CBD oil has shown promise as a Treatment for both depression and anxiety, leading many who live with these disorders to become interested in this natural approach. The phytonutrient compounds found in cannabis oil, Cannabinoids, are all-natural and known to be super-effective for relaxing the mind, reducing stress and releasing pleasure hormones and a sense of calm.

Summary : Using CBD has been shown to reduce anxiety and depression in both human and animal studies.

Scientists have discovered that certain components of marijuana, including CBD, are responsible for its Pain-relieving effects. Several studies show that CBD provides relief for chronic pain stemming from arthritis, multiple sclerosis, and other conditions. The body’s endocannabinoid system is involved in regulating your emotions, motor control, immune system, and pain response. When the body ingests CBD, it affects the way your body perceives and responds to pain. Cannabinoids, CBC, CBD and CBG are known to be potent and powerful analgesic pain-killers, and anti-inflammatories. 

Summary: CBD, especially in combination with THC, may be effective in reducing pain associated with diseases like multiple sclerosis and rheumatoid arthritis.

Short answer is Yes. CBD was shown to consistently improve sleep quality over a period of 5 months—in the absence of any pharmaceutical drugs. A once daily 160 mg CBD treatment enabled the individual to sleep through the night and experience better quality sleep, increase in total sleep time and less frequent awakenings, with less overall anxiety during the day.

This is one of the best benefits because great sleep is essential! In healthy volunteers with regular sleep cycle, 600 mg of CBD induced sedative effects whereas in subjects with insomnia, acute use of CBD (160 mg/day) was associated with an increase in total sleep time and less frequent awakenings.

Inflammation and oxidative stress are intimately involved in the genesis of many human diseases. CBD would seem to be a promising starting point for further drug development given its anti-oxidant (although relatively modest) and anti-inflammatory actions on immune cells. The research shows Manipulation of endocannabinoids by use of cannabinoids in vivo can constitute a potent treatment modality against inflammatory disorders.

CBD and THC are capable of helping treat people suffering from PTSD by improving the endocannabinoid system’s mediation of essential functions including memory consolidation and retrieval. By activating CB1 and CB2 receptors located throughout this core system, cannabinoids could prompt the system to produce neurotransmitters that helps promote happiness, pleasure, and memory.
These cannabinoids play a critical role in assisting PTSD cases by preventing the retrieval of the underlying trauma, effectively preventing traumatic memories and nightmares, while also helping attain emotional wellbeing. This has made it a popular treatment for PTSD patients, of which many are combat veterans.

Researchers believe that CBD’s ability to act on the endocannabinoid system and other brain signaling systems may provide benefits for those with neurological disorders.
In fact, one of the most studied uses for CBD is in treating neurological disorders like epilepsy. In numerous studies, CBD was able to reduce seizures and in some cases stop them altogether.

Cannabis contains more than 100 pharmacologically active compounds (cannabinoids), with the most studied compounds being the tetrahydrocannabinol (THC) and cannabidiol (CBD). Both have tested for modulating spasticity associated with MS, as well as managing seizures, inflammation, pain, anxiety, and other conditions.

Several studies have shown that regular cannabis users have a lower body mass index, smaller waist circumferences, and reduced risk of diabetes and obesity. For the most part, research investigating the relationship between marijuana use and diabetes has shown promising results.

Of the studies conducted, they fall into two categories: prevention and treatment. The correlation between marijuana and diabetes prevention is largely inconclusive. A 2012 study published in BMJ Open found a 58% reduced risk of developing diabetes associated with marijuana use. A larger 2016 study published in the Journal of Diabetes Research found no correlation between cannabis use and diabetes.

CBD may also be instrumental in helping people overcome nicotine or opioid addiction, by alleviating the symptoms of withdrawal.
One study of smokers who wanted to quit smoking gave participants an inhaler of either CBD or a placebo. Over the course of one week, they were told to use the inhaler whenever they felt the urge to smoke. At the end of the week, those with the placebo inhaler smoked the same amount of cigarettes as they had before the study. Participants with the CBD inhaler, however, reduced the total number of cigarettes they smoked by 40%.

In addition to their illness, cancer patients often live with several uncomfortable symptoms, like pain, depression, and sleep issues. Worse, the treatment for cancer often results in chemotherapy-induced nausea and vomiting. CBD can relieve all of these cancer symptoms.
Not all cancer patients adequately respond to traditional pain medication like opioids. Of the ones who do, they may develop an addiction to the drugs. CBD provides an alternative treatment that is non-habit forming and even more effective, according to the research. One study that CBD reduced pain 30% more than traditional medication or THC alone.
