It's usually not, but if it's a controlled substance then you really should have backup.
Everyone (basically) carries some pills like vitamins, OTC pain relievers like tylenol etc.
It's only customs who should care at the end of the trip, but if you got 600 unmarked pills, they may take an interest in what that is.
