CBD benefits include the following:
“CBD is not an intoxicating substance, whereas THC is a psychoactive that can get you high,” explains Dr. Jas Matharu-Daley, a physician and consultant for a brand that specializes in CBD production.
She adds, “[Another difference is that] CBD is derived from hemp and has been classified as a legal substance. Hemp has <0.3% THC. Conversely, cannabis plants such as marijuana are grown to have much higher levels of THC and are still illegal according to the FDA, although individual states vary as to their use.”
What Is Cannabidiol (CBD)?
Some common side effects when using CBD include drowsiness and sedation. This is also considered a benefit, but Dr. Jas Matharu-Daley, a physician and chief medical officer for a CBD brand, notes that the effects might be too strong if you’re also taking CBD with other sedating medications.
Because CBD supplements come in so many different forms—such as oils, gummies, tinctures, and vapors—the amount that’s actually absorbed can vary drastically. This, combined with each person, will ultimately affect which (if any) CBD side effects you might experience.
CBD might interfere with the other medications you take. Dr. Matharu-Daley says it’s important to talk to your doctor about whether CBD could affect your existing prescriptions.

CBD oil may reduce the risk of heart disease by alleviating hypertension (high blood pressure) in certain people, suggests a 2017 study in JCI Insight.
Here are a few tips to help you find the best CBD oil:

CBD’s exact mechanism of action is unclear. Unlike THC, CBD has a relatively low affinity for cannabinoid receptors in the brain. These are the molecules to which THC binds to elicit its psychoactive effects.
CBD oil comes as full-spectrum oils or in forms that contain CBD isolates. Unlike isolates, which contain CBD only, full-spectrum oils contain a variety of compounds found naturally in the cannabis plant, including proteins, flavonoids, terpenes, and chlorophyll. Alternative practitioners believe these compounds offer more substantial health benefits, although there is no clear evidence of this.
Oils and tinctures can be trickier because the packaging often states the amount of CBD in the entire bottle, not in a dropper. This calculator can help you figure out how many drops you need based on the strength of the product.
Enthusiasts rave about CBD’s potential to ease pain, reduce inflammation, relieve anxiety and promote sleep. However, there’s no conclusive research about just how much CBD a person needs to take in order to experience benefits.
When it comes to CBD in topical form (creams, lotions, and salves), you’ll probably see the total amount of CBD in the container listed on the label. You’ll then have to divide that total by the number of millimeters in the package to determine how much is in each milliliter. For example, if you have a 50 ml jar of salve that contains 200 mg of CBD, there’s 4 mg per ml. You should then use a metric measuring spoon to scoop out 7.5 ml to get a 30 mg dose of CBD.
3. Expect some trial and error
Figuring out how much CBD is in capsules or gummies is simple — just read the supplement facts section on the label. (If it says 10 mg of CBD per capsule, you’d take three capsules to get your 30 mg of CBD a day.)
CBD won’t get you high the way that cannabis with THC can, but it may still cause side effects. “The most common side effects are fatigue and lethargy, and in rare cases diarrhea,” says Dr. Patel, who notes that CBD that’s taken topically less commonly causes side effects. Topical CBD is best used to address pain in a single joint, rather than widespread pain, she adds.
Many factors, such as your body mass index (BMI), specific health condition(s) you have, medications you take, your health history, and the form of CBD you plan to use can influence how much CBD you may need to treat your symptoms. Although CBD is different than medical marijuana — which contains CBD as well as THC, an intoxicating ingredient — a doctor who’s well-versed in cannabis (marijuana) is probably the best person to help you help you sort it out.
“There are no standard doses for patients,” says Rachna Patel, DO, a physician who does consultations about medical marijuana and CBD and sells her own line of CBD products. “Ultimately, it’s trial and error, but you have to go about it in a methodical way.”
