Conclusion: CBD is unlikely to be effective by itself for nausea and vomiting. The combination of THC and CBD does seem to be effective for nausea and vomiting.
Conclusion: CBD does not appear to interfere with sleep and may help people sleep better.
Animal studies have shown that CBD has anti-inflammatory effects and works on the endocannabinoid and pain-sensing systems to relieve pain.
9. Nausea and vomiting
In addition, more trials are needed to investigate its use for numerous other conditions, such as muscle-spasticity in multiple sclerosis, Alzheimer’s disease, substance-abuse treatment, and diabetes protection.
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
We look at nine medical conditions where CBD may be, or, has already proven to be, beneficial.
Conclusion: Topical CBD may be beneficial at relieving arthritis but no high-quality human studies prove this.
Yes and no. Legality is a complex topic because it depends on where your CBD product comes from, says Capano: “CBD is legal at the federal level only if it’s derived from U.S.-grown hemp that has a license and permit under the Farm Bill; if yours is flown in from overseas or is derived from the marijuana plant, it’s technically not federally legal,” she explains. (A cannabis plant is either hemp or marijuana, depending on how much THC is in it. Hemp has 0.3 percent THC or less by weight when harvested, while marijuana has more than 0.3 percent THC by weight and is still federally illegal.)
While all that combines to mean CBD has magical pain-slashing properties for certain aches, it’s not ideal for every kind. It’s a great, effective therapeutic option for chronic pain and pain prevention (e.g. frequent headaches, ongoing back pain that’s lasted more than a week), says Capano. “But if you have an acute injury, like a broken bone, CBD is not going to be a substitute for morphine in the hospital; those really strong narcotic painkillers have their place.”
Is CBD legal?
You should also ask if the brand does third-party testing, what level of actives are in the product, whether it contains any microbial contaminants or pesticides. Not only should any reputable company make this info readily available, but they also should include a batch number with every product, so you can see a lab analysis. Don’t be afraid to push for all these details, says Capano: “The more we demand transparency that as consumers, the better the industry will get.”
The bad news: Your body metabolizes CBD through a pathway in your liver known as CYP 450, where enzymes break up potentially harmful compounds—and it’s the same pathway in your liver that metabolizes most common prescriptions and over-the-counter medicines, says Capano.
If you’re in a big city, you’ve likely seen CBD all over—from chic pop-up shops to your corner bodega. If you’re in a small town, you can probably find it in a brick-and-mortar shop too, as lots of small, independent pharmacies are carrying CBD products now. But if you do have trouble tracking it down in person, you can easily order online and have it shipped to any state (since U.S.-grown CBD is legal nationwide per the Farm Bill). But keep in mind: “There are so many online retailers, you have to do your homework,” says Capano.
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."

How is cannabidiol different from marijuana?
Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.
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.
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So, you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.
