How to read a CBD figure

Percentage is content by weight. Milligrams per serving is the more useful number for edibles and beverages, because it tells you the dose rather than the concentration. Where both appear on a certificate they should reconcile: percentage multiplied by ten gives milligrams per gram.

If a label claims a CBD figure the certificate does not support, trust the certificate.
