dyskensia.  In mice, when a TRPV-1 was combined with CBD, it reduced the symptoms of dyskensia.

15. Treats Neuropathy

There is mounting evidence for therapeutic use of CBD in human neuropathic pain conditions.

CBD helps with neuropathic pain. It also has been shown to help with neuropathic pain in Multiple Sclerosis.

16.Reduces Acne

Escalated sebum fabrication is seen with an unattractive look and adds to the growth of acne.  CBD cream reduced skin sebum and erythema content.  Activation of the endocannabinoid system controls the proper and well-balanced proliferation, differentiation and survival, as well as immune competence and/or tolerance, of skin cells.

Therefore CBD may be an effective treatment for  multiple pathological conditions and diseases of the skin (ie acne, seborrhea, allergic dermatitis, itch and pain, psoriasis, hair growth disorders, systemic sclerosis and cancer).

17. Plays a role in addiction

Drug addiction is a chronically relapsing disorder characterized by the compulsive desire to use drugs and a loss of control over consumption.

Medical cannabis laws are associated with significantly lower state-level opioid overdose mortality rates.

CBD may have therapeutic properties on opioid, cocaine, and psychostimulant addiction:

 

  • CBD reduced cigarette consumption in tobacco smokers.
  • It reduced nicotine withdrawal.
  • CBD inhibited the reward-facilitating effect of morphine.
  • It reduced the amount of times rats self-administered heroin.
  • CBD prevented neurotoxicity in rats from alcohol binging.
  • CBD was an effective treatment of cannabis withdrawal syndrome (of THC).

 

Interestingly, CB1 antagonism prevented neurochemical and behavioural deficits induced by chronic PCP.

 

  • CBD can attenuate both behavioral and dopaminergic neuronal correlates of mesolimbic dopaminergic sensitization, via a direct interaction with mTOR/p70S6 kinase signaling within the mesolimbic pathway

 

18. May prevent Mad Cow Disease

Mad cow disease (bovine spongiform encephalopathy) is a fatal neurodegenerative disease in cattle that causes a spongy degeneration of the brain and spinal cord.

The disease may be most easily transmitted to humans by eating food contaminated with the brain, spinal cord or digestive tract of infected carcasses.livinghealthyallday.com

However, the infectious agent, although most highly concentrated in nervous tissue, can be found in virtually all tissues throughout the body, including blood.

CBD prevented prion accumulation and protects neurons against prion toxicity (by inhibiting the neurotoxic effects of PrPres and affected PrPres-induced microglial cell migration in a concentration-dependent manner.)

19. May help with ALS

A number of abnormal physiological processes occur simultaneously in ALS.

Cannabis appears to have activity in all of those areas.

Cannabis has powerful antioxidative, anti-inflammatory, and neuroprotective effects (prolonged neuronal cell survival, delayed onset, and slower progression of the disease.

Cannabis also has properties applicable to symptom management of ALS, including analgesia, muscle relaxation, bronchodilation, saliva reduction, appetite stimulation, and sleep induction.

20. Plays a Role in Anorexia

Anorexia nervosa (AN) has the highest mortality rate between psychiatric disorders.

AN has been associated with different alleles of the CB1 gene. CBD effects leptin and ghrelin.

Endocannabinoids effect the liver’s ability for: secretion of hormones regulating appetite and satiety (leptin, adiponectin), lipogenesis, adipogenesis, obesity, and insulin resistance via CB1.

In AN short-term weight gain is associated with a disproportionately increased leptin secretion. Ghrelin acts as a natural antagonist to leptin.

Circulating ghrelin levels are increased in illness-induced anorexia. Ghrelin and endocannabinoids exert orexigenic effects which may facilitate nutritional restoration.

The effect of cannabinoids appears to be bi-phasic, as they can stimulate as well as inhibit food intake, depending on the preparation and the dose used.

 

21. Has Anti-Bacterial Properties

All 5 major cannabinoids inhibited:livinghealthyallday.com

  • MRSA
  • Staphylocci
  • Streptococci

 

 

 

22. May Help Atherosclerosis

Cannabinoids (mostly THC) was shown to inhibit disease progression through pleiotropic effects on inflammatory cells.

Cannabidiol has an immunomodulating effect that helps lessen the progression of atherosclerosis induced by high glucose level.

Activation of CB2 receptors inhibited atherosclerotic plaque progression in mice.

23. May Help Treat Arthritis

In animal models, CBD treatment effectively blocked progression of arthritis.

Also, because of its anti-inflammatory properties, CBD may also help with rheumatoid arthritis.

24. May Prevent Asthma

Asthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways. R Both CB1 and CB2 receptors are involved in lung protection. R

The activation of CB1 receptors on bronchial nerve endings has bronchodilator effects by acting on the airway smooth muscle and may be beneficial in airway hyperreactivity and asthma.

Technical:

  • CBD was able to decrease the serum levels of IL-4, IL-5, IL-13, IL-6,, and TNF-αexcept for IL-10

25. May Help With Autism

Autism spectrum disorder (ASD) is a complex behavioral condition with onset during early childhood and a lifelong course in the vast majority of cases.

It is characterized by deficits in communication and social interaction, as well as by stereotypic behaviors, restricted patterns of interest, and abnormal sensory issues.

Altered neurodevelopment during early pregnancy represents the neuropathological cause of ASD.

