I know my tolerance well. I just ate some and will feel something in an hour or so. That's the one thing I dislike about edibles is the amount of time it takes to feel something. On the other hand, edible highs last much longer than smoking.
One positive I can say is all the quest glitches I was getting in my last playthrough have been fixed. So I'm making good progress and also in the process of getting into Sarah Morgan's pants.
I honestly don't see a point in even using space craft in this game. It serves absolutely no purpose. It's a glorified load screen with the occasional combat interaction. Big fail on Bethesda's part here.
