Cannabidiol (CBD)
Introduction
Cannabidiol(CBD) is a chemical in theCannabis sativaplant. This plant, which contains more than 80 chemicals known as cannabinoids, is also called marijuana or hemp. Two key ingredients in cannabis are CBD and tetrahydrocannabinol (THC). THC is responsible for the intoxicating effects of cannabis, and it might contribute to the plant's health benefits. Unlike THC, CBD is not intoxicating. CBD is available in softgels, tablets, capsules, oils, gums, liquid extracts, and vape juice (for fillable electronic cigarettes). Some of these products contain CBD only, and others contain CBD in combination with other ingredients. A 2017 study concluded that labels of many products containing CBD make inaccurate claims about the amount of CBD in the product, and CBD concentrations in the same product sometimes vary. Moreover, THC (or marijuana) was found in 21% of the products ( References ). (See also Overview of Dietary Supplements .)
