Could you share your source material? I'm curious if that refers to uncooked weed eaten raw, cooked weed thrown into something like a brownie recipe, or edibles made by concentrating thc in butter or oil.

Inhaled weed would be diluted by breathing in oxygen between hits, while eaten weed, eaten on an empty stomach would slowly and continuously diffuse into the bloodstream of an extended period of time. Maybe that's why people feel like they get higher eating weed.
