No
I am certain no outside drinks or food allowed.
They do check bags but the body scan is walking through a metal detector only. I highly doubt if you have an unopened or even an opened bag of gummi worms that they will confiscate them. The worst that could happen is they make you or they themselves dispose in the garbage at check-in.
If at all, it would have to be unopened.
I know for sure they dont allow outside food but not so sure about candy.
I haven't seen any signs prohibiting it
They have a strict bag check and body scan when they have an event going on but I haven't seen the day to day security.
