Forest Stream and Lazy Lob

By midwestborn86, in Rules questions & answers

Forest Stream states "while Forest Stream is the active location poisoned characters cannot quest"

Does this mean they simply can't commit to quest?

or

If Lazy lob comes out on a poison free questing party and deals one poison to everyone questing are they all removed from the quest if Forest Stream is the active location

I wondered that myself when I did a playthrough recently, and I treated it as absolute. It simply says "cannot quest," so I had Lazy Lab force everyone out of the quest. Made for a very nasty combo that the encounter deck could whip up.
