Cannabidiol (CBD) is a chemical in the Cannabis sativa plant, also known as cannabis or hemp. One specific form of CBD is approved as a drug in the U.S. for seizure.
Over 80 chemicals, known as cannabinoids, have been found in the Cannabis sativa plant. Delta-9-tetrahydrocannabinol (THC) is the most famous ingredient in cannabis. But CBD is obtained from hemp, a form of the Cannabis sativa plant that only contains small amounts of THC. CBD seems to have effects on some chemicals in the brain, but these are different than the effects of THC.
A prescription form of CBD is used for seizure disorder (epilepsy). CBD is also used for anxiety, pain, a muscle disorder called dystonia, Parkinson disease, Crohn disease, and many other conditions, but there is no good scientific evidence to support these uses.
Laws passed in 2018 made it legal to sell hemp and hemp products in the US. But that doesn’t mean that all CBD products made from hemp are legal. Since CBD is an approved prescription drug, it can’t be legally included in foods or dietary supplements. CBD can only be included in “cosmetic” products. But there are still CBD products on the market that are labeled as dietary supplements. The amount of CBD contained in these products is not always the same as what is stated on the label.
What is it used for?
There is interest in using CBD for a number of other purposes, but there isn’t enough reliable information to say whether it might be helpful for these uses.
When taken by mouth: CBD is possibly safe to take in appropriate doses. Doses of up to 200 mg daily have been used safely for up to 13 weeks. With the guidance of a healthcare provider, a specific prescription CBD product (Epidiolex) has been used at higher doses.
CBD can cause some side effects, such as dry mouth, low blood pressure, light headedness, and drowsiness. Signs of liver injury have also been reported with high doses of the prescription form of CBD, called Epidiolex.
When applied to the skin: There isn’t enough reliable information to know if CBD is safe or what the side effects might be.