Alterations in this eCB system may contribute to the autistic phenotype.

 

26. Has Anti-Nausea Effects

Cannabis has long been known to limit or prevent nausea and vomiting from a variety of causes.

Technical:

  • CBD produced its anti-emetic/anti-nausea effects by indirect activation of the somatodendritic 5-HT(1A) autoreceptors in the dorsal raphe nucleus.
  • Activation of these autoreceptors reduces the release of 5-HT in terminal forebrain regions.

 

27. May Help with Bipolar Disorder

This is controversial, but one of my friends with bipolar disorder benefits from marijuana. I believe it is from the effect on the cannabinoid system.

Anyway, THC and CBD may help by exerting sedative, hypnotic, anxiolytic, antidepressant, antipsychotic and anticonvulsant effects.

 

28. Helps with Irritable Bowel Syndrome

Enteric glial cells (EGC) actively mediate acute and chronic inflammation in the gut.

GC proliferate and release neurotrophins, growth factors, and pro-inflammatory cytokines.

They can amplify the immune response, representing a very important link between the nervous and immune systems in the intestine.

CBD can control activation of enteric glial cells.

Technical:

  • CBD inhibits 5-HT3 receptor.
  • CBD reduced the expression of S100B and iNOS proteins.
  • Mediated via the selective PPAR-gamma

Marijuana (including CBD and THC) use is also associated with lower levels of fasting insulin and HOMA-IR (homeostasis model assessment of insulin resistance), as well as a smaller waist circumference.

livinghealthyallday.com

In both humans and mice, blocking CB1 can increase insulin sensitivity.

Oxidative stress and inflammation play critical roles in the development of diabetes and its complications.

CBD reduces ROS, neurotoxicity, inflammation, and BRB breakdown in diabetic animals (by inhibiting p38 MAPK).

It also lowered the incidence of diabetes in young non-obese diabetes-prone female mice.

CBD can also be used to retard β-cell damage in type 1 diabetes.

THC may serve a protective role against hyperlipidemia and hyperglycemia in diabetic.

There is an increased risk of acute pancreatitis (AP) among type 2 diabetic patients.

CBD significantly improved the pathological changes of mice with AP.

Technical:

  • CBD attenuated myocardial dysfunction, cardiac fibrosis, oxidative/nitrative stress, inflammation, cell death, and interrelated signaling pathways.
  • IFN-gamma, IL-12 and TNF-alpha was lowered, IL-4 and IL-10 was increased.
  • CBD also attenuated the high glucose-induced increased reactive oxygen species generation, NFκB activation, and cell death in primary human cardiomyocytes.
  • Cannabidiol and O-1602 showed anti-inflammatory effects in mice with AP and improved the expression of GPR55 in the pancreatic tissue as well.

 

32. It Plays a Role in Certain Endocrine Systems

The hypothalamo-neurohypophyseal system plays a role in homeostasis under a variety of stress conditions, including endotoxemia.

CB1 receptor is expressed in the hypothalamus and the pituitary gland, and its activation is known to modulate all the endocrine hypothalamic-peripheral endocrine axes.

The endocannabinoid system modulates rewarding properties of food by acting at specific mesolimbic areas in the brain.

ECS dysregulation has been associated with the development of dyslipidemia, glucose intolerance and obesity.

Technical:

  • In the hypothalamus, CB1 receptor and endocannabinoids are integrated components of the networks controlling appetite and food intake
  • Pathological overactivation of the ECS contributes to weight gain, reduced sensitivity to insulin and glucose intolerance, and blockade of CB1 receptors reduces body weight through increased secretion of anorectic signals and improved insulin sensitivity.

33. Protects the Heart

CBD is beneficial in the cardiovascular system.

CBD has been shown to be anti-arrhythmic in animal models.

It protects against the vascular damage caused by a high glucose environment, inflammation or the induction of type 2 diabetes in animal models.

35. May Help with Seizures and Epilepsy

Severe childhood epilepsies are characterized by frequent seizures, neurodevelopmental delays, and impaired quality of life.

Epilepsy is the most common neurological disorder, with over 50 million people worldwide affected.

Endocannabinoids and their receptors are altered by epileptic seizures.

Studies suggest using Cannabidivarin may be effective for treatment of epilepsy.

livinghealthyallday.com

In one study, 4 of the 8 CBD subjects remained almost free of convulsive crises throughout the experiment, 3 patients demonstrated partial improvement in their clinical condition, and was ineffective in 1 patient.

In another study, 7 out of the eight epileptics receiving CBD had improvement of their disease state at 200-300mg/day.

Although in another study, CBD did nothing at doses of 200-300mg/day for epilepsy.

So, CBD may only be effective in 3 types of epilepsy: grand mal, cortical focal, and complex partial seizures.

Technical:

  • Cannabidivarin (CBDV) and cannabidiol (CBD) exert anticonvulsant activity in vivo and produce TRPV1-mediated intracellular calcium elevation in vitro.
  • CBDV antiepileptiform effects in the Mg2+-free model are not uniquely mediated via activation of TRPV1.
  • There were correlations between reductions of seizure severity and mRNA expression of Fos, Egr1, Arc, Ccl4 and BDNF in the majority of brain regions in the CBDV+PTZ treated group.

 

36. Plays a Role in Motion Sickness
