The tricky part is calculating the exact amount of CBD per milliliter of oil. Some tinctures have concentrations of 1,500 mg per 30 mL, while others have 3,000 mg per mL (or more).
It would be hard to overdose on CBD oil because human tolerance is very high. One study reported the toxic dose would be about 20,000 mg taken at one time.
There’s some evidence CBD interacts with seizure medicines like Onfi (clobazam) and boosts their concentration in the blood. More research is needed, though.
CBD oil might help relieve stress, anxiety, seizures, drug withdrawal, and nerve pain. But taking higher doses doesn't always mean they'll have a stronger impact. Also, many studies on CBD have been done on animals, so it's hard to tell if these same effects will apply to people.
What to Look For
Some experts suggest CBD may help treat cannabis and nicotine dependence, but more research is needed.
Unlike the THC that's in marijuana, CBD oil doesn't get you high. It contains a chemical called cannabidiol that might help relieve stress, anxiety, drug withdrawals, and nerve pain.
CBD is the short name for cannabidiol , one of the two chemicals in cannabis with the most health benefits. The other chemical is tetrahydrocannabinol (THC).
There are no guidelines for the proper use of CBD oil. CBD oil is usually taken by placing one or more drops under the tongue and holding it there for 30 to 60 seconds without swallowing.
More research on CBD has been emerging as it has gained popularity. Still, there are only a few clinical studies on the effects of CBD oil.
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.
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?
Is CBD safe?
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.
CBD is readily obtainable in most parts of the United States, though its exact legal status has been in flux. All 50 states have laws legalizing CBD with varying degrees of restriction. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. In 2018, the Farm Bill made hemp legal in the United States, making it virtually impossible to keep CBD illegal – that would be like making oranges legal, but keeping orange juice illegal.
Is cannabidiol legal?
CBD, or cannabidiol, is the second most prevalent active ingredient in cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, a cousin of marijuana, or manufactured in a laboratory. One of hundreds of components in marijuana, CBD does not cause a “high” by itself. 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.”
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.
