The answers to these questions are based on the sort of edible you select. If you're eating a store-bought edible, the package label should specify the THC and Cannabidiol (CBD) concentrations (written as a percentage). If you are making your homemade edible base (– for example, butter), the actual quantity of CBD and THC will depend on a number of factors, such as the bud you choose, the recipe's portion sizes, and how the components are added. To get a more accurate answer for the amount of cannabis in your cannabutter, test it. In order to identify this figure, most major edibles manufacturers test their goods at least 3 times.
