Nope. THC intake with smoking is (pretty much) consistent across people and the dosing feedback from intake to effect is much shorter, whereas edibles hit differently depending on a lot of specific factors (body weight, how much one has eaten/drunk) which means that especially in "social get-high situations" edibles don't really work as intended. Not to mention it's easy to overdose on edibles.
