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.
Amyotrophic lateral sclerosis (ALS) is a disease that causes nerve cells in the brain and spinal cord to deteriorate, resulting in loss of muscle control that worsens over time. It’s not yet understood exactly why ALS occurs, although it can be hereditary in some cases. There’s no known cure, and there are only two FDA-approved medications to help treat ALS symptoms.
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.

Arthritis involves the deterioration of the tissues in and around your joints. There are several types of arthritis, and symptoms include pain, stiffness and loss of motion. Arthritis treatment usually targets pain relief and improved joint function.
CBD’s ability to calm is perhaps its most popular effect and the reason its use is so widespread. A 2017 study in the Brazilian Journal of Psychiatry tested the anxiety levels of 57 men in a simulated public speaking test. Some received a placebo while others received either 150 milligrams, 300 milligrams or 600 milligrams of CBD before their speeches. Those who received 300 milligrams of CBD experienced significantly reduced anxiety during the test compared to those who received the placebo. Interestingly, participants who received either 150 or 600 milligrams of CBD experienced more anxiety during the test than the 300 milligrams group.
Some studies—both preclinical animal and human clinical trials—suggest CBD could be used to help treat people who are dependent on opioids.
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.
Even though humans have been using cannabis for thousands of years, the products available today are not the cannabis that has traditionally been consumed. After cannabis was prohibited at the federal level in 1970 by the US Controlled Substances Act, illicit growers were incentivized to breed strains that had higher amounts of THC, so they could increase their profits without needing larger growing spaces. What they didn’t know was that by driving up THC content, they were dramatically reducing the CBD content. In 1995, after decades of surreptitious breeding, the ratio of THC to CBD was
Right now, the most significant side effect of CBD we’ve seen is its interaction with other drugs. CBD impacts how the human liver breaks down other drugs, which means it can elevate the blood levels of other prescription medications that people are taking — and thus increase the risk of experiencing their side effects. And women who are pregnant or who are expecting to be should be aware of this: We don’t know if CBD is safe for the fetus during pregnancy.
Is CBD a cure-all — or snake oil? Jeffrey Chen, executive director of the UCLA Cannabis Research Initiative, explains the science behind the cannabis product.
Due to decades of research restrictions in the US and growers’ focus on THC, there are very few human studies that look at CBD and its effects. The strongest evidence we have is that CBD can reduce the frequency of seizures in certain rare pediatric disorders — so much that a CBD-based drug called Epidiolex was FDA-approved in 2018 for this purpose. There is also preliminary human data from small clinical trials with dozens of subjects that suggests CBD may have the potential to be used for conditions like anxiety, schizophrenia, opioid addiction, and Parkinson’s disease. But please note that the participants in these studies generally received several hundreds of milligrams of CBD a day, meaning the 5mg to 25mg of CBD per serving in popular CBD products may likely be inadequate. And even if you took dozens of servings to reach the dosage used in these clinical trials, there is still no guarantee of benefit because of how preliminary these findings are.
15:1, and by 2014 the ratio had jumped to
So where does this leave us? Unfortunately, outside of certain rare pediatric seizure disorders, we scientists do not have solid data on whether CBD can truly help the conditions that consumers are flocking to it for — conditions like insomnia, depression and pain. And even if it did, we still need to figure out the right dose and delivery form. Plus, CBD is not without side effects. Here’s the advice that I give to my friends and family: If you’re using CBD (or thinking about using it), please research products and talk to your doctor so they can monitor you for side effects and interactions with any other drugs you take.
CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.
CBD has been touted for a wide variety of health issues, but the strongest scientific evidence is for its effectiveness in treating some of the cruelest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications. In numerous studies, CBD was able to reduce the number of seizures, and, in some cases, it was able to stop them altogether. Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. Recently the FDA approved the first ever cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.
The evidence for cannabidiol health benefits
Cannabidiol (CBD) has been recently covered in the media, and you may have even seen it as an add-in booster to your post-workout smoothie or morning coffee. What exactly is CBD? Why is it suddenly so popular?
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a "high." According to a report from the World Health Organization, "In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD."
