But for children under age 21 it’s a different story. It’s also not clear if any amount of CBD is appropriate for children.

Again, yes and no, depending on where you live. In some states marijuana is legal for both recreational use and medical use. In other states, it’s legal only for medical use. And in some areas, it’s not legal at all.
The safest way to take CBD is orally, as a tablet, chewable, or tincture (a concentrated liquid typically administered with a dropper). Steer clear of any illegally sold synthetic CBD products, sometimes called “spice” or “bath salts.” These products have induced psychotic reactions in some people and pose a major health risk.
Common questions about medical cannabis
Evidence regarding CBD is still building. Now that some states have legalized recreational and medical use of marijuana products, including CBD, scientists are finding it easier to conduct research. More will be known in the next 5 to 10 years, including whether there are yet undiscovered problems associated with long-term use.
Yes, there is evidence that CBD works for some conditions, but certainly not all the conditions it is being promoted for these days. There’s no evidence, for example, that CBD cures cancer. There is moderate evidence that CBD can improve sleep disorders, fibromyalgia pain, muscle spasticity related to multiple sclerosis, and anxiety.
But many people still don’t really know what CBD is. Is it marijuana? Is it legal? Does it actually work? Is it safe?

Testing also shows that many products don’t contain what’s claimed on the label. For example, they may have less CBD than advertised. So, buyer beware.
CBD comes in many forms, including oils, extracts, capsules, patches, vapes, and topical preparations for use on skin. If you’re hoping to reduce inflammation and relieve muscle and joint pain, a topical CBD-infused oil, lotion or cream – or even a bath bomb — may be the best option. Alternatively, a CBC patch or a tincture or spray designed to be placed under the tongue allows CBD to directly enter the bloodstream.
Outside of the US, the prescription drug Sativex, which uses CBD as an active ingredient, is approved for muscle spasticity associated with multiple sclerosis and for cancer pain. Within the US, Epidiolex is approved for certain types of epilepsy and tuberous sclerosis.
The Farm Bill removed all hemp-derived products, including CBD, from the Controlled Substances Act, which criminalizes the possession of drugs. In essence, this means that CBD is legal if it comes from hemp, but not if it comes from cannabis (marijuana) – even though it is the exact same molecule. Currently, many people obtain CBD online without a medical marijuana license, which is legal in most states.
People taking high doses of CBD may show abnormalities in liver related blood tests. Many non-prescription drugs, such as acetaminophen (Tylenol), have this same effect. So, you should let your doctor know if you are regularly using CBD.
Is CBD safe?
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 be 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.
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, stop them altogether. Epidiolex, which contains CBD, is the first cannabis-derived medicine approved by the FDA for these conditions.
Cannabidiol (CBD) is often covered in the media, and you may see it touted as an add-in booster to your post-workout smoothie or morning coffee. You can even buy a CBD-infused sports bra. But what exactly is CBD? And why is it so popular?
How can CBD be taken?
Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer or COVID-19, which it is not. We need more research but CBD may prove to be a helpful, relatively non-toxic 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 currently is typically available as an unregulated supplement, it’s hard to know exactly what you are getting.
Animal studies, and self-reports or research in humans, suggest CBD may also help with:
