It really doesn't matter whether or not you're supposed to be there.
Should you "accidentally" end up physically in the U.S. you're "fair game" for and within the jurisdiction of their CBP - and subject to U.S. laws.
The golden rule really will have to be don't ever carry cannabis on any flight in any form whatsoever.
Don't ever think you're "safe" because you are on a domestic flight either!
