Edibles take longer to take effect. It can take two or more hours, depending on what you ate. You can speed this up by letting them dissolve in your mouth and the active components be absorbed by the tissues there. You can go the more or less traditional route with chocolate, gummies, or hard candy. I chose capsules instead.
To address potency most folks will take multiple edibles. I use concentrate to make my capsules each the equivalent of 150 mg of flower. It's fairly easy to increase the potency to the equivalent of a full gram per size 2 capsule. There is a complete section of this forum devoted to edibles.
