The growing interest in CBD oil to potentially help with many different human health problems has resulted in some exciting new research over the last year. Not enough CBD oil research has been done yet to make absolute claims about what CBD oil can do.
But the positive results of each new study tell us further research is well worth it.
Looking forward to 2019, we’re expecting that there will be a sharp increase in U.S. research studies on hemp-derived CBD oil. The 2018 Farm Bill signed in December 2018 made hemp-derived CBD oil legal at the federal level in the United States. Legalization should increase funding for research that will give us more definitive insight.
Here are some of the new studies now underway and findings from others that have been published over the last year.
CBD Research for Alcohol Abuse Disorder
In November 2018, Dr. Esther Blessing and other researchers at the New York University School of Medicine joined forces with the National Institutes of Health to examine if CBD oil could be used to treat alcohol abuse in patients with post-traumatic stress disorder.
Researchers on this project say that this is the first attempt to examine the possibility of using CBD oil for treatment of both alcohol abuse and PTSD in humans. The study is still in the early stages. Based on results, this preliminary study will be expanded in a much larger clinical trial in the future.
CBD Research for PTSD
A paper regarding CBD oil for treating PTSD was published by the National Institute of Health last year. The authors noted that the most recent edition of the Diagnostic and Statistical Manual no longer categorizes PTSD as an anxiety disorder, but a reaction to external events or stresses.
About 10% of the population has PTSD at some point in their lives. Currently, it’s treated with anti-anxiety medications or antidepressants, which the researchers claim is ineffective. In this paper, the authors cited all the research that has been done to date.
They conclude that CBD therapy, especially when in the entourage effect with THC, can help alter reactions to triggers. They advise that more research should be done to produce a medication that includes it.
CBD Used in Conjunction With Clobazam for Refractory Epilepsy
Refractory epilepsy has been treated with pharmaceutical drugs for quite a while, but 1 out of 3 patients continues to have seizures while taking them. In a study in March 2018, researchers at Vanderbilt University Medical School examined the effectiveness of using artisanal CBD, together or separately with the drug clobazam, to treat epilepsy in children.
They found that 39 percent of the group taking only CBD had less than half as many seizures, about the same as the percentage of clobazam only users, and 10 percent had no seizures at all. Patients taking only clobazam showed similar results, but when the two were taken together, the percentage went up to 44 of patients having half as many seizures.
CBD oil users were able to take fewer meds and showed greater alertness and better verbal communication. These researchers highly recommend using artisanal CBD oil, which shows no significant side effects, to treat epilepsy in children.
Product Test for Dravet Syndrome
Another type of epilepsy affecting children is Dravet syndrome. Four medical institutions in Toronto performed a clinical trial last year to test a medication produced by a Canadian company, TIL‐TC150, for safety and appropriate dosage.
Nineteen children were given the medication for 20 weeks. This study concluded, like several others this year, that patients taking CBD oil had a definite improvement in the quality of life. The median reduction in seizures was 70%, and all patients had lower spikes on EEG tests.
Complex Motor Disorder
In August, 2018, researchers from Tel Aviv University School of Medicine and other organizations in Tel Aviv published results of a study of CBD oil therapy for children with Complex Motor Disorder. This disorder is usually related to problematic life issues, and it includes spastic movement, problems with sleep, pain, and dystonia, repetitive muscle contractions, twisting, or unusual static postures.
Twenty-five children were treated with two CBD oil blends containing different amounts of THC for 5 months. At the end of the study, they concluded that patients showed significant improvement, regardless of what amount of THC was in their dosage. And negative reactions were rare.
One finding similar to the Canadian Dravet study was that all the patients, even if they had some side effects, showed a clear improvement in the quality of life.
ALS Trial in Africa
Amyotrophic Lateral Sclerosis, also known as Lou Gehrig’s Disease, results in the death of motor neurons and the weakening of body functions. The CannTrust company in Ontario has partnered with Gold Coast University researchers to experiment with treating ALS patients with CBD oil preparations. This study is currently underway.
At this time, there is no cure for ALS, so this study may have huge implications for people with this debilitating disease.
Integumentary Wound Treatment
A Canadian research team in Toronto did a small study of using topical CBD oil to reduce the pain of skin wounds, which can result from abrasion, burns, injuries, or disease. Patients in the study relied on opioids to deal with excessive pain., a common problem for wound sufferers.
Three patients had a rare condition that caused painful sores to develop on their skin, which is part of the body’s integumentary system. All three reported significantly less pain after treatment, and took fewer opioids.
The researchers noted that cannabis had been used for this purpose for thousands of years.
Over the last year, researchers from many countries have looked into using CBD oil for a wide variety of different conditions. Some studies have been published and others are still in progress.
CBD advocates are hoping that these and additional studies of CBD oil will produce some groundbreaking research findings.
