Yes, it was home-made...And since there wouldn't have been a way to remove the peanutbutter alone, (which isn't allowed through checkpoints if you read the link I provided), so the whole thing was confiscated.

As to medications? There are certain meds not allowed, but generally most medications aren't removed from you if they're of an emergency nature (meds for allergic reaction or heart/diabetic meds), or you have a number from your doctor (along with a number to talk to the doctor directly), that gives you medical permission to carry it on the plane. And if you're not sure, call the airport with any concerns/questions. They want you to, as it saves both you, other fliers, and themselves time in the check points.

The simple rule is, if you don't need it during the flight, put it in the baggage deemed for the cargo hold.
