Unlike THC, CBD has no psychoactive properties and will not give you a “high”. There is no evidence it has any abuse or dependence potential and to date, there is no evidence that it is associated with any serious side effects, according to the World Health Organization.
Many other studies, both on animals and humans, have overwhelmingly concluded that CBD has immunosuppressive and anti-inflammatory properties which may make it a good choice for some autoimmune conditions or inflammation-related complaints. 16
What is CBD?
Beneficial effects on anxiety after taking CBD were reported in an observational study where 21 patients out of 400 had anxiety. 8
Animal studies have shown that CBD has a positive effect on serotonin levels in the brain, and serotonin. Low levels of serotonin are thought to play a key role in mood as well as pain. 11
Conclusion: Topical CBD may help relieve inflammation and excessive sebum production associated with acne but more trials are needed.
Nerve pain arises from damaged, irritated, or dysfunctional nerves. When confused and damaged, the nerve will send mixed signals to the brain as well as other bodily systems. Everyone reacts differently to pain.
As per one report  , the short-use of CBD could help reduce the levels of spasticity multiple sclerosis patients experience. The results were modest. However, many people claimed a reduction in symptoms. Even so, more studies are needed to prove the usefulness of CBD in treating MS.
They also found that it could help treat people with tobacco and cannabis addiction. There is evidence of CBD reducing or blocking THC’s effect on the mind.
Psychotic Treatment Benefits
Additionally, a study published in Cellular Immunology in 2018  found that CBD may alter T-cells, which are part of the immune system, after spinal cord injury. It is believed that abnormal activities of T-cells are involved in Lupus as well.
However, how CBD works to relieve or modulate pain is still uncertain. The psychoactive influences of CBD could distract users from the pain and help them ease the pain for just a short while.
Test subjects who had used to use cannabis, and now they don’t have similar results but with fewer associations. This indicates that with time, the protective effect of cannabis fades.
Since excess insulin promotes the conversion of sugars into stored fat, leading to weight gain and obesity, the interplay between insulin regulation and cannabinoids could help in the prevention of obesity and type 2 diabetes in the future.
In another small study, 13 patients with type 2 diabetes who weren’t on insulin treatment were given both CBD and a placebo (in lieu of insulin). Researchers found CBD decreased their levels of resistin (which causes resistance to insulin, the protein that regulates sugar levels) and increased their levels of glucose-dependent insulinotropic peptide (a hormone that ensures a sufficient release of insulin from digested food) compared to their baselines before they started the test. These results suggest CBD could be a natural treatment for diabetes by helping the body regulate insulin-related hormone levels.
Preclinical and clinical studies show that CBD has antioxidant and anti-inflammatory properties. Researchers deduce these characteristics can provide significant neuroprotection, or protection against numerous pathological disorders.
In some instances, CBD can be used to treat epileptic seizures.
7. Ease Diabetic Complications
Meanwhile, at least one study in mice revealed CBD had effects similar to the antidepressant imipramine. Human trials are needed, though, to confirm whether CBD can induce this same antidepressant reaction in our bodies.
Several preclinical studies suggest CBD can produce beneficial effects against Parkinson’s disease, Alzheimer’s disease and multiple sclerosis. Huntington’s disease and cerebral ischemia were also tested, although significant positive results were not recorded. Further clinical studies are needed to confirm CBD’s benefits when used as a treatment for these disorders.
Four other human trials from 2012 to 2016 suggest CBD reduces PTSD symptoms, although some include THC, or tetrahydrocannabinol, the main mind-altering element in cannabis. When THC and CBD work together, they create what’s called an “entourage effect,” complementing each other’s benefits and potency. For example, taking the same dose of THC and CBD together tempers the “high” from THC, while just a little THC paired with more CBD enhances the effects of the CBD.
For starters, tests on human cells found that CBD helps reduce the effects of high glucose levels on other cells in the body, which typically precedes the development of diabetes and various complications. Researchers concluded that with further studies, CBD could have significant benefits when used in patients with diabetes, diabetic complications and plaque buildup in artery walls.
