Some studies—both preclinical animal and human clinical trials—suggest CBD could be used to help treat people who are dependent on opioids.

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.

Three well-vetted studies provide the basis of support for the FDA’s decision. In these trials, 516 patients with Lennox-Gastaut syndrome or Dravet syndrome received either Epidiolex or a placebo. Epidiolex, when taken along with other prescribed medications, decreased the frequency of participants’ seizures compared to the placebo.

When introduced topically, CBD oil doesn’t affect the systemic issue as it might if it were introduced directly into the bloodstream. Instead, topical CBD is more localized and treats pain in a certain area. Since it’s more direct, it may have a more pronounced effect.

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.

CBD research is growing, too. Here are nine ways studies suggest CBD oil could benefit your health.

CBD is advertised as providing relief for anxiety, depression and post-traumatic stress disorder. It is also marketed to promote sleep. Part of CBD’s popularity is that it purports to be “nonpsychoactive,” and that consumers can reap health benefits from the plant without the high (or the midnight pizza munchies).

A Scam?

A few drops of CBD oil in a mocha or smoothie are not likely to do anything, researchers contend. Doctors say another force may also be at play in people feeling good: the placebo effect. That’s when someone believes a drug is working and symptoms seem to improve.

This year, 1,090 people have contacted poison control centers about CBD, according to the American Association of Poison Control Centers. Over a third are estimated to have received medical attention, and 46 were admitted into a critical care unit, possibly because of exposure to other products, or drug interactions. In addition, concern over 318 animals poured into the American Society for the Prevention of Cruelty to Animals’ Animal Poison Control Center.

What are the claims?

However, a double-blind study found healthy volunteers administered CBD had little to no change in their emotional reaction to unpleasant images or words, compared to the placebo group. “If it’s a calming drug, it should change their responses to the stimuli,” said Harriet de Wit, co-author of the study and a professor in the University of Chicago’s department of psychiatry and behavioral neuroscience. “But it didn’t.”

CBD is widely touted as a panacea for a wide range of health problems and has been marketed as a dietary and “wellness” product (Russo 2017; Khalsa et al. 2020; Eisenstein 2019). CBD’s potential effects as an add-on therapy have been studied for social anxiety disorders, schizophrenia, non-motor symptoms in Parkinson’s disease, and substance use disorders (Bergamaschi et al. 2011; Crippa et al. 2019; McGuire et al. 2018; Millar et al. 2019; Prud’homme et al. 2015; Thiele et al. 2019; Leehey et al. 2020). However, the evidence of its effectiveness for indications other than drug-resistant pediatric epilepsy conditions remains very limited (Larsen and Shahinas 2020; Franco et al. 2020) and safety considerations such as drug-drug interactions associated with unsupervised use remain (Chesney et al. 2020; Freeman et al. 2019). Randomized controlled trials (RCTs) are limited in their rigorous design, population sample, and duration of observation making generalization of results and long-term data scarce. Therefore, real-world evidence (RWE) provides valuable insights and supplemental information about the use, safety, and effectiveness of CBD-based treatments (Graham et al. 2020).

Conclusion

The ANOVA showed main effects of visit, severity group (both ps < 0.001 with η 2 p = 0.04 and η 2 p = 0.4, respectively) and a significant group-by-visit interaction (F(2,620) = 34.47, p < 0.001; η 2 p = 0.1). Post hoc tests revealed a significant score difference between baseline and FUP1 and FUP2 (both ps < 0.01) but not between FUP1 and FUP2 (p = 0.85). Specifically, the scores of moderate/severe group decreased notably (t(110) = 9.56, p < 0.001) between baseline and FUP1 but the scores of the group with mild depression symptoms did not (p = 0.07) (Fig. 2c).

Mean scores and standard deviation (SD), as well as percentage, where appropriate are presented for each variable. All analyses were performed on each ESAS-r symptom separately through the data analytics software R v4.0.2. An initial analysis compared the overall ESAS-r scores between each visit no matter the severity of the group, and looked at the role of product group (CBD/THC:CBD vs CBD/CBD group) (between-factor). Tukey HSD post hoc test was used to confirm where the differences occurred between groups.
