THE TAKEAWAY

CBD is one compound in cannabis. Understanding what it is is different from knowing whether a particular product is right for you.

Meet cannabidiol

CBD is short for cannabidiol, a compound found in the cannabis plant. It is different from THC, the cannabinoid mainly responsible for the cannabis “high”. A product described as CBD can still contain THC or other ingredients. [1]

A compound, an ingredient, a medicine?

These words describe different things. A bottle of consumer CBD oil is a finished product with its own ingredients and manufacturing choices. A prescription CBD medicine has a defined formulation and specific approved uses. Evidence for one does not automatically validate the other.

Three things to learn before you buy

  • The format: oil, gummy, capsule, or something applied to the skin.
  • The contents: CBD per serving, other ingredients, and any declared THC.
  • The evidence: what supports the claim, and whether it studied the same product.
